Is that pic above the worst of the wall damage? If it is, I had worse the night before we filled and a storm came up blowing the walls over backwards and some parts forwards, leaving creases and folds. We were able to take 2x4s with blankets and the wall in between and pound the creases out. You can't even see where any of that was now. How are your bottom rails? Good yet? Is it just wall damage? with bends and folds?

Maybe Dennis can give his opinion, I'm betting he has encountered some damaged pools with walls that buckled like that.
