Scan Before You Drill. Every Time.
A core drill through an unmarked post-tension tendon doesn't give you a warning. A saw cut across an energized conduit in a slab doesn't ask if you checked first. Concrete looks uniform from the surface, but what's inside it isn't. GPR concrete scanning locates rebar, post-tension cables, conduit, and embedded utilities before a drill bit or saw blade touches the slab.
What Concrete Scanning Covers
Concrete scanning is used before drilling, coring, trenching, saw cutting, anchoring, or demolition to identify embedded hazards inside slabs and walls before work begins. Post-tension concrete is common throughout Texas commercial construction, in parking structures, elevated slabs, office buildings, and mixed-use developments. The pre-drill scan is the point where major damage and safety incidents get prevented.
- Rebar and reinforcement patterns
- Post-tension cables and tendons
- Electrical conduit and duct banks
- Plumbing and drain lines
- Embedded utilities
- Voids and subsurface anomalies beneath slabs
Concrete scanning works alongside private utility locating and GPR scanning to confirm what's below the slab and inside it before anyone drills, cuts, or cores.

Where Concrete Scanning Gets Used
Scanning is commonly performed on elevated decks, parking garages, podium slabs, tilt-wall panels, industrial floors, mechanical rooms, and occupied commercial buildings where blind drilling creates risk.
Elevated Decks & Parking Structures
Dallas-Fort Worth projects frequently involve elevated parking structures and dense commercial construction where blind drilling creates substantial risk.
See GPR Scanning →Podium Slabs
Podium slabs sit over occupied space or parking below, so a missed post-tension cable or conduit run has consequences beyond the slab itself.
Tilt-Wall Panels
Tilt-wall panels get scanned before anchoring or penetrations to confirm reinforcement and embedded conduit placement.
Industrial Floors
Houston projects often involve industrial facilities, petrochemical environments, and high-moisture slab conditions that call for careful pre-drill scanning.
Mechanical Rooms
Mechanical rooms carry dense embedded conduit and plumbing runs, so scanning before anchoring or coring keeps crews clear of active lines.
Occupied Commercial Buildings
Austin and San Antonio continue to see multifamily, municipal, healthcare, and adaptive reuse projects that require pre-drill scanning and slab verification in occupied buildings.
The Concrete Scanning Process
Four steps from layout review to clearance for the coring crew.
Layout Review
We review the drilling, coring, or cutting plan and confirm site access before scanning begins.
Scope the Scan Area
We identify which slabs, decks, or tilt-wall panels fall inside the cut or drill path.
GPR Scanning
We scan the marked area with ground-penetrating radar to locate rebar, post-tension cable, conduit, and other embedded hazards.
Marking & Clearance
We mark findings directly on the surface and clear the area for the coring crew, with field markings, PDF exhibits, or GPS-referenced documentation provided depending on scope.
