What is a Box-Welded Pond Liner?
Tuesday, May 07, 2013
A box-welded pond liner
is a prefabricated liner made to the dimensions of a pond construction so that it fits exactly to the size and shape with no folds or creases as with the installation of flat-sheet pond liners. It is highly recommended to add an over-lay of 'flange' when providing all the dimensions to secure the liner in place once your pond is filled with water using a choice of edging materials.
RDL make box-welded liners for simple rectangular or square-shaped ponds through to more complex bespoke designs such as those which require shelves, steps and L-shapes. In the majority of cases EPDM is used and manipulated into many shapes and sizes. Occasionally Butyl is used. The unique elasticity properties of rubber membranes make it the best choice for water containment projects such as the lining of ponds. Rubber is unaffected by UV light and temperature extremes, resists compressive loads and movements in the ground, free of plasticisers or other additives that can be leached out so will not shrink or go brittle.
Box-welded pond liners are fabricated to line vertically sided earth, brick or concrete formal shaped ponds. This type of pond liner is becoming more and more popular versus flat sheet pond liners or prefabricated ponds. If you are planning to install a tailored-to-fit liner, we recommend you first supply us with drawings and dimensions of exactly what is required so that we can work with you in fabricating an exact fit pond liner.
