Reinforced Polymer Membrane for Roof Waterproofing

Tunnels, underground foundations and hydraulic reservoirs constantly face leakage, low-temperature cracking and chemical erosion caused by ground deformation. Our EVA waterproof board belongs to top-tier durable membranes, a premium Waterproof Membrane co-extruded from EVA copolymer and high-molecular PE, delivering better cold flexibility than rigid HDPE geomembrane for underground and roof anti-seepage projects. This industrial geomembrane meets GB18173.1 and TB/T3360.1 standards with reliable mechanical performance: tensile strength ≥18MPa and elongation over 650%, allowing flexible deformation without breakage under foundation shift. As long-lasting durable membranes, it stays crack-free at -35℃, resists acid, alkali and salt corrosion, and achieves zero leakage under 0.3MPa water pressure for 24h. This high-barrier Waterproof Membrane features hot-weldable laps for fast, seamless on-site installation. Custom geomembrane sizes are available: 1.2/1.5/1.8mm thickness, 2–4m width,…
