Pond Liners – Should I buy preformed or flexible pond liner?

Do I choose a preformed pond, or just buy pond liner?

Pond liners are basically of two types, flexible and preformed pond liners depending on the size of your pond. The flexible liners are made up of rubber which is fish-friendly and could last up to two decades. This type of liners are good for large ponds as they might be too thick to fit in a small pond. The preformed liners come in shapes that are already formed making it a perfect form for small ponds, these will save your time from putting patches yourself and are long lasting as well! There a few different forms of liners, butyl pond liners, rigid, rubber and small plastic liners.

Lay your own flexible pond liner. 

Pond liners serve as the foundation for your pond and just like every foundation, these need to be of reliable material. No doubt that they are the heroes of your pond as they make sure that the water stays in the pond instead of draining to the surroundings. The tough material is laid down at the bottom of the pond, usually on sand so that external factors won’t destroy the liner. By now, you must have had an idea of how important it is to buy a good liner first time, don’t skimp here! However, you don’t always need liners. Pond liners are required when the design is now shallow enough to use soil as liners in order to compact the soil. If the pond is shallow enough then professionals could be brought in to use soil as the liners, although it is a complicated process. Before finalising a liner for your pond, you should be sure of the size of your pond so that the thickness of the liner could be finalised accordingly. Read More About Flexible Pond Liners Here

Preventing damage to the flexible pond liner

Cleaning the space before installation helps in eliminating the chances of damage to the liner by sharp objects that might be present in the space. A layer of sand (or even smooth concrete) before installing the liners will protect it from any such damage. These steps are important since you are already spending good money on a decent liner, so you need to make sure that they remain protected for a long period of time.

There are different styles, materials, and designs available, and each has its advantages and disadvantages.

One of the first choices you will need to make is whether you want a flexible liner, a preformed liner, or a concrete floor. Flexible liners are the least expensive and can be custom cut to fit any shape you want. However, they require careful measuring and cutting to avoid wasting material.

Preformed liners, on the other hand, are made of hardened plastic or rubber material and come in predetermined shapes. They are simple to install and relatively inexpensive but offer less design flexibility.

For a longer-lasting option, you may want to consider a concrete floor. While it can last a lifetime without cracking or leaking, it is more expensive and requires professional installation.

Finally, you should also consider the material of your liner. Each has its pros and cons, so it is important to weigh them carefully before making a decision. Overall, choosing the right liner is crucial to ensure the longevity and success of your pond.
