Who Uses Chem-Crete?

bg
Highway Departments

Highway Agencies, worldwide, face challenges related to maintaining and preserving the massive investment in infrastructure and providing a safe and efficient transportation network. Chem-Crete products, both surface applied and inter-blended with the Portland cement concrete (PCC) can provide cost effective solutions to the most common problems including resistance to deicing salts, freeze/thaw damage, alkali-silica reactivity and many others.

bg
Cities and Municipalities

Cities and municipalities are typically responsible for a wide variety of infrastructure types including water and wastewater treatment facilities, structures, monuments, streets and roads. The Chem-Crete’s product line has a solution for many of the recurring problems that consume both time and limited resources common to most local government agencies. For example, Chem-Crete Pavix CCC-100 can be applied to existing slabs-on-grade (concrete streets, sidewalks, parking areas and others) to greatly improve performance and longevity, particularly in freeze/thaw environments or where deicing salts are used.

bg
Airport Authorities

Airport Authorities, worldwide, operate under very stringent construction and maintenance standards due to safety considerations and to minimize downtime that would impede normal airport operations. Concrete deterioration due to freeze/thaw, application of deicers, alkali-silica reactivity and other mechanisms can greatly affect both safety and operational readiness. Many of these issues can be addressed by application of appropriate Chem-Crete products that make the concrete highly impermeable and thereby minimize moisture and chemical-related damage.

bg
Engineers and Architects

Engineers and Architects are frequently tasked with writing project specifications and selecting appropriate materials. PCC is the most widely used construction material in the world and therefore is used in a variety of applications including highways, airfields, port facilities, buildings and numerous others. Chem-Crete products can be used to increase the longevity and performance of PCC used in the most challenging environments

bg
Contractors and Builders

Contractors are required to conform to both plans and specifications when constructing highways, airfields, parking areas, etc. They are frequently required to warranty their work for extended time periods against non-load related cracking and other forms of concrete deterioration. Chem-Crete has developed number of surface applied and internally mixed products to promote enhanced curing and minimize the influence of water and externally applied chemicals. In addition, specialty Chem-Crete products have been shown to minimize early plastic (drying) shrinkage cracking when used in conjunction with adequate curing thereby providing added insurance against this construction-related defect.

Pavements & Structures Protection

Concrete does not break down overnight. It fails one freeze-thaw cycle, one chloride ion penetration, one hairline crack at a time, until a structure built to be last decades starts showing its age in years. In pavement construction, both concrete pavements and asphalt pavements share similar durability issues and concerns. That’s the problem International Chem-Crete set out to solve nearly 50 years ago, and it still continues to be the problem our Concrete Structures Protection line is designed to conquer. Every road, runway, bridge deck, and parking structure is under constant attack from forces most people never think about, such as deicing salts eating away reinforcing steel, water and vapor working through pores and micro-cracks, and alkali-silica reaction slowly expanding concrete from within. These threats can't be ignored for any structural construction company that is responsible for sustainable structures to be used for 30, 40, or 50 years. It's a budget problem waiting to happen. A proactive pavement preservation strategy pays for itself many times over.

Why Pavement Preservation Beats Repair

There's an old saying in infrastructure management: the best time to protect a pavement is before it needs repair, not after. When cracking, scaling, spalling, or corrosion of the rebar occurs, you are no longer “maintaining”; you are “rebuilding,” and rebuilding costs many times what preservation does. Our pavement preservation treatment and products are specifically designed to get ahead of that curve, penetrating and lining the pore structure of concrete so water, chlorides, and moisture can't do the damage they're designed to do. Three products, three ways to protect:
  • CHEM-CRETE® MCE™: A multi-crystalline permeability reducing admixture (PRA), mixed directly into the fresh concrete batch, that waterproofs the whole concrete matrix from within. Ideal for any structural construction company that wants durability-engineered, sustainable infrastructure from the start rather than added on later. MCE is simply dosed to the concrete mixture as any other admixture.
  • CHEM-CRETE® PAVIX® CCC® 100: A topical treatment that can be used on green and cured concrete alike, blocking pores and lining capillaries against water, moisture, and ice adhesion. Built as a concrete sealer for airport runways, highway pavements, and bridge decks, where reliability under constant traffic and weather stress is non-negotiable.
  • CHEM-CRETE Greenicer: A green deicer and crystalline waterproofing and restoration treatment for concrete pavements. It is used for pavement treatment and bridge deck protection against ice adhesion.
  • CHEM-CRETE ASP®: A silicone-modified asphalt sealer custom-made for asphalt pavements, enhancing pavement durability and extending service life on the asphalt side of a project with the same protect-first approach.

Structural Protection Services Built on Real Chemistry

It’s not just the products that tie this category together, but the way it’s done. International Chem-Crete does not provide one-size-fits-all pavements. We provide structural protection products based on years of laboratory and field-tested chemistry, aimed at the specific mechanisms that actually cause concrete and asphalt failures: chloride ion penetration, freeze-thaw cycling, ASR, biological attack, ice adhesion, and moisture flow through both positive and negative sides of a structure. That distinction matters for :
  • Highway departments managing thousands of lane-miles
  • Municipalities responsible for aging infrastructure
  • Airport authorities where downtime isn't an option
  • Engineers writing specifications that are required to last for years, decades, or even generations.
Whether it is protecting a freshly poured structure or extending the life of an existing structure, this category is designed to be the foundation for pavement preservation programs that actually deliver, resulting in fewer emergency repairs, longer asset life, and lower total cost of ownership. Protecting pavements and structures isn't about putting on a sealer and hoping for the best. It's about understanding the actual deterioration of concrete and asphalt and then engineering a solution that interrupts that deterioration at the point of its origin. That's what nearly five decades of International Chem-Crete research has been built around, and why any structural construction company looking for a long-term pavement preservation partner keeps coming back to this category. FAQs Que : What is the difference between concrete crystalline waterproofing and water-repelling Ans : Crystalline waterproofing is pore-blocking or filling for reducing water permeability through the precipitation of crystals (hygroscopic and/or hydrophilic crystals) within the concrete pores. Water-repelling is just establishing hydrophobicity at the pore surfaces that reduces water absorption under insignificant hydrostatic pressure. Que : What's the difference between a topical treatment and an admixture for pavement protection? Ans : A topical treatment like PAVIX CCC-100 is applied to the surface of green or cured concrete, penetrating and then blocking existing pores and capillaries after placement. The resulting concrete automatically contains a protective density from the very beginning, as an admixture is added to the concrete when it is being mixed, leading to pore blocking for the wall concrete structure. Que : Can these products be used on existing pavements, or only new construction? Ans : MCE is used only in new construction. PAVIX CCC-100 is formulated to work on cured, in-service concrete as well as new pours, making it a practical option for preservation programs on existing highways, bridges, and airport pavements. ASP is applicable to new and existing asphalt pavement. Que : Is asphalt protection different from concrete protection? Ans : Yes. Asphalt and concrete have different chemistry and deteriorate through different mechanisms, which is why CHEM-CRETE ASP® uses a silicone-modified formulation specifically suited to asphalt, separate from the crystalline waterproofing chemistry used on concrete. From a functionality perspective, both pavement durability solutions target pore blocking and water repellency.

Concrete Admixtures and Enhancers

Every strong concrete structure starts long before the pour, in the mix design. Get the chemistry right at that stage, and you're building in strength, density, and water resistance with a concrete durability solution. That's the idea behind International Chem-Crete's Concrete Admixtures and Enhancers line to provide exceptionally durable concrete, built from the inside out. This is very important in pavement construction, and more particularly for pavement durability with 1L cement problems (or PLC concrete problems). For any structural construction company that's watched a "perfectly good" pour crack, spall, or let water through within a few years, the message is simple: the mix matters as much as the placement. Our Integral waterproofing admixture (concrete crystalline admixture) is formulated to provide concrete with the internal resistance it needs to perform for decades, not just pass inspection on day one.

Why the Right Admixture Changes Everything

Not all concrete admixtures have the same purpose, and that's exactly the point. Among concrete admixture companies, International Chem-Crete has spent nearly 50 years focused on one core problem: how do you ensure concrete durability and make concrete inherently resistant to the things that destroy it, such as water intrusion, chloride penetration, alkali-silica reaction, and drying shrinkage, rather than just dealing with the symptoms after the concrete is in place. This focus is reflected in the products that form the core of this category:
  • CHEM-CRETE® MAG-SIL®: A powdered intermixed concrete enhancer that's part of Chem-Crete's dual crystallization family. Incorporated at the batching stage (much like fly ash, slag, or silica fume), MAG-SIL enhances the compressive and flexural strength, increases workability, lowers permeability, reduces ASR potential, and cuts chloride intrusion, all from within the mix itself.
  • CHEM-CRETE® MCE™: A multi-crystalline liquid admixture is designed to block the pores and the concrete matrix from the inside and improve long-term concrete durability and performance before the structure ever faces its first freeze-thaw cycle or deicing season. As a permeability-reducing admixture (PRA), it is ideal for sustainable infrastructure and pavement construction. MCE is simply dosed into the mixture as a concrete enhancer, similar to dosing other concrete liquid admixtures.
Both are based on the same principle: concrete admixtures for waterproofing should not merely be applied to the surface to prevent water from seeping through; they should change the internal pore structure of the concrete and stop water from seeping in in the first place.

Finding the Best Admixture for Concrete, for the Job

There's no single answer to what's the best admixture for concrete; it depends on what the structure needs to resist and when in the process you're able to intervene. If you're a contractor, engineer, or specifier looking to build resistance in at the batching stage rather than treat problems after the fact, MAG-SIL and MCE give you options that work with standard batching processes and familiar SCM handling, without complicating your mix design workflow. It's also worth noting that this category is not the place for an accelerator admixture in concrete or concrete admixtures for high early strength, where the goal is faster set times or early-age strength gain rather than long-term durability. Chem-Crete's enhancers are designed for the opposite end of the timeline: long-lasting performance, when the structure is dealing with real-world traffic, weather, and chemical exposure rather than a 28-day test cylinder.

Built for Structures That Can't Afford to Fail

Concrete is the material that's expected to last, which is why it's a choice specified by all kinds of entities, including highway departments, airport authorities, municipalities, and engineers. When the underlying mix is fighting permeability, ASR, and chloride intrusion from day one, that promise gets a lot easier to keep. That's the benefit a structural construction company reaps when it addresses these admixtures in its project mix design in the beginning. It leads to fewer surprises during the service life of the pavement, bridge, or structure, and less need for repair and retrofit down the line. Concrete Admixtures and Enhancers is a foundational category in the Chem-Crete lineup, and that's by design. Getting the internal chemistry right is often the single highest-leverage decision on a project, long before anyone talks about sealers, coatings, or repairs. FAQs Que : Can MAG-SIL and MCE be used together in the same mix? Ans : Each of MCE and MAG-Sil is a crystalline waterproofing admixture that also enhances concrete Compressive Strength. Each is designed to work as a standalone enhancer added at batching, and project-specific compatibility should be confirmed with our technical data sheets or our team, since mix designs vary by project and local materials. Que : Do these admixtures replace the need for surface sealers or waterproofing treatments? Ans : Not entirely. They reduce permeability and improve internal resistance to water and chlorides, but can still be used in conjunction with surface protection in many projects to provide maximum long-term protection, especially in high exposure environments. This depends on the project requirement. Que : How are these products added to a concrete mix? Ans : MAG-SIL is a powdered admixture added at the time of batching, similar to fly ash or silica fume, or incorporated into the cement at the point of manufacture. MCE is also introduced during batching to work throughout the concrete matrix; it can also be added to a concrete trans-mixer before placement.

Water Proofing & Moisture Blockers

Water is persistent. It doesn’t need to force its way through concrete; a tiny pore, hairline crack, or years of unchecked vapor pressure can be enough to create an entry point. And once it happens, the damage escalates rapidly: rusty rebar, spalling, scaling, mildew growth on concrete, mold growth in concrete, ruined flooring, failed roofs. A reliable concrete moisture blocker isn't a nice-to-have on a structure meant to last decades; it's foundational. International Chem-Crete built its Waterproofing & Moisture Blockers line around that reality, addressing everything from straightforward concrete waterproofing to subfloor vapor condensation and subfloor mold problems that surface long after a project is considered finished.

Why "Waterproof" Isn't One-Size-Fits-All

Ask ten contractors what concrete waterproofing means, and you'll get ten different answers, because the right approach depends entirely on where the water is coming from and what the structure needs to resist. A below-grade foundation dealing with hydrostatic pressure needs a different basement concrete sealer than a rooftop dealing with UV exposure and ponding water, and a subfloor dealing with vapor emission needs something different again. That's why this category isn't a single product, but a system of solutions:
  • CHEM-CRETE® SOFIX® CCC® 100 & CCC® 700: Hydrophilic and hygroscopic concrete vapor blockers, formulated for vapor transmission rates up to 12 and 18 lbs per 1,000 ft² every 24 hours. Where subfloor vapor condensation drives mildew growth on concrete and flooring failures, these products are designed to intercept moisture before it ever reaches the surface.
  • CHEM-CRETE® YUFIX® CCC® 1000: A water-based concrete and masonry water repellent and crystalline penetrating sealer, and a practical concrete sealer for surfaces that need long-term repellency and adhesion strength without changing their appearance.
  • CHEMCRETEX® CEM600: A crystalline cementitious coating that works its way into the concrete's own pore structure, forming genuine concrete moisture blockers from within rather than just setting on top of it.
  • CHEM-CRETE® CCC® 150: A cementitious coating built as a durable, code-friendly basement concrete waterproofing and general-purpose barrier waterproofing coating against water intrusion.
  • CHEM-CRETE® FLEX CCC900: A two-component, acrylic-modified, flexible cementitious coating designed to accommodate structural movement, giving it a natural concrete crack-healing ability in places where rigid coatings tend to fail and lose adhesion strength.
  • CHEM-ROOF 550: A one-component, water-based elastomeric coating built for concrete waterproofing on roof systems, standing up to weather, UV, and ponding without the seams and failure points of traditional membranes.
  • CHEM-SHIELD CCC800: An architectural textured structural coating that combines moisture protection with a finished, presentable surface that doesn't have to look purely industrial.

Choosing the Right Concrete Waterproofing & Moisture Blockers

The common denominator across all eight products is the same philosophy: a concrete moisture barrier should match the water problem it's solving, not just check a box on a spec specification sheet. Hydrostatic pressure from groundwater calls for a different chemistry than moisture vapor moving up through a subfloor, and a concrete sealer chosen for a basement wall will look nothing like the coating built for a roof deck. For departments of transportation, municipalities, airport authorities, engineers, and contractors specifying protection on real infrastructure, that distinction matters. Getting the waterproofing wrong doesn't just mean a repair bill; it means water finding its way back to the rebar, the finishes, or the structure underneath, often in places that are expensive and disruptive to access again.

Protection That Starts at the Source

Every product in this line shares Chem-Crete's core philosophy: understand exactly how and where water is entering a structure, then design a barrier that stops it at that specific point, whether it’s a capillary network, rooftop membrane, construction joint, or a recurring crack. That's what nearly five decades of research and field testing look like in practice, and it's why this category remains one of the most specified in the Chem-Crete lineup. FAQs Que : How do these products address subfloor mold problems and vapor issues under flooring? Ans : SOFIX CCC 700 and SOFIX CCC 100 are concrete vapor moisture blockers designed to control vapor emission and subfloor vapor condensation before it reaches flooring adhesives or finishes, addressing the root cause of subfloor mold problems and mildew growth on concrete rather than just masking the symptoms. Que : What's the difference between a basement concrete sealer and a cementitious coating? Ans : A basement concrete sealer like SOFIX CCC 700 and SOFIX CCC 700 are is typically a thinner moisture treatment for surfaces that need protection internally without a visible film. A cementitious coating like CCC 150 or CEM600 builds a thicker, more durable barrier, which is often the better choice for structures under active hydrostatic pressure. Que : Can FLEX CCC 900 actually heal cracks, or does it just cover them? Ans : FLEX CCC900 is a flexible cementitious coating engineered to accommodate structural movement, so it bridges and seals hairline cracks as they form rather than cracking alongside them. This helps maintain adhesion strength over time, compared with rigid coatings that lose contact once crack movement occurs.

Heritage

Protecting Historic Structures With Modern Waterproofing Technology

Historic buildings require specialized care to preserve their architectural character while protecting them from moisture, weather, and long-term deterioration. To protect historic structures, Chem-Crete provides advanced solutions, including CHEM-CRETE® HERITAGE CCC® 110, made to preserve the performance of older structures. Our approach combines proven waterproofing technology with practical construction expertise to protect masonry, exterior surfaces, foundations, and other vulnerable areas without compromising the character of heritage properties.

Exterior Services For Historic Structures for Long-Term Protection

Historic exteriors can experience deterioration from rain, humidity, freeze-thaw cycles, water intrusion, and aging construction materials. Our exterior services for historic structures address these challenges through targeted surface protection and waterproofing treatment of historic properties. Chem-Crete solutions reduce moisture penetration and protect concrete and masonry surfaces against conditions that contribute to cracking, staining, spalling, and structural deterioration. Getting the assessment and product selection right is essential when working with buildings that require careful preservation and heritage structure preservation.

Heritage Structure Waterproofing

Water intrusion is one of the most common threats to historic structures. Effective heritage structure waterproofing stops moisture before it penetrates vulnerable surfaces and contributes to long-term damage. Chem-Crete offers specialized waterproofing technologies designed for concrete, masonry, and other construction applications, including CHEM-CRETE® HERITAGE CCC® 110, a topical, dual-crystalline treatment that penetrates existing surfaces without leaving a visible residue. These treatments form a protective, colorless sealer while allowing project teams to address the specific characteristics and requirements of an existing historic structure.

Heritage Masonry Waterproofing Solutions

Historic masonry requires a thoughtful approach because traditional brick, stone, mortar, and concrete may react differently to modern construction treatments. Our heritage masonry waterproofing solutions protect exterior surfaces from moisture while supporting the preservation objectives of the project. HERITAGE CCC 110 works within the pores of the material rather than sealing the surface shut, so it reduces water absorption and permeability, improves surface durability, and limits the effects of repeated moisture exposure while supporting the structure's ability to breathe.

Waterproofing Historical Buildings

Waterproofing Historical Buildings requires more than simply applying a conventional coating. Historic properties may contain aging substrates, unique masonry assemblies, decorative elements, and construction methods that require specialized consideration for proper architectural conservation. Chem-Crete technologies, including HERITAGE CCC 110, give project professionals a way to address moisture-related concerns across concrete and masonry applications. By reducing water penetration and improving surface protection, the right waterproofing treatment preserves vulnerable areas and supports the long-term performance of the building.

Key Benefits of Heritage Waterproofing

A properly selected waterproofing treatment can help historic property owners, restoration professionals, architects, and contractors manage moisture-related deterioration while supporting long-term preservation objectives.
  • Moisture protection: Reduces water penetration through concrete and masonry surfaces
  • Surface durability: Improves resistance to weathering and environmental exposure
  • Historic preservation: Protects existing structures while maintaining their architectural character
  • Vapor permeability: HERITAGE CCC 110 reduces water permeability with little to no effect on vapor permeability, allowing existing structures to continue to breathe.
  • Long-term performance: Extends the service life of treated construction materials
  • Versatile applications: Solutions apply across a range of historic concrete, masonry, and exterior construction projects, applied using handheld sprayers, commercial sprayers, rollers, or paint brushes.

Protect Historic Structures for the Future

Preserving a historic building requires balancing its original character with the need for modern protection. Chem-Crete provides construction technologies that help restoration and construction professionals solve moisture penetration, surface deterioration, and durability problems. Whether the project involves exterior services for historic structures, heritage masonry waterproofing, or Waterproofing Historical Buildings, selecting the appropriate treatment is an important part of architectural conservation and protecting valuable structures for years to come. Frequently Asked Questions Que : What is heritage structure waterproofing? Ans : Heritage structure waterproofing is the application of specialized moisture-management and waterproofing treatments to historic or heritage buildings. The goal is to reduce water penetration and protect vulnerable construction materials from moisture-related deterioration while respecting the characteristics and preservation requirements of the existing structure. Que : Why is waterproofing important for historic buildings? Ans : Water can contribute to staining, cracking, freeze-thaw deterioration, corrosion, masonry damage, and other forms of deterioration. The right waterproofing limits moisture exposure and supports the long-term durability of historic concrete and masonry surfaces. Que : Can historic masonry be waterproofed? Ans : Yes. Heritage masonry waterproofing treatments, such as HERITAGE CCC 110, work on brick, stone, concrete, and masonry applications. However, the existing substrate, construction type, condition, exposure, and preservation requirements should be evaluated before selecting a treatment. Que : What should be considered when waterproofing a historical building? Ans : Important considerations include the condition and composition of the existing substrate, sources of water intrusion, climate, drainage, vapor movement, appearance requirements, and the preservation objectives of the project. Que : Who should handle historic exterior waterproofing? Ans : Historic exterior waterproofing should be planned with professionals experienced in restoration, construction materials, and moisture management. Architects, engineers, contractors, preservation specialists, and qualified product professionals can help determine the appropriate approach for a particular structure.

Under Water Applications

Advanced Solutions for Demanding Underwater Applications

Underwater applications demand materials engineered to perform where conventional products fail. As an experienced partner, Chem-Crete provides construction chemical solutions built for water exposure, pressure, difficult access, and challenging substrate conditions. Our technologies support contractors, engineers, municipalities, and infrastructure professionals working on concrete and steel structures that require repair, sealing, grouting, or protection below the waterline.

Crack Sealing in Swimming Pools

Cracks in swimming pool structures rarely stay dry long enough for conventional repair materials to bond properly. CHEM-UNDERWATER INJECT and CHEM-GUARD UNDERWATER solve that problem directly. It's a two-component epoxy injection resin engineered to repair wet structural cracks above the waterline or fully submerged, with a low viscosity and long pot life that lets it flow into and seal the full length of a crack before it begins to cure. For pool decks, shells, and surrounding structural concrete, that means crack sealing in swimming pools can happen without draining the pool or waiting for the surface to dry out first.

Stopping Water Leaks in Hydraulic Structures

Dams, tunnels, retaining walls, and other hydraulic structures put constant pressure on every joint and crack in the concrete, and a leak that starts small rarely stays that way. CHEM-UNDERWATER INJECT and CHEM-GUARD UNDERWATER are formulated to fill and seal voids and subsiding cracks under real injection pressure, stopping water leaks in hydraulic structures at the source rather than masking them on the surface. They meet ASTM C881 Type II, Class B & C, giving engineers a product they can specify with confidence on critical infrastructure.

Sealing Precast Cofferdam

Cofferdams place enormous demands on sealing systems, since the joints between precast sections have to hold back water under constant hydrostatic pressure from day one. CHEM-GUARD UNDERWATER is built for exactly this kind of application. It's a two-component, 100% solids hydrophilic epoxy gel adhesive that cures and hardens fully submerged, forming a heavy-bodied, non-sagging seal at the joints. Sealing precast cofferdam sections with a product designed to cure underwater removes the guesswork that comes with trying to seal joints in dry conditions that won't stay dry for long.

Sealing Concrete Pile

Pilings are submerged or intermittently exposed for the life of the structure, which means the seal protecting them has to perform in the same conditions indefinitely. CHEM-GUARD UNDERWATER is purpose-built for pilings, drainage canals, abutments, structural supports, and other steel or concrete elements sitting in fresh or salt water or in splash zone exposure. Sealing concrete pile surfaces with a hydrophilic epoxy gel that hardens underwater protects the structure exactly where conventional coatings struggle most.

Underwater Cementitious Grouting

Grouting work below the waterline calls for a material that flows into place and holds under pressure without washing out. CEM9000 is built for exactly that. It's a ready-to-use, one-component, non-shrink cementitious grout made from Portland cement, graded silica sand, and flow-improvement compounds, mixed on site with water alone. Its low washability keeps the mix intact as it's placed underwater, while the non-shrink formulation and early high strength make it suited to underwater cementitious grouting projects like setting bolts and anchor bars, filling cavities, and repairing structural voids.

Key Benefits of Underwater Construction Solutions

Specialized construction materials give professionals a direct way to address the unique challenges of submerged concrete and steel infrastructure.
  • Underwater cure performance: CHEM-UNDERWATER INJECT and CHEM-GUARD UNDERWATER are engineered to cure fully submerged, not just tolerate moisture.
  • Crack and leak control: CHEM-UNDERWATER INJECT fills and seals cracks and voids under injection pressure, stopping leaks at the source.
  • Joint and pile protection: CHEM-GUARD UNDERWATER forms a non-sagging seal on cofferdam joints, pilings, and other submerged steel and concrete elements.
  • Grouting flexibility: CHEM-UNDERWATER INJECT doubles as a grouting material for bolts and anchor bars in underwater applications.
  • Specification-ready performance: Both products meet ASTM C881 requirements for structural epoxy systems.

Reliable Solutions for Water-Exposed Infrastructure

Underwater construction rewards planning and the right material for the job, not a one-size-fits-all coating. From crack sealing in swimming pools and stopping water leaks in hydraulic structures to sealing precast cofferdam joints, sealing concrete pile surfaces, and underwater cementitious grouting, International Chem-Crete provides technologies engineered specifically for submerged and water-exposed conditions. With the right product matched to the right application, professionals can stop deterioration at the source and protect critical infrastructure for the long term. Frequently Asked Questions Que : Can concrete cracks really be sealed while still underwater? Ans : Yes. CHEM-UNDERWATER INJECT is formulated to cure fully submerged, so cracks in pool structures, tunnels, and hydraulic infrastructure can be injected and sealed without draining or drying the surrounding area first. Que : How does CHEM-UNDERWATER INJECT stop leaks in hydraulic structures? Ans : It's a low-viscosity epoxy resin injected under pressure, where it flows into and fills existing cracks and voids before curing, sealing the leak path at the source rather than covering it on the surface. Que : How is a precast cofferdam joint sealed underwater? Ans : CHEM-GUARD UNDERWATER, a hydrophilic epoxy gel adhesive that cures underwater, is applied to the joint and left to harden in place, forming a non-sagging seal even under constant water exposure. Que : What makes a product suitable for sealing concrete piles? Ans : A piling sealant needs to cure and perform indefinitely in submerged or splash zone conditions. CHEM-GUARD UNDERWATER is formulated specifically for steel and concrete pilings exposed to fresh or salt water on a constant or intermittent basis. Que : What makes CEM9000 suitable for underwater cementitious grouting? Ans : CEM9000 is a one-component cementitious grout formulated with low washability, so it resists dispersing into the surrounding water as it's placed. Combined with its non-shrink formulation and pumpable consistency, it's suited to filling cavities, setting anchor bars, and repairing structural voids underwater.

Freezers & Cold Storages

Cold storage environments push flooring to its limits. Sub-zero temperatures, constant condensation, heavy pallet traffic, and aggressive cleaning cycles all work against a standard concrete floor, and most coating systems simply aren't formulated to cure in the cold in the first place. That's the gap CHEM-FREEZER is made to close. As a freezer coating and refrigerator coating engineered specifically for sub-zero application, it gives facility owners and contractors a way to protect concrete floors in conditions where ordinary epoxy systems fail before they ever set.

Freezer Coating and Refrigerator Coating for Sub-Zero Environments

Most epoxy coatings need warmth to cure properly, which makes them a poor fit for commercial freezers, cold stores, and refrigerated facilities that never warm up without shutting down. CHEM-FREEZER is a two-component, solvent-free, 100% solids liquid epoxy binder system formulated to cure at temperatures below 0°F (-18°C). That single distinction is what separates a genuine freezer coating from a refrigerator coating adapted from a standard product line, and it's why CHEM-FREEZER is used across dairies, milk processing centers, fisheries, meat processing facilities, and cold stores operating at extremely low temperatures year-round.

Freezer Epoxy Coating Built to Cure Below Zero

A freezer epoxy coating has to do more than resist moisture and traffic. It has to actually cure in an environment most epoxy chemistry can't tolerate. CHEM-FREEZER is a sub-temperature epoxy purpose-built for that challenge, combining epoxy resin and hardener into a clear liquid binder formulated for temperatures below -18°C. Mixed with dry silica sand, it becomes a custom-designed epoxy repair mortar suited to deep-section concrete floor repairs, giving facility teams a single system that handles both coating and structural repair in the same sub-zero environment.

Cold Storage Floor Coating and Freezer Floor Coating

A cold storage floor coating and a freezer floor coating face the same core problem from different angles: constant temperature extremes wear down concrete faster than almost any other operating environment. CHEM-FREEZER addresses both by curing reliably in the cold rather than requiring facilities to warm the space before installation, a requirement that's rarely practical in an active cold storage or freezer operation.

Freezer Floor Repair and Walk-in Cooler Repair

Freezer floor repair and walk-in cooler floor repair both have the same limitation: the space can't always be taken out of sub-zero operation long enough for a standard repair mortar to cure. CHEM-FREEZER solves that directly. Because it's formulated to set at temperatures below -18°C, it can be used to repair deep sections of concrete floor without shutting down refrigeration or waiting for conditions to warm. For a walk-in cooler floor repair where downtime is expensive, that's the difference between a quick, in-place fix and pulling a facility out of service.

Key Benefits of Cold Storage Flooring Solutions

Specialized flooring and surface protection can help facilities manage the demanding conditions associated with refrigerated environments.
  • Moisture protection: Reduces water penetration and moisture-related deterioration in concrete surfaces.
  • Durable surfaces: Resists everyday traffic, abrasion, and operational wear.
  • Temperature considerations: CHEM-FREEZER is engineered specifically for environments where floors experience sub-zero operating temperatures.
  • Easy maintenance: A properly selected surface supports routine cleaning and maintenance requirements.
  • Long-term concrete protection: Protects existing concrete and extends its service life.

Protect Your Cold Storage Flooring

Cold storage and freezer facilities need a flooring system built for actual operating conditions, not ideal ones. From freezer coating and refrigerator coating applications to freezer epoxy coating, cold storage floor coating, and freezer floor coating projects, CHEM-FREEZER gives contractors and facility owners a sub-temperature epoxy that actually cures where it's applied. Whether the need is a full floor coating or a freezer floor repair on a section that's already failing, having a system built for sub-zero conditions means the work gets done without shutting the facility down. Frequently Asked Questions Que : Why aren't standard epoxy coatings suitable for freezers? Ans : Most epoxy systems require warmth to cure and simply fail to set at freezer or refrigerator temperatures. CHEM-FREEZER is formulated specifically to cure at temperatures below 0°F (-18°C), which is why it works as a freezer coating and refrigerator coating where conventional products fail. Que : What temperatures can CHEM-FREEZER be applied in? Ans : CHEM-FREEZER is designed to cure at temperatures below -18°C (0°F), making it suitable for commercial freezers, cold stores, and refrigerated facilities that operate at sustained sub-zero temperatures. Que : Can CHEM-FREEZER be used for floor repairs as well as coating? Ans : Yes. Mixed with dry silica sand, CHEM-FREEZER becomes a custom-designed epoxy repair mortar for deep-section concrete floor repairs, making it suitable for both freezer floor repair and walk-in cooler floor repair projects. Que : Does the facility need to be warmed up before applying CHEM-FREEZER? Ans : No. CHEM-FREEZER is engineered to cure in sub-zero conditions, so it can be applied and cured without shutting down refrigeration or waiting for the space to warm. Que : What industries typically use this kind of freezer flooring solution? Ans : CHEM-FREEZER is commonly used in dairies and milk processing centers, fisheries and meat processing facilities, and any cold storage operation that needs reliable flooring and repair performance at temperatures below -18°C.

Structural Grouts

A base plate that isn't fully supported is a failure waiting to happen. Under a turbine, a crane rail, or a bridge bearing, even a small void beneath the plate concentrates load onto a fraction of the surface it was designed to spread across, and over time that concentrated stress cracks concrete, loosens bolts, and throws heavy equipment out of alignment. International Chem-Crete's Structural Grouts line completely closes that gap, giving engineers and contractors a grout for every kind of base plate grouting, machinery installation, and structural connection that has to carry real load from day one.

Epoxy Grout for the Heaviest Loads

When a structure faces constant dynamic loading, high heat, or aggressive chemical exposure, cementitious grout isn't always enough. That's where CHEM-POXY GROUT E999 comes in. It's a three-component, solvent-free, 100% solids epoxy grout engineered for exactly this kind of demand: high-speed turbines and centrifuges, bridge bearings, crane and transport rails, tie bars, and new or old machine base plates. As an epoxy grout, E999 brings advantages cementitious systems can't match. It's moisture-insensitive, ultra-low creep, and highly flowable down to clearances as tight as 13mm, with compressive strength reaching nearly 17,000 psi and heat resistance up to 97°C. For base plate grouting under heavy dynamic or static loads, that combination of strength and flow means the epoxy grout fills every void under the plate, not just the ones that are easy to reach.

Controlled Expansion Grout for Precision Alignment

Not every application calls for epoxy. CEM982 is a controlled expansion grout built specifically for projects where precise, predictable movement matters as much as strength. It's a ready-to-use, one-component, cementitious grout engineered with a two-stage expansion system, delivering 2% restricted and 5% non-restricted expansion in both its plastic and hardened states. That controlled positive expansion makes CEM982 ideal for precision alignment work: machinery bases, train rails, subway rails, gantry cranes, and equipment bases in power plants, paper mills, and water treatment facilities. With compressive strength reaching more than 13500 psi at 28 days, CEM982 qualifies as a high-compressive-strength grout in its own right, and its high-sulfate-resistant cement formulation makes it a strong fit for humid or corrosive environments like food processing plants and sewage treatment facilities.

Non-Shrink Construction Grout for Everyday Structural Work

For general-purpose structural grouting where shrinkage simply can't be tolerated, CEM310 fills that role. It's a ready-to-use, one-component, flowable grout that complies with ASTM 1107 Type B, formulated with an inorganic shrinkage-compensating additive that keeps the mix dense and dimensionally stable from initial set through final cure. As a non-shrink construction grout, CEM310 is used to grout structural columns, heavy machinery bases, post-tensioning cables, anchor bolts, precast T-joints, and bearing plates, along with large-scale repairs to damaged concrete structures and honeycombing. It reaches compressive strength over 11,000 psi at 28 days, remains stable under compressive loading, impact, and continuous vibration, and resists oil and water penetration once cured.

Choosing the Right Flowable Grout for the Job

All three products in this category share one property that makes them practical on real job sites: each is available as a flowable grout, capable of being poured or pumped into tight voids and hard-to-reach cavities without segregating or leaving air pockets behind. Flowability alone doesn't decide the right product for a project, though:
  • Epoxy grout (E999): the right choice where chemical resistance, heat, and dynamic loading are the priority
  • Controlled expansion grout (CEM982): the right choice where alignment precision matters as much as load-bearing strength
  • Non-shrink construction grout (CEM310): the right choice for the everyday structural grouting work that makes up most job sites
For highway departments, contractors, and engineers specifying grout for infrastructure that must perform for decades, that distinction isn't academic. Base plate grouting done with the wrong product shows up fast: loosened bolts, cracked pedestals, and equipment slowly drifting out of alignment. Getting the grout right the first time protects the investment sitting on top of it.

Frequently Asked Questions

Que : What's the difference between an epoxy grout and a cementitious grout like CEM310 or CEM982? Ans : Epoxy grout (E999) offers higher chemical and heat resistance with ultra-low creep, suited to heavy dynamic loads. Cementitious grouts like CEM310 and CEM982 are more economical for general structural grouting and precision alignment work. Que : When should a controlled expansion grout be used instead of a standard non-shrink grout? Ans : Use a controlled expansion grout like CEM982 when precise, predictable movement is critical, such as aligning machinery bases or rails. A standard non-shrink grout like CEM310 suits general base plate grouting where alignment precision isn't the priority. Que : Can these grouts be used for large-scale repairs, not just base plate grouting? Ans : Yes. CEM310 and CEM982 both work in large-scale shuttered repairs, including retaining walls, column extensions, and honeycomb repairs, beyond their standard base plate and machinery grouting use. Que : Does CHEM-POXY GROUT E999 need special conditions to cure properly? Ans : Yes. E999 shouldn't be applied below +10°C, and the substrate moisture content must stay under 5%. Under proper conditions, it reaches final cure within 7 days. Que : How much weight can these grouts support once cured? Ans : E999 reaches close to 17,000 psi, CEM982 nearly 13,500 psi, and CEM310 over 11,000 psi at 28 days, all suited to demanding structural applications like turbines, cranes, and machinery bases.

Water Cutoff & Polyurethane Grouts

Water doesn't wait for a convenient repair window. A crack that starts weeping today can be gushing by tomorrow, and by the time anyone notices, the leak has already found the path of least resistance through concrete, masonry, or a pipe penetration. International Chem-Crete's Water Cutoff & Polyurethane Grouts line exists for exactly that moment: fast-reacting materials built to stop water on contact, whether the job is plugging active pipe penetrations, sealing a hairline crack, or shutting down a high-pressure gusher underground.

Instant Plugs for Active Leaks

When water is actively running, there's no time for a product that needs ideal conditions to work. CEM290-R and CEM290-H are hydraulic cement plugging compounds built for exactly that scenario. CEM290-R sets in 3 to 5 minutes even underwater, while CEM290-H sets in just 45 seconds, both packed by hand directly into the leak until the flow stops. Both are used above or below grade, in basements, tunnels, sewage systems, dams, and swimming pools, anywhere plugging active pipe leaks and seepage has to happen immediately, not after the area dries out. That speed matters most when plugging active leak points that are already moving water. For pipe penetrations specifically, CHEM-CRETE DRY OAKUM and CHEM-CRETE PIPE PLUG work as a system. Dry Oakum is a tar-free jute fiber rope that's packed into the gap around a pipe or duct before a polyurethane resin is applied, giving the resin something to grip and expand against. CHEM-CRETE PIPE PLUG takes that a step further as a self-contained kit: a fiber-filled polyurethane grout that expands 10 to 12 times its original size on contact with water, curing into a tough, corrosion-resistant foam plug in minutes. Together, they're a reliable answer for plugging active pipe penetrations in wastewater plants, reservoirs, tunnels, utility pipes, and manholes where a leak can't be scheduled around. For plugging utility pipe openings specifically, the kit gives crews an instant, ready-to-use option.

Polyurethane Injection Foams for Every Kind of Crack

Not every leak calls for hand-packed cement. For cracks and joints that need to be injected under pressure, Chem-Crete offers three polyurethane foam systems, each built for a different situation. CHEM-CRETE RIGID FOAM CCC530 is a two-component, hydrophobic system that expands up to 16 times on contact with water, purpose-built for dead cracks and gushing, high-pressure water in wastewater plants, reservoirs, tunnels, and foundations. It's also effective for soil stabilization and grout curtains, going well beyond simple crack repair. CHEM-CRETE HYDRO FOAM CCC526H is a one-component, hydrophilic foam designed for moving cracks in continuously moist environments, where a rigid, hydrophobic material would eventually crack again as the structure shifts. CHEM-CRETE FLEX FOAM CCC524 splits the difference: a two-component, low-viscosity, flexible resin that expands up to 5 times and is built specifically for moving cracks, expansion joints, and hairline cracks that need to flex along with the structure rather than fight it.

Choosing the Right Product for the Leak

Picking between these systems comes down to two questions: is the crack moving, and how much water pressure is behind it?
  • Dormant, non-moving crack under heavy water pressure: Rigid Foam CCC530
  • Moving crack in a continuously wet or submerged environment: Hydro Foam CCC526H
  • Moving crack or expansion joint that isn't constantly wet: Flex Foam CCC524
  • Water actively running right now: CEM290-R, CEM290-H, or the Pipe Plug system, all built to stop water on contact
For highway departments, municipalities, and contractors managing water infrastructure, that distinction is the difference between a repair that holds and one that reopens in the next freeze-thaw cycle. Whether it’s plugging an active pipe leak in a treatment plant, plugging utility pipe penetrations in a tunnel wall, plugging active leak points in a basement wall, or injecting a moving joint in a parking structure, the right product stops water once and keeps it stopped.

Frequently Asked Questions

Que : What's the difference between hydrophobic and hydrophilic polyurethane foam? Ans : Hydrophobic foams like Rigid Foam and Flex Foam repel water once cured, making them well suited to structures that dry out between exposures. Hydrophilic foam like Hydro Foam remains flexible and effective even in continuously wet or submerged conditions, since it's designed to work with persistent moisture rather than against it. Que : How fast do these products actually stop a leak? Ans : It depends on the product. CEM290-H sets in as little as 45 seconds by hand, while the polyurethane injection foams begin reacting within 35 to 40 seconds of contact with water and reach a tack-free state within 3 to 5 minutes. Que : Can Chem-Crete Dry Oakum be used on its own, without a polyurethane resin? Ans : No. Dry Oakum is designed to be used alongside Flex Foam, Hydro Foam, or the Pipe Plug system. It provides the fiber structure the resin saturates and expands into, rather than functioning as a standalone sealant. Que : Is Rigid Foam CCC530 suitable for continuously wet environments? Ans : Not ideally. Rigid Foam is hydrophobic and works best for dead, non-moving cracks under gushing or high-pressure water. For a crack in a continuously moist or submerged setting, Hydro Foam's hydrophilic chemistry is the better fit. Que : Do these products work on cracks underwater, or only above the waterline? Ans : Several do. CEM290-R and CEM290-H both set underwater by hand, and Rigid Foam, Flex Foam, and Hydro Foam are all listed as suitable for underwater applications when injected under the right conditions.

Epoxies

Some concrete problems can't be solved with a coating alone. A crack that's actively letting water through, an anchor bolt that has to hold real structural load, a manhole under constant chemical attack from sewer gas- all of these need a chemistry built for the specific job, not a general-purpose fix. That's what International Chem-Crete's Epoxies line is built around: a full family of epoxy systems, each engineered for a distinct application, from anchoring and doweling to gel repairs, coatings, injections, mortars, and primers.

Sealing Concrete Crack Problems Before They Spread

A crack rarely stays the size it started at. Left alone, it widens under traffic load, thermal stress, and freeze-thaw cycles, lets in water and chlorides, and eventually threatens the reinforcing steel underneath. Chem-Crete's epoxy injection range exists to stop that process at the source. Products like CHEM-INJECT XLV®, CHEM-INJECT 100, CHEM-INJECT R and CHEM-VOID cover everything from ultra-low viscosity resin built to penetrate hairline fractures to wider, low-exotherm systems designed for larger voids and cracks. Sealing concrete crack damage with an injected epoxy, rather than a surface patch, means the repair works from the inside of the crack outward, restoring structural continuity instead of just hiding the problem. With pot lives ranging from 20 to 60 minutes and elongation rates tuned to different crack movement profiles, there's a specific injection system for a hairline crack in a parking structure and a different one for a wide structural crack in a bridge deck.

Repairing Active Sewer Manhole and Pipe Systems

Sewer environments are some of the most chemically aggressive concrete faces anywhere. Hydrogen sulfide gas condenses on manhole walls and converts into sulfuric acid, and that acid eats away at concrete and mortar joints until the structure starts to fail. CHEM-SEWER, from Chem-Crete's Gel Epoxies range, is built specifically for this problem: a two-component, hydrophobic epoxy gel that cures underwater or above it, resists sulfuric acid and methanol, and bonds tightly enough to structurally repair the walls and joints before infiltration and seepage set in. Repairing an active sewer manhole with CHEM-SEWER is typically the first stage of a complete restoration system, applied by trowel to rebuild an impermeable structural layer, then finished with an acid-resistant coating like CHEM-NOVOLAC for long-term chemical protection. The same chemistry extends to patching an active sewer pipe, where CHEM-SEWER's super-wetting bond strength and resistance to hydrogen sulfide byproducts make it a reliable fix in pipe and canal repairs across sewage plants, stormwater systems, and industrial wastewater facilities.

A Product for Every Structural Application

Beyond cracks and sewer systems, Chem-Crete's Epoxies line covers the full range of concrete and steel connection work:
  • Anchoring & Doweling: CHEM-ANCHOR and CHEM-DOWEL 2 set rebar, dowels, and structural fasteners into concrete with high-strength epoxy adhesive.
  • Coatings & Linings: A ten-product range including CHEM-FLOOR, CHEM-HCR, and CHEM-NOVOLAC, covering everything from high-gloss industrial floors to high chemical resistance linings for tanks and containment areas.
  • Mortars: CHEM-MORTAR 2, CHEM-KIT®, and CHEM-REPAIR 510 provide solvent-free epoxy binders and repair mortars for structural patching, anchoring, and grouting.
  • Primers: Purpose-built epoxy primers that prepare concrete surfaces for coatings, linings, and overlays to bond properly on the first application.

Choosing the Right Epoxy System

For contractors, engineers, and municipalities working on infrastructure that has to hold up under real chemical and structural stress, choosing the wrong epoxy system shows up fast: a crack that reopens, a coating that fails against acid exposure, an anchor that pulls loose under load. International Chem-Crete's Epoxies range is organized specifically so the right product is easy to find and match to the job, whether it’s sealing a concrete crack before it spreads or repairing a sewer structure that's already under chemical attack.

Frequently Asked Questions

Que : How do I know which injection epoxy to use for sealing a concrete crack? Ans : It depends on crack width and movement. Low-viscosity products like CHEM-INJECT XLV® are built for hairline fractures, while CHEM-VOID and CHEM-INJECT 100 handle wider cracks and voids with longer pot lives for larger repair jobs. Que : Why does CHEM-SEWER work specifically in sewer manhole and pipe applications? Ans : CHEM-SEWER resists sulfuric acid and methanol, the byproducts of hydrogen sulfide gas that typically deteriorate manhole and pipe concrete, while its super-wetting quality gives it strong adhesion to wet and dry substrates alike. Que : Can CHEM-SEWER be used on its own, or does it need a follow-up coating? Ans : CHEM-SEWER structurally repairs walls and joints on its own, but for complete chemical protection in a manhole restoration system, it's typically followed by an acid-resistant coating like CHEM-NOVOLAC. Que : What's the difference between the Coatings & Linings range and the Mortars range? Ans : Coatings & Linings products like CHEM-FLOOR and CHEM-HCR are applied as thin protective layers over existing concrete surfaces. Mortars like CHEM-REPAIR 510 and CHEM-MORTAR 2 are used to rebuild damaged sections of concrete, restoring structural material rather than just protecting the surface. Que : Do these epoxy systems require special surface preparation before application? Ans : Most do. Surfaces should generally be sound, clean, and free of oil, grease, and laitance before application, and Chem-Crete's epoxy primers are specifically formulated to prepare concrete so coatings and linings bond properly on the first application.

Concrete Repair

A damaged section of concrete rarely waits for a convenient repair window. A pothole on an active runway, a spalled highway lane, a cracked loading dock floor; all of these have to be fixed and put back into service fast, without sacrificing the strength the structure needs to hold up for years afterward. International Chem-Crete's Concrete Repair line is built around that exact demand: a full range of fast-setting concrete repair mortars, structural shotcrete systems, and bonding agents engineered to get concrete back in service quickly and keep it there.

Fast Setting Concrete Repair for Every Depth

Not every repair is the same size. Chem-Crete's Super Concrete Mortar family covers the full range of patch depths with one-component, rapid strength-gaining mortars that only need water added on site. CEM140 is formulated for thin-set repairs under 1 inch deep, while CEM150 handles deeper patches starting at 1 inch. For repairs that go deeper still, CEM120H is purpose-built as a fast patch cementitious mortar for full-depth concrete repair, restoring structural sections rather than just resurfacing them. Rounding out the family, CEM210 and CEM220 are polymer-modified repair mortars formulated for floor repair and high-build patching, and CEM260 is a cementitious self-leveling floor topping for large, flat repair areas. Each product in this concrete repair family is designed to gain strength quickly, so patched areas can be reopened to traffic or equipment without an extended cure-and-wait period.

Airport Pavement Repair and Highway Pavement Repair

Runways and highways can't stay closed for long, which makes cure time as critical as strength. CHEM-CRETE® CEMENTIX® CEM 20M is a cementitious powder additive engineered specifically for this problem: mixed into a standard concrete batch, it produces a workable, fast-curing concrete that reaches over 5,800 psi within two to four hours, solving the pavement closure problem that ordinary concrete repair creates. That rapid strength gain makes CEM 20M suited to airport pavement repair on active taxiways and runway sections, and to highway pavement repair where lane closures carry real cost for every extra hour. With a slump range of 3 to 5 inches for easy placement and a 25-minute working window after mixing, crews get enough time to place the material properly before it begins its rapid strength climb.

High Compressive Strength Concrete Repair for Large Structural Work

Some repairs go beyond patching a surface, requiring a full structural rebuild on vertical or overhead concrete. CHEM-SHOTCRETE® CEM296 and the CHEM-CRETE TUNNEL LINING SYSTEM are both one-component, microsilica-enhanced shotcrete mortars built for exactly that kind of high compressive strength concrete repair, reaching roughly 7,700 psi at 28 days with strong bond strength and low water absorption. Both are applied by dry spray guniting, making them practical for large vertical and overhead structural repairs where traditional formwork isn't feasible, from tunnel linings to bridge substructures. For repairs that call for a liquid bonding solution rather than a sprayed mortar, EB550 is an SBR latex bonding agent that improves the bond between new repair material and existing concrete, a critical step for making sure a patch stays put under real load.

Choosing the Right Repair Product for the Job

  • Thin or shallow patches: CEM140, CEM210, CEM220
  • Deep or full-depth structural patches: CEM150, CEM120H
  • Runway and highway pavement closures: CEM 20M
  • Large vertical or overhead structural rebuilds: CHEM-SHOTCRETE CEM296, Tunnel Lining System
  • Improving bond strength on any repair: EB550
For highway departments, airport authorities, and contractors managing infrastructure that has to reopen fast, matching the repair depth and timeline to the right product is what keeps a fix from becoming a repeat job.

Frequently Asked Questions

Que : What makes a concrete repair mortar "fast setting"? Ans : Fast-setting concrete repair mortars are formulated to gain usable strength within hours rather than the standard 28-day cure cycle, allowing patched areas to be reopened to traffic or equipment much sooner. Que : When is a full-depth concrete repair necessary instead of a surface patch? Ans : Full-depth concrete repair is needed when deterioration or damage extends through the full thickness of a slab or section, not just the surface. CEM120H is formulated specifically for this kind of structural-depth patching. Que : Why does airport pavement repair require a different product than a typical concrete patch? Ans : Airport pavement repair often has to reopen within hours, not days, so products like CEM 20M are engineered for very rapid compressive strength gain, solving the pavement closure problem that standard concrete repair creates. Que : Can CHEM-SHOTCRETE CEM296 be used for both vertical and overhead repairs? Ans : Yes. It's formulated for dry shotcrete application in overhead, vertical, and horizontal repairs, making it suited to structural work like tunnel linings and bridge substructures where traditional formwork isn't practical. Que : Does EB550 replace the need for a repair mortar? Ans : No. EB550 is a bonding agent, not a repair mortar. It's used alongside products like CEM140 or CEM150 to improve adhesion between new repair material and the existing concrete substrate.

Cleaners

Every coating, sealer, or repair mortar is only as good as the surface it's applied to. Oil, grease, laitance, curing compounds, or biological growth left on a concrete surface can quietly undermine adhesion, turning a properly specified product into a failed application months down the road. International Chem-Crete's Cleaners line exists to eliminate that risk, giving contractors and facility teams the right cleaning chemistry for concrete preparation, tool maintenance, and general surface sanitation, all in one category.

A Biodegradable Concrete Cleaner Built for Real Job Sites

CONCLEAN CCC060 is the workhorse of this category, and for good reason. It's a multi-purpose concrete cleaner formulated as an alkaline-based, water-soluble detergent and degreasing agent that attacks the molecular structure of greases, oils, dirt, and polymers, then emulsifies them so they rinse off easily with water. As a concrete degreaser, it's strong enough to cut through the contamination left behind by construction equipment, yet gentle enough to use on metal surfaces, vinyl floors, marble, granite, and limestone. What sets CONCLEAN CCC060 apart is its formulation. It's a biodegradable concrete cleaner that's completely non-flammable, non-fuming, and safe on skin, making it a genuinely environmentally friendly concrete cleaner for job sites where worker safety and runoff matter. It's routinely specified as the pre-treatment step before applying waterproofing coatings, sealers, and crystalline systems across power plants, warehouses, industrial facilities, and even heritage stone restoration work, anywhere a clean, contaminant-free surface is non-negotiable before the next product goes on.

An Acid-Based Option for Deeper Etching

Not every surface just needs degreasing. Some concrete needs to be etched as well as cleaned, particularly closed, dense surfaces that resist penetration from waterproofing coatings and sealers. CONCLEAN PLUS CCC070 is formulated with hydrochloric acid, specialty penetrants, and fume arrestors to minimize acid vapor during application, giving contractors a rapid-acting cleaner and light-etching agent in one product. It's used to remove rust stains, mill scale, and biomass from brick and concrete, and to open up a closed surface so coatings and sealers can properly penetrate and bond.

Solvent and Surface Maintenance Products

Beyond concrete preparation, this category also covers the practical, everyday maintenance side of a job site. CHEM-CRETE BLENDED SOLVENT is used to clean tools and equipment of uncured epoxy resin immediately after use, a step that protects expensive mixing and application equipment across nearly every epoxy product in the Chem-Crete line. And for general facility and surface sanitation beyond the concrete itself, the IPA Micro-Clean family, available as a wipe, a fogging solution, and a liquid concentrate, provides a high-pH, isopropanol-based cleaner for reducing cross-contamination on non-porous surfaces in transit centers, airports, schools, and public facilities.

Choosing the Right Cleaner for the Job

  • General concrete degreasing and pre-treatment: CONCLEAN CCC060
  • Etching dense or closed concrete surfaces: CONCLEAN PLUS CCC070
  • Cleaning tools after epoxy application: CHEM-CRETE BLENDED SOLVENT
  • General facility and surface sanitation: IPA Micro-Clean Wipe, Fog, or Liquid
For contractors, engineers, and facility managers working across highway, municipal, industrial, and heritage projects, starting with the right cleaner isn't a minor step; it's what determines whether the coating or repair applied afterward actually holds.

Frequently Asked Questions

Que : What makes CONCLEAN CCC060 an environmentally friendly concrete cleaner? Ans : CONCLEAN CCC060 is biodegradable, water-soluble, non-flammable, non-fuming, and safe on skin, making it suitable for job sites where minimizing chemical exposure and runoff impact matters. Que : When should I use a concrete degreaser instead of an acid-based cleaner? Ans : A concrete degreaser like CONCLEAN CCC060 is the right choice for removing oil, grease, and dirt without altering the concrete surface. An acid-based cleaner like CONCLEAN PLUS CCC070 is better suited when the surface also needs light etching to open it up for coatings or sealers. Que : Can CONCLEAN CCC060 be used on surfaces other than concrete? Ans : Yes. As a multi-purpose concrete cleaner, it's also formulated to clean metal surfaces, vinyl floors, marble, granite, and limestone, making it a versatile choice across mixed-material job sites. Que : Is CHEM-CRETE BLENDED SOLVENT meant for cleaning concrete surfaces? Ans : No. It's formulated specifically for cleaning uncured epoxy resin from tools and equipment, not for concrete surface preparation. CONCLEAN CCC060 or CONCLEAN PLUS CCC070 are the right choice for that step. Que : Are the IPA Micro-Clean products used for concrete cleaning? Ans : Not directly. The IPA Micro-Clean line is formulated as a general-purpose surface and air sanitation system for non-porous surfaces in facilities like transit centers, airports, and schools, rather than as a concrete surface preparation cleaner.
