Underground Mapping

Gizil's skilled site survey team can discover hidden objects in your facilities using remote sensing technologies such as electromagnetic and ground-penetrating radar (GPR). GPR maps subsurface information using high-frequency pulsed electromagnetic waves. It employs transmitting and receiving antennas that are dragged across the ground. The transmitting antenna sends short bursts of high-frequency radio waves into the earth. The wave expands out and descends. When it comes into contact with a buried item or a barrier with variable electrical characteristics, the receiving antenna records fluctuations in the reflected return signal.

Ground-penetrating radar (GPR) is a well-known field screening device for identifying and photographing underlying conditions. GPR is most typically used to detect subterranean things, including tanks, pipelines, drums, and shallow unexploded munitions. It may also be used to determine the depth of a shallow water table, identify soil layers and the bedrock beneath, and delineate trench borders.
