Premium Spray-Textured HDPE Geomembrane with Uniform Surface Roughness for Superior Interface Shear Strength

Product Description:
Our Spray-Textured HDPE Geomembrane is engineered through an advanced secondary extrusion process where a coating of textured material is uniformly sprayed onto one or both sides of a smooth HDPE sheet during manufacturing. This creates a consistent, high-friction surface with controlled roughness. Unlike co-extruded textured membranes, the spray-on method allows for a more random and aggressively rough pattern, which directly translates to significantly higher interface shear strength with geosynthetics and soils. This membrane retains all the excellent properties of a standard HDPE geomembrane—exceptional chemical resistance, low permeability, and high durability—while adding the critical benefit of enhanced slope stability, making it the intelligent choice for demanding applications where security is paramount.

Key Features:

• Advanced Spray-Texture Process: Delivers a uniformly rough, high-friction surface for maximum interface shear resistance.

• Exceptional Shear Strength: Provides superior resistance to slippage on slopes when interfacing with geotextiles or soils.

• Maintained HDPE Integrity: Offers the same excellent chemical resistance, tensile strength, and durability as smooth HDPE.

• Available in Single or Double-Sided Texturing: Flexibility for specific design needs in composite liner systems.

Technical Specifications:

• Width: 5m - 8m

• Thickness: 1.0mm - 2.5mm

• Roll Length: 50m - 100m (Custom lengths available)
