I'm going to jackhammer my basement's concrete floor to install plumbing for a new bathroom.
Normally, after the plumbing is done, we should pour concrete to it again.
What will happen if I just "cover" it with something (plywood? with tiles on top) so I don't have to jackhammer the floor again in the future, should I need access to the plumbing?
Will I get weird condensation / water problems?
