Blockout Crystor

Crystalline Capillary Waterproofer

Product Description

BLOCKOUT CRYSTOR is a crystalline waterproofing formulation of selected blends of cement, very fine treated silica sand, and various proprietary active chemicals providing a lasting imperviousness to water. BLOCKOUT CRYSTOR is a unique chemical treatment for the waterproofing and protection of concrete. In the presence of moisture, the active chemicals in BLOCKOUT CRYSTOR penetrate concrete and react chemically with free lime to produce insoluble crystals. This crystalline growth reduces porosity by blocking capillaries and filling hairline nonstructural cracks caused by shrinkage or expansion.
