Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to “image” the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from the subsurface structures.
GPR is becoming more familiar in the construction industry as a valuable and necessary tool. Prior to GPR, X-Ray was the only means of “looking” through concrete to identify structures. GPR is a safe, quick, and effective method that allows customers to scan concrete and locate buried structures such as rebar, post-tension cables, and conduits.
