Frequently Asked Questions

How do I find out the cost?

Use the Request a Quote form on this page and enter your pond dimensions. The quote is sent to you by email.

Are box welded liners suitable for Koi ponds?

Yes. Because the sides are vertical, the full depth carries across the whole pond rather than shallowing near the edges as a natural pond does. The manufacturer also states that the material is certified as non-toxic and will not affect Koi, other aquatic life or plants.

Will the liner become brittle in frost or sunlight?

The manufacturer states that the EPDM is unaffected by UV, temperature changes or frost, and that it will not become brittle or crack.

Can I cancel my order?

Because each liner is made to measure, an order can be cancelled before manufacture starts but not once manufacture has begun.

Is there a size limit?

There is effectively no standard maximum size. Each liner is made to your measurements.

Can the flange be a different width?

Yes. Other flange widths can be produced, with a minimum width set by the manufacturer. Tell us the width you need when you send your dimensions.

Each liner is box welded to the shape of your pond, so you get a neat finish with no folds or creases to hide once it is in place. It suits formal, ornamental, swimming and Koi ponds with vertical sides and a flat base. Send your pond dimensions through the Request a Quote form to receive a quote by email.

This is a made-to-measure pond liner, box welded to the shape of your pond, so it avoids the folds and creases of a flat sheet liner. It gives a clean finish with nothing to hide once the liner is in place. It suits formal, ornamental, swimming and Koi ponds with vertical sides and a flat base.

Each liner is prefabricated to your dimensions. Once unfolded, it slips snugly into the pond, which the manufacturer describes as quick and easy to install. The seams are fused by heat during manufacture, which the manufacturer says gives maximum strength and endurance.

The material is SealEco EPDM. The manufacturer states that it has been certified as non-toxic, so it will not affect Koi, other aquatic life or plants. The manufacturer also says it is unaffected by UV, temperature changes or frost, and will not become brittle or crack.

Because the sides are vertical, the full depth carries across the whole pond rather than shallowing near the edges as a natural pond does. That suits Koi and other larger fish.

The top of the liner has a flange that can be laid under paving flags to secure it. Other flange widths can be produced to suit your paving.
