I have a huge problem with the liner of my pool pulling away from the corner of the deep end, as well as under the skimmer. The pool has a layer of foam between the liner and the concrete walls that appears to be "bunched up" due to the amount of water behind the liner. We have had around 10" of hard rain in the past few days, and I know that the water table is high, as I can see the water behind the liner. At this point is has completely pulled away from the wall. After noticing the issue, i have made sure that the water level in the pool is above the 1/2 point of the skimmer, hoping that keeping the water high will help move it back into place. No such luck. I am wondering if it is possible to cut away the foam that has bunched up, and then be able to stretch the liner back into place? Since the foam has floated also, it would be almost impossible to stretch the liner over it to be put back in place. Any advice would be greatly appreciated!
