These metallic USTs are often left behind at old fuel service stations that have closed down. Old home heating oil tanks are also often left in the ground after … [Read more...]
Slope Stability Analysis Using Geophysics
Pyramid Geophysical Services was contracted to assist in a comprehensive evaluation of subsurface geologic and hydrogeologic conditions along a causeway in South Carolina. The causeway was experiencing slope failures and ground collapses. These failures were thought to be the result of both the presence of buried … [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...]
