Ground Penetrating Radar

GeoModel, Inc. is registered with the FCC and uses only FCC-approved GSSI GPR equipment

Ground penetrating radar GPR produces an underground, cross-sectional, two-dimensional image scan of the soils and subsurface features.

GeoModel, Inc. conducts ground penetrating radar GPR surveys using antennas with various frequencies.

Depths of GPR underground scans can be as deep as 20 to 30 feet in sandy or silty soils, using a low frequency GPR antenna.

A higher frequency antenna can examine the near surface, to a depth of 12 feet, in greater detail.

If your site has clayey soils, then the ground penetrating radar signal does not go as deep, no matter which frequency antenna is used.

Shallow Ground Penetrating Radar Surveys

Shallow ground penetrating radar GPR surveys are conducted by one person, hand-towing or ATV-towing the antenna.

Applications for a shallow ground penetrating radar survey include:
red dotlocating pipelines and utilities,
red dotlocating underground storage tanks (USTs) and drums,
red dotlocating unmarked gravesites, and
red dotconducting archaeological studies.


Deep Ground Penetrating Radar Surveys

Deep ground penetrating radar GPR surveys are conducted with a low frequency GPR antenna, such as a 200-MHz antenna that can reach depths of up to 20 to 30 feet in sandy soils. In clay soils, the depth reached is less.

Applications for deep ground penetrating radar include:

Concrete Inspection Surveys

GeoModel, Inc. can conduct ground penetrating radar (GPR) underground scanning of concrete to locate rebar, pipes, 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.

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 Heat Map Surveys

GeoModel, Inc. can create a color-contoured GeoModel Heat Map of your property that represents the features present below ground.

The GeoModel Heat Map shows areas of low EM "heat" values (light blue to green colors) and areas of increased EM "heat" values (yellow to red colors)

Low heat values may represent natural, background, or dry soil conditions.

High heat values are indicative of landfills, low pH or salt contamination, or increased groundwater flow.

Very low EM values (deep blue) usually represent buried metal features or objects,such as metal utilities, tanks or drums.

home and property with groundwater seepage problems, buried tank, septic system, old buried foundation, and buried utility lines


The color-contoured image (Google GeoModel Heat Map) above was obtained using an EM survey with GPS positioning. The various colors represent different underground features.

For a GeoModel Heat Map, mapping is done automatically using a vehicle or ATV driven EM survey system.

EM data 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 EM survey technique.
