Identifying the Leak
Before you can fix a leaking pond liner, you need to locate the source of the leak. Follow these steps:
- Check the Water Level: Monitor the water level in your pond over a few days. If you notice a significant drop, there’s likely a leak.
- Inspect the Edges: Look around the edges of the pond where the liner meets the ground. This is a common area for leaks.
- Use a Dye Test: Add a few drops of food coloring near suspected areas. If the dye is drawn into the liner, you’ve found your leak.

Step-by-Step Instructions
Step 1: Drain the Pond
Carefully drain the pond to expose the liner. Make sure to save as much water as possible to refill later.
Step 2: Clean the Area
Use a scrub brush to clean the area around the leak. Remove any debris, algae, or dirt that could interfere with the adhesive.
Step 3: Cut the Patch
Cut a piece of the patch material that is at least 2 inches larger than the leak on all sides.
Step 4: Apply Adhesive
Apply pond-safe adhesive to both the patch and the area surrounding the leak. Press the patch firmly into place.
Step 5: Allow to Cure
Let the adhesive cure as per the manufacturer’s instructions, usually 24 hours.

Once cured, refill the pond with water and monitor for any further leaks.
