Box-welded pond liners are better suited to some pond builds especially regular shaped ones where a 2-dimensional pond liner installation will result in unsightly folds and creases. A box-welded pond liner is cut and fabricated or hot bond welded to the dimensions and design submitted by the customer. An overlay lip is included upon which flagstone or other edging material can be placed to secure the box-welded liner in place. The pond liner is then slipped into the pond dug-out – and above a sheet of Geotextile protective underlay liner. The result is a perfect fit to a formal pond.

Vertically sided ponds create a splendid feature in any garden and are often home to Koi-fish. Liners Online have the expertise to cater for ponds from simple designs to more complicated ones – including those with planting shelves, sloping bases, uneven depths or a haunched base to fit a bottom drain. For very sophisticated designs, the box-welded pond liner can be welded onsite.

Box-welded pond liners are also referred to as custom-made, tailored-to-fit, bespoke or made-to-measure liners. Butyl and Epalyn (EPDM) pond liners are a synthetic rubber material from which a box-welded liner is made. To assist in providing a box welded pond liner, a drawing is needed showing all the dimensions.
