Description
Smooth HDPE Geomembrane for Mine Tailings Pond Anti-Seepage
Product Overview

Our Smooth HDPE Geomembrane is a high-performance anti-seepage material specifically engineered for mine tailings ponds, leachate ponds, and other critical water containment structures. Manufactured from 100% virgin HDPE resin using advanced extrusion molding technology, this geomembrane features a smooth surface with uniform thickness and exceptional impermeability.

Permeability Coefficient ≤1.0*10⁻¹³ cm/s
Thickness Range 0.5mm to 3.0mm
Width Range 2m to 8m (customizable)
Key Features & Benefits
  • Ultra-Low Permeability: Forms a complete impermeable barrier to prevent leakage of harmful substances including cyanide, sulfide, heavy metals, and leachate
  • Chemical Corrosion Resistance: Withstands long-term erosion by acids, alkalis, salts, organic solvents, and other chemicals common in mining operations
  • Superior Mechanical Properties: Tensile strength ≥28MPa and elongation at break ≥500% to withstand puncture, tear, and deformation
  • Enhanced Weather Resistance: UV stabilizers provide protection against sunlight radiation and extreme temperature variations
Application Scenarios

This geomembrane is specifically designed for:

  • Mine tailings ponds (core facility for storing mine tailings)
  • Leachate collection ponds (for collecting and treating leachate from tailings and waste rock)
  • Mine wastewater storage ponds
  • Coal ash ponds in coal mines
  • Chemical storage tanks in mining smelting workshops
  • Groundwater protection barriers in mining areas

Widely applied in metal mines, coal mines, and non-metallic mines, particularly in regions with stringent environmental protection requirements.

Installation & Usage Guidelines

Surface Preparation: Ensure base surface is flat, clean, and free of sharp objects (stones, glass, steel bars). Fill pits and uneven areas with sand or fine soil.

Laying Requirements: Avoid tension and wrinkles during installation. Overlap adjacent membranes by 10-15cm (thickness ≤1.5mm) or 15-20cm (thickness >1.5mm).

Welding Specifications: Use HDPE welding machine with welding strength ≥80% of base material. Conduct air pressure testing (pressure ≥0.2MPa, holding time ≥5 minutes) to verify integrity.

Storage & Protection: Avoid prolonged direct sunlight exposure before installation. Cover with tarpaulin if not used immediately.

Maintenance: Regularly inspect for damage and repair any leaks or tears promptly using special welding rods.
