Custom HDPE Geomembranes from Haoyang: Tailored HDPE Liners for Hydrometallurgy, Salt Lake, Cold Regions & Pumped Storage Projects

As a professional manufacturer specializing in customized geosynthetic containment solutions, Haoyang Environmental Co., Ltd. develops application-specific HDPE geomembrane products to solve critical pain points across harsh global engineering scenarios. Conventional standard geomembranes fail to meet differentiated anti-seepage demands for mining, hydropower and extreme climate projects. Through long-term joint R&D with research institutes, Haoyang launches four series of proprietary HDPE geomembranes, paired with systematic anti-leakage solutions to match unique working conditions worldwide.

1. HDPE Geomembrane for Hydrometallurgy Plants

Hydrometallurgy facilities face constant erosion from hydrogen peroxide, ozone, high-concentration acid, alkali and brine mixtures. Haoyang’s dedicated metallurgical geomembrane adopts an oxidation-resistant formula that boosts anti-corrosion capacity by 3 times against complex chemical media.

Built with five-layer co-extrusion structure and nano functional reinforcement layers, this liner carries a designed service life of 5–8 years and cuts routine maintenance frequency by 60%. It perfectly fits heap leaching pools, solution storage tanks and all wet metallurgy production lines with intensive chemical exposure.

2. HDPE Geomembrane for Frigid & Extreme Temperature Regions

Most standard HDPE geomembranes turn brittle and crack under low temperatures, causing hidden leakage risks. Haoyang’s cold-resistant geomembrane passes over 700 hours of NCTL testing under ASTM D5397 standards, lifting crack propagation resistance by 80% and eliminating brittle fracture triggered by stress concentration. Integrated UV resistance, acid-alkali tolerance and freeze-thaw resistance, the material maintains stable flexibility at temperatures ranging from -70°C to 40°C, delivering a service lifespan exceeding 50 years. Even at -30°C, the HDPE liner retains excellent elasticity, ideal for alpine reservoirs, northern landfills and year-round large temperature fluctuation projects.

3. HDPE Geomembrane for Salt Lake & Mine Operations

Salt lake environments feature sharp salt crystal piercing, abrasive sand wind and continuous high-salinity brine corrosion. Compared with ordinary geomembranes, Haoyang’s salt lake grade liner achieves 20% higher tensile performance, 60% improved impact resistance and 50% stronger puncture resistance, while abrasion loss drops by two-thirds.

Extra low friction and self-lubricating surface reduce abrasion during installation; its robust chemical barrier blocks brine penetration for over 20 years with zero leakage. The material withstands salt crystal piercing and wind sand scouring, fully matching the full-cycle operation needs of lithium salt lakes and open-pit mines.

4. Spray-Textured HDPE Geomembrane for Pumped Storage Power Stations

Slope stability is the core challenge for pumped storage reservoir liners. Haoyang completed independent direct shear friction coefficient tests to compare its patented spray-textured geomembrane against traditional nitrogen-textured geomembrane, releasing authoritative reference data for hydropower designers:

• Haoyang spray-textured geomembrane: transverse friction coefficient 0.485, longitudinal 0.455, average 0.470

• Nitrogen textured geomembrane: transverse friction coefficient 0.397, longitudinal 0.369, average 0.383

Test data proves Haoyang spray-textured geomembrane raises transverse friction performance by 22.2% and longitudinal friction by 23.3%. Higher interface friction effectively prevents liner sliding on steep reservoir slopes, improving the overall stability of anti-seepage systems for high-water-pressure pumped storage projects.

Why Choose Haoyang Custom HDPE Geomembranes?

1. Scenario-targeted formulation: Each HDPE geomembrane series is engineered for specific harsh working environments instead of generic universal materials.

2. Verified authoritative test data: All performance indicators comply with GB/T 17643 and GRI-GM13 standards, supported by complete traceable lab reports.

3. Patented one-step spray-texturing technology: Single/double textured surfaces with stronger coating adhesion than two-step offline texturing.

4. Full solution support: Beyond geomembrane supply, Haoyang provides professional construction guidance and customized anti-seepage system design.

Haoyang’s HDPE geomembranes have been exported to more than 70 countries, widely adopted in global hydrometallurgy, lithium salt lake, cold-area infrastructure and pumped storage hydropower projects.
