Capillary barrier
One of the most annoying areas on the garden pond is the edge area. Here the pond liner must be led over the edge of the pond and through a small ditch and then buried. This is inevitable as a capillary barrier.

The purpose of the capillary barrier is that the surrounding soil does not simply “suck out” the pond through capillary action. This would inevitably be the case with unprotected pond edges and a pond liner only pulled up to under the pond edge.
The problem with this is that the film remains visible at this point - and that doesn't look pretty. Sprinkling the foil with gravel is an option, but in most cases not a particularly good one.
Embankment and embankment mats
These mats can simply be placed on the pond liner. They reach a little over the embankment and cover the foil very well in the edge area. This has several advantages:
- the pond liner is well protected from damaging solar radiation at the edge
- the foils allow the pond edge to be planted so that the edge of the pond looks completely inconspicuous at the end
- Embankment foils give different design materials (small plants, stones, moss) a good hold, so that they can be designed in a varied way.
In terms of price, the mats are quite reasonable - they are available in different widths between 60 cm and 2 m, and you have to calculate around 10 EUR for the running meter. A starter planting including suitable fertilizer is often included (flowers or moss). The flower solutions in particular often bloom very intensely and are usually very easy to care for.
You should be careful with coconut mats (116.09 € on Amazon *) or mats made of jute. While they're also a good solution, they often rot within a few years. Then they have to be removed because they also cause bad smells when rotting.
Stone foils
Stone foils are also a way of covering the pond liner in the bank area. They consist of a plastic mat covered with a small layer of stone. The steepness of the slope is irrelevant when using stone foils, they can be used on all types of slopes - whether flat or steep. The prices are about as high as the plant foils and sea mats.
Tips
You can also use stone sheeting to visually hide the pond liner in a stream and to better protect the pond liner. A complete lining of a pond interior with stone sheeting is usually unnecessary and usually also nonsensical.
