How Tunneling Works

Tunneling is the process of digging horizontal underground pathways (tunnels) beneath a home’s slab foundation to access plumbing lines, piers, or footings. It’s often preferred over cutting through the interior slab because it preserves your flooring, minimizes mess, and allows you to stay in your home during repairs.
Common reasons for tunneling in Carthage homes:
- Slab leak repair
- Water line or sewer line rerouting
- Under-slab plumbing system replacement
- Foundation pier access and installation
- Root barrier installation or soil stabilization
- Avoiding interior demolition and restoration costs
Tunneling is especially effective when multiple plumbing lines or piers need attention under different parts of the home.

Benefits of Tunneling Over Traditional Access

Tunneling is widely preferred by homeowners because it minimizes disruption and preserves interior finishes, making it ideal for occupied homes or recently renovated properties.

Why homeowners choose tunneling:

No need to break interior floors or damage flooring
🛏️ You can stay in your home during repairs
Ideal for accessing under-slab plumbing and piers
Minimizes dust, noise, and interior mess
Preserves property value and aesthetic integrity
Better for resale homes or homes with tile/wood floors
Often reduces total cost when flooring restoration is factored in

When repairs are done from underneath, your home remains livable and protected throughout the entire process.

What to Expect During the Tunneling Process

At Carthage Foundation Repair, we take a strategic approach to tunneling. Our crew uses manual tools and excavation techniques that prioritize safety, stability, and cleanliness.

Step-by-step tunneling process:

Initial Inspection
- We evaluate the issue (plumbing leak, pier adjustment, etc.).
- Tunnel path, access points, and soil conditions are documented.
Permits and Planning
- We obtain any necessary permits and coordinate utility checks.
Tunnel Excavation
- A 2- to 3-foot wide tunnel is manually excavated from the exterior, extending beneath the slab to the repair area.
- Tunnels are dug to depths of 3–5 feet, depending on slab height and pipe or pier placement.
Repair Execution
- Once the tunnel reaches the problem area, the plumbing or foundation crew performs the necessary work.
- Repairs are inspected for code compliance and long-term durability.
Backfilling and Soil Compaction
- Tunnels are backfilled using excavated soil or fresh material.
- Soil is compacted in layers to prevent future foundation settlement.
Final Grading and Cleanup
- Yard is graded to its original condition, and the area is cleaned.

Tunneling projects typically take 2–7 days depending on tunnel length, number of access points, and repair complexity.
