POND LINERS

Pond Liners are the most versatile and adaptable materials for pond construction. They are easy to store and transport, and are almost unlimited in size and pond shape.

They do require care and forethought to install, but will yield the best results. Liner is susceptible to puncture or physical damage, so care is needed in installation and we advise using protective underlays and overlays.


Various installation and edge methods are shown below. Always ensure there are no stress points (stretch points) and no direct sunlight exposure as the guarantee does not include UV degradation.

Joining Liner: Liners can be joined on site with tape or glue. This requires a medium level of skill and if care is not taken, could result in leaks. Factory welds are recommended for submerged joins and long seams. Folds and creases are preferable to cutting and joining.

Pond Liner Size Formula:    Width: maximum pond width + (2 x max. depth) + (2 x edge allowance)
                                                  Length: maximum pond length + (2 x max. depth) + (2 x edge allowance)
Example:  For a pond that is 4m x 3m, 0.5m deep at deepest point and 400mm edge allowance:
                                                  Width: 3m + (2 x 0.5 = 1) + (2 x 0.4 = 0.8) = 4.8m wide
                                                  Length: 4m + (2 x 0.5 = 1) + (2 x 0.4 = 0.8) = 5.8m long
Therefore, you would order a pond liner 5m x 6m (liner is sold in whole metres only)  and underlay 2m wide x 15m (to be cut into 3 pieces, each 5m long).
