Why Choose Tunneling for Plumbing Repairs?

When plumbing issues occur beneath a concrete foundation, there are typically two main approaches: breaking through the slab from inside or tunneling underneath the foundation from outside. Tunneling is often the better choice because it:

Protect

Protects Your Interior

No need to tear up flooring, tile, or carpet.

Home’s Value

Preserves Your Home’s Value

Avoids structural risks and cosmetic damage inside.

Better Access

Provides Better Access

Allows our plumbers to fully access and replace problem sections of pipe.

Long-Term

Ensures Long-Term Reliability

Repairs are done outside the foundation for thorough inspection.

Our tunneling process is designed to balance efficiency and safety, ensuring your plumbing system is fixed without unnecessary destruction to your home.

The Methodical Plumbing Tunneling Process

We take pride in making the tunneling process straightforward, professional, and transparent for our customers. Here’s how it works:

Thorough Camera Inspection

We start with advanced sewer camera inspections to pinpoint the exact location of the break or leak beneath the slab. This allows us to determine where tunneling should begin, ensuring accuracy and reducing excavation costs.

Professional Tunneling

Our licensed plumbers carefully dig a tunnel from the outside of your home’s foundation to the damaged plumbing line. We use specialized tools and safety practices to maintain the integrity of your foundation and landscaping.

Precision Plumbing Repairs

Once the pipe is exposed, we complete the repair or replacement using high-quality materials and proven plumbing techniques. Whether it’s a sewer line replacement, water line repair, or a pipe connection fix, we ensure the job is done right.

Tunnel Backfilling and Clean-Up

After the repair is complete, we backfill the tunnel with care and restore the area as close to its original condition as possible. Our team values cleanliness, so we leave your property neat and ready for normal use.

Common Problems That Require Tunneling Services

Many plumbing issues beneath foundations require tunneling for proper access. The most common situations we handle include:

  • Slab Leaks: Caused by corroded pipes or shifting foundations.
  • Broken Sewer Lines: Cracked, collapsed, or offset sewer pipes under the home.
  • Water Line Leaks: Hidden leaks causing higher water bills or water damage.
  • Drain Line Failures: Severe clogs, blockages, or collapsed sections of pipe.
  • Foundation Shifts: Plumbing lines affected by soil movement or settling.

If you’ve noticed unexplained water on your floors, higher utility bills, foul sewer odors, or slow drains, you may need a professional tunneling inspection and repair.
