Under slab tunneling is the process of digging a tunnel beneath your foundation to access plumbing lines or make structural repairs. In Friendswood, this is especially important because our clay-rich soil expands and contracts with changes in weather. That movement often causes slab leaks or foundation stress. Instead of tearing up your flooring—which can be messy, costly, and disruptive—tunneling provides a safer, cleaner way to reach the problem areas.

Most residential tunneling projects in Friendswood are completed within 2–5 days. The timeline depends on the length of the tunnel, soil type, and the complexity of repairs. While breaking through your floors can leave you with weeks of construction mess, tunneling allows you to stay in your home comfortably during the process. Our team keeps the project moving efficiently so you can return to normal life quickly. 

We understand that your yard is just as important as your foundation. Our team carefully selects entry points to minimize impact on lawns, gardens, and landscaping features. Once the work is complete, we backfill and compact the soil so your yard is restored as closely as possible to its original condition. Most homeowners are surprised at how little evidence remains after the job is done. 

The cost depends on tunnel length, soil conditions, and the type of repair needed. On average, tunneling is often more affordable than breaking through your flooring and then paying for new tile, carpet, or wood replacement. With FNF Foundation Repairs, you’ll receive an upfront, transparent estimate with no hidden fees. We design services that fit both your budget and long-term stability needs. 

Yes. That’s one of the biggest advantages of under slab tunneling. It provides direct access to repair plumbing leaks, replace broken sewer lines, and address foundation issues all at once. This saves you time, reduces costs, and avoids the hassle of multiple repair projects. 

Absolutely. When performed by trained professionals, tunneling is one of the safest ways to access foundation and plumbing issues. Our process prevents structural weakening and ensures that your foundation remains stable. Every step we take is designed to protect your home, from careful excavation to proper soil compaction after backfilling. 

If your plumbing leaks or foundation problems are located under the slab, tunneling is almost always the best option. Signs that you might need tunneling include: 

  • Persistent plumbing leaks beneath your home
  • High water bills without visible leaks 
  • Foundation cracks or sinking areas 
  • Damp spots on flooring that can’t be explained

In fact, according to the American Society of Civil Engineers, nearly 25% of U.S. homes experience structural distress due to expansive soils like those in Houston. 

A free inspection can confirm whether tunneling is the best solution for your home.
