Commercial Tunneling And Under-Slab Access In Texas
There are two ways to reach foundation work beneath a slab: through the floor, or under it. Which one makes sense depends on what sits on top. When the space above is a clinic, a leased suite, or a sales floor, opening the floor means interrupting the business, and tunneling beneath the slab may keep it open.
G.L. Hunt Commercial provides tunneling and under-slab access for qualifying foundation projects across Texas. The method may allow specified work to be completed beneath the structure without opening the finished space directly above it.
Access For Foundation Work Beneath Occupied Slabs
Under-slab tunneling is an access method rather than a stand-alone structural repair. It may be incorporated into a broader foundation plan when crews need to reach an area beneath a commercial slab, including locations identified for pier installation.
The right approach depends on the building, the affected section and the repair scope. Before recommending a path forward, G.L. Hunt evaluates the property and considers how under-slab access may fit into the larger foundation plan.

Where This Matters Most: Occupied Buildings
Tunneling may be relevant when the required foundation work is located beneath an area where direct interior access would create additional complications. Commercial foundation work often involves more than the structural condition itself. The plan must also account for how the property is used.
A healthcare facility may require coordination around patient care. A multifamily property may need to preserve access for residents. A retailer may need customer-facing areas to remain usable. These considerations can affect work zones, project phasing and scheduling.
G.L. Hunt plans commercial work around occupied buildings, operating-hour constraints and phased access when the scope allows. After-hours or weekend scheduling may also be considered when appropriate for the property.
How G.L. Hunt Develops The Scope
The recommendation follows the assessment: the commercial team documents the concern, brings in in-house engineering when sealed plans or structural review are required, and plans the access work alongside the foundation repair it supports. Crews on G.L. Hunt payroll perform the core work, so assessment, planning, and fieldwork stay connected.
What Affects The Cost Of Under-Slab Access?
There is no single price for commercial tunneling because the scope depends on the property and the repair plan. The location, the amount of access, and the building’s operating constraints define the work.
Commercial Coverage Across Texas
G.L. Hunt Commercial is headquartered in Fort Worth and serves commercial properties throughout Texas through offices across the state. Large out-of-state projects may be considered case by case.

Common Questions About Under-Slab Access
Is Tunneling The Foundation Repair Itself?
Not necessarily. Tunneling provides access beneath the slab. The repair performed through that access depends on the structural condition and the approved scope.
Can Tunneling Be Used Beneath An Occupied Building?
It may be considered when foundation work is required below an occupied portion of a commercial property. The final recommendation depends on the building layout, repair location and operational requirements.
Does Every Foundation Project Require Tunneling?
No. The appropriate access method depends on where the repair is located and how the building is configured. G.L. Hunt evaluates the property before recommending tunneling or another approach.
What Will The Proposal Explain?
The proposal explains the defined scope, the foundation work being supported and relevant access or scheduling considerations. Project-specific documentation is addressed as part of the final scope.
