Under slab tunnel work in San Antonio
When a pipe breaks under your foundation, tunneling lets us reach it from outside so the floors inside can stay in place.

Under slab tunnel work done right
Many San Antonio homes sit on a slab foundation, with drain and water lines running underneath. When one of those lines breaks, someone has to get to it.
Tunneling goes in from outside and under the foundation. We dig the tunnel, repair or replace the pipe, and backfill when the work is done.
What we handle
- Under slab drain and sewer line repairs
- Under slab water line repairs
- Tunneling to avoid breaking up interior floors
- Backfilling after the repair
When tunneling is the right call
- A leak or break confirmed under the slab
- Sewer line damage under the house
- Finished floors you do not want torn up

Right off the bat Jonathan and Jesse pointed out issues that I didn’t know were bad or getting to that point. They also mentioned faulty things with previous work that was done. They were very professional and thinking long term so I would never have to deal with this again. They were the lowest estimate of all the 6 others I received. Jonathan was very communicative with me and answering all the questions I had pertaining to the estimate and work, including the poorly installed water heater I had the previous year.
