High-Density Polyethylene HDPE Geomembrane Chemical Resistance Leak Prevention for Tailings Storage Facilities

Product Overview

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.

Key Advantages for Tailings Management

1. 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.

2. 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.

3. 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).

4. 50+ Year Lifespan

   • Engineered for permanent containment with minimal maintenance, reducing lifecycle costs by up to 70% compared to clay or concrete alternatives.

Applications in Tailings Management

• 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.

Installation Excellence

1. Subgrade Preparation: Level and compact the base; remove sharp debris.

2. Unroll & Align: Deploy prefabricated HDPE sheets with 150mm seam overlaps.

3. Welding: Use dual-track thermal fusion for airtight, high-strength seams.

4. Quality Assurance: Conduct spark testing and seam peel tests to ensure integrity.
