Product Overview
Our HDPE Geomembrane is a robust, engineered solution designed specifically for the harsh demands of mining waste management. Ideal for tailings ponds, heap leach pads, and waste rock containment, this geomembrane provides superior chemical resistance, puncture protection, and long-term durability to prevent environmental contamination and comply with stringent industry regulations.
Key Features
Unmatched Chemical Resistance
Resists corrosive acids, alkalis, heavy metals, and leaching agents commonly found in mining waste (e.g., cyanide, sulfuric acid).
Maintains integrity even when exposed to aggressive pH levels (1–14).
Extreme Durability
Reinforced with high tensile strength (≥30 MPa) to withstand heavy loads, sharp rock abrasion, and mechanical stress.
UV-stabilized with carbon black additives for prolonged outdoor exposure without degradation.
Zero Permeability Guarantee
Ultra-low permeability coefficient (<1×10⁻¹³ cm/s) ensures complete containment of toxic liquids and slurries.
Heat-fused seams create leak-proof barriers, validated by spark testing or air lance inspection.
Environmental Compliance
Meets EPA, MSHA, and global mining waste containment standards.
Prevents groundwater contamination and protects ecosystems from hazardous leachates.
Cost-Effective Installation
Lightweight rolls (up to 8m width) enable rapid deployment over large areas, reducing downtime.
Compatible with geotextiles or clay layers for hybrid liner systems.
Technical Specifications
Material: High-Density Polyethylene (HDPE) with 2.5–3.5% carbon black

Elongation at Break: ≥700%
Temperature Tolerance: -60°C to +100°C
Certifications: ASTM GRI-GM13, ISO 9001, EPA Subtitle D, MSHA Part 48
Applications
Tailings storage facilities (TSFs) and slurry containment
Heap leach pads for mineral extraction
Waste rock dump liners and caps
Acid mine drainage (AMD) containment
Secondary containment for hazardous materials
