Leaks Under the Concrete

Slab leak repair in Leesburg, VA begins with locating the leak precisely, because the pipe is buried under a concrete floor and every inch you break costs time and mess. Brick Street uses pressure testing, electronic amplification and infrared scanning to mark the spot, then either repairs that section through a small opening or reroutes the water line around the slab entirely. Watch for a rising water bill, warm or damp floors and a drop in water pressure. If you notice them, call (240) 969-4911, any hour.

A slab leak happens when a water or drain pipe running beneath a concrete foundation cracks or wears through. Soil under a slab shifts and settles over time, which stresses the pipes in it, and copper can corrode or wear thin where it rubs against concrete or gravel. Basement floors, slab-on-grade additions, garages converted to living space and many townhouses around Loudoun County have piping under concrete. Because leaks there are hidden, they often run for a long time before anyone notices. For leaks in walls and ceilings instead, see our pipe leak detection and repair service.

How a Slab Leak Shows Itself

You rarely see the water. You see what it does.

A warm spot on the floor

A hot water line leaking under the slab heats the concrete above it. Bare feet often notice it before anything else.

Damp flooring or seepage

Moisture wicks up through concrete into carpet pads, under vinyl and along baseboards, sometimes far from the leak itself.

Water bill climbing

Water escapes around the clock, so usage keeps rising even when the household's habits have not changed.

Lower pressure at the taps

A large enough leak steals pressure from the fixtures downstream of it.

New cracks in floors or walls

Water washing out soil under the slab can let it settle, which shows up as fresh cracks in flooring, tile or drywall.

LOCATING IT

Finding the Leak Without Breaking Up the Floor

Pressure testing comes first. We isolate the hot and cold lines and drain lines, then pressurize each to see which one is losing water. That tells us what we are hunting for. Next comes the pinpointing. Electronic amplification equipment lets a technician hear the sound of water escaping a pressurized pipe through concrete, and infrared sensors pick up the heat signature a hot-water leak spreads across a slab. Where the leak sits under a tub or another hard-to-reach fixture, these non-invasive methods matter even more. For drain lines under the slab, a camera inspection shows breaks and corrosion from inside the pipe. When we mark the floor, we are marking the leak itself, not a guess.

Repair Options Once It Is Found

The right fix depends on the pipe and how many problems it has.

Spot repair

A small opening in the slab directly over the leak, a new section of pipe, then the concrete patched. Best when the rest of the line is in good shape.

Pipe rerouting

Abandon the line under the slab and run a new one through walls, ceilings or the attic. Often the smarter choice when pipes are corroded or have leaked before.

Drain and sewer line work

Cracked drains under the floor are repaired or replaced and checked by camera before the slab is closed.

Patching and cleanup

After a spot repair, the opening is backfilled, compacted and closed with new concrete so flooring can go back down over a sound base.

Frequently asked questions

How do I know if I have a slab leak?

The most common signs are a warm or damp area of floor, a water bill that keeps rising without explanation, the sound of running water with every fixture off, and lower water pressure. Turn off all water and check your meter. If it still moves, the leak is somewhere in the system. A plumber can then pressure test the lines to see whether it is under the slab.

Is it better to repair a slab leak or reroute the pipe?

A spot repair makes sense when the leak is a single failure on otherwise sound pipe and the location is easy to reach. Rerouting is often better when the pipe is old or corroded, when there has already been one slab leak, or when the leak sits under cabinets, tile or a tub. We show you both options, with the reasons, once the leak is located.

Can a slab leak damage my foundation?

Yes, over time. Water escaping under a slab can wash away or soften the soil that supports it, which may let sections settle and crack. It also keeps flooring wet and can feed mold under carpet and behind baseboards. That is why it pays to locate and fix a slab leak promptly rather than living with a high water bill until the floor shows damage.

Does Brick Street jackhammer the whole floor to find a slab leak?

No. We locate the leak first with pressure testing, electronic listening equipment and infrared scanning, so any opening is small and placed directly over the problem. Many slab leaks are fixed without breaking concrete at all, by rerouting the line overhead or through walls. You see the plan before any concrete is cut.
