Textured Geomembrane is an engineered polyethylene membrane featuring a specially designed rough surface texture for enhanced friction and superior interface shear strength. Ideal for slope stabilization, landfill liners, and hydraulic applications, this product combines durability with exceptional anti-slip properties to ensure long-term project integrity.
Key Features
Dual-Surface Texture: Sandpaper-like finish on one or both sides for maximum friction resistance.
Material Excellence: Manufactured from premium-grade HDPE/LLDPE resin with UV stabilization and chemical resistance.
Shear Strength Optimization: Reduces interface slippage in steep slopes and high-stress environments.
Customizable Thickness: Available in 0.75mm to 3.0mm thicknesses to meet project-specific requirements.
Environmental Resilience: Resists punctures, tears, and biological degradation, suitable for harsh conditions.
Applications
1.Landfill liners & caps
2.Mining heap leach pads
3.Reservoir & canal linings
4.Road and railway embankments
5.Wastewater treatment ponds
