Product Description

Product Description

The PVC waterstop is a high-performance waterproofing material made from premium polyvinyl chloride (PVC) resin, combined with plasticizers, stabilizers, and other additives through an extrusion process. The PVC waterstop offers excellent elasticity, corrosion resistance, and aging resistance, forming a continuous waterproof barrier in concrete structures to effectively prevent water infiltration through construction or expansion joints. It is widely used in tunnels, basements, dams, reservoirs, and other concrete structures, serving as a critical component for ensuring waterproof safety in buildings.

The PVC waterstop can be designed in various cross-sectional shapes such as dumbbell, ribbed, or center bulb types to suit different joint types and movement requirements. During installation, the PVC waterstop bonds tightly with concrete and is connected through heat welding to ensure overall sealing performance and structural stability. Its superior chemical resistance makes it ideal for use in corrosive environments such as sewage treatment plants and chemical facilities, maintaining long-lasting waterproof performance.

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

Product Features
    *High Elasticity and Elongation: The PVC waterstop adapts to thermal expansion, contraction, and settlement of concrete structures, preventing leakage through cracks.
    *Excellent Chemical Resistance: Strong resistance to acids, alkalis, salts, oils, and other chemicals, suitable for harsh environments.
    *Aging and Ozone Resistance: Long-term use without cracking or deterioration, offering a long service life and low maintenance cost.
    *Heat-Weldable Joints: PVC waterstops can be joined by heat welding, ensuring strong and leak-proof connections.
    *Multiple Specifications Available: Customizable in width, thickness, and profile shape to meet specific project needs.
