EPDM liner for shaped ponds, streams and reservoirs
Flexible EPDM liner forms the waterproof layer in a pond or water feature. The Aquascape range includes substantial sheet sizes for naturalistic excavations and larger reservoirs. Choose the sheet size from the finished ground profile, including the depth, shelves and edge allowance, then plan suitable protection beneath and around it.
Can I join two sheets?
Use the manufacturer’s specified EPDM seaming system and surface preparation. A joint is a deliberate installation detail, not simply an overlap held down by water.
Leave enough material for the real shape
A sheet covers the base, sides and margins, not just the top opening. Deeper areas and waterfall transitions use additional material. Measure the excavation once its shape is settled, allow for the final edge detail and avoid stretching the liner tightly across corners.
Handle large sheets as a planned operation
Large liner packs can be heavy and awkward. Check the selected sheet’s weight, delivery arrangements and route to the pond. Unfold it on a prepared, protected surface and keep sharp tools and footwear away from the material. Use extra protection where landscaping will bear on the liner.
When should I trim the edge?
Only after following the installation guidance and allowing the liner to settle into its final shape. Premature trimming can remove the material needed for a secure edge or later adjustment.
