How to choose correct geomembrane for your project?
Many engineers only know HDPE geomembrane, while there are multiple material options for anti‑seepage liner works.
Material types
✅ HDPE — GH‑1 / GH‑2S / GH‑2T1 / GH‑2T2
High strength & chemical resistance. Best choice for landfill, tailings pond, biogas and chemical containment.
✅ LDPE (GL‑1)
Soft, low‑cost, great low temperature performance. Suitable for small ponds, landscape water and irrigation channels.
✅ LLDPE (GL‑2)
Superior ductility, high elongation, ideal for sites with soft foundation settlement.
✅ EVA & ECB (Waterproof board)
Tunnel & underground engineering, excellent low‑temperature or dimension stability.
✅ PVC
Low cost for temporary works. ⚠️ Plasticizer migration problem, not suitable for high‑temperature liquid storage.
Surface options
- Smooth: general pond bottom
- Single textured GH‑2T1: slope anti‑slip
- Double textured GH‑2T2: steep slope / heavy surcharge
- Studded / point textured: anti‑slip, specifications to be agreed in contract
Climate selection tips
❄️ Cold area: GH‑2S for hazardous waste / landfill; LDPE & LLDPE for aquaculture & irrigation
☀️ Hot sunny site: check thermal aging & OIT value, carbon black content 2.0~2.8%
🌡️ Large temperature swing: reserve expansion space, do NOT stretch liner tight
Do you pick wrong geomembrane material? Even genuine geomembrane will slide or fail if wrong grade selected.
