Anti-Slip Rough Surface Textured Geomembrane

This rough surface geomembrane is manufactured from polyethylene raw materials with optimized blow molding equipment, adopting nitrogen roughening, water roughening or surface spraying craft to form uniform raised textures on one or both sides. Different from smooth HDPE Geomembrane, this product greatly elevates surface friction coefficient and delivers reliable anti-slip performance, solving the slipping risk on steep and vertical anti-seepage slopes efficiently. During on-site installation, small hollow gaps form between the rough geomembrane and foundation soil, which improves load-bearing deformation resistance and prevents tensile rupture under long-term soil pressure. It can work independently or be matched with Geotextile for double-layer protection, avoiding puncture damage from sharp rock fragments. When combined with Composite membrane, it builds a complete anti-seepage system without extra complicated laying steps. Shandong Hengyang supplies standardized rough geomemb…
