What is Ground Penetrating Radar (GPR)?

Ground penetrating radar (GPR) has been widely used in the geological and archeological industries since 1970. Today’s GPR applications frequently call for locating objects through concrete and asphalt as well as beneath soil.

The portability and ease of operation of modern GPR systems allows the technician to easily move around a jobsite and to record a large amount of data in a short period of time. Through the use of radar waves transmitted by high frequency antennas we are able to interpret the data gathered by our equipment to locate many embedded objects, as well as measure slab thickness. Scanning depth for concrete is typically 18” or more, depending on the age and quality of the concrete. Objects in concrete include rebar, conduits, pipes, etc.

Ground Penetrating Radar (GPR) can also be used for soil applications. The scanning depth can vary greatly depending on the type of antenna used. The common uses for such scans are to locate such items as utility lines and buried tanks and drums. This accurate, non–invasive technology is producing enormous savings in construction, engineering, and maintenance.
