They also installed some sort of gas vents around the perimeter of our 1 acre pond.
We have had problems with water coming up under the liner,when the pond is empty, sometimes 10-12" worth: sort of like walking on a REAL big water bed, mostly because we have another 1 acre pond nearby, at a slightly higher elevation,and it's a bad leaker.
But as soon as we fill the lined pond, the weight of the water takes care of the bottom bulge.
