Core Pain Points & Engineering Solutions
Leakage risks → Multi-layer co-extrusion + seamless high-width rolls reduce joints
UV exposure damage → Carbon-black UV stabilization enhances outdoor durability
Tear/puncture during installation → High puncture resistance & textured options for slope stability
Settlement & ground deformation → Flexible LLDPE versions withstand substrate movement
Risk Warnings & Preventive Measures
Sharp stones must be removed; geotextile recommended as cushion layer
Overlap seams must follow GRI GM13 welding standards
Site quality inspection required：spark test & vacuum box testing
Record installation temperatures：avoid excessive thermal shrinkage
Procurement & Selection Guide
Select HDPE or LLDPE based on ground settlement requirements
Request tensile & puncture test reports according to GRI-GM13
Confirm carbon-black content for long-term UV exposure
Check roll dimensions for minimizing welding workload
Verify project-based warranty & lifetime simulation
Ensure supplier has welding equipment & onsite QC support
Engineering Case Study
A Southeast Asian shrimp farming EPC project required high waterproof reliability under strong UV exposure. 180,000 m² of 1.5mm HDPE geomembrane was deployed with double-seam extrusion welding. Leakage rate reduced by 85% vs. previous PVC liners. 12-month inspection showed no visible crack or joint failure despite soil settlement.
