Ground Penetrating Radar - GPR

Ground Penetrating Radar offers an excellent imaging solution (for both metallic and non-metallic targets) to reliably in a  non-destructively manner gather important underground information accurately, efficiently and in real time. When using GPR, both position and depth can be marked out on site and later composed into 3D reports if desired.

GPR acts as both a transmitter and receiver.  It transmits high-frequency radio waves into the ground that detect any change in soil conditions by reflecting off any disturbance, such as wet soil, rocks, metal, plastic, etc.   These disturbances show up as anomalies that are hyperbola in shape on the GPR screen.  It is up to the GPR technician to interpret what the anomalies represent.   The technician will then mark the ground showing the location of the buried utilities.  

What are the pitfalls of GPR?

GPR is not without its limitations. GPR radiowave signals are absorbed by the ground with some soils (clays, saline) greatly limiting exploration depth. GPR effectiveness is thus site specific and can vary significantly from location to location.
