Pyramid Geophysical Services offers a full line of geophysical capabilities to North Carolina and the entire east coast of the U.S. We have experience in a wide variety of geographical areas and projects, including hazardous waste sites, underground storage tanks, landfills, groundwater studies, and geotechnical investigations. We design geophysical surveys that meet the client’s needs in the most efficient and cost effective manner possible.
Our typical approach incorporates a multi-phase geophysical reconnaissance technique specifically designed to provide the most accurate site information possible while taking into account both the capabilities and limitations of the various geophysical methods we offer.
Pyramid prides itself on quality surveys. We make every effort to assure integrity of field data, including frequent quality assurance analyses during acquisition.
