I have the beginnings of a large pond (pond is dug out with an "island" of hard dirt in the middle.) The question I have concerns the method of draping a liner over the island to line pond, and the resulting folds this produces. I was told that the folds would be very large and radiate out quite a ways and this was problematic because raccoons (which I have) might tear the liner at one of these vulnerable places, and that would be very difficult to repair. I suggested taping all the folds down but was told that would be prohibitively expensive due to cost of the tape ($4 per foot). I wonder if it is possible to skirt this problem by wrapping a length of liner around island, sealing edges with tape and then draping the large section of liner over island and cutting a large hole so that liner falls completely over island to the bottom of pond and then is joined all around the edges to the side of the island liner with tape... Any suggestions?
