Box-Welded Pond Liners

A box-welded liner is a prefabricated 3D pond liner made to your exact dimensions to fit like a glove into your pond construction. There are no folds or site seaming required during installation. All of the seams are fully overlapping factory welds (hot bond vulcanised) for maximum strength.

Fabricated in our factory to your dimensions, sketch or technical drawing.

Pond Liner Estimator

If you are yet to dig your pond, or are unable to measure it with a flexible tape measure, or simply just planning a pond, then use our simple Pond Liner Calculator to estimate the sheet size required for your pond.

How to use this pond liner calculator :-

Simply enter your ponds longest length, widest width and maximum depth dimensions (in Metres) in the relevant boxes below and the calculator will show an estimate of the pond volume in Litres and pond liner size required, which you may use as a guide to help with selecting filtration equipment and fish stocking levels.

For example a proposed pond with maximum length of 6m, a maxium width of 4m and maximum depth of 1m will require a Pond Liner 9m x 7m and have a maximum volume of 24,000 litres.

Pond Estimator


The Pond Liner Estimator will automatically add 0.5m to both the length and width as an overlap to secure the liner. This allowance (25cm on each edge) may be reduced if securing under brickwork, or extended for a bog garden edging or beach.

Please note:- we strongly recommend you only use these calculations as part of your project planning exercise and strongly advise measuring the final excavated pond profile and overlap (edge dig in) required with a flexible tape measure prior to purchasing the liner. We would always recommend obtaining professional advice regarding pond size and water volume in relation to the end use, be it a wildlife or fish pond (i.e. minimum depth to avoid freezing, the number and size of fish you can have, etc.).

Now you know what size liner you need, whats next? Choose a pond liner type (rubber or pvc) and where to go to get the best deal!
