High Chemical Resistance HDPE Geomembrane for Mining Tailings Seepage Control
Product Summary
Haoyang's HDPE geomembrane is engineered for demanding mining tailings and metal smelting applications. Available in thicknesses from 0.3mm to 3.0mm, it provides exceptional chemical resistance, UV stability, and long-term durability. Our textured geomembrane (used in the Uzbekistan gold mine project) features a five-layer co-extrusion process for superior bond strength and reduced energy consumption.
Key Selling Points
- Chemical & UV Resistance: Withstands acidic and alkaline leachates; carbon black content 2.0–2.8% for UV protection (source_fact: params, special_requirement from scen).
- High Mechanical Strength: Break strength up to 85 kN/m, puncture resistance up to 1200 N (source_fact: params).
- Proven in Mining Projects: Supplied 900,000 m² for a gold mine tailings pond seepage control in Uzbekistan (source_fact: case).
- Five-Layer Co-Extrusion Textured Surface: Molecular-level bonding of rough points, 25% energy reduction, no thermal aging risk (source_fact: case).
- International Certifications: GOST (56586-2015) and CE (EN 13249:2016) certified (source_fact: certs).

Models and Options
Available in smooth or textured finish. Thicknesses from 0.3mm to 3.0mm. Roll width up to 8m (custom). Five-layer co-extrusion textured geomembrane is a key model for mining.
Materials and Structure
Virgin HDPE resin, with carbon black and antioxidants. Textured surface achieved via high-temperature air jet process during co-extrusion, forming molecular-level bond with substrate.
Applications
Specifically designed for metal smelting tailings ponds, heap leach pads, and mining containment. Suitable for hazardous waste liquid containment with high chemical resistance requirements. Operates 24/7.
Customization
Thickness, roll dimensions, and texturing can be customized. MOQ 5000 m². Acceptance via pre-shipment testing. Packaging as per requirements.
Case Study
Uzbekistan Gold Mine Tailings Pond Basin Seepage Control
Quantity: 900,000 m² | Duration: 70 years | Client: Mining and Smelting Engineering
We supplied textured geomembrane produced on a five-layer co-extrusion line. The project used a 3D composite drainage network achieving full-chain service from supply to installation. Result: perfect seepage control.
