services_geophysicsGeophysical surveying is a useful and cost-effective solution for investigating and characterizing subsurface conditions non-destructively. We have extensive knowledge and experience in the application of a comprehensive range of geophysical methods for environmental, geotechnical, hydrogeological and engineering projects. The methods and technology we use, like Ground Penetrating Radar (GPR), help locate, detect, delineate and characterize many natural or manmade subsurface features. A professionally designed, well-executed geophysical survey can reduce project time and costs. Our geophysical services group has successfully partnered with government and private industries and completed an award-winning study for the U.S. Army Corps of Engineers.

We specialize in the following geophysical applications and methods:


    • Buried tanks and drums
    • Karst features – including caves, caverns and sinkholes
    • Voids beneath roadways and structures

>Buried utilities

  • Former underground mines and landfills
  • Depth to bedrock
  • Buried munitions and other military-related materials
  • Rebar and post-tension cables in concrete


  • Seismic reflection, seismic refraction and seismic tomography
  • Ground penetrating radar (GPR)
  • Resistivity
  • Electromagnetics (EM) and magnetics
  • Spontaneous potential (SP)
  • Borehole geophysical logging
  • Vibration monitoring
