I have these tubs that have a tiny little raised edge that goes all around (not bumps or legs, like a ridge that goes around the whole bottom side), that is probably half a mm thick. Since there will be water bowls etc. in the middle weighing down I bet the middle will have some parts touching the tape too. Is this OK?
The tubs can sit directly on the flexwatt with no issues.
