Offers rubber sealant and water sealing solutions. The PVC [Polyvinyl chloride] Water Stop Seals are designed for use in concrete joints subjected to hydrostatic pressures. After being embedded in concrete, PVC water stops fill up the joints to form a continuous watertight diaphragm that prevents the passage of fluid. The water stop must be designed and installed properly to accommodate joint expansions, contraction and lateral & transverse movements. In addition to this consideration the water stop must be compatible with the concrete system and the liquids and chemicals to be contained or controlled. The PVC Water Stop Seals are tied to the steel frame works or small eyelet by means of small wires, certain metal clamps made to grip the water stop seal to keep it in proper position.
