PVC Dam Liners
PVC geomembrane for ponds, steel reservoirs and smaller dams where flexibility, handling ease and value per square metre are priorities.
PVC liners are a practical choice for smaller farm ponds, ornamental dams, steel tank interiors and cement reservoirs where HDPE’s stiffness is unnecessary. Reinforced PVC at 550–850 gsm balances flexibility with tear resistance — well suited to sites with moderate UV exposure and controlled livestock access.

Where PVC Liners Work Best
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.
PVC Installation Approach
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.
