Tunneling Under the Slab in Dallas, TX — Safe, Clean & Non-Invasive Slab Leak Repair (Starting at $4,200)
When a slab leak is located beneath your home’s foundation, tunneling is often the safest, cleanest, and most effective repair method. Instead of breaking into your flooring, we excavate a tunnel from the outside of your home, allowing full access to the leaking pipe without damaging your interior floors, tile, or walls.
At Texas Slab Leaks LLC, we specialize in professional tunneling under the slab for homeowners throughout Dallas–Fort Worth. With over 30 years of experience, Master Plumber Michael Blue (RMP 36580) oversees every tunneling project to ensure structural safety, accurate repairs, and proper backfilling.

What Is Tunneling Under the Slab?
Tunneling is the process of digging a safe and secure access tunnel beneath your home’s foundation to repair or replace damaged pipes — without tearing up your flooring.
✔ No jackhammering
✔ No dust inside the home
✔ No breaking tile or wood floors
✔ No interior cleanup needed
✔ Ideal for preserving remodeled or high-end flooring
This method is preferred by homeowners who want a long-term fix without disrupting the inside of their home.
When Is Tunneling the Best Slab Leak Repair Option?
Tunneling is most recommended when:
- The leak is located beneath the home, away from interior walls
- You have expensive flooring (tile, hardwood, engineered wood)
- You want to avoid jackhammering through floors
- Large or complex repairs are needed
- Plumbing lines are difficult to access from inside
- You want long-term access for future inspections
If the leak is under a bathroom, kitchen, laundry room, or hallway, tunneling often provides the safest and cleanest repair.

How Our Tunneling
Process Works
Every slab leak is different. We offer all three professional repair methods, and we guide you toward the safest and most cost-effective solution.
1. Leak Detection ($325 Flat)
Before tunneling begins, we accurately locate the leak using:
- Acoustic detection
- Thermal imaging
- Pressure testing
- Tracer gas
Accurate diagnostics = smaller tunnel + lower cost.
2. Tunnel Excavation
Our excavation crew safely digs a tunnel under the foundation to reach the leak location.
We ensure:
✔ No structural impact
✔ Proper depth and slope
✔ Safe soil removal
✔ Tunnel stability at all times
We do not cut corners — safety is top priority.
3. Pipe Repair or Replacement
Once we reach the leaking water or sewer line, we:
✔ Repair or replace damaged sections
✔ Check surrounding piping for wear
✔ Test all repaired lines for leaks
✔ Ensure proper functionality before backfilling
We fix the leak thoroughly — not temporarily
4. Backfill & Compaction
Once repairs are complete, we carefully backfill the tunnel with compacted soil to maintain structure and prevent settling.
✔ Proper compaction
✔ Clean restoration
✔ No damage to your property
We leave your yard clean and safe.
For homeowners who want to understand the safety standards behind excavation work, you can review the International Residential Code foundation and excavation guidelines on the ICC website.
