Ground Penetrating RadarAdd more spaceGeoModel, Inc. is registered with the FCC and uses FCC-approved GPR equipment
Ground penetrating radar (GPR) produces an underground cross-sectional, two-dimensional image of the soils and subsurface features. Three-dimensional GPR images, such as the one below, can be produced using raw field data and post-processing software.
GeoModel, Inc. conducts ground penetrating radar surveys using antennas with various frequencies. Depths of ground penetrating radar (GPR) can be as deep as 30 to 40 feet (10 to 15 meters) in sandy or silty soils, using a low frequency ground penetrating radar antenna. A higher frequency antenna can examine the near surface, from 0 to 10 feet (0 to 3 meters), in great detail.

Shallow Ground Penetrating Radar Surveys
Shallow ground penetrating radar surveys are conducted by one person, hand-towing or ATV-towing the antenna.
Applications:
Aerial photograph of survey area (on left, above), and GeoModel, Inc. As-built utility map based on ground penetrating radar (GPR) and metal detection (EM) data (on right, above).
As a supplement to a ground penetrating radar survey, GeoModel, Inc. can create a Site Scan Map of your property. GeoModel, Inc. uses EM and metal detection instruments and computer processing to create a full color contour map showing areas of buried metal utilities, pipes, drums, or tanks (USTs), or burial trenches containing metal.
The site scan map (below, left) shows the locations of buried metal pipes that were located by GeoModel, Inc. with our deep metal detector. The contour map below, right, was produced by Geonics' metal detector and Geosoft's Oasis Montaj.
Deep Ground Penetrating Radar Surveys
Deep ground penetrating radar surveys are conducted with a low frequency GPR antenna. Applications include: landfill and burial trench delineation, geology and bedrock depth studies, and karst and sinkhole location.
The image below (left) shows the results of a GeoModel, Inc. EM survey, for landfill and burial trench delineation, presented as a "Site Scan Map". The EM contour map below (right) shows the location of a sinkhole identified by the higher conductivity values due to increased groundwater in the sinkhole. The EM data was collected by GeoModel, Inc. along with GPS measurements and the EM data was contoured by GeoModel, Inc. using Oasis Montaj.
GeoModel, Inc. also uses EM and metal detection surveys to locate inorganic contaminant plumes. GeoModel, Inc. conducts EM and metal detection surveys using the GeoModel, Inc.-owned equipment shown below:

Concrete Inspection Surveys
GeoModel, Inc. can conduct ground penetrating radar (gpr)scanning of concrete to locate rebar, pipes, tension bars, and conduits in concrete structures. Our scanning can also detect voids within concrete slabs and under concrete slabs.
Our ground penetrating radar scanning can inspect concrete walls, concrete floors, slabs, airport runways, tunnels, abutments, dams, and garages. Asphalt roads and surfaces can also be scanned.
Cemetery and Grave Site Surveys
GeoModel, Inc. conducts ground penetrating radar surveys for locating unmarked grave sites and confirming marked grave sites at cemeteries nationwide.
