Rebar
Map bar location, spacing, and cover so cores miss the mat instead of cutting through it.
Ground penetrating radar · Oklahoma
See through the slab before you cut.
Tommy's GPR locates rebar, post-tension cables, conduits, pipes, and voids in concrete — up to 24 inches down — so Oklahoma crews can core, saw, and drill without a hit.

What the scan finds
Five things you do not want in a core.
Post-tension cables
Find live tendons before a saw or bit can release them — the highest-stakes hit on a slab.
Conduits & wiring
Trace electrical and data pathways so a renovation does not take a circuit, or a building, offline.
Pipes
Locate water, sewer, and process lines in the slab before they become a flood.
Voids
Identify hollow spots and deterioration that can drop a slab or swallow a drill.
Why GPR, not x-ray
One side of the slab. No radioactive film. Same-day marks.
Concrete x-ray needs access to both sides of the slab — a receiver on one face, film on the other — plus radiation controls. That slows occupied buildings and slab-on-grade work. Ground penetrating radar reads the slab from the top. We roll, we mark, you cut.
Read how GPR works →01
You mark the hole
Show us the core, cut, or trench. A photo and a city are enough to get started.
02
We scan the slab
GPR pulses the concrete from one side and reads rebar, tendons, conduits, pipes, and voids.
03
The floor gets painted
Scan & Mark leaves the hazards on the slab. 3D reports add layer-by-layer images.
04
You cut with a plan
Trades work the same day. No x-ray film, no access to the ceiling below.
Services
A mark on the floor, or a report in the file.
Scan & Mark
Show us the hole. We scan around it and mark the slab so you can cut the same day.

Residential, commercial, and industrial.
Homes & remodels
Residential
Homeowners, plumbers, and remodelers call Tommy's GPR when a bathroom, kitchen, or garage needs a hole in the concrete. We mark rebar, post-tension cables, conduits, and pipes so the first cut is the safe one.
Residential scanning →Offices, retail, healthcare, schools
Commercial
Commercial slabs hide the utilities that keep a building open. Tommy's GPR scans offices, stores, clinics, schools, and restaurants across Oklahoma so cores, anchors, and trenches do not take a space offline.
Commercial scanning →Plants, warehouses, energy
Industrial
Industrial concrete is crowded — rebar, conduits, process piping, and voids under years of overlays. Tommy's GPR scans plant floors and warehouses so equipment moves, trench drains, and anchors do not become a line-down event.
Industrial scanning →Service areas
Oklahoma, city by city.
