Geomembranes are high-performance, impermeable synthetic liners designed to provide secure containment for industrial and environmental applications. Made from durable polymers like HDPE, LLDPE, and PVC, they offer superior chemical resistance, puncture resistance, and long-term durability—making them ideal for tailings storage facilities (TSFs) in mining operations.
✅ Impermeable Barrier – Blocks harmful chemicals, heavy metals, and acidic leachates from seeping into groundwater.
✅ Environmental Compliance – Meets EPA, ICMM, and global mining regulations for safe tailings disposal.
✅ Prevents Erosion & Slope Failure – Reinforces tailings dams and storage ponds.
✅ Reduces Water Infiltration – Minimizes the risk of liquefaction and dam breaches.
✅ Lined Collection Systems – Allow for efficient water recovery from tailings.
✅ Reduces Freshwater Consumption – Supports sustainable mining practices.
✅ Lower Maintenance – Resists UV degradation, chemical corrosion, and punctures.
✅ Extends Facility Lifespan – 30+ years of reliable performance with proper installation.
| Feature | Geomembrane | Clay Liner |
|---|---|---|
| Permeability | Nearly Zero (10⁻¹⁵ m/s) | Higher (10⁻⁷–10⁻⁹ m/s) |
| Installation Speed | Fast (Prefabricated rolls) | Slow (Requires compaction) |
| Chemical Resistance | Excellent (HDPE resists acids, alkalis) | Poor (Erodes with acidic tailings) |
| Thickness Options | 0.5mm – 3.0mm (Customizable) | Fixed (Requires thick layers) |
| Lifespan | 30+ Years (UV-stabilized) | 10-20 Years (Degrades faster) |
