DIY Pond Liner Repair Tips

If you have a man-made pond in your backyard, it is important that you keep an eye on the pond to make sure everything is working properly. It can be a terrible feeling to come out to your pond one day and find that most or all of the water has been drained away because of a leak. If you have water plants and fish in the pond, a severe leak could even kill them. Fortunately, if you are vigilant, you can notice these leaks early on and have them fixed. In fact, most people can take care of these repairs on their own without much trouble at all. The following are some DIY pond liner repair tips that can help you keep your pond in great working condition.

Find the Leak

The first step is to find the source of the leak. While all leaks can be problematic, if you are fortunate, the only issue is having a liner that has slipped. This means that part of the liner has been dislocated from its original position and has slipped into the pond, which will be the source of the leak. If that’s the case, you can generally just move the liner back in place, secure it, and fill the pond back up with water.

However, you might not be so lucky. If the liner did not slip, and there is not an issue with the pump, it likely means there is a hole or tear somewhere in the liner. In this case, remove any plants or fish from the pond and keep them somewhere safe. Try to keep them in the water from the pond, so they do not have to try to acclimate to a completely new environment.

Once you have removed them from the pond, refill it with water, and then wait for the leaks to stop. The hole will generally be right near the water level and/or above this point. You need to closely inspect the liner to look for any holes and tears.


DIY pond liner repairs for holes and tears will utilize patches made from liner material, along with pool liner sealant. You need to clean the area of the holes to make sure there is no debris left behind, and then you can add the patch and cover it with the sealant. Make sure you get all of the holes by double-checking the liner for other issues. Once the patches are dry, you can then replace the liner into the pond and fill it with water.

Check for More Leaks

After the water has been returned to the pond, it doesn’t mean your search for leaks is over. You need to make sure the water stays at the appropriate level, and that the patches are holding, before you return your plants and fish.

Keep Vigilant

As you can see, DIY pond liner repair is possible, and it tends to be simple, but potentially time-consuming. Keep a close watch on your pond to make sure you catch any future issues as early as possible.
