PVC WATERSTOP are manufactured by melting and shaping mixtures that obtained from Polyvinylchloride (PVC) resin, stabilizer, plasticizer and antioxidant dyestuff in suitable temperature and pressure in extruders. It is confirmed according to TS 3078, ASTM, DIN, BS, DSI norms. PVC WATERSTOP are used for providing water impermeability in expansion - contraction (structure) joints seen in concrete structures exposed to high and low water pressure and for preventing vibrations and deformations that would appear in concrete blocks.
