Metodo Georadar (GR)
In accordance with UNI 11931 “Certification of technical personnel involved in non-destructive testing in the field of civil engineering and cultural and architectural heritage”
The georadar system can penetrate layers of material from a few centimetres to several tens of metres, although the detection capacity varies accordingly between small and large targets.
The fields of application have become vast, obviously including geology in the first place, archaeology, forensic activities, civil and hydraulic engineering, environmental engineering, war ordnance clearance activities, etc.
At the end of the course, Level 2 Certified Technicians will be able to independently carry out surveys, interpret radargrams and prepare survey reports to be delivered to clients.
