Tunnel Under Slab

At Davilas Excavations LLC, we specialize in trenchless tunneling techniques that protect your slab while allowing full access to repair underground plumbing and drainage systems — all without damaging your floors.

What Is Tunnel Under Slab Repair?
Tunnel under slab repair is a method used to access plumbing or utility lines beneath a concrete foundation without breaking the slab itself. Instead, tunnels are carefully excavated around the property to reach the repair area from below.

This technique ensures minimal disruption inside the home or business, preserving flooring, tiles, and structural integrity while allowing direct access to the damaged area.
