Under-Slab Tunneling: a Less-Hassle Approach to Underground Repairs

Home plumbing issues are unpleasant, inconvenient, and nerve-wracking. A leak underneath your foundation caused by broken, rusted, or damaged drain lines is common and tricky to handle. Do you break through the slab for this? Are there other options?

While you would expect to turn your home upside down for such a repair, you don’t need to with under-slab tunneling. We excavate a tunnel underneath your foundation to give plumbers convenient access to the problem from the outside.

Tunneling is a non-invasive way to get any under-slab plumbing work done with less hassle. Plus, Anchor’s expert-level backfilling method uses mud-pumping to secure your home.

Keep on Living Inside Your Clean Home and Leave the Mess Outside

The biggest advantage of under-slab tunneling is the ability to repair under-slab plumbing issues from the outside rather than inside. You don’t have to fill your home with dust and debris, disrupting your life while plumbers take care of the problem.

There’s no need to rip a hole into your beautiful flooring or slab. Breaking through your foundation could leave you unable to use a bathroom or kitchen for weeks. Even worse, you then have to spend extra money replacing or repairing flooring afterward.

With under-slab tunneling, we help you address the issue while keeping the damage at bay and the chaos away.

Very professional locally owned company.

Had Craig out to do an inspection, very honest doesn’t try to sell you something you don’t need.

I felt he did a great job explaining current condition of foundation.



Craig is quick to respond, and has a very friendly, efficient, and professional crew.

Stood by the warranty with no questions when the heavy rains came through and we had to re-level.

10/10 would recommend.
