When added to concrete, active chemicals create a reaction that causes insoluble crystals to form, filling pores and capillaries found in concrete, and thus preventing the movement of water. Remains permanently active and withstands positive and negative hydrostatic pressure equally well. Suitable for waterproofing of foundations, basements, water tanks, sewage and wastewater treatment tanks, swimming pools, etc.
