Product Description

HDPE Rough Surface Geomembrane

Specialized geomembrane with cylindrical point texture for enhanced anti-slip performance and structural stability in reservoir dam applications.

Product Overview

Cylindrical rough surface geomembrane features specialized surface textures designed to significantly improve anti-slip performance and adhesion in critical anti-seepage engineering applications.

Key Properties

Surface Texture: Columnar or point-like patterns providing additional friction to prevent sliding on slopes
High Friction Coefficient: Enhanced grip for maintaining stability on slopes and vertical surfaces
Superior Impermeability: Maintains excellent water and pollutant penetration resistance
Chemical Corrosion Resistance: Withstands erosion from various chemical substances
Environmental Stress Crack Resistance: Maintains stability and resists cracking in harsh conditions
Temperature Adaptability: Excellent heat resistance and cold resistance for diverse climatic applications

Applications

Tailings Ponds: Seepage prevention and stabilization to contain harmful substances
Water Conservancy Projects: Reservoirs and dams requiring enhanced structural stability
Slope Engineering: Stability enhancement on steep slopes and soft soil conditions
Landfill Sites: Anti-slip and anti-seepage applications for improved safety

Product Series

Available in single textured geomembrane and double-wall textured geomembrane configurations.
