Flexible · Cost-effective · Quick install
PVC geomembrane for ponds, steel reservoirs and smaller dams where flexibility, handling ease and value per square metre are priorities.
PVC DAM LINING
PVC dam linings suit selected ponds, steel tanks and smaller water-retaining applications where flexibility and practical handling matter.
WHY IT MATTERS
Flexible sheet conforms to irregular pond shapes
Lower cost per m² on smaller surface areas
Common choice for steel tank and pond lining
Heat-welded or adhesive seams on prepared substrates
10–15 year typical service life with correct installation (conditions apply)
Compatible with many agricultural water uses
TECHNICAL DETAIL
MORE DETAIL
PVC excels on compact sites: lined steel reservoirs, nursery ponds, estate water features and farm dams under roughly 2 000 m² where crews can handle lighter rolls. It is also used inside corrugated tanks as the standard 850 gsm lining included on Damtech steel reservoir builds.
For large earth dams with rocky subgrades or heavy UV exposure, we usually recommend HDPE instead — see our HDPE dam lining page for comparison.
MORE DETAIL
Subgrade preparation matches HDPE projects: smooth, debris-free and compacted surfaces. Seams are welded or bonded per manufacturer spec; penetrations and crest anchors are sealed before fill. We advise on cover soil or shade where long-term UV exposure would otherwise shorten liner life.

FAQ
PVC suits smaller ponds, steel tanks and cement reservoirs where flexibility matters and puncture loads are moderate. Large farm or mining earth dams usually warrant HDPE for puncture and UV performance.
Damtech steel reservoirs include an 850 gsm PVC liner and bidem floor sheet as standard. Tell us if water is for human consumption so we can confirm suitability.
Yes, provided the pond can be drained and the base prepared. We assess slope stability and outlet details before quoting.
