Doubling a pond liner

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?

Answer:


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.
