You might have seen the term thrown around somewhere before, but exactly what is a pond liner? In simple terms, a pond liner is an impermeable material that is used in the bottom part of a water body such as a fish pond, artificial river or lake to help with the retention of water. While some people will argue that a pond liner is expensive to install, its great benefits far outweighs the cons. A pond liner helps to prevent common problems such as pond leakage, erosion on artificial river beds, and even contamination.
Pond Liner Installation
Pond liners should not be placed on sharp objects during installation as this will only serve to puncture them and therefore leakage will occur. It is advisable to place it on a layer of sand that has been checked to be free of any sharp objects like stones or nails to avoid the possibility of puncturing it.
Benefits of a Pond Liner
- Prevent Erosion – ponds that have liners on them will not experience erosion that is often caused by heavy rainfall. This helps to maintain the shape and structure of the pond, while those without pond liners will experience erosion especially on the banks and consequently lose shape. The best types of pond liners to use on the bank of your pond are either the preformed or flexible liners. These help to stop erosion of the soil around the pond and thus helping maintain the shape of the pond.
- Prevent Leakage – of course this is often the main purpose of a pond liner to be used in a pond. A pond that lacks a liner often leaks too much and this way lots and lots of water is lost. As the water leaks, valuable minerals and salts such as magnesium, calcium, and compounds of selenium also go away with the leaking water. With water leaking away from the pond every minute the level of the pond water keeps on dropping and the water would regularly need to be replenished in the pond.
- Prevent Contaminants – when you put a liner in your pond before filling it with water there will no chance of the water mixing with the soil beneath the lining material. This way the water remains clear and pure of any contamination that could otherwise come from the soil below. This means that the water that will be in your pond remains pure and will be good for the plants or animals that you decide to put in the pond.
Even though it may take you some time and effort to finally have a pond that is well lined, the benefits of taking such a venture will be rewarding to you in the long run. You must also note that pond liners are made from various different materials with each having their pros and cons. It will be up to you to go for a pond liner made of a material that you feel will best suit your unique needs.
