What is a Ground Penetrating Radar (GPR)?
Ground Penetrating Radar (GPR) is a non-intrusive geophysical technique used to image the subsurface. It employs multi-frequency antennas (ranging from 200 to 600 MHz) and multi-polarization technology to provide detailed and accurate images of the ground below.
The use of multiple frequency antennas allows for the detection of both shallow, small-diameter services and those buried at greater depths. Additionally, GPR surveys can identify voids or other buried obstructions that may be present.
The process works by transmitting an electromagnetic pulse into the ground. The radar then records the strength and the time it takes for the signals to return after interacting with different materials beneath the surface. This data provides vital insights into the composition and structure of the subsurface, ensuring safe and informed decision-making for your projects.
