Interior foundation tunneling for slab homes requiring piling support beneath areas unreachable from the perimeter. Serving Tarrant, Wise, and Parker Counties.
Foundation tunneling is used when interior slab areas require piling support unreachable from the exterior perimeter. Instead of breaking up interior floors, tunneling excavates a passage beneath the slab from outside — giving crews access to the underside of interior foundation areas without disturbing the living space above.
Tunneling is required when a structural engineer’s survey identifies interior settlement too far from the perimeter for exterior piling installation to address.
Step 1 — Engineer Specifies Interior Needs: Elevation survey maps high and low points. Interior settlement triggers tunneling as the access method.
Step 2 — Exterior Excavation: A tunnel entry is excavated from outside the foundation below the slab edge.
Step 3 — Piling Installation: From the tunnel, crews install pilings at precise engineer-specified locations.
Step 4 — Backfill & Restoration: The tunnel is backfilled and exterior restored. No interior flooring is damaged.
