Pond liners help and advice

Protect your pond from leaking and draining

A pond liner and underlay can make or break a pond. With the right liner, you can ensure your pond is protected from punctures and leaks and with a bad liner you're unlikely to have a pond at all. Our range of high-quality liners at Swell UK includes a wide selection of products from top brands, such as Gordon Low as well as our own outstanding range.

What are pond liners?

Pond liners are large supple pieces of material designed to act as a foundation for a pond, filling the hole dug to keep dirt out and water in. Importantly, pond liners aren't indestructible and must be teamed with the correct underlay to ensure that they aren't punctured or damaged by sharp roots and rocks.

Why should I buy pond liners?

Pond liners are critical for any pond project, if you try to fill a hole without a liner your pond will drain in a matter of days and be filled with all sorts of matter from the earth. Pond liners are designed to last against sun damage too, unlike bin bags or other materials, so you can be certain that your pond will withstand years outdoors without any degradation.

What are the main types of pond liners?

We stock six types of pond liners; Swell pond liners, PVC pond liners, pond liner underlay, pond edging, rubber pond liners and liner repair. Swell pond liners are made up of our own pond liners, many of which come with free underlay and lengthy guarantees. PVC pond liners are slightly tougher and more durable liners. Pond liner underlay is thick material placed under a liner to protect it. Pond edging is a decorative material that sits on the shoreline of your pond. Rubber pond liners are the toughest and most durable pond lines. Finally, liner repair includes tape and adhesives to quickly stop or fully repair tears and punctures.

What should I look for?

Once you have an idea of the sort of material you're looking for, all you really need to do is find a pond liner of the right size. We have a wide variety of pond liners at Swell UK and a helpful Pond Liner Calculator to help you find the perfect one.
