Water Damage Restoration
Slab Leak Water Damage
Under a slab there is no drip to hear and no stain to watch, and the wet carpet turns up two rooms from the break.

Where a house sits directly on concrete, a leak underneath it has no way to declare itself. Arlington, Lakeland, Atoka, Cordova and Medina are overwhelmingly slab-on-grade, and so is nearly everything built on the suburban edge in the last several decades. The water follows the underside of the pour or soaks into the fill, and because the mapped soil here is well drained and moderately permeable, a small leak can run for months without ever showing up as a wet spot in the yard.
What shows instead is indirect. The bill steps up and stays there, a patch of tile stays warm over a hot line, running water is faintly audible with the house closed, a floating floor lifts along one edge. Finding it is most of the job — pressure isolation of the hot and cold sides, acoustic locating and thermal imaging narrow it to a few feet of pipe before anyone touches concrete. Then there is a real choice between opening the slab at that point and abandoning the run to reroute it overhead.
What people notice first
- A warm strip on a tile or vinyl floor with the heat off
- Water audible in the walls with every fixture closed
- A water bill that doubled with no change in use
- Grout lines darkening in one part of a room
- Baseboard swelling along the bottom edge of an interior wall
How the work runs
Confirm the leak is under the slab
The meter test comes first: everything closed, the dial watched, then the house isolated at the main to separate a leak inside the building from one on the service line. Water heaters, irrigation and outside bibs get ruled out, since each of them mimics a slab leak on a bill. Confirming before excavating avoids opening a floor for a leaking toilet flange.
Locate it to within a few feet
The hot and cold sides are isolated and pressurized separately, and acoustic equipment plus thermal imaging narrows the position along the run. Locating well is what keeps the concrete cut small. A guess costs more in floor covering than the locating work costs to do properly.
Decide between access and reroute
Opening the slab reaches the failure directly and is often right for a single break in an accessible spot, while a reroute abandons the buried run and moves it overhead or through a wall, which suits older copper that has already failed more than once. Cost, floor covering and the age of the plumbing decide it. That decision gets made with the homeowner before anything is cut.
Dry what the leak soaked
Water under a slab wicks up into wallboard, cabinet bases and the underside of flooring, and none of it dries once the finish floor is back down over it. Mats and cavity ventilation pull moisture out of the concrete and out of the wall bottoms, tracked at marked points. Concrete gives up moisture slowly, so this stage runs longer than a comparable surface loss.
Rebuild and check the rest of the run
The patched concrete, the flooring, the baseboard and the paint go back after the readings settle. Where the failure was pinhole corrosion in old copper, the remainder of the buried run is worth an honest conversation, because the next leak is normally in the same pipe. Cabinets and toe kicks that were opened get closed last.
A drying log is left on site, not carried away, so anybody who walks in can read what the readings have been doing without ringing to ask.
What this looks like in West Tennessee
Slab-on-grade is the newer half of the housing stock and it sits exactly where the growth has been. Nearly all suburban-edge construction since the mid-1980s rests on a poured slab over silt fill, and the Ford and SK battery campus near Stanton, about $5.6 billion and roughly 5,700 jobs, is adding much more of it in a county that had very little. Concrete puts supply lines under the finish floor instead of over a crawl space where a flashlight would find them. The mapped soil drains well and takes moderate infiltration, so a leak below the pour can run for months without wetting the yard.
The money conversation therefore happens before the locating gear leaves the truck, because opening concrete and rerouting overhead are priced differently and the floor covering weighs as heavily as the plumbing. Permits follow the county rather than the job. Shelby, Tipton, Fayette, Madison, Haywood, Dyer, Crockett and Gibson are marked exempt by the State Fire Marshal, which makes a residential permit a municipal matter where a codes office exists, while Chester, Hardeman and Lauderdale take the state permit in unincorporated areas. Electrical work needs a state permit in every one of them. At $25,000 and above the state contractor's license applies, and verify.tn.gov settles it in a minute.

Questions that come up
How do I tell a slab leak from something else?
Shut every fixture in the house, then watch the water meter for fifteen minutes. Movement with everything closed means water is going somewhere, and the next step is closing the main valve at the house to separate the service line from the interior plumbing. A warm floor with the heat off strongly suggests the hot side, since a cold-line leak gives you the bill without the warm patch.
Do you always have to break the concrete?
No. Rerouting the line overhead leaves the failed pipe in the ground and is frequently the better answer for an older copper system, particularly where the break sits under cabinets or a tile floor that cannot be matched. Breaking in makes sense for a single break with clear access and newer plumbing everywhere else. Both are legitimate; the choice is about the rest of the system.
How long does the drying take afterward?
Longer than a surface loss, because concrete releases moisture slowly and the wet zone is usually wider than it appeared. A week is common where wallboard bottoms and cabinet bases took water, and the numbers govern rather than the schedule. Flooring goes back only after the slab reads at a level the flooring manufacturer will stand behind.
Can a slab leak damage the foundation?
The soil here is silt rather than the expansive clay that heaves and shrinks in other parts of the country, so seasonal movement from moisture alone is less of a story than it would be further south. Water running under a slab for a long time can still carry fines out of the fill and leave a void. If there are new cracks, sticking doors or a floor that has moved, that assessment belongs with a structural engineer.
Before you call
If flame or smoke is still visible, that is a 911 call and not this one. Ring us once the fire service has released the building and told you it is safe to enter.
