TeaCo Geophysical, LLC was formed in July of 2007 with the vision of providing architects, engineers, geologists, archeologists, and other associated professionals a non-invasive, non-destructive and safe option for the inspection of shallow subsurface conditions through the use of Ground Penetrating Radar (GPR). GPR surveys can often be completed more quickly and accurately than other types of investigations. This green technology utilizes electromagnetic energy to compare and contrast the electrical properties of materials being characterized. As GPR data is collected, a digital record is produced and saved on a computer, creating a geographical representation in real time. This allows technicians to mark subsurface objects during acquisition.

        Professionals and superintendents save incalculable hours and money by identifying these subsurface targets while avoiding undue damage to surrounding areas. GPR provides an added safety net to job sites, by helping to avoid injuries, damage to utilities, and hazardous spills. By having the fore knowledge of where subsurface objects lie, earth can be moved safely and efficiently. In addition to the ability to mark targets in real time, the data captured in the field can be subsequently processed by TeaCo technicians to create a permanent map of the location of subsurface targets. If requested by the client, TeaCo can simultaneously implement a DGPS into the data string in order to create the ability to have a permanently georeferenced map of the area investigated. The ability to produce 3-D maps is also available. The information provided by these processes can be invaluable when attempting to mitigate or analyze areas of concern for any given project.

        "One of the best features of GPR is that it provides a real time, interpretable cross sectional view of the subsurface. Despite many mapping and 3-D visualization developments and advances, some professionals think that it is the only way to display GPR data. Going the next step of generating plan map images from data collected in grids greatly enhances the ability to understand and interpret GPR survey data. Displaying GPR data as a series of plan maps slicing deeper into the subsurface allows users to see spatial correlation of targets. Important targets can be differentiated from targets of non interest. For example, responses from utilities will produce linear targets while rocks will produce point targets."

         GPR services offered by TeaCo have potential applications in multiple industries with little to no adverse effects to the environment or to the health of workers that may be present during the execution of the survey. For instance, on many occasions it is common for concrete to be x-rayed and it is required that those areas be evacuated due to the potentially harmful gamma radiation emitted during imaging.

        GPR can be used in a variety of media to include rock, soil, ice, fresh water, concrete, pavements, bridge decking, and structures. It is capable of detecting changes in materials, cracks, voids, and buried objects. TeaCo Geophysical, a SDVOSB (Service Disabled Veteran Owned Small Business) company based in Mississippi, is positioned and capable to satisfy this niche in the engineering, geotechnical, scientific, and environmental disciplines in the southeast.
