What is GPR?

GPR stands for Ground-Penetrating Radar. It is a geophysical method that uses radar pulses to image the subsurface. This non-destructive technique uses electromagnetic radiation in the microwave band (typically from 10 MHz to 2.6 GHz) to detect reflected signals from subsurface structures. Common applications include locating buried utilities, geological investigations, detecting voids, and assessing the condition of roadways and bridges.
