How to Fix the Leak
Ideally, you should call professional plumbers in case you sense great damage. With the help of modern equipment, plumbers can detect the slab leak and its location with minimal damage caused to the surrounding floor or walls. However, to repair the pipes, digging is mandatory. Plumbers can come up with solutions such as changing only the leaking portion of the pipe, or coating the pinholes in the pipe with a strong waterproof adhesive, etc. But in older housing structures, the plumbing system used is also very primitive.
