Landfill Characterization - Utilizing geophysics to identify buried waste/debris Proper delineation of the extents of buried debris/materials that are associated with landfill sites can be a serious problem for companies that are planning on re-developing the site, or for environmental concerns associated with the … [Read more...]
Geotechnical Geophysics
The Benefit of Combining Geophysical Surveys with Drilling Programs Geotechnical drilling programs are designed to characterize the subsurface at a project site in order to properly design foundations and avoid any subsurface hazards. However, drilling alone only provides isolated locations where subsurface … [Read more...]
Geologic Hazards
Subsurface geologic hazards can pose problems for pre-construction design, the integrity of existing structures, and the general stability of a project site.The utilization of geophysical methods to characterize a site can help to identify unknown hazards, as well as properly delineate existing hazardous features. … [Read more...]
Geophysical Mapping of a Sinkhole
In January 2015, Pyramid Geophysical Services conducted a geophysical investigation at an open sinkhole (ground collapse) in a dry retention pond for a client at their remediation site in Tennessee. The survey was conducted to determine the lateral and vertical extent of the sinkhole feature in the subsurface, and to … [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...]
