2.Water conservancy projects: Used in reservoirs, canals, and dams to enhance impermeability and improve water storage.
3.Water treatment plants: Line sedimentation tanks and filter pools to avoid sewage leakage.
4.Agricultural irrigation: Line irrigation canals to reduce water seepage loss and save water resources.
5.Mining industry: Line tailings ponds to prevent heavy metal wastewater from contaminating the environment.
6.Ecological restoration: Used in wetland reconstruction and riverbank protection to maintain ecological balance.
Ⅶ. On-Site Installation Steps of Smooth HDPE Geomembrane
1.Site preparation: Clear debris, level the ground, and compact the soil to ensure a flat, solid foundation without sharp objects.
2.Geomembrane unrolling: Unroll the geomembrane along the project direction, avoid wrinkles, and leave a 10-15cm margin for splicing.
3.Splicing operation: Use hot wedge welding, ensure a welding width of 10cm, and test the weld for air tightness to avoid leakage.
4.Laying and fixing: Lay the spliced geomembrane on the foundation, fix edges with anchor trenches or weights to prevent displacement.
5.Inspection and repair: Check for holes or poor splicing; repair damaged areas with the same material using welding.
6.Backfilling protection: Backfill with soil or sand in layers, compact gently to avoid damaging the geomembrane.
