Tailings Management Solution HDPE Smooth Geomembrane with Excellent Chemical Resistance and High Temperature Resistance

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

1. 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).

2. 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.

3. 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.

4. Environmental Compliance

   • Meets EPA, MSHA, and global mining waste containment standards.

   • Prevents groundwater contamination and protects ecosystems from hazardous leachates.

5. 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.

Installation Guidelines

1. Prepare a compacted, smooth subgrade free of sharp protrusions.

2. Weld seams using dual-track hot wedge equipment for fail-safe joints.

3. Anchor perimeter into trenches and backfill with compacted soil.

4. Conduct rigorous QA/QC testing (e.g., destructive/non-destructive seam tests).
