Pyramid completed a ground penetrating radar (GPR) concrete inspection survey in a municipal parking garage in North Carolina. The purpose of the survey was to locate rebar and post tension cables within the concrete floor slab of one of the parking decks. Geotechnical engineers were planning to core through the … [Read more...]
Ground Penetrating Radar
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 … [Read more...]
Ground Penetrating Radar to Map Septic Leach Field Drainlines
Pyramid has utilized ground penetrating radar (GPR) to locate and delineate the extents of septic leach fields and septic drain lines at a variety of locations. Typically, these drain field systems are constructed by digging trenches in the ground where perforated drain lines are placed and then covered/surrounded by … [Read more...]
Geophysical Clay Stratum Investigation
Pyramid was contracted to conduct a near‐surface geophysical investigation in Fayetteville, North Carolina, in an effort to identify the depth and extent of a subsurface clay stratum. The clay unit was of concern to an active chemical plant located at the site. Due to the potentially thin nature of the clay stratum … [Read more...]
