High-Grade ECB Geomembrane

Railway tunnels, underground subways and large water conservancy projects face long-term water seepage, low-temperature cracking and chemical erosion troubles. Our High-Grade ECB Geomembrane belongs to premium durable membranes, a top-tier thermoplastic Waterproof Membrane blended with ethylene polymer and oil resin, far more stable than ordinary PE geomembrane for long-term tunnel and underground anti-seepage engineering. This industrial geomembrane meets GB18173.1-2012 and TB/T 3360.1-2014 standards, with tensile strength ≥17MPa and elongation up to 580%. As reliable durable membranes, it stays crack-free at -35℃ and maintains stable performance after long-term aging. Excellent tear resistance avoids damage during tunnel construction, and it passes the strict 0.3MPa 30-minute water impermeability test without leakage. It also features low asphalt extract content to fit high-standard railway tunnel projects. This flexible Waterproof Membrane supports customized specs: 1.0–2.0mm thi…
