Rubber Pond Liners

What are rubber pond liners?

When it comes to selecting a pond liner to serve as the foundation of your garden pond, you can't go wrong with a rubber pond liner. These flexible yet durable garden pond liners are widely considered the best type of pond liner available. Most rubber liners are made are made from EPDM (ethylene propylene diene monomer), a synthetic rubber material.

Why are rubber pond liners considered the best?

EPDM is strong and supple, making for garden pond liners that are not only incredibly easy to install, but built to stand the test of time too. EPDM doesn’t expand or contract at high/low temperatures either, so temperature differences won’t cause it to lose its grip on your ground’s surface.

Despite their softness, EPDM pond liners are incredibly resistant to punctures, UV rays, and general wear and tear. They’re only let down by the fact that they can be quite pricey, but you do get what you pay for – high-quality fish pond liners that are well-suited for both small and large custom ponds!

What are butyl rubber pond liners?

EPDM isn’t the only type of synthetic rubber material used in some garden pond liners, there’s butyl too. For a long time, butyl rubber pond liners were the most widely used type of fish pond liners in the UK, thanks to their highly flexible, easy-to-mould nature. That said, butyl rubber pond liners aren’t quite as durable as EPDM pond liners and are, as a result, a little more susceptible to general wear and tear.

What other types of pond liner are available?

While EPDM and butyl rubber liners are considered the best types of pond liner that money can buy, they're not the only types of pond liner available. There are several different types of garden pond liners out there, including HDPE pond liners and PVC pond liners. We sell both HDPE pond liners and PVC pond liners, in varying sizes and with differing guarantees. Check out our PVC pond liners to learn about the pros and cons of each pond liner material.

There are many sizes of garden pond liners to choose from, from small pond liners suitable for tiny nature-style ponds, to big pond liners suitable for large ornamental ponds full of fish, like Koi ponds. A large pond liner is often called a lake liner, because of its size. These are typically heavy duty liners designed to cover huge outdoor spaces, often in excess of 20m².

Not all garden ponds have pond liner foundations; some, like preformed ponds, rely on a plastic/carbon-fibre basin to retain pond water. These kinds of ponds may be attractive to new pond keepers for their simplicity, but they don't offer the amazing flexibility that pond liners do. They're also limited by their shape and size, with a maximum depth that cannot be changed. This rules out the use of some pond pumps, pond filters, and water features.
