Ground Penetrating Radar
Injection or induction of different frequencies in the form of electrical current is not always an option for service locating either due to a lack of access to the service or the underground services material make up. Therefore Ground Penetrating Radar is not only the next line of defence for underground service avoidance but sometimes the only option available. An underground service locating business without the capacity to employ Ground Penetrating Radar is not a comprehensive underground service locating business.
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. GPR is a non-destructive method where by high-frequency radio waves are transmitted into the ground. When the wave hits a buried object the receiving antenna records variations in the return signal which creates variations in the locating technicians’ data feed.
GPR technology is constantly evolving but currently is limited by certain factors including highly conductive soils, dense clays and soils that are salt contaminated. Aside from these limitations it is still the largest advance in recent times for the location of underground buried services and the only real option for locating pipes, conduits and ducts that comprise of non-conductive material.
At Utility ID we utilize this technology to its capacity to help you reduce exploratory excavation wherever possible.
