Sub-Slab Tunneling

When You Need Sub-Slab Tunneling

Nobody wants the hassle and expense of having to call a plumber. We can relate. As fellow homeowners, we know that plumbing events (stoppages, water pressure issues, equipment failures) are a pain! Plumbing issues under the foundation of a home or driveway make many of our customers break out in a cold sweat. We’ve heard the horror stories, too.

Experienced plumbing service provider

Daniel’s has successfully completed more than 100 slab tunneling projects across Texas. We’ve experienced all kinds of soils and managed to solve every problem we’ve encountered.

Common sub-slab tunneling procedures

The most common sub-slab tunneling procedures relate to drain pipe replacement. We see quite a bit of this in older neighborhoods. Cast iron piping, while effective for many decades, does fail. Corrosion within the pipes, rust, mineral deposits, and the weight resulting from being buried stress the pipe until it fails. Tree roots also seek out water sources below ground. The combination of these forces often requires a full removal of the pipe and replacement with PVC piping.

Additional slab solutions

We find that tunneling under a slab is a better solution for homeowners than cutting the slab and extracting the pipe. Cutting slabs risks compromising the integrity of the foundation — the forces at work on foundations are substantial and complex. Tunneling is far and away the better solution in most instances. We work with structural engineers to make sure your foundation is just as sound as the day we arrived, and we support the new PVC piping under the slab so it doesn’t crack and cause secondary issues. We are thorough and we know that is what our customers expect. We work hard to alleviate as much hassle and stress as possible.

Quality results

The best part about our tunneling jobs is that you can be assured of the quality of our work. We guarantee the results with a warranty — and that warranty is transferable. Many homeowners call us when they intend to put their house on the market because they know that plumbing failures can kill their margins on the purchase price, or worse — scare away potential buyers. A transferable warranty reverses those concerns and even adds confidence for potential buyers. Daniel’s Austin will be in this market for many years; we aren’t a fly-by-night operation. In short, we will always honor our work.

Our customers are happy and we don’t walk away from the project until it is fully solved. We do it right the first time.
