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.
HDPE geomembranes are extensively used in water management projects, such as canal lining, reservoir sealing, and agricultural ponds. In arid and semi-arid regions where water scarcity is a concern, these sheets help in preventing seepage losses from water storage structures. They are particularly useful in preventing the contamination of drinking water sources by external pollutants.
