Brushbond TGP

Brushbond TGP crystalline capillary waterproofing system is a series of products containing proprietary blends of Portland cement, quatz aggregate and special chemicals. In the presence of moisture, the active chemical in Brushbond TGP penetrate concrete and reacts chemically with tree lime to produce insoluble crystals. This crystalline growth reduces porosity by blocking cappilaries and filling hairline non structural cracks (up to 0.25 mm wide) caused by shrinkage or expansion. Unlike metalic and membrane types of waterproofing, which only form a surface barrier, Brushbond TGP, in the presence of water, continues producing crystals and a lasting imperviousness to water.
