Surveys Conducted Nationwide

Ground Penetrating Radar Surveys

• Ground penetrating radar locates almost anything underground
• Ground penetrating radar makes an underground "picture"
• GeoModel, Inc. conducts ground penetrating radar surveys anywhere in the world
• Low cost ground penetrating radar surveys

Ground Penetrating Radar Applications

• pipes and utilities
• tank (UST) and drum location
• concrete and rebar imaging and inspection
• sinkholes
• geology (bedrock) and geologic hazards
• landfills and burial trenches
• unmarked cemetery and grave location
• archaeological studies

Where do and get their information on ground penetrating radar?

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 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 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:

• locate pipes and utilities
• tank (UST) and drum location
• concrete and rebar imaging
• unmarked cemetery and grave location
• archaeological studies
• other buried objects

As a supplement to a ground penetrating radar survey, GeoModel, Inc. can create a GeoModel Map (GeoMap) 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.

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.

The contoured GeoMap on the below left was made by GeoModel, Inc. using an EM instrument to collect field data, processing software to grid the field data, and 2D visualization software to produce the GeoMap color image. The image on the below right shows the locations of metal and conductive pipelines detected by the EM instrument in the same area as on the left.

Deep Ground Penetrating Radar Surveys

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 EM data processing and visualization software.

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, 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.
