How it works
What to expect
Confirming the leak
We run meter and pressure tests to confirm a leak exists and isolate whether it is on the hot or cold side, ruling out toilets, irrigation, and other causes first.
Pinpointing the location
Using acoustic listening, electronic detection, and thermal imaging, we trace the leak to a precise location so the repair is targeted, not exploratory.
Repair plan and options
We explain what we found and lay out the viable repair approaches, such as spot repair, overhead reroute, or tunneling, with the trade-offs of each.
Repair execution
We complete the chosen repair, replacing or bypassing the failed section of pipe with durable materials and proper connections.
Verification testing
We pressure-test the repaired line, verify the meter holds steady, and confirm the area is dry before considering the job complete.
FAQ
Under-Slab Tunneling Access questions
How does tunneling work?
A tunnel is excavated from outside the foundation to the area beneath the leak, giving technicians working room to repair the pipe from below. The tunnel is backfilled after the repair is complete and tested.
Why choose tunneling over breaking the slab?
Tunneling avoids breaking interior floors, which is a major advantage under tile, hardwood, or stone. It is also useful for post-tension slabs where cutting concrete carries extra risk.
When is tunneling not practical?
Very rocky soil, high water tables, or leaks in locations unreachable from the perimeter can rule tunneling out. We assess feasibility during the detection and planning visit.
