Ground Penetrating Radar (GPR)

Ground Penetrating Radar (GPR)

Learn More
GPR is used to scan through materials to identify defects within or behind.
We have access to multiple antennas and radar source sets, allowing us to scan through most earthy materials such as soil, brick, cement, and stone.
Example Client: MetroTech

How GPR Works

GPR detects subsurface anomalies and objects by measuring the time-of-flight and intensity of reflected radio waves. Our automated GPR system caters to maritime applications, offering automated GPR scans of large areas, reducing manpower and maximizing clarity on subsurface conditions for asphalt, soil, concrete, masonry. Despite its name, GPR is used frequently on surfaces other than the ground. Check out the robots that use the GPR system below:
