Yes.... Leaking concrete ponds, preformed liners, rubber pond liners, plastic liners and clay lined ponds can all be repaired. Whilst leaking rubber and plastic liners can be fixed I would normally recommend replacing them especially if they are a few years old.
I have included some easy to follow DIY instructions on this page.
This works for rubber pond Liners, ponds made from clay and concrete lined ponds.
In the warmer summer months you will get some water loss due to evaporation and splashing from water features like fountains and waterfalls. However, once you have discounted this and have a significant or sudden loss of water you will need to find the leak.
To check the leak is actually from the pond and not the stream or waterfall or more likely the plumbing. Follow the steps below to find the leak.
Checking the main pond for leaks.
Turn the pump off, if the water level continues to drop the leak is almost certainly from the pond and not the plumbing or water-features so skip the full plumbing/water-feature check outlined below, (it may be worth a partial check of the plumbing/water-feature with the pump on once you have fixed the leak in the pond just to be sure). Providing the level isn't dangerous to fish, (plants will survive a couple of days without water) allow the pond to continue to leak until it stops and mark the level all around the pond with chalk.
When the water level has stopped look closely all around the chalk line for any damage.
Now check the plumbing and water-features.
The simplest way of finding the leak from the pond. This applies to all types of pond liners. Is to let the water settle to its own level, which will be just on or slightly below the leak and mark the level all around the pond with chalk. Look closely all around the chalk line for any damage to the pond liner.
Now that you have traced the leak let's look at the different ways and equipment you can use to fix the leak. Leaks in rubber and plastic are mostly about patching with waterproof materials whilst concrete and clay liners are more about filling and blocking the leak. We will look at these one by one in this article, Starting with fixing leaks in rubber liners.

How it works. The granules swell up to eighteen times its dry size when it becomes wet and forms an impermeable gel seal which makes an excellent pond sealant.

When properly applied it is environmentally safe and does not affect the water, fish or pondlife. Also makes an excellent liner for new clay pond construction.

Repair kit for all leaking concrete lined water-features including garden ponds, streams, waterfalls and bird baths.
It seals leaks in concrete ponds by forming A Non-Porous Seal
I recently fixed a clients leaking waterfall with this, the water feature was losing 4-6 inch's of water everyday, it took 3 coats and completely stopped the leak.
I have also applied it by pouring directly into a clean and dry pond and then spreading it and painting it around with a brush.
But I recommend following the full set of instructions that come with it. Mike
