I will be don't worry. Wondering how many more there is.No I guessed that but I'd be on the phone even so!
Varies some are. Weren't what I would call a good fit when they were installed. As though the forms were badly warped. Builders offered to swap them.I would guess there may be some movement between the panels. It only needs to flex minutely which could easily happen when filling the pit. Is the damage near the middle of the panel?
