PVC water stops are used 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 passing of fluid. The water stop must be designed and installed properly to accommodate joint expansions, contraction and lateral & transverse movements. In addition to these considerations the water stop must be compatible with the concrete system and the liquids and chemicals to be contained or controlled.
Its basic advantage is in its time of fixing. It works as a sealant and it is fixed on predetermined place while concrete slab is laid. It is easy to installing and easy to weld at site and at required angle & shape.
