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.
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/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 expansion and contraction movement of 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.
Installation:
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:
- Punched flanges
- Grommets
- Hog rings or clamps

Waterstop bands are carefully packed in sturdy materials like plastic or cardboard, with clear labels showing product details and handling instructions. The packaging is sealed to keep out moisture, and each package includes a quality certificate and user instructions.
For transportation, waterstop bands are typically shipped by sea for cost efficiency, especially for large or long-distance shipments. They're stored in dry, well-ventilated areas to avoid damage from weather. Packages are made to be strong and waterproof, with extra care for urgent or special deliveries. We follow all necessary regulations to ensure safe and compliant international shipping.
