Quality Box Welded Pond Liner

Our box welded liners are the perfect solution for formal, ornamental, swimming or Koi ponds where the sides of the pond are vertical and the base flat. Every one of our box welded liners is prefabricated in our factory, to your bespoke requirements. Known as fish pond liners, box welded to individual shapes, a box pond liner can be the perfect solution for your pond in your garden. 

Why should I choose a made to measure, bespoke liner?

For formal ponds, either above or below ground, a tailor-made pond liner will fit the exact dimensions of your pond. When the liner is delivered to you, you simply unfold it and slip it snugly into place, it’s very quick and easy to install. A simple fish pond liner alternative to the standard liner.

Once in the pond, box welded liners do not have any unsightly folds or creases that need to be hidden as you would get if using a flat sheet liner. Box welded pond liners are also manufactured with a flange around the top that can be laid under paving flags to secure the top of the liner.

All our tailored liners are made in 1.00mm SealEco EPDM and heat welded (vulcanised) in our factory to ensure maximum strength and endurance of the liner.

Are box welded liners suitable for Koi ponds?

Yes! We have completed many Koi pond lining installations in the past (even with some Koi farms) using a box weld liner. Using a bespoke liner in a formal shaped pond provides the perfect habitat for Koi and other larger fish varieties because the whole area of the pond has a greater depth compared to a natural pond which will get shallower near the edges.

The SealEco EPDM that we use for all our made to measure liners is certified non-toxic so will have no impact on any Koi, other aquatic life or plants you choose to put in your pond. It is also unaffected by UV, temperature fluctuations or frost so you can be safe in the knowledge that your liner won’t become brittle or crack.
