Question by Jin R: can i use 2 pond liners for my water garden/pond?
I just want to make sure that my pond will not leak and that it will last a long time. Other than costs, are there any disadvantages of having 2 pond liners for a pond that is about 8 ft long x 5.3 ft wide by 2.5 ft deep?

    Before you buy the liners, check out a Roofing supplies store. The rubber “Ice Barrier” that they use on the lower edge of roofs may be thick enough to use instead of using 2 liners. It may be cheaper too.

    Which ever you use, when putting in the stone, use the type of stone that is smooth. Like beach stones. Don’t use “fractured” stone. Fractured stone has sharp edges and if you step on that stone while working on the pond, you may cut the liner/s and than you’ll have leaks.

    No, that doesn’t work. If the liner is not thick enough, it will fail. The second one usually fails at the same time. Even if it doesn’t water gets between the two and soon the upper one is floating at the water’s surface. Use a 40 mil butyl liner that comes with at least a 20 year warranty.
