Ground Penetrating Radar

Ground Penetrating Radar (GPR) is GeoSonics/Vibra-Tech’s most widely used and broadest range solution for seeing virtually anything below the surface.

Ground penetrating radar (GPR) is an established technology used for investigating shallow geologic and hydrologic features. GPR is extremely useful in locating man-made features such as buried drums, tanks, pipes and other metallic objects. Another popular use is locating rebar in concrete or detecting voids beneath concrete or asphalt. GPR operates on the simple principle that electromagnetic waves emitted from a transmitter antenna are reflected from buried objects having different electrical properties than the host material. The signals detected at a receiver antenna and recorded provide a detailed cross section of the subsurface that is similar in appearance to a seismic reflection record. The depth of penetration of the radar pulse is controlled by site conditions and the frequency of the antenna chosen.
