Tunneling offers a smarter path forward: 

  • Protective: No need to replace flooring after repairs—your interior stays safe. 
  • Time-Saving: Faster repairs compared to breaking and restoring slabs inside the house. 
  • Cost-Conscious: Avoids hidden costs of interior demolition and remodeling.

Under slab tunneling is a method used to access plumbing or foundation areas beneath your slab without tearing up your interior flooring. In Fresno, homeowners often face slab leaks caused by irrigation-heavy soils, shifting clay, or aging pipes. Tunneling is required when those leaks are buried deep under hard-to-reach slab sections. Without tunneling, the alternative is costly demolition inside your home.

Time matters when you’re dealing with leaks or cracks. For most Fresno homes, tunneling and repairs are completed within 2–5 days, depending on tunnel length, soil conditions, and repair complexity. Compare that to interior demolition, which can stretch into weeks of dust, noise, and expensive flooring replacement—tunneling keeps your life running smoothly.

It’s natural to worry about your yard. That’s why we carefully choose entry points that minimize damage to lawns, flowerbeds, or outdoor features. Once repairs are complete, we backfill the tunnel and compact the soil, leaving your yard as close as possible to its original state. Most homeowners are surprised at how little evidence remains after our process.

Every project is unique factors like tunnel length, soil type, and repair needs affect cost. However, tunneling is usually far more affordable than breaking through interior floors and paying to replace tile, carpet, or hardwood. In fact, according to the Foundation Repair Association, interior excavation can cost 30–40% more than tunneling. That’s why we always provide a clear, upfront estimate so you know what to expect.
