Our Smooth HDPE Geomembrane is manufactured using 100% virgin polyethylene resin with carbon black and specialized additives. Produced through advanced four-layer extrusion blown film technology, it offers superior thickness uniformity and mechanical stability compared to traditional calendared geomembranes.
Certified to CE standards, this geomembrane delivers exceptional impermeability, strength, and long-term durability for critical containment applications. Available in custom colors upon request.
✔ Superior Impermeability - Hydraulic conductivity <10⁻¹³ g·cm/(cm²·s·Pa)
✔ UV & Weather Resistance - Carbon black provides excellent aging resistance
✔ Chemical & Biological Resistance - Withstands acids, alkalis, oils, and microbial degradation
✔ High Tensile Strength & Elongation - Excellent puncture and tear resistance
✔ Extreme Cold Flexibility - Remains flexible even at temperatures below -70°C
✔ Long Service Life - 70+ years lifespan under normal conditions
• Environmental: Landfill liners, wastewater treatment lagoons
• Water Conservancy: Reservoirs, irrigation ponds, canals
• Aquaculture: Fish/shrimp farming pond liners
• Industrial: Mining leach pads, oil/gas containment
• Civil Engineering: Tunnels, landscaping, secondary containment
