PVC water stopper is being used at my project and we are all very satisfied with it. besides it we are also using water bars in concrete joints.
Considering the practical workmanship in fixing water bars , Elastomeric swellable water bars are best than PVC
There are various types of waterstops for diffferent uses.
PVC waterstop, as the most common watertight type, features high tensile strength, elongation capability and high resistance to acids, ozone, alkalis, diesel oil, chlorinated water and other chemical liquids. Meanwhile, they will not discolor the concrete or support even produce electrolytic action with surrounding reinforcing steels.
waterstop is a hydrophobic water sealing products capable to withstand high water pressure and absorb high movements of concrete joints. Generally, SBR, neoprene rubber and natural rubber are the main materials for manufacture of rubber waterstops
One particular material waterstop suits one particular condition.
