POLYCOTE CWP crystalline capillary waterproofing system contains properly blend of Portland cement, quartz aggregate and special chemicals. In the presence of moisture, the active chemicals in POLYCOTE CWP crystalline waterproofing system penetrates 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. Unlike metallic and membrane types of waterproofing which only form a surface barrier, POLYCOTE CWP crystalline waterproofing system, in the presence of water, continues producing crystals and lasting imperviousness to water.
