EVA Geomembrane

Engineering Shielded by Innovation, Durability Engineered to Last

Product Overview

EVA Geomembrane (Ethylene-Vinyl Acetate Geomembrane) is a high-performance flexible impermeable liner manufactured from premium EVA resin through specialized processes. Combining exceptional low-temperature resistance, high elongation, puncture resistance, and environmental adaptability, it is designed to address critical impermeability challenges in extreme conditions. Ideal as the primary barrier for tunnels, landfills, artificial lakes, and other demanding engineering applications.

Key Advantages

1. Ultra-Low Temperature Flexibility

   • Withstands temperatures down to -70°C, maintaining elasticity in freezing environments without brittleness. Perfect for high-altitude, permafrost, and arctic regions.

2. Superior Elongation & Puncture Resistance

   • Elongation at break ≥600%, accommodating ground settlement and deformation;

   • Outstanding puncture strength resists damage from sharp objects (e.g., rocks, roots).

3. Long-Term Weathering & Anti-Aging

   • UV and oxidation inhibitors extend service life to ≥30 years under harsh exposure (sunlight, rain, snow).

4. Excellent Chemical Stability

   • Resists acids, alkalis, salts, oils, and most organic solvents. Widely used in corrosive environments (chemical containment, leachate collection).

5. Eco-Safe Compliance

   • Non-toxic raw materials comply with GB/T 17643-2011 (Chinese National Standard), suitable for potable water reservoirs and aquaculture.

Applications

✅ Underground Works: Metro tunnels, utility tunnels, foundation pit lining
✅ Environmental Protection: Landfills, hazardous waste facilities, wastewater lagoons
