CWC®SMARTCRYSTAL Crystalline waterproofing admixture protects and waterproofs concrete structures by crystallization. The active chemicals react with moisture and by product of cement hydrate in the concrete resulting in crystalline formation within the pores and capillary tracts of concrete thus waterproofing the structure against penetration of water and other liquids from any direction CWC®SMARTCRYSTAL gives strong and lasting waterproofing protection from harsh environmental conditions.
CWC®SMARTCRYSTAL conforms to IS 2645-2003 and ACI 212.3R-10
- Mixed with concrete at the time of batching
- Sealing cracks or voids up to 0.5mm by crystal formation
- Protects concrete exposed to harsh conditions
- An integral system application
- Crystals are insoluble in water therefore voids are sealed permanently.
- Non-toxic and non-hazardous for drinking water and aquatic /marine life.
- No side effect on fresh as well as hardened concrete.
- Compatible with all types of concrete plasticizers /superplasticizers.
- Wear hand gloves, safety shoes and safety goggles while using and handling the product.
- In case eyes or mouth are affected wash with plenty of clean water and seek medical treatment immediately.
Before use, refer to the Material Safety Data Sheet.
