:I just figure that they will tear the liner at certain areas and that a clay substrate beneath the most likely weak spots will help insure that tears won't drain the pond. They say that you can make clay bottomed ponds that will hold water ========================== That's true, but if you get a leak, and the clay bottom seals the water underneath it, the water pressure will be the same on both sides of the liner. The liner will float up away from the bottom where ever it is not held down by rocks or logs. Been there done that, trying to use 3 layers of cheap plastic to line a small pond, the tear or hole happened near the water fall, which forced bubbles between the layers.
