Brushbond Crystal Plus is a crystalline capillary waterproofing system, a blend of proprietary Portland cements, aggregates, and specialized chemicals. In the presence of moisture, the active chemical additives penetrate concrete and react chemically with free lime to produce insoluble crystals. This crystalline growth reduces concrete porosity by blocking capillaries and filling hairline cracks caused by shrinkage or expansion. Unlike membrane waterproofing types that only provide a surface barrier, Brushbond Crystal Plus continues to produce crystals in the presence of water, providing long-lasting impermeability.
