Tunnel Now is the excavating contractor Austin homeowners and businesses rely on for precision tunneling, slab leak repair, and underground plumbing work — without tearing up your floors or your yard. Whether you’re in Mueller (78723), Lakeway (78734), Round Rock (78681), or anywhere across the Austin metro, we’re the local crew that handles everything from the first dig to the final backfill.
When your slab shifts overnight or a sewer line backs up at your South Congress restaurant on a Friday evening, you need a crew that is familiar with the ground beneath you. Austin’s expansive black clay soils, hard limestone bedrock transitions, and rapidly aging pipe infrastructure, particularly in older neighborhoods such as Travis Heights, Bouldin Creek, and Allandale, cause underground problems that worsen quickly if not repaired.
Tunnel Now is an Austin-based excavation and tunneling crew that works on a daily basis in residential and commercial neighborhoods ranging from East Austin and Barton Hills to Pflugerville (78660), Cedar Park (78613), and the I-35 corridor through Kyle, Buda, and San Marcos. We understand how Central Texas soils move and what distinguishes a routine trench job from a full-scale utility emergency.
Sewer Repair Tunneling Expert hand-digging beneath your foundation to access and repair broken lines without causing damage to your tile, hardwood, or concrete floors.
Hydrostatic Testing Precision pressure testing to pinpoint hidden leaks and confirm the integrity of your underground plumbing across Travis, Williamson, Hays, and Bastrop counties.
Utility Emergencies Rapid response for collapsed mains, slab leaks, and parking lot sinkholes from Georgetown and Round Rock to Dripping Springs and Wimberley.
Our Services
Under-Slab Tunneling & Slab Leak Repair Slab-on-grade homes are the norm in Austin and its suburbs, as are the water and sewer lines running beneath them. When Austin’s notorious clay soils shift and crack the lines, the last thing you want is a jackhammer ripping through your kitchen tile. We hand-dig and machine-excavate tunnels beneath residential and commercial slabs, ensuring precision controlled digging, proper shoring, and a clean site at the end. If you have a failed hydrostatic test or suspect soil erosion beneath your foundation in Westlake Hills, Sun City Georgetown (78628), or Plum Creek Kyle (78640), under slab tunneling is almost always faster, cleaner, and less destructive than open-cut methods through your floors.
Under-Slab Sewer Repair Broken cast iron, collapsed Orangeburg, and bellied PVC underground sewer problems in Austin’s older neighborhoods do not resolve themselves. Homes in Crestview, Hyde Park, and Cherrywood (78722) still use original 1950s-1980s drain systems. We tunnel beneath your slab, remove the failed section, and install code-compliant PVC without disturbing any floor tiles.
Hydrostatic Testing Precision pressure testing to locate hidden leaks and ensure the integrity of your underground plumbing system is a necessary first step before beginning any major repairs.
Underground Plumbing Repair From failed water lines beneath your slab to corroded drain pipes deep in the ground, we handle underground plumbing repair for homeowners and businesses throughout the Austin metro area. We diagnose the problem first, then implement the best solution without causing unnecessary damage to your property.
Trenching & Pipe Replacement When patching is insufficient, our trenching services include the complete excavation and rerouting required for a long-term solution. We install new water and sewer lines for residential and commercial properties throughout the region, including Bastrop (78602) and Wimberley (78676), as well as Leander (78641) and Hutto (78634). This includes proper slope, bedding, and compacted backfill that will not settle or sink your yard six months later.
Foundation Access & Sub-Slab Excavation Austin’s clay-rich soils expand with every spring rain and contract hard during the summer drought, creating a cycle that stresses foundations in Driftwood, Dripping Springs (78620), and Manor (78653) year after year. When movement damages foundation piers or creates voids beneath your slab, repair crews must dig precise access points before beginning work. We provide foundation access excavation that protects the structure from above, with no guesswork on depth or angle.
Commercial & Municipal Excavation Restaurants, shopping malls, multi-unit properties, and industrial sites on the I-35 and I-183 corridors experience higher volume and faster failure. We offer rapid sewer excavation and commercial digging services for broken sewer mains, grease trap access, storm drain failures, and utility repairs beneath pavement. We also handle complete municipal sewer connections, new tie-ins, failed lateral replacements, and city main work in collaboration with the City of Austin, Travis County, and the utility districts serving Round Rock (78664), Georgetown, San Marcos (78666), and Bastrop. Permits were pulled. Inspections passed. Work done correctly.
