High-density polyethylene geomembrane is an advanced waterproof material manufactured using triple co-extrusion technology from Italian equipment. Composed of 97.5% HDPE and 2.5% carbon black with anti-aging additives, it meets national standards comparable to US specifications.

• Superior Anti-Seepage: Permeability coefficient ≤1.0×10⁻¹³ g·cm/(cm²·s·Pa)
• Chemical Resistance: Excellent stability against acids, alkalis, salts, oils, and alcohols
• Root Penetration Resistance: Excellent puncture resistance prevents plant root damage
• UV & Aging Protection: 85°C oven aging maintains 55% standard OIT and 80% high pressure OIT after 90 days
• High Mechanical Strength: Meets GRI-GM13 standards for tensile, tear, and puncture resistance
• Environmental Safety: Non-toxic formulation suitable for drinking water ponds and aquaculture
• Cost Efficiency: Lower cost compared to traditional waterproof materials
• Rapid Installation: Flexible laying methods accommodate various construction requirements

Available Dimensions: Thickness 0.30mm-3.00mm, Width 1m-9m, Roll Length 30m-100m (custom orders accepted)

• Landfills, sewage treatment, and waste disposal facilities
• River banks, lake dams, tailings dams, and reservoirs
• Subway tunnels, basements, and underground structures
• Roadbed foundations and brine seepage control
• Aquaculture ponds for both seawater and freshwater species
• Highway and railway waterproofing layers
• Roofing seepage prevention systems
