High-Density Geomembrane - Multi-Standard Impermeable Solution for Global Projects

Product Description

Textured HDPE Geomembrane for Mine Slope Anti-Seepage

The Textured HDPE Geomembrane is a specialized anti-seepage material engineered for slope applications in mining areas. Manufactured from premium HDPE resin with UV stabilizers and anti-aging additives, this product features a rough textured surface on one or both sides to significantly increase friction coefficients and prevent slippage on steep slopes.

Product Specifications

Thickness Range: 0.8mm to 3.0mm
Surface Roughness: Ra ≥3.0μm
Friction Coefficient: ≥0.5
Permeability Coefficient: ≤1.0*10⁻¹³ cm/s
Temperature Resistance: -60℃ to 80℃
Maximum Slope Ratio: 1:1.2

Key Features & Benefits

Enhanced Anti-Slip Performance: Textured surface increases friction coefficient to prevent geomembrane slippage on steep slopes, ensuring system integrity
Reliable Anti-Seepage Protection: Ultra-low permeability coefficient effectively isolates mining chemicals and prevents soil and groundwater contamination
Superior Weather Resistance: Withstands extreme temperatures and prolonged UV radiation, adapting to harsh mining area conditions
Excellent Weldability & Mechanical Strength: Ensures easy installation and provides long-term service life in demanding environments

Application Scenarios

This geomembrane is specifically designed for slope anti-seepage applications in mining operations, including:

Mine tailings dam slopes
Waste rock dump slopes
Open-pit mine pit slopes
Leachate pond slopes
Slope-type wastewater storage ponds
Slope-type chemical storage ditches

Suitable for various mine types including metal mines, coal mines, and non-metallic mines, particularly where anti-slip performance is critical on steep slopes.

Installation Guidelines

Position textured surface upward (contact with slope soil) to maximize friction; for containment structures, face textured surface toward soil or filler
Ensure slope surface is flat and free of sharp objects before installation
Lay geomembrane from bottom to top with 15-20cm overlaps between adjacent membranes
Use HDPE welding machine for seams; employ special welding nozzle for textured surfaces
Secure top and bottom with anchor grooves or anchor bolts to prevent displacement
Conduct comprehensive leak testing (air pressure or water filling test) post-installation
Avoid dragging heavy objects across geomembrane surface to protect textured layer
