Ground Penetrating Radar works on a really simple method – it sends a tiny pulse of energy into the ground via an antenna. We then use an integrated computer to record the strength and the time it takes for the return of a reflected signal. Any variations in the subsurface creates a reflection back to the computer. Each type of material provides a different reflection – essentially a material like bedrock will provide a different reflection to an object like a pipe. We then go through the data and produce a report on the differences in the data collected that allows you to dig or build in the right area.
