Rough Geomembrane
The double rough surface geomembrane is a specialized geosynthetic material that is highly effective in slope seepage control. Its dual-roughened design enhances adhesion and stability when in contact with soil or other materials, making it an ideal barrier for reducing water infiltration and erosion. When used as a lining on slope surfaces, the geomembrane forms an impermeable layer that prevents water and contaminants from penetrating into the soil layers beneath. This not only stabilizes the slope but also safeguards groundwater resources from potential pollution. Additionally, the geomembrane's strong adherence to the soil improves the overall stability of the slope. Integrated with other slope treatment measures like drainage systems and vegetation restoration, the double rough surface geomembrane provides a comprehensive solution for slope seepage control, ensuring long-term stability and environmental protection.
When it comes to slope seepage control, not all liners are created equal. The Double Rough Surface Geomembrane is purpose-built for challenging terrains where traditional smooth liners may slip or fail. Designed with dual-textured surfaces, this advanced HDPE geomembrane provides enhanced frictional strength, superior seepage resistance, and long-term durability—making it the go-to solution for engineers and contractors working on dams, landfills, reservoirs, and mining slopes.
What Is a Double Rough Surface Geomembrane?
Unlike smooth liners, the double rough surface geomembrane features raised textures on both sides. This engineered design:
Increases the interface friction angle
Improves slope stability
Enhances soil-geomembrane interaction
Maintains high impermeability under high loads
Perfect for steep slopes and embankments, it meets both geotechnical and hydraulic engineering standards.
✅ Key Features at a Glance
⚙️ Dual Textured Surface
The double-sided roughness offers maximum interlocking with adjacent materials, preventing slippage and ensuring your liner stays in place, even on sharp inclines.
? Excellent Seepage Control
With a low permeability coefficient (≤1.0×10⁻¹³ cm/s), this geomembrane forms an impermeable barrier that effectively prevents water infiltration and leachate migration.
? High Tensile Strength
Manufactured with premium HDPE resin, this geomembrane delivers high tensile and puncture strength, ideal for demanding construction environments.
☀️ UV and Chemical Resistance
Built to resist UV degradation, chemical corrosion, and microbial attack, it’s suitable for outdoor long-term exposure, even in harsh climates.
?️ Easy Welding, Seamless Installation
Compatible with thermal fusion welding, it ensures seam integrity and easy on-site installation using standard geomembrane welding machines.
