CAPISEALTM is a deep penetrative, reactive, cementitious crystalllary waterproofing coating system. It contains proprietary blend of portland cement, quartz aggregate and special additives. In the presence of moisture, the active chemicals in CAPISEAL crystalrproofing system penetrates concrete and react chemically with free lime to produce water-insoluble nano-crystals. This crystalan>growth reduces porosity by blocking capillaries and filling hairstructural cracks caused by shrinkage or expansion. Unlike metallic and membrane types of waterproofing which only form a surface barrier, CAPISEAL crystalan>waterproofing system, in the presence of water, continues producing crystals and lasting imperviousness to water.
