Brushbond TGP* crystalline capillary waterproofi ng system contains proprietary blend of portland cement, quartz aggregate and special chemicals. In the presence of moisture, the active chemicals in Brushbond TGP* crystalline waterproofing system penetrates concrete and react chemically with free lime to produce insoluble crystals. This crystalline growth reduces porosity by blocking capillaries and fi lling hairline non structural cracks ( upto 0.25mm wide) caused by shrinkage or expansion.
Unlike metallic and membrane types of waterproofing which only form a surface barrier, Brushbond TGP* crystalline waterproofing system, in the presence of water, continues producing
crystals and lasting imperviousness to water.
