Ponds are rarely framed in wood, but some older designs require a wood frame to stabilize loose soil around the edges. Installing a dock or other bank feature also generally requires attaching the pond liner to the new wood fixtures. Timbers are often stacked to create the sides of raised ponds and fountains too for unique water features that don’t require excavation. Pond liner materials like RPE and RPP are hard to adhere securely to wood with adhesive alone. Attachment bars are available that suspend the liner by the edges of the material and hold it tense over the wood supports. This ensures that the liner doesn’t slip or move, even after years of exposure.
Termination bars are usually sold for attaching flexible liners to concrete. However, they also work equally well for pond designs with wood edges and supports. Holes in the metal bars allow fasteners to pass through the liner and the backing wood or other material. Liner stays right where its installed with no adhesives to fail over time. The metal bars are treated to ensure they don’t corrode under constant water exposure from installation at the edges of the pond.
