Ground-penetrating radar 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. Break Away provides this service to locate Post-tensioned Cables and other Metal Structures “Embedded” within concrete slab or walls. Break Away does not locate underground utilities.
