Description of concrete pvc water stop :
concrete pvc water stop being embedded in the concrete joints, acts as a continuous watertight diaphragm 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.
Features of concrete pvc water stop :
1.High tensile strength.
2.Superior elongation capability.
3.Excellent inherent elasticity and impermeability
4.High resistance to acids, ozone, seawater even diesel oil.
5.Extremely alkalis, chlorinated water and other waterborne chemicals resistant.
6.Not susceptible to fatigue deterioration as with metal or rubber.
7.High quality meet even exceed the industrials standard.
8.Never discolor concrete.
9.No electrolytic action with surrounding metals.
10.Capable to withstand hydrostatic pressure.
11.Heat weldable in conjunction with electric splicing irons.
12.Withstand the expansion and contraction movement of the joints.
13.Capable to taking care of any deflection or displacement arising caused by temperature changing or differential settlement of foundation.
14.Supplied in coils for easy handling with high flexibility.
15.Easy to install by tethering the outer flanges of the PVC waterstop to adjacent a reinforcing bars.
