HDPE Black One-Sided Textured (OST) Geomembrane
(1 Product Views)
Product description
Engineered for demanding containment applications, this HDPE Black One-Sided Textured (OST) Geomembrane combines the chemical resistance of high-density polyethylene with a specialized surface texture. The textured side features an asperity height of 0.25mm, which significantly enhances friction and interlock with surrounding soils, backfill materials, or geosynthetics. This design prevents slippage on slopes and improves the stability of the liner system under dynamic loads.
Key Features & Specifications
- Material: 100% Virgin HDPE for maximum durability and purity.
- Thickness Options: Available in 1.5mm, 2.0mm, and 2.5mm to suit various project requirements.
- Surface Texture: One-sided texture with 0.25mm asperity height for enhanced shear strength.
- Density: ≥ 0.94 g/cm³, ensuring consistent performance and resistance to environmental stress cracking.
- Stress Crack Resistance: ≥ 500 hours, providing long-term reliability in harsh conditions.
Applications
This geomembrane is ideal for landfill liners, mining tailings ponds, water reservoirs, and agricultural ponds where slope stability and anti-seepage performance are critical. The black color provides excellent UV resistance, extending the lifespan of the installation when exposed to sunlight.
