What is the Swell HDPE Pond Liner lifetime With Underlay?

The Swell HDPE Pond Liner Lifetime With Underlay combines our most popular pond liner and underlay with an unequalled lifetime guarantee. Our liner is designed to be laid over the thick material of the underlay to create a barrier to protect your pond from punctures and leaks. The liner itself is made from 0.35mm-thick HDPE with a UV-resistant coating - for unbeatable durability. We offer this liner set with a lifetime guarantee so you can be sure the liner will withstand the test of time.

Is it hard to lay this pond liner?

Not at all, HDPE pond liners are quite supple, making installation easy. Unlike flexible pond liners, such as rubber pond liners and PVC pond liners, HDPE gently moulds to the shape of your pond. This means that no matter what shape your garden pond is, our liner will fit it, from wildlife ponds to Koi ponds.

How much pond liner will I need?

If you're unsure of the amount of Pond Liner to buy you can use our Pond Liner Calculator to find the right length and width of liner for your pond. We'll even match the size of your pond lining with an appropriate pond liner underlay, so there's no need to worry about matching your liner and underlay.

What does the guarantee cover?

This Swell Pond Liner With Swell Pond Liner Underlay carries a lifetime guarantee. As with all garden pond liners sold in the UK, the guarantee covers UV damage only, not punctures.
