4 Different Ways To Repair A Pond Leak

Pond Liner Sealant (very small tears/holes)

This method is great for tears or holes 1-2 inches wide. It’s also a great product for leaking waterfalls and fountain heads. Pond leak sealants are also safe for fish, making them great for pond leak repair.

Here’s how to apply it:

  1. First, drain the pond to the leak area
  2. Dry the area around the leak
  3. Squirt the sealant directly onto the tear
  4. Wait around 8 hours for the sealant to expand and cure
  5. Finally, add in water, fish, and plants.

  • Easy to use
  • Not expensive

Pond Liner Repair Kits (small to medium tears/holes)

It’s like patching a hole in clothing, but this is to stop a leak. Most come with primer, a self-sticking patch, and a roller. The patches mostly range in size from 2″ x 2″ – 30″ x 30″ (it’s better to go a little bigger than you think you need).

Here’s how to use it:

  1. First, drain the water to below the hole and dry the area around it.
  2. Apply the primer to clean and prepare the area for the patch.
  3. Cut the patch in a circle (square cuts can fray at the corners over time).
  4. Apply the patch firmly and use the roller to remove any air.
  5. Finally, wait a few minutes for it to set and then refill your pond.


  • Comes with all necessary parts
  • Easy to use
  • Blends in well


  • Not good for large damages

Pond Liner Joining Tape (for adding extra liner)

Sometimes the problem is you need more liner. Joining tape allows you to attach more liner and can be used for very small tears and holes.

The joining tape is sticky on both sides for maximum effectiveness, but this also means it can’t get it wet or dirty.

Here’s how you use joining tape:

  1. Make sure liner is clean and dry
  2. Prime it with liquid primer ana d scrubbing brush
  3. Use the double-sided joining tape to stick them together
  4. After a few hours, it is water resistant and ready to go


  • Great for extending the liner
  • Good for very small tears and holes
  • Good for resealing pond skimmer boxes


  • Not good for large damages
  • Needs dry liner to work
  • Can be difficult to prepare

Replace The Pond Liner (for when repair isn’t possible)

This is a big step, but it can be a necessary one. Replacing the liner with high-quality liner can stop any current leaks and help keep future ones from occurring.

Here’s a basic overview of how it would work:

  1. The pond is drained and cleared of everything
  2. The liner is removed
  3. The new liner is laid in
  4. The pond is put back together

This is a simplified version of what would happen, the real deal could take several hours and a few people. It all depends on the size and scope of the project.


  • Repairs any and all liner damage
  • A high-quality liner can last for years
  • Best solution for large tears or multiple holes


  • Most expensive option
  • Requires lots of time and effort
  • May have to hire a contractor
