Ground penetrating radar (GPR) is an effective tool to rapidly image shallow bedrock under the right conditions. This project was conducted along a proposed pipeline alignment where geotechnical boring logs showed variable bedrock depth along the entirety of the alignment. The alignment consisted of a variety of ground … [Read more...]
GPR Investigation of Sub-Slab Voids
Pyramid Geophysical Services conducted a geophysical investigation at a facility in Asheboro, NC where the client had indicated that a water line had leaked/ruptured beneath a concrete slab-on-grade structure. The rupture resulted in visible water penetrating upward through seams in the concrete slab. Exploratory cores … [Read more...]
Concrete Inspection Using High Frequency Ground Penetrating Radar
Pyramid Geophysical Services 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 … [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 Geophysical Services 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 … [Read more...]
