Product Description
Product Overview
HDPE Column Point Rough Surface Geomembrane is a specialized impermeable liner featuring columnar or point-like surface textures that significantly enhance friction coefficient and surface adhesion for superior stability on slopes and vertical applications.
Key Properties
- Enhanced Friction Coefficient: Column point design provides superior grip for stability on slopes up to 1:1.5
- Exceptional Impermeability: Maintains core geomembrane function with water and pollutant penetration resistance
- Chemical Corrosion Resistance: Withstands exposure to various chemical substances in diverse environments
- Environmental Stress Crack Resistance: Maintains structural integrity and stability in harsh conditions
- Temperature Adaptability: Excellent heat resistance and cold resistance performance across different climatic conditions
Applications
- Slope Engineering: Anti-slip and anti-seepage protection for slopes, particularly steep inclines
- Landfill Systems: Slope protection in landfills to prevent pollutant infiltration and landslides
- Tailings Ponds: Seepage prevention and stabilization to contain harmful substances
- Water Conservancy Projects: Enhanced impermeability for reservoirs, dams, and hydraulic structures
