So you have excavated a large hole in the garden in preparation for pond’s construction, now what? The next step is to somehow prevent the future water to seep into the ground, which would leave your pond empty and fish dead. What you need is a pond liner.
Pond liner is essentially a piece of waterproof fabric which will keep the water in place. As the name suggests, it’s used to line the dug hole. Not all liners are made equal though and today we will present you a guide how to choose the best pond liners. We will chip in a couple of pond liner reviews as well. You can find them at the bottom part of the article.
Types of pond liners
Pond liners are made of various materials which vary in strength, flexibility and of course price as well. Let’s take a look at the choices you have:
- PVC pond liners – PVC pond liners are usually around 0,5mm thick. The liner is stretchy, however it’s not tearproof, so if the material is punctured, it may get worse over time, eventually leaking all the water from the pond and causing you to get a new liner. Oase pond liner are some of the most popular PVC liners
- Rubber pond liners – These liners can be further divided into EPDM and Butyl Butyl has for long been considered one of the best materials for the pond enthusiasts. However due to high demand in many other industries, it has become quite expensive. EPDM, on the other hand, is less costly material and it has similar or even better characteristics than Butyl. Firestone is one of the most popular rubber liner brands worldwide.
- LDPE pond liners – These liners have two basic benefits – they are very economical, and they are tearproof and flexible. The liners are made of low density polypropylene and they are made to last for years.
- Preformed pond liners – As the name suggests, these liners are preformed and in most, their shape cannot be changed. Therefore if you go for such solution, you will not be able to adjust the pond’s shape in future, unless you’d dig the liner out.
Can you put a liner directly on the ground?
The simple answer would be “yes, you can, if you want to”. On the other hand it is not recommended at all. If you put the liner directly on the dug up ground, chances are there will be a sharp stone which will cause a puncture in the liner when you start pouting in the water.
To prevent such cases, pond liner underlays are available for purchase. Having the underlay under the liner will smooth out most of the sharp stones or rocks underneath the liner. So get yourself the underlay if you wish to have your pond intact for years to come.
Pond liner calculator
There’s not need to make things complicated when calculating the liner’s size. All you will need to do is measure the pond’s width length and depth and then do some simple math:
- Length + Depth + Depth +2 = Length of Liner
- Width + Depth + Depth + 2 = Width of Liner
