Stability Starts Below the Surface with Professional Tunneling
In Katy, expansive clay soil is every homeowner’s hidden enemy. After heavy rains, the ground swells and pushes against your slab; when it dries, the soil shrinks, leaving gaps that cause foundations to crack and plumbing to break. The result?
Costly slab leaks, uneven floors, and stress on your entire home. At FNF Foundation Repairs, we solve these problems with under slab tunneling Spring—a smarter method that repairs beneath your slab while keeping your interior floors safe from messy demolition.
