Pond Liners:

• 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 above.
• Always ensure there are no stress points (stretch points) and no direct sunlight exposure as the guarantee does not include UV degradation.
• If protected from the sun, liner should last 30+ years.

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)
