A leaking pond liner in a koi pond can usually be patched if the damage is not too extensive. The first step is to locate the leak, which may require temporarily lowering the water level to reveal the puncture or tear. Once the leak is found, the liner surface must be cleaned and dried before applying a patch. Repair kits are available that match specific liner materials, such as RPE, EPDM, or PVC, and using the right kit for your liner type is important for a long-lasting seal.
Most patches involve adhesive-backed materials or glue that bond the patch securely to the liner. For small holes or minor damage, a well-applied patch can restore the liner’s integrity without needing a full replacement. It’s best to monitor the repair over time and check for any signs of continued leaking. If the liner is old or has multiple weak spots, patching may be only a temporary fix and replacing the liner might be more effective in the long run.
