Ground Penetrating Radar (GPR) (Ground Radar) Survey Services
All GPR surveys are conducted or supervised by:
Ground Penetrating Radar Applications
cemetery and grave location
tank (UST) and drum location
concrete and rebar inspection
geology and geologic hazards
landfills and burial trenches

Ground Penetrating Radar
GeoModel, Inc. is registered with the FCC and uses only FCC-approved GPR equipment
Ground penetrating radar (GPR) produces an underground, cross-sectional, two-dimensional image scan 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 (GPR) surveys using antennas with various frequencies. Depths of GPR underground scans can be as deep as 50 feet in sandy or silty soils, using a low frequency ground penetrating radar antenna.
A higher frequency antenna can examine the near surface, to a depth of 15 feet, in greater detail. The ground penetrating radar signal does not go as deep in clayey soils.
Shallow Ground Penetrating Radar Surveys
Shallow ground penetrating radar surveys are conducted by one person, hand-towing or ATV-towing the antenna.
Applications for a shallow ground penetrating radar survey include locating pipelines and utilities, locating underground storage tanks (USTs) and drums, inspecting concrete, detecting rebar, locating unmarked gravesites, and conducting archaeological studies.

Deep Ground Penetrating Radar Surveys
Deep ground penetrating radar underground scanning surveys are conducted with a low frequency GPR antenna, such as a 200-MHz antenna that can reach depths of up to 35 feet in sandy soils.
Applications for deep ground penetrating radar include landfill and burial trench delineation, geology and bedrock depth studies, and karst and sinkhole location.
GeoModel Map Surveys
GeoModel, Inc. can create a color-contoured GeoModel Map underground scan of your property, using 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), burial trenches or landfills containing metal, or inorganic contamination.

For a GeoModel Map, mapping is done automatically using a vehicle or ATV driven system. Results can be obtained in a short time period, making our system cost-effective for large industrial sites, as well as for smaller sites. Metal utility lines, and most other conductive utility lines, are mapped using our unique technique.

Concrete Inspection Surveys
GeoModel, Inc. can conduct ground penetrating radar (GPR) underground scanning of concrete to locate rebar, pipes, post 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.
GeoModel, Inc. uses GSSI (Geophysical Survey Systems, Inc.) GPR equipment to conduct its GPR survey services.
