Ground Penetrating Radar, or GPR, has a wide range of applications, ranging from utilities and bridge deck investigations for transportation projects, to identification/location of buried features for environmental and archaeological studies, to geophysical studies.
Effective use of this technology is determined by several factors, including soils/geologic materials, depth, and the nature of the structures/materials being located. KMA has GPS technology which allows a wide range of applications.
This available technology includes three mobile GPS units; all of our units are self-calibrating, and 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 5 to 10 feet, dual frequency to depths of 8 to 15 feet, and triple frequency to depths of 15 to 30 feet. This unit features a folding rough terrain cart.
500 Megahertz (MHz) System
This system is the most applicable to utility locating, with a range up to 15 feet. It also has the widest range of uses-including utilities, drums, tanks, voids, geophysical (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/large 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.
