|---|---|---|---|---|
| HDPE (1.5mm) | 5.5 – 12.5 | High | Excellent | Landfill, mining |
| LDPE | 4.5 – 10 | Medium | Good | Ponds, agriculture |
| PVC | 6 – 14 | Medium | Moderate | Waterproofing |
| EPDM | 8 – 18 | High | Moderate | Decorative ponds |
Application Scenarios
EPC Contractors: Landfill liners, tailings dams
Developers: Industrial wastewater containment
Distributors: Bulk supply to regional projects
Engineering Firms: Environmental protection systems
Core Pain Points & Solutions
Cost Uncertainty: Use BOQ-based estimation and site survey before procurement
Welding Failure: Require certified technicians and double-track welding
Material Degradation: Select UV-stabilized geomembrane with certified carbon black dispersion
Subgrade Damage: Install geotextile cushion layer to prevent puncture
Risk Warnings & Mitigation
Improper subgrade leads to liner puncture → Conduct compaction and debris removal
Poor welding causes leakage → Perform vacuum box and air pressure testing
Low-quality material → Verify third-party test reports (SGS, BV)
Weather impact → Avoid installation under extreme temperature or rain
Procurement & Selection Guide
Define project application and chemical exposure
Select thickness (1.5mm for most heavy-duty applications)
Request GRI-GM13 compliance reports
Evaluate supplier production capacity and export experience
Compare total installed cost, not just material price
Confirm welding equipment and installation team capability
Request samples for testing before bulk order
