PVC waterstop, 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.
The PVC waterstop is extruded form an elastomeric plastic material including high grade polyvinyl chloride, special resin and some chemical additives such as plasticizers and stabilizers. The high material makes PVC waterstops unsurpassed with a variety of features and benefits as shown follow.

In general, the right way of waterstop installation determines the performance in preventing waters and other waterborne chemicals. Any deflection and misalignment should be avoided - that means the best way of installation is to fix the PVC waterstop to the surrounding steel. So for easy installation, three economical methods are provided by our company as shown in the picture:
1. Advanced and Sufficient equipment More than 100 sets of most advanced equipment in our workshop ensure timely delivery time for large orders. Additional, it can ensure standardized production, which accord with international standard.
2. Experienced and skilled worker team Equipped with professional production skills and several years experience, our worker team can improve production efficiency and reduce production losses for cost reduction.
3. Multiple models for completed products We have almost all of standard bearing pad models to produce standard bearing pads, including pot bearing, laminated bearing pad, spherical bridge bearing, high damping rubber bearing and lead rubber bearings.
4. Perfect Package & Timely delivery All the products are inspected before loading, then they will be perfectly packed. Then our skilled loading team will operate the equipment for easy and fast loading.
5. Professional sales team Full knowledge of bearing pad products, good spoken and written English and excellent communication skills can offer you the best solutions to your questions. You can ask for recommendation, customized service and any other information you want from them.
