Homes & remodels
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.

Built for Oklahoma homeowners and the trades who work in their houses — especially older slabs with no drawings and newer post-tension foundations.

Panel upgrades, mini-splits, and underground feeds should not find a tendon or a water line.
Scan existing concrete before you tie in an addition or cut a driveway for utilities.
If a floor feels hollow or a foundation is being altered, GPR can show thickness and empty space without demolition.
A missed post-tension cable in a house foundation is a structural emergency. A missed water line is a flood. Residential scanning is cheaper than either.
Call Tommy's GPR. We scan across Oklahoma and can usually tell you how soon a tech can be on site.
