What Affects Pond Liner Price?
-
Material — rubber (EPDM/butyl) costs more than polyethylene (HDPE/LDPE/PVC) but lasts longer
-
Thickness — 1.02mm EPDM costs more than 0.75mm but delivers 35% more material and a longer guarantee
-
Size — price scales roughly with area; larger liners offer better m² value
-
Underlay — always budget for underlay (same size as liner); adds 30-50% to liner cost but is essential
