When your plumber tells you there's a leak under the slab, the next question is how to access it. Breaking up the concrete floor is one option — but it's expensive, messy, and leaves you with a major restoration project after the plumbing work is done. Tunneling from the exterior is cleaner, faster, and leaves your floors completely intact. Texpro Foundation Repair provides professional under-slab tunneling services throughout the Dallas area. Call 972-330-2652 for a same-day assessment.
When You Need Under-Slab Tunneling
You need under-slab tunneling when your plumber has confirmed a leak beneath your concrete slab and recommends accessing the pipe from below. Signs of a slab leak include unexplained increases in your water bill, warm spots on the floor, the sound of running water when no fixtures are in use, or sudden cracks in the slab. Tunneling is also used for foundation repair work that requires access to the soil beneath the slab, or for installing drainage systems under the foundation. If you have a confirmed slab leak, don't wait — the water is saturating the soil under your foundation every day.
Our Under-Slab Tunneling Process
We start at an exterior access point and hand-dig a tunnel beneath your slab, following the route to the plumbing or foundation component that needs attention. We shore the tunnel as we go to ensure safety and structural integrity. Once the plumber or foundation crew has completed their work, we backfill the tunnel with compacted material to restore proper soil support beneath the slab. The exterior excavation area is restored when we're done. Tunneling projects typically take one to three days depending on the distance and complexity.
