Buried PVC waterstop is a flexible waterproof strip made of polyvinyl chloride (PVC) resin and special additives by extrusion molding. It is pre-embedded in the middle position of concrete construction joints and deformation joints. After concrete pouring, it integrates with concrete. When the joint deforms or water pressure occurs, the waterstop can bear deformation and block seepage channels, providing long-term waterproof sealing for concrete structures.
It has excellent tensile strength, elongation, tear resistance, low-temperature flexibility and aging resistance. It is resistant to corrosion from common alkalis in concrete. Widely used in tunnels, subways, basements, reservoirs, culverts, sewage treatment plants and other hydraulic and underground projects.
Construction reminder: Ensure the waterstop is placed at the center of the joint; avoid sharp steel bars piercing the belt during concrete casting.
