How do I know the size pond liner I need?

Now the pond liner is more and more popular,it is widely used for fish pond, shrimp pond, water reservoir, dam, landfill, water treatment, oil gas and many civil engineering projects. It is waterproof,impermeable, and uv resistant.

Our company is a manufacturer of pond liner for more than 10years, with the ISO quality control system, use the 100%virgin raw material, the products property meet the ASTM ISO standard, and have third party test report.The clients are satisfied with the products quality very well.

To build a water pond, some client donot know the pond liner size, and do not know how to weld the pond liner.If the pond liner is too big, that will be a waste, but if too small, it is also a cost waste and time waste. This article purpose is to help customer to calculate the pond liner size for you ponds.

First step, measure your pond

You should measure the pond length, width, and depth.The size of longest length, and widest width,and also the deepest depth.that is a big size for the pond.

To weld the pond liner together, the welding machines will have a overlay or overlap,the overlap quantity is based on the laying method, and normally the overlap width is 15cm for reference.

Another item is about the laying, we should have extra liner for anchoring,we normally suggest to add 0.5m -1m to fix the pond liner.

Finally,With the size of pond and overlap, we could calculate the pond liner size, for example:

If you have longest length is 10m, widest width is 5m, and depth 2m, the pond liner size is

10length+2depth+2depth+0.5overlap+0.5overlap=15m long

5width+2depth+2depth+0.5overlap+0.5overlap=10m width

So the pond liner would be 15*10=150sqm.

Another easy way to calculate is a rough calculation, for the last example, the pond liner size is


Considering the overlap, the final size is 140*1.1=154sqm.

By the way, our engineers have many project experience, and can help with you with the pond liner size, and the best solution to reduce waste.
