EVA Construction Joint Waterstop

Alpine tunnels and cold-region reservoirs suffer joint cracking & leakage under low temperature and concrete expansion. Our EVA Construction Joint Waterstop belongs to reliable durable membranes, a cold-resistant sealing accessory matched with geomembrane to build full underground Waterproof Membrane anti-seepage systems. This geomembrane supporting accessory meets standard specs: tensile strength ≥14MPa and 600% high elongation. As durable membranes resistant to -40℃ frangibility, it reaches 60kN/m tear strength to buffer concrete extrusion. Buried across construction joints, it forms permanent leakproof barriers and keeps corrosion-proof for long-term hydraulic 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 EVA waterstop accepts bulk wholesale & OEM. As a China direct manufacturer, we provide full test reports and embedded c…
