Ground Penetrating Radar (GPR) has a wide range of applications, ranging from utilities and bridge deck investigations for transportation projects, to identification and location of buried features for environmental and archaeological studies, to geophysical studies.
Effective use of this technology is determined by several factors, including soils and geologic materials, depth, and the nature of the structures and materials being located. KMA has three mobile GPS units that allows for a wide range of applications. All of our units are self-calibrating, have auto configuration, and depth calibration.
The multiple frequency allows for a wide range of applications/depths, from very shallow bridge deck analysis to deep utilities locating. Single frequency is generally applicable to depths of five to ten feet, dual frequency to depths of eight to fifteen feet, and triple frequency to depths of fifteen to thirty feet.
500 Megahertz (MHz) System
This system is the most applicable to utility locating, with a range up to fifteen feet. It also has the widest range of uses, including utilities, drums, tanks, voids, geophysical barriers (strata/bedrock), law enforcement (forensics, etc.), and archaeological (burials and structures). This unit also features a folding rough terrain cart.
100 Megahertz (MHz) System
This system offers the greatest penetration and is most applicable to geotechnical and geophysical analysis. It is useful for location deep utilities, geophysical features, and deep buried foundations, tanks, and other structures. Though not as portable and light weight as the Multiple-Frequency and 500 MHz systems, this unit can be easily transported in a survey or utility van and carried by two persons.
