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) |
This geomembrane is specifically designed for:
Widely applied in metal mines, coal mines, and non-metallic mines, particularly in regions with stringent environmental protection requirements.
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.
