Hydrophilic & Hygroscopic Moisture & Vapor Blocker up to 16 Lbs per 1000 ft² per 24 Hours

CHEM-CRETE SOFIX CCC700 is a unique one of a kind water-based crystallization product specifically designed to permanently block moisture and vapor transmission in concrete or masonry structures up to 16 Lbs / 1000ft2 / 24 Hours*. Application of the CHEM-CRETE SOFIX CCC700 system blocks moisture and vapor movement through concrete and masonry substrates within 24 hours. The CHEM-CRETE SOFIX CCC700 can be easily applied by spraying or rolling. CHEM-CRETE SOFIX CCC700 is designed to be applied to concrete substrates that are 7 days or older. The CHEM-CRETE SOFIX CCC700 is formulated to enhance deep penetration into the concrete substrate through capillary action. The product components migrate deep into the concrete substrate to form a hygroscopic and hydrophilic crystalline material which permanently blocks the concrete and masonry substrate pores. Even under the influence of constant hydrostatic pressure, the crystallization continues to fill and block the migration of moisture through the concrete substrate. The crystallization activity of the CHEM-CRETE SOFIX CCC700 system is continuous while moisture is present. The product becomes inactive during dry conditions and is fully reactivated when moisture or moisture vapor are present. The unique “reactivation” is the key in providing permanent waterproofing protection for any concrete or masonry substrate. CHEM-CRETE SOFIX CCC700 is an odorless, colorless, clear liquid with very low viscosity that allows it to penetrate deeply into a concrete substrate or other masonry products. The product protects preserves and waterproofs without any surface film formation or color change.

Applicable Standards: CHEM-CRETE SOFIX CCC700 meets or exceeds:

  • ASTM C666     Freeze thaw testing.
  • ASTM D3359: 28% increase in epoxy adhesion or surface coating.
  • Weathering Test ASTM G23: Ultraviolet light and water spray exposure had no adverse effect on CHEM-CRETE SOFIX CCC700 treated samples.
  • NCHP#244 “Soak Test” Rev.




Methods of Application: By spraying, rolling or brushing.


Tools Needed: CHEM-CRETE SOFIX CCC700 can be applied using one or more of the following:

  • Low pressure sprayer.
  • Paint roller or paint brush.
  • Bristle broom.
  • Squeegee.


Surface Preparation: Surface must be clean, and free of paint, sealer, oil, adhesive, curing compound, form release agent and/or anything that will not allow CHEM-CRETE SOFIX CCC700 to penetrate the substrate.  Areas which require cleaning must be cleaned by scrubbing, pressure washing or other methods to remove any surface dust, dirt or other contaminants. CHEM-CRETE SOFIX CCC700 may be applied to damp surfaces as long as no standing water or puddles are present. Heavy contaminated areas must be cleaned using Chem-Crete CONCLEAN CCC060 biodegradable concrete cleaner and a pressure washer to help remove deeply penetrated areas.

If application surface is a concrete floor which will receive a resilient flooring, then the guidelines published in current ASTM F710 should be followed by the applicator.

Coverage: Two coats, approximately 200 ft2 per gallon per coat (4.91 m2 per liter per coat) of CHEM-CRETE SOFIX CCC700.  Coverage depends on porosity of the concrete.


Limitations: Do not apply CHEM-CRETE SOFIX CCC700 in the following cases:

  • When temperature falls below 40°F (5°C).
  • To areas previously treated with curing or sealing agents unless these coatings have been removed by chemical or mechanical means.
  • Do not use or allow it to come into contact with aluminum or glass. Crystallization will occur on surface. If contact occurs, immediately wash off with water.
  • Do not use on glazed tiles or glazed bricks. Crystallization will occur on surface. If contact occurs, immediately wash off with water.

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


Eighteen months shelf life when stored in cool, dry place in unopened container. Always agitate or stir the bucket or drum before using. DO NOT ALLOW PRODUCT TO FREEZE. Repeated freezing & thawing might cause damage for 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.  Any direct contact with skin, eyes, etc. should be washed thoroughly with clean running water and soap.

Always wear protective goggles and gloves. In case of eye contact, flush for 15 minutes with clean water. KEEP OUT OF REACH OF CHILDREN.
