Deep utility surveys are in most cases a nightmare to any GPR operator. The fact is that most of the utilities are in urban areas where there is a high amount of EM noise sources. Usually it is a complex net of entangled utilities, buried trenches and shafts that needs to be recorded and interpreted. The deeper one has to go, the harder it is to collect good quality data for the final interpretation. Deep utilities are man made structures that can be found at the depths greater than 5 meters. A good set of examples are mining, metro and sewer tunnels.
