Textured HDPE Geomembrane
Textured HDPE Geomembrane Textured High-Density Polyethylene (HDPE) Geomembrane is an impermeable barrier material manufactured with a uniform rough surface texture (single or double-sided) through specialized processes. Composed primarily of HDPE (density ≥ 0.940 g/cm³), its textured design enhances frictional resistance and anti-slip performance, making it ideal for steep slopes and high-friction applications in containment systems. Core Characteristics Anti-Slip & Stability Textured surface significantly increases friction coefficient, preventing soil cover slippage on steep slopes (e.g., ≥1:3 gradients). High Strength & Durability Temperature resistance: -70℃ to 110℃; UV resistance, chemical corrosion resistance (acids, alkalis, salts, oils); High elongation at break, accommodates substrate settlement. Impermeability Hydraulic conductivity ≤ 10⁻¹⁷ cm/s (effectively impervious). Puncture Resistance Resists root penetration and sharp aggregate damage.
