Core Functional Performance
All performance indicators are optimized for long-term tailings pond operation to solve mining environmental protection pain points:
- Puncture Resistance: Dense molecular structure withstands piercing damage from sharp tailings gravel and ore residues, avoiding membrane rupture and leakage.
- Chemical Corrosion Resistance: Effectively isolates acidic, alkaline and heavy metal-containing tailings leachate to prevent soil and groundwater contamination.
- Anti-Aging Stability: Formulated with anti-UV and anti-oxidant additives, maintaining stable physical properties under long-term outdoor exposure and buried conditions.
PRS On-Site Welding & Construction Service
Material quality determines basic seepage resistance, while standardized welding construction determines the overall stability of the tailings liner system. PRS provides two flexible construction cooperation modes for global mining projects.
- Technical Guidance Service: Arrange professional engineers to guide on-site laying, hot-melt welding, seam inspection and edge sealing, standardizing local construction operations.
- Full Turnkey Contracting: Undertake the whole process of geomembrane laying, welding, testing and acceptance, delivering fully qualified tailings anti-seepage projects.
PRS Professional Factory Testing Equipment
All PRS mining geomembranes undergo strict factory testing before delivery to ensure compliance with international mining geosynthetic standards:
- Geomembrane Tensile Tester: Detects tensile strength and elongation at break to verify the ductility and deformation resistance of geomembrane under foundation stress.
- UV Accelerated Weathering Tester: Simulates long-term outdoor ultraviolet exposure to evaluate the material’s anti-aging performance in open-air tailings pond environments.
- Geosynthetics Static Hydraulic Pressure Tester: Tests the hydraulic pressure resistance and overall seepage prevention performance of finished geomembrane rolls.
Export Packaging & Shipment Standard
PRS tailings geomembranes adopt standardized export packaging, suitable for bulk ocean freight and 40’HQ container transportation, effectively avoiding damage during long-distance shipping:
- 5.8m width geomembrane rolls, customized packaging for 40’HQ container loading
- 6.8m wide geomembrane fixed with professional steel frame, stable for bulk freighter transportation
- 8m ultra-wide geomembrane roll packaging, reducing on-site splicing times for large-scale tailings projects
Application Scope
Primarily engineered for mining environmental protection scenarios, this export-grade HDPE geomembrane is widely used for non-ferrous metal mine tailings ponds, tailings dam anti-seepage, tailings storage yard lining and mine closure seepage control. Meanwhile, its excellent corrosion resistance and waterproof performance also adapt to general industrial anti-seepage projects, including landfill lining, reservoir and canal water conservancy projects, and industrial wastewater anti-leakage treatment.
