the slab couldn’t be jackhammered to repair the leaking sewer pipe, because of the risk of cutting one of the cables in the post tension slab.  (Visit our Slab Leak page for more information about repairing pipe leaks under post tension slabs).  The plumbers had no choice but to dig under the home to repair the broken sewer pipe.

They were able to use sewer camera equipment to find the location of the broken pipe.  Then came the hard part…tunneling several feet beneath the house to find and repair the break.

And, when the line had been exposed, and the broken sewer pipe repaired, there was still more fun to come.

The plumbers replaced the dirt surrounding the sewer pipe itself, but the length of the tunnel meant there was just no way to get acceptable compaction of the soil.

With more homes being constructed with post tension slabs, Phoenix plumbers need the experience and the expertise necessary to replace both broken water pipes (slab leaks) and broken sewer pipes located under these slabs.
