PVC Construction Joint Waterstop

High water seepage occurs at concrete expansion joints of tunnels, reservoirs and basements, caused by thermal expansion and long-term corrosion. Our PVC Construction Joint Waterstop belongs to reliable durable membranes, an elastic sealing accessory matched with geomembrane to build a complete underground Waterproof Membrane anti-seepage system. This geomembrane matching accessory meets standard indexes: tensile strength ≥14MPa and elongation over 300%. As durable membranes resistant to -25℃ low temperature, it reaches 20kN/m tear strength to resist concrete extrusion. Buried across construction joints, it forms a continuous leakproof barrier and stays corrosion-proof for long-term underground projects. This flexible Waterproof Membrane accessory supports custom sizes: 4.0–8.0mm thickness, 200–350mm width, 10m rolls. Widely paired with geomembrane for subways, dams and sewage tanks, this PVC waterstop supports bulk wholesale & OEM. As a Chinese direct manufacturer, we supply…
