High Density Polyethylene (HDPE) Geomembrane for Copper Tailing
PRS (Sichuan Precision Technology Co., Ltd.) produces HDPE geomembranes using advanced 5-layer co-extrusion technology and 10-meter-wide dual-textured production lines (0.2–2.5mm thickness), ensuring zero pinholes and high hydrostatic resistance. With 12,000-ton annual capacity, fully automated PLC control, and a CNAS-certified lab, we guarantee quality from raw materials to finished products. Our 9-meter-wide geomembranes reduce seams by 9-10%, cutting costs (e.g., saving 30,000㎡ in a 300,000㎡ project). Ideal for landfills, mining, and water projects.

Quality Assurance Measures
Quality Assurance and Control Process Flowchart
Raw Material Quality Control
Set Standards: Define internal criteria for raw/auxiliary materials.
Inspect & Test: Check samples upon arrival against standards.
Retain Samples: Archive tested samples for traceability.
Approve/Reject: Use only compliant materials; discard non-compliant ones.
Production Process Quality Control
Quality Control of Finished Products
Zoned Storage: Products are placed in a pending inspection area post-production.
Sampling & Testing: Assessed against corporate standards.
Segregation: Passed products move to qualified area; failed ones to non-qualified area.
Goal: Guarantee only compliant products reach the market.
Traceability
Product Traceability
Key Advantages of HDPE Geomembrane Production
5-layer co-extrusion: Eliminates pinholes, ensures uniform thickness, enhances hydrostatic pressure resistance, and enables textured/black-green membranes.
150mm screw: High production capacity for timely delivery.
Dual friction rolls + inflatable shaft: Neat winding for easy transport.
Computer-controlled system: Guarantees precise thickness/width.
9m width: Reduces seams by 9-10% vs. 5.8m, saving material (e.g., 30k㎡ saved in a 300k㎡ project).
Result: Lower leakage risk and significant cost efficiency.
The Combined Laying Method of Geomembrane and Geotextile
- Base Layer: Compacted soil provides stability.
- Drainage Network: Manages water flow to prevent pooling.
- Impermeable Barrier: HDPE geomembrane prevents fluid leakage.
- Protective Layer: Non-woven geotextile protects the geomembrane and allows filtration.
