PLEASE NOTE: Because we are an outdoor facility, your liner may arrive with some minor dirt/dust markings from rain splashing, however we guarantee it is brand new and never used!
To determine the size of liner and underlayment needed for your project, use the following formulas:
(Max Length of Pond) + (2 x Max Depth of Pond)) + 1 = Length of Liner/Underlayment Needed
(Max Width of Pond) + (2 x Max Depth of Pond)) + 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.
