UNDER-SLAB & TUNNELING

WHEN THE PROBLEM IS UNDER THE FOUNDATION.

Reaching the plumbing beneath your home — by tunnel or by slab access — and repairing it with our own crews.

THE PROBLEM BENEATH

WHAT UNDER-SLAB PLUMBING PROBLEMS ARE.

When plumbing runs beneath a concrete slab foundation, a leak or a failed line isn't something you can reach from above. The pipe is buried under the slab your home sits on. Reaching it means getting underneath — either by tunneling from outside or by opening the slab directly. Either way, it's serious work, and it's the kind of job we're built for.

TWO WAYS TO REACH IT

TUNNELING OR SLAB ACCESS.

There are two main ways to reach plumbing beneath a foundation, and the right one depends on the situation. We recommend the approach after diagnosis — never before.

TUNNELING BENEATH THE HOME

  • Accessed from outside the foundation
  • No cutting through the slab inside the home
  • Lets crews reach and repair pipe from below

DIRECT SLAB ACCESS

  • Reaching the pipe through the slab itself
  • Used when tunneling isn't the right fit
  • Decided after the problem is located

REACHING PIPE FROM BELOW.

Tunneling is accessed from outside the foundation, so crews can reach and repair the pipe from below without cutting through your slab or working inside the living space. It's real excavation work — and not every plumbing company has a dig crew for it. We run our own in-house dig crews, so there's no handoff.

SLAB ACCESS UP CLOSE

REACHING PIPE FROM ABOVE.

Slab access reaches the pipe through the slab itself. It's used when tunneling isn't the right fit — for example, when the problem is in a spot that's hard to reach from outside or when the repair needs direct access from above. It involves opening and later restoring the slab, which is part of why it's a decision made after diagnosis, not before.

NO HANDOFFS

OUR OWN DIG CREWS.

Most plumbers locate a problem and then hand the digging off to someone else. We don't. We have our own in-house dig crews for tunneling and slab access, so the team that diagnosed the problem is the same team that reaches it and completes the repair. One company, start to finish.

AFTER THE REPAIR

WHAT HAPPENS NEXT.

Once the pipe beneath the foundation is repaired or rerouted, we carry the job through to completion — including backfill, cleanup, and the follow-through that closing out a major repair requires. If you're dealing with a real estate transaction, testing before you close can save you from surprises. If a leak keeps returning, a repipe may be the more permanent answer.

QUESTIONS, ANSWERED

UNDER-SLAB FAQ.

How do you decide between tunneling and slab access?+
It depends on where the problem is, what's above it, and what the repair requires. We locate the failure first, then recommend the approach that fits the situation — never before diagnosis.
Will tunneling damage my foundation?+
Tunneling is designed to reach the pipe from below without cutting through the slab. Like any excavation, it should be done by an experienced crew — which is why we run our own dig crews in-house.
Do I need to leave my home during the work?+
It depends on the approach and the location of the problem. Tunneling is done from outside, so it often means less disruption inside. Slab access may require working in the living space. We walk you through what to expect.
Can you handle both the diagnosis and the repair?+
Yes. We locate the problem, reach it with our own dig crews, and complete the repair — one company, start to finish, no handoffs.
