Drilling Services and Subsurface Investigations

Overcoming biased foundation directives can not only be demanding but can also be rewarding for a geotechnical engineer, and GeoStructures is truly at the forefront of this endeavor. GeoStructures has utilized innovative foundation systems on numerous projects—all of which dealt with difficult subsurface conditions, opposition, and local misconceptions. It is our conviction that, due to unique sets of conditions and influencing geologic factors, any sized project can benefit from a thorough subsurface investigation. GeoStructures is experienced in the following aspects of site characterization:

  • Test borings and test pits
  • Standard Penetration Testing (SPT)
  • Cone Penetrometer Testing (CPT)
  • Seismic Cone Penetration Testing (SCPT)
  • Undisturbed (Shelby) tube sampling of soils
  • Rock coring
  • Air rotary (percussion) drilling
  • Direct push or “geoprobe” sampling
  • Electromagnetic (EM), seismic, Ground Penetrating Radar (GPR) & microgravity surveys
  • Fracture tracing and photogrammetry (stereo pairs of aerial photos)
  • Geologic mapping
  • Geotechnical instrumentation
  • Hydrogeologic studies including piezometers and monitoring wells
  • Laboratory testing services
  • Rock structure measurements (strike and dip of beds, joints, faults, etc.)
