Ground Penetrating Radar Scanning

The Advanced Construction Services team inspecting a concrete floor.Before working on a concrete floor (i.e. warehouse floor, basement floor, etc.) it’s important to locate areas on the floor where it is clear to drill. Ground penetrating radar (GPR) scanning is a simple, fast and nondestructive way to see obstacles embedded in the concrete.

We use GPR scanning to locate in-floor heating, wiring, pipes, rebar, etc. embedded in the concrete. The floor is scanned using a 4’x4’ grid. Information is uploaded into a computer, and careful measurements are taken to mark spots where holes can be drilled.

During our repairs, work continues without disruption in the areas surrounding our repair.
