Pyramid has years of experience utilizing Ground Penetrating Radar (GPR) equipment and processing software to analyze geologic site conditions, evaluate the nature and integrity of subsurface strata, and locate buried objects such as UST’s, drums, or waste/debris. We own both a GSSI UtilityScan DF multi-frequency radar unit as well as a GSSI SIR 2000 GPR System with a variety of antennae frequencies dependent on the nature of the buried material, site conditions, and depth of interest. Our radar surveys are fast, accurate, and can be tied into GPS coordinate systems that allow for improved locating and visualization of survey results.
Past projects where GPR has proved to be beneficial include locating UST’s (often in conjunction with Electromagnetic Surveys), delineating the extents of buried waste in existing or abandoned landfill sites, mapping depth to bedrock, locating buried utilities, locating septic leach fields, and general geologic site characterization. Pyramid also incorporates high frequency GPR antennae for concrete inspection surveys to locate rebar, post-tension cables, and observe moisture content of slabs.
