Industrial sewage ponds contain acids, solvents and heavy metals demanding chemical resistance; concrete tanks need reliable liner fixing and dozens of pipe details — one failed detail leaks.
Sewage Pond Lining: Sewage ponds use 1.0-1.5mm HDPE (GH-2 environmental grade), uprated to 1.5-2.0mm with GCL-OF double liner for aggressive streams. On concrete tanks: dress and level walls, geotextile cushion, lay and weld membrane, fix crest with pressure strips and anchors plus sealant, reinforce every pipe/corner with extrusion weld and double patches, vacuum-test details, air-test seams, then run a closed-water test.

| Location | Recommended material | Reason |
|---|---|---|
| Liner | 1.0-1.5mm HDPE GH-2 grade | Chemical & biological resistance |
| Aggressive duty | 1.5-2.0mm + GCL-OF double liner | Detection layer between |
| Cushion | 200-400 g/m² geotextile | Concrete surface protection |
| Fixings | Pressure strips + anchors + sealant | Crest and wall fixation |
| Details | Same-material patches + extrusion rods | Pipes, corners, joints |
2024Concrete tanks lined with 1.5mm GH-2 HDPE over geotextile cushion; crest pressure strips with anchors and sealant; all boots and corners extrusion-welded with double patches and vacuum-tested; closed-water test passed.
View project details ›Three keys: clean level substrate, 100% tested seams, and double-patch extrusion-welded details with vacuum tests. Crest fixing and sealant continuity complete the system.
Only with sufficient confining pressure to hydrate; on bare concrete HDPE remains the primary liner, GCL suits composite double-liner designs.
