1.0mm (40 mil) Textured LLDPE Geomembrane | High Friction Liner for Slope Stability & Capping

PRODUCT DETAILS
1. Product Overview
Maximum Grip. Maximum Flexibility. The Ultimate Slope Solution.
Engineering a containment system on steep slopes or unstable ground requires more than just waterproofing. Our 1.0mm (40 mil) Textured LLDPE Geomembrane provides the perfect dual-solution. By combining the superior elongation of Linear Low-Density Polyethylene with a rough, high-friction surface, this liner prevents slope slippage while accommodating significant differential settlement. It is the industry standard for Landfill Capping (Closures) and environmentally sensitive embankments where ground movement is expected.
2. Key Features
-
High Friction Coefficient: The integrated textured surface (available Single or Double-Sided) drastically increases the interface friction angle, preventing the soil cover or geotextiles from sliding off steep slopes.
-
Settlement Resistant: Unlike rigid HDPE, our LLDPE liner offers exceptional multi-axial elongation. It stretches to bridge voids caused by waste decomposition or subgrade shifting without stress cracking.
-
Durable 40 mil Thickness: The 1.0mm profile offers excellent puncture resistance against root penetration and installation damage, suitable for long-term containment.
-
Cold Weather Flexibility: Maintains pliability and integrity in freezing conditions, making it easier to install on slopes in winter compared to stiff HDPE sheets.
-
Interface Stability: Specifically engineered to interlock with Geotextiles and GCLs (Geosynthetic Clay Liners), creating a stable, unified lining system.
3. Detailed Application Scenarios
Landfill Capping & Closures (Final Cover)
This is the #1 application for this product. As landfill waste decomposes, the pile settles unevenly. A rigid liner would crack, but our Textured LLDPE stretches to accommodate the subsidence. Simultaneously, the textured surface holds the topsoil and vegetation layer in place, preventing landslides on the cap.
Mining Heap Leach Pad Slopes
For side slopes in mining operations, you need a liner that won't let the valuable ore pile slide. The 1.0mm Textured LLDPE provides the necessary grip while enduring the harsh chemical environment (Note: For heap leach bottoms, HDPE is usually preferred; LLDPE is preferred for caps or areas needing high elongation).
Unstable Embankments & Levies
In civil engineering projects where the subgrade soil is soft or prone to shifting, Textured LLDPE ensures that the waterproofing layer remains intact even if the ground below moves, while keeping the protective cover soil stable.

5. Why "Textured LLDPE" and not "Textured HDPE"?
-
Select Textured LLDPE (This Product) when: You expect settlement (like on a landfill cap), the subgrade is soft/uneven, or you need easier installation on slopes in cold weather.
-
Select Textured HDPE when: The ground is perfectly stable/compacted (like a new landfill bottom cell) and maximum chemical resistance is the absolute priority.
