Common Reasons for Under Slab Tunneling in Houston

Houston's environment creates specific conditions that make under-slab plumbing problems common:

Slab Leaks

Pipes beneath your concrete foundation can develop leaks from corrosion, shifting soil, or wear over time. These leaks waste water, damage your foundation, and create expensive problems if left unaddressed. Tunneling provides access to repair these leaks without destroying your floors.

Corroded or Damaged Pipes

Older Houston homes often have galvanized steel or cast iron pipes that corrode over decades of use. Houston's acidic soil and mineral-rich water accelerate this corrosion. When these pipes fail beneath the slab, tunneling allows for targeted replacement of the damaged sections.

Tree Root Intrusion

Tree roots seek moisture and can penetrate sewer lines beneath your foundation. In Houston's moist clay soil, mature trees develop aggressive root systems that find even small cracks in pipes. Tunneling provides access to remove roots and repair the damaged pipe.

Shifting Foundation

Houston's expansive clay soil expands and contracts with moisture changes, causing foundation movement. This shifting can crack, bend, or break rigid pipes beneath the slab. Tunneling allows us to assess and repair pipes damaged by foundation movement.

Pipe Replacement for Remodeling

When remodeling kitchens or bathrooms, homeowners sometimes need to relocate plumbing lines. Rather than tearing up expensive new floors, tunneling provides access to move or replace pipes beneath the slab before finishing work is installed.

When Under Slab Tunneling Is Recommended

Reason 01

High-Value Flooring

Homes with granite, marble, hardwood, or custom tile where replacement costs are substantial.

Reason 03

Multiple Repairs Needed

When several under-slab pipes need attention, one tunnel can provide access to multiple problem areas more efficiently than multiple slab breaks.

Reason 05

Foundation Concerns

Properties with structurally suspended flat slabs where cutting through the slab should be avoided due to engineering concerns.

Reason 02

Recent Renovations

Properties that recently completed expensive remodeling work should avoid tearing up new finishes.

Reason 04

Occupied Homes

When residents cannot relocate during repairs, tunneling allows work to proceed without displacing the family.

Our Under Slab Tunneling Process

2. Tunnel Path Planning

Our technicians plan the shortest, most efficient tunnel route from an exterior access point to the problem area beneath your slab. We consider obstacles like landscaping, utilities, and foundation beams. The path is marked and measured before digging begins.

3. Hand Excavation

We hand-dig the tunnel using specialized tools designed for working in confined spaces. The tunnel is typically 3 feet wide by 3 feet tall—large enough for a technician to enter safely. We shore up the tunnel walls as needed to ensure stability and safety throughout the repair process.

4. Plumbing Repair or Replacement

Once the tunnel reaches the damaged pipe, our licensed plumbers perform the necessary repairs. This might include replacing a leaking section, clearing a clog, or installing new piping. All work is done to code with proper materials and connections.

5. Backfilling and Restoration

After repairs are verified and tested, we carefully backfill the tunnel with compacted soil. We restore the exterior area as close to original condition as possible, including re-grading and replacing any disturbed landscaping materials.

6. Final Inspection

We conduct a final inspection to ensure repairs are complete and the exterior area is properly restored. You'll receive documentation of the work performed for your records.

What Is Under Slab Tunneling

Under slab tunneling is a non-invasive method of accessing plumbing, sewer lines, and drain pipes located beneath your home's concrete foundation. Instead of jackhammering through your floors and disrupting your living space, we hand-dig precise tunnels from the outside of your home to reach the problem area underneath the slab. This specialized excavation technique preserves your flooring, minimizes mess, and allows your family to remain in the home during repairs.

Houston homes built on concrete slab foundations have water lines, drain pipes, and sewer lines running directly beneath the slab. When these pipes develop leaks, clogs, or damage, traditional repair methods require breaking through the concrete from inside your home. This means removing flooring, furniture, and creating significant disruption to your daily life. Tunneling offers a better alternative by creating external access to the same pipes.

Our tunneling process involves carefully excavating a narrow tunnel—typically 3 feet by 3 feet—from an access point outside your home to the location of the damaged pipe. The tunnel provides enough space for technicians to crawl under your foundation and perform necessary repairs or replacements. Once the work is complete, we backfill the tunnel and restore the exterior area, leaving your home's interior untouched.
