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.
