Hydrophilic Water Vapor and Moisture Blocker for Transmission Rates up to 12 Lbs per 1000 ft², per 24 Hours

CHEM-CRETE® SOFIX® CCC® 100 is a unique, water-based blend of catalyzed chemicals that significantly reduces water vapor and moisture transmission through concrete and masonry structures.  It is suitable for transmission rates up to 12 Lbs per 1000 ft2, per 24 hours (ASTM F1869).


SOFIX CCC 100 produces water-insoluble, hydrophilic crystals within the concrete capillaries, voids and pores. The affinity of the crystals to vapor and moisture is extremely high. In the presence of vapor and moisture, the crystals absorb the vapor and moisture, rapidly swelling and blocking the pores and capillaries, resulting in reduced vapor and moisture transmission.


The very low viscosity of SOFIX CCC 100 allows it to penetrate deeply into the substrate. The product protects, preserves and waterproofs without any surface film formation or color change. It will not interfere, and may improve, the adhesion properties of concrete coatings, paints and sealers. Treatable substrates include concrete, cementitious mortars and plasters, limestone.


Areas of application:

  • Slabs and foundations
  • Pools
  • Walls
  • Tunnels
  • Pits
  • Reservoirs

  • Concrete floor coverings (carpet, wood, vinyl, tile, etc.)
  • Concrete coatings (epoxy, polyurethane, polyurea, etc.)
  • Concrete sealers and stains
  • Concrete wall and ceiling paints and architectural coatings
  • Abatement of fungus, mold, mildew, algae and bacteria


  • Single-component, ready-to-use and easily applied
  • Low viscosity and deep penetration
  • No VOC, environmentally-safe, non-toxic and odorless

  • Increases the service life of concrete coatings (protects against debonding, blistering, bubbling and adhesion failures)
  • Increases the service life of concrete paints, stains and sealers
  • Increases adhesion of coatings, paints and sealers
  • Reduces or prevents fungus, mold, mildew, algae and bacteria growth on concrete floors, walls and under floor coverings (carpet, wood, vinyl, etc.)
  • Becomes an integral part of treated substrate
  • Reduces freeze-thaw damage
  • Reduces or eliminates silicate dusting
  • UV stable
  • Can be applied to fresh or existing concrete

  • ASTM G23: Standard Practice for Operating Light-Exposure Apparatus (Carbon-Arc Type) With and Without Water for Exposure of Nonmetalic Materials


Methods of Application: Spray, roll or brush.


Apply using:

–   Low-pressure sprayer –   Paint brush or roller
–   Bristle broom –   Squeegee


Surface Preparation: Surface must be clean, free of surface efflorescence, paint, sealer, oil, adhesive, curing compound, form release agent and/or anything that will impede SOFIX CCC 100 penetration into the substrate.


Recommended cleaning methods include compressed air, pressure washing, scrubbing or other methods to remove surface dust, dirt or other contaminants.


Heavily contaminated areas must be cleaned using biodegradable concrete cleaners (CHEM-CRETE CONCLEAN CCC060, recommended) and a pressure washer to remove deeply penetrating contaminants.


SOFIX CCC 100 may be applied to damp surfaces free from standing water.


If installing resilient flooring, follow ASTM F710 (Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring)


Coverage: Two coats required, 200 ft2 per gallon, per coat (4.91 m2 per liter, per coat).  Excessively porous substrates may require additional material. Apply with an even, uniform spreading rate.


Limitations: Do not apply under the following conditions:

  • Temperature below 40ºF (5°C)


Precautions: During application, do not allow product to come in contact with metal or glass. If contact occurs, immediately wash contacted area with water to prevent crystal formation.


Cleaning: Clean all equipment and tools with clean water immediately after use.


Two-year shelf life when stored in its original, unopened container, in a cool, dry place. Always agitate the product before using. DO NOT ALLOW PRODUCT TO FREEZE. Repeated freezing and thawing may cause damage to the product.


As with all construction chemical products, adequate precautions and care must be taken during usage and storage.  Avoid direct contact with foodstuff, eyes, skin and mouth.  Contacted areas should be washed thoroughly with clean running water and soap.

Always wear protective goggles and gloves. In case of eye contact, flush for fifteen minutes with warm water. If eye irritation persists, seek medical attention. In case of ingestion or swallowing, drink two glasses of clean water and seek medical attention. KEEP OUT OF REACH OF CHILDREN.
