Ground Penetrating Radar (GPR)

By directing an electromagnetic wave into a concrete structure and measuring the response, features such as steel reinforcement, voids, the concrete backwall, and other features of interest can be detected. This work is often completed in scans along a given element on a test grid to generate a 3D view of the features, their depth, and their condition. BDI has developed its own ASNT TC-1A certification program for its GPR professionals and deploys a variety of different technology platforms depending on the speed, precision, or depth of testing needed.
