If you’ve ever faced an under-slab plumbing leak or foundation issue, you know how stressful it can be—damaged flooring, dust, and days of noise. But in 2025, tunneling has transformed how professionals approach repairs. It’s clean, efficient, and doesn’t require tearing up your home’s interior.
At FNF Foundation, we’ve seen firsthand why contractors are moving away from interior demolition and choosing as the preferred solution for both Foundation Repair and slab access.
What Is Tunneling in Foundation Repair?
Tunneling involves digging a horizontal path beneath the foundation from outside the home to reach plumbing or structural components without touching interior flooring. Instead of breaking through tile or hardwood, a tunnel is dug from the exterior—leaving your home untouched inside.
