Compare Pond Liners

What’s the best pond liner?


That depends on the type and size of the pond you are looking to create. You can read our guide to pond design in the help and guides section.

Below, we have put together a material comparison table showing the pond lining options available. It provides details on the composition of the materials and their features, sizes available, and the applications they are most suited to. For more information on any of the lining materials, you can click on them below and be taken to the respective product page.

We hope that the information helps you choose the best type of liner for your project. If you have any questions about any of our pond liners, please contact us and we’d be happy to help you.
