The place where I work is having problems with their pool. They have a cement bottom pool and what we think is fiberglass siding. The sides are bubbling and starting to leak. In certain areas on the siding if they are pushed on they move, like there is a bubble or nothing behind the side wall. The pool was built in 2001. Do you have any suggestions on how to fix it, if there is a way to repair it for now? If we have to replace it? What do we replace it with?
