Permastop is a non-toxic unique chemical treatment for the waterproofing, protection and repair of concrete. It consists of Portland cement, graded aggregates and active proprietary chemicals; it is applied as a cementitious slurry to a cement surface that is pre-saturated with water. The active chemicals diffuse into the substrate and react with moisture and the constituents of hardened concrete to cause a catalytic reaction. This reaction generates a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete, as well as cracks, permanently sealing the concrete and preventing the penetration of water and other liquids from any direction, even under high hydrostatic pressure. Even after the concrete has cured, Permastop remains dormant in the concrete and will reactivate in the presence of moisture to seal capillary tracts and hairline cracks.
