High-Performance Construction Waterproof Sheet

Mountain tunnels, underground foundations and hydraulic facilities often face cracking, corrosion and persistent leakage issues caused by ground deformation and extreme low temperatures. Our EVA waterproof board stands out among reliable durable membranes, a premium Waterproof Membrane engineered to solve long-term anti-seepage troubles for global infrastructure, with better low-temperature flexibility than rigid HDPE geomembrane. Manufactured from high-molecular EVA copolymer, this geomembrane boasts excellent mechanical indicators: tensile strength reaches 18MPa and elongation hits 650%, which lets it stretch freely to fit foundation movement without rupture. As one of the most practical durable membranes, it stays intact at -35℃ and resists acid, alkali and salt erosion for decades. This barrier-type Waterproof Membrane achieves zero water seepage under 0.3MPa pressure for 24 hours, and hot-weldable joints simplify field installation greatly. We provide customizable geomembrane w…
