Under-Slab Tunneling, a Non-Invasive Method for Underground Repairs

You probably agree that plumbing issues are not pretty. The most common one we see is a leak underneath the foundation, caused by damage in the drain line.

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 access to the point of failure from the outside.

You don’t have to fill your home with dust and debris and upend your whole life while plumbers take care of the repairs. An under-slab tunnel is a non-invasive method to get any plumbing work done with as little hassle as possible. 

Keep Your Home Clean and Leave the Mess Outside

By far the biggest advantage of under-slab tunneling is the ability to access any plumbing issues from the outside rather than inside.

If you have a backed-up toilet or a kitchen sink that leaks, there’s no need to rip a hole into your beautiful floor. It would leave you unable to use the bathroom or kitchen for weeks. To make matters worse, you’d also have to spend extra money redoing the flooring afterwards…

With under-slab tunneling, we help you address the issue while keeping the mess outside your home.

3. Enjoy Your Home

Many companies will dig your tunnel and leave it. At Anchor Foundation Repair, the last step of the repair job is to fill the tunnel back with dirt and cement. This secures the plumbing structure to prevent any long-term issues.

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.
