At DFW Foundation Repair, we are experts in under-slab tunneling for plumbing and foundation repair.
With decades of experience and thousands of feet successfully tunneled, we deliver safe, effective, and non-invasive solutions for under-slab leaks, broken pipes, and plumbing installations — without compromising your foundation.

Why Choose Tunneling Over Breaking Through the Slab?

When you have a leak or broken sewer line under your home, you typically have two repair options:

  • Option 1: Jackhammer through your concrete slab, risking major structural disruption — and often missing the leak altogether if it’s not directly beneath the break point.

  • Option 2: Tunneling from outside the home, carefully following the plumbing lines until the leak is located and repaired.

Tunneling is the preferred method because it:

✅ Protects your foundation
✅ Prevents unnecessary damage to your flooring and interiors
✅ Accurately tracks down leaks without guesswork
✅ Provides safer, more effective access to problem areas

While labor-intensive, tunneling delivers better outcomes and avoids further compromising your slab.

How Tunneling Under Concrete Slabs Works

Our process is straightforward but requires great skill and caution:

  1. Digging the Access Shaft
    We start by excavating a 4-foot by 4-foot opening beside the concrete perimeter beam of your home or commercial building.

  2. Creating the Tunnel
    We carefully dig under the slab beam, expanding the tunnel as needed to allow for safe material removal and worker access.

  3. Maintaining Safety Standards
    We take safety very seriously:

    • Ventilation systems (fans or portable air conditioners) supply fresh oxygen inside long tunnels.

    • Our crews are trained to work safely even when tunneling extends 50-100 feet or more under large properties.

    • Extreme caution prevents tunnel collapse or worker fatigue.

  4. Locating and Repairing Pipes
    Once the damaged pipe is located, we carefully expose it and replace it with high-quality PVC piping.

  5. Protecting the New Pipes
    We suspend new pipes with metal hangers anchored into the slab.
    This ensures that future foundation movement won’t crush the pipes — a crucial step that many companies skip.

  6. Backfilling the Tunnel
    After repairs are completed:

    • We refill the tunnel carefully, watering and compacting soil for stability.

    • Excess soil is responsibly spread, graded for proper drainage, or hauled away to a certified disposal site.

From start to finish, we handle everything — so you don’t have to worry.
