Slab-on-grade construction became standard in North Charleston through the redevelopment years, which makes slab leaks a routine local problem rather than a rare one.
How you notice
- A water bill that jumps with no change in usage
- A warm patch on the floor, which means a hot line
- Running water audible with everything shut off
- Damp or lifting flooring in one area
- The meter creeping with every fixture closed
Located before anything is opened
Acoustic equipment, pressure isolation and thermal imaging narrow the leak to a small area first. That means one targeted opening in the slab instead of exploratory demolition across a room. Anyone proposing to start breaking concrete before locating the leak has the order wrong.
Repair, reroute or repipe
A single leak on sound pipe is a spot repair. A line that has failed once and will likely fail again is often better rerouted overhead, leaving the slab alone entirely. Repeated failures on the same system mean the material is the problem, and repiping is the honest answer.
Turn the water off meanwhile
A slab leak does not stop on its own and the damage compounds. Closing the main while you decide limits what this ends up costing.
