We just finished a rather extreme Canadian winter and our 2 year old pool has an issue that I am looking for advice with.
Attached are 2 pictures showing a bulge in the pool wall that appeared about 4" above the ground. This is visible around the entire pool. The bending of the uprights is only where the pool wall has pushed out and bent them. I do not believe this to be a snow load issue. The pool had less snow on it this year than last year. I was talking with a local pool supplier/installer and they mentioned that they know of about 30 pools with this same issue but would not provide any insight as to the cause. The pool was winterized as we have done in the past (and as I have helped do since I was a kid) - water was drained to just below the jet and a winter cover installed.
My first question is the cause of the damage. I am concerned that repairing or replacing the pool may be futile if the same damage occurs again next winter. Any ideas as to the source of the problem would be greatly appreciated.
Secondly, can this type of damage be repaired? I have spoken tot a few people who say just fill the pool and see if it holds. I'm pretty handy so I was considering disassembling the pool, pressing the pool wall as flat as possible and smoothing the bends in the uprights/replacing those that can not be fixed. Does anyone have experience with this sort of repair that they could share (other than the obvious amount of work that is involved)?
Thanks for any help that can be provided.
