What are these pond liners?

These Gordon Low SealEco Greenseal EPDM Pond Liners are synthetically fabricated, flexible pond liners made from a specially blended, 0.75mm-thick rubber material. This material, EPDM (ethylene propylene diene monomer), is made in Sweden by pond and lake liner specialists SealEco.

It's widely considered one of the best types of pond liner material available, thanks to its durability and resistance against UV radiation, chemicals, and temperature extremes. To make this material suitable for use in garden ponds, it's cured under high pressure and heat to create an elastic and chemically stable product.

No matter the size of your garden pond there's a pond liner to suit your needs. Just select the right size pond liner for your pond using the handy dropdown menu at the top of the page. We stock over 40 different sizes of pond liner, from small pond liners measuring 3x5m to big pond liners measuring 14x20m. 

What size pond liner do I need?

Selecting the right pond liner for your garden pond is usually quite tough, but with our handy pond liner calculator tool it's made quick and easy. Just measure your pond's length, width, and depth, and input the details into the pond liner calculator.

After a speedy calculation it'll tell you how much pond water your pond will hold and the minimum size pond liner you'll need to sufficiently cover the base of your pond. It'll also tell you the minimum size protective underlay you'll need, should you want that added protection.

Are these pond liners easy to fit?

At 0.75mm thick, these rubber pond liners are thicker than cheaper PVC pond liners or HDPE pond liners, and they have a much softer, more supple texture. This flexible quality makes these garden pond liners easy to fit, particularly in a wildlife pond or sculpted garden ponds like Koi ponds.

How durable are these pond liners?

These heavy duty liners are built to last and designed to support your garden pond for years. In fact, we're so confident in the durability of these fish pond liners, and the EPDM they're made of, that we've given them a lifetime guarantee.

For added peace of mind, though, you can choose to purchase one of these garden pond liners with protective underlay fit to size. This Gordon Low Pond Grade Underlay is a high quality pond liner underlay, designed to protect your pond liner from sharp stones and reduce the likelihood of leaks.

What does the lifetime guarantee on these pond liners cover?

These fish pond liners come with a market-leading lifetime guarantee. As with all pond liner guarantees, this lifetime guarantee covers damage from frost and sunlight. It doesn't, however, cover damage from punctures so it's highly recommended that you purchase a puncture-resistant layer of protective underlay to sit underneath your pond liner.

These rubber pond liners, like other pond liners, are UV resistant. This greatly reduces the risk of UV damage from sunlight, provided your pond liner is well cared for.

Please note:

Large pond liners and pond underlay will be delivered on a pallet for protection in transit. Delivery time is also an estimate and not guaranteed.
