Hydrophilic and Hygroscopic Water Vapor and Moisture Blocker for transmission rates up to 18 Lbs per 1000 ft², per 24 Hours

CHEM-CRETE® SOFIX® CCC® 700 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 18 Lbs per 1000 ft2, per 24 hours (ASTM F1869).


SOFIX CCC 700 produces water-insoluble, hydrophilic and hygroscopic 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 hydrophilic crystals absorb the vapor and moisture, rapidly swelling and blocking the pores and capillaries. The hygroscopic crystals grow in the presence of vapor and moisture providing additional transmission blocking performance. Over time, hygroscopic crystals will continue to grow, providing ever-increasing transmission-blocking performance.


This product is designed to perform in applications that may be subject to continuous exposure to vapor and moisture. The product becomes inactive during dry conditions and is fully reactivated when vapor or moisture are present. The unique reactivation is the key in reducing vapor and moisture transmission.


The very low viscosity of SOFIX CCC 700 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

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 700 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 700 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.
