Double-Sided Textured HDPE Geomembrane ASTM GM13 for Steep Slope Landfill Dam Stability Enhanced Friction Angle

Double-Sided Textured HDPE Geomembrane - Enhanced Slope Stability

Featuring a co-extruded textured surface on both sides, this HDPE geomembrane provides significantly enhanced interface friction with soil, geotextile, and other geosynthetic layers. The textured profile increases the friction angle, making it the preferred choice for steep slope applications in landfill and dam projects.

Textured Surface Benefits

• Double-sided texture for maximum interface friction
• Co-extruded texture - integral to the membrane structure
• Increased friction angle: ≥30° with sand, ≥26° with geotextile
• Preserves full impermeability while improving stability
• Asperity height: 0.4-0.8mm for optimal soil interlock

Recommended Uses

Landfill side slope liners (≥3H:1V), dam upstream facing, tailings dam slope protection, heap leach pad sidewalls, and any application where slope stability is critical.
