Geophysical Survey Systems, Inc. (GSSI) is the world leader in the development of ground penetrating radar. With cutting-edge products designed to address the most challenging applications, the GSSI name has become synonymous with accuracy, quality and reliability.
GSSI’s leadership in subsurface imaging equipment began with the introduction of the first commercial ground penetrating radar system in 1974. For over 50 years, GSSI has consistently led the industry with a series of “firsts” including the first digital GPR system, the first commercially available software package designed to process radar data and the first high-frequency GPR system specifically designed to scan concrete.
Today, GSSI offers the market’s broadest range of ground penetrating radar and electromagnetic induction equipment - covering a host of applications from archaeology and forensics, geology and environmental, utility detection and concrete inspection, to transportation infrastructure condition assessment.
Thank you for your interest in GSSI.
RST Instruments Ltd., founded in 1977, provides engineered solutions—sensors, instruments, communication systems and data management—for structural and geotechnical monitoring. RST supplies reliable monitoring instruments and data acquisition for dams, mines, tunnels, bridges, pipelines and buildings to support safe, productive structures.
GeoRadar® manufactures Stepped-FM Ground-Penetrating Radar systems used to find and image buried objects-usually things buried in the ground, but also objects in walls or rebar in concrete. Unlike many methods, GPR can find non-metallic objects: plastic pipe, dead bodies, even voids. The only requirement is that the material have different electrical properties than the host material. Of course, GPR can find metal objects as well. Ground Penetrating Radar can be used to locate: Buried utilities, rebar Plastic, cement, asbestos, clay or metal pipes Underground storage tanks and service lines Hazardous waste and buried drums, even plastic ones Archeological sites: foundations, burial sites, privys, chambers Forensic targets: bodies, weapons, drugs Topsoil characteristics and shallow geologic structure Dinosaur fossils, animal burrows UXO: unexploded ordnance, plastic land mines
