rubber waterstop strip sealing waterproof material
PVC waterstop, being embedded in the concrete joints, acts as a continuous watertight diaagm to prevent any seepage of liquids in constructions joints which are subject to hydrostatic pressure. It is designed for expansion or contraction joint; meanwhile, it can accommodate lateral and transverse movements which make it capable to suit the moving joints.
