HDPE Geomembrane is the industry-leading impermeable lining solution designed for the rigorous demands of tailings storage facilities (TSFs), mining operations, and industrial waste containment. Manufactured from high-density polyethylene, this robust geomembrane delivers unmatched resistance to acids, alkalis, and corrosive chemicals while providing a near-zero permeability barrier to safeguard against environmental contamination. Ideal for long-term containment of toxic tailings, slurry, and leachates, HDPE geomembranes ensure compliance with global environmental regulations and operational safety standards.
Unrivaled Chemical Resistance
Withstands prolonged exposure to acids, alkalis, hydrocarbons, and heavy metals (pH 0.5–14), preventing degradation and maintaining structural integrity.
Superior to PVC or LLDPE geomembranes in corrosive environments common to mining and mineral processing.
Zero Leaks, Zero Risks
Ultra-low permeability (<1×10⁻¹³ cm/s) creates an impervious shield against seepage, protecting groundwater and surrounding ecosystems.
Seam strength exceeds 90% of base material via advanced thermal fusion welding, ensuring lifetime leak-free performance.
Crack & Puncture Resistance
High tensile strength (≥25 MPa) and flexibility resist ground settling, seismic shifts, and mechanical stresses.
UV-stabilized formulations prevent brittleness and cracking, even in extreme temperatures (-60°C to +80°C).
50+ Year Lifespan
Engineered for permanent containment with minimal maintenance, reducing lifecycle costs by up to 70% compared to clay or concrete alternatives.
| Feature | HDPE Geomembrane | Clay Liners | Concrete Barriers |

Tailings Dams & Ponds: Securely contain toxic slurry and prevent groundwater contamination.
Heap Leach Pads: Resist corrosive cyanide and sulfuric acid solutions.
Evaporation Ponds: Durable lining for salt and brine containment.
Capping Systems: Post-closure sealing to meet environmental remediation standards.
Subgrade Preparation: Level and compact the base; remove sharp debris.
Unroll & Align: Deploy prefabricated HDPE sheets with 150mm seam overlaps.
Welding: Use dual-track thermal fusion for airtight, high-strength seams.
Quality Assurance: Conduct spark testing and seam peel tests to ensure integrity.
*"After switching to HDPE geomembranes for our copper mine’s tailings dam, we eliminated seepage-related compliance issues. Even after 8 years of acidic exposure, the liner shows no signs of wear."*
