What size do you need?
To determine the size of liner and underlayment needed for your project, use the following formulas:
(Max Length of Pond in Feet) + (2 x Max Depth of Pond in Feet) + 1 = Length of Liner/Underlayment Needed.
(Max Width of Pond in Feet) + (2 x Max Depth of Pond in Feet) + 1 = Width of Liner/Underlayment Needed.
It is always a good idea to have an additional foot of material on both the length and width of the liner and underlayment (represented by + 1 in the formulas). This allows room for error and also provides an overhang to secure the materials properly.
