Hi, new to the forum and just wanted to get some opinions on something.
We are currently having a fiberglass pool installed. I'll layout a brief timeline leading to where we are currently.
Our pool was set into the ground, leveled, plumbed, and backfilled a couple of feet with a sand/pea gravel mixture. Water level was within 6" of the backfill, sitting about 1 - 2 feet in the deep end of the pool. The pool then sat for about 3 weeks before backfilling was continued. It was backfilled about 2/3 up, with water matching up to about a foot below the top edge of the pool. A very heavy rain came the following day with 4 - 5" falling in a short time. The shallow end floated up and settled with backfill washing underneath. The pb came out and releveled the pool (ended up being a couple of inches higher than initially set), then completed backfilling.
We're now to the point of where coping and tile will be added. My concern is that there appears to be some waviness on the sidewalls of the pool. I didn't see this prior to installation and verified in photos that it didn't seem to be there. The pb said that he will work this out of the sidewalls before it's finished, but it is still there. Im assuming this was from hydrostatic pressure when the pool floated. During the rainfall, I could see the walls slightly pushing in just before it floated. If this waviness doesn't work all of the way out, will there be any potential structural issues down the road?
