Ground Penetrating Radar

Ground Penetrating RadarGround 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.

Ground Penetrating RadarMultiple-Frequency GPR

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.

KMA Ground Penetrating Radar Technology100 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.
