So I know this has been discussed before but I wanted to mention my particular situation. We had our pool installed in March 2022. Our PB used gravel and spent time packing along the stairs and benches dumping more and more. We still have a hollow sound on the stairs and somewhat, but not as noticeable on the benches.
No one else seems to notice but I do. The walls and floors are solid as a rock and even the sides of the stairs seem hard. I don’t notice any flex when stepping on them either. Is there anything I should watch out for? I know fiberglass is insanely strong so I’m not worried about a foot going through it and I have no cracks or anything.

The pool is complete with concrete and the project finished so the PB has been paid. And I really don’t want to be ripping up concrete….

Thanks!
