We Have the Experience

For more than 20 years, Missouri S&T faculty, post-doctoral staff, and students have acquired engineering geophysical data with the objectives of mapping subsurface geological features of interest and/or imaging man-made structures.  The images we generate often enable engineering firms to make more informed and reliable decisions regarding construction, maintenance and/or mitigation.  Our crews have extensive field experience in Missouri and adjacent states, and have also participated on several international archeological investigations, geotechnical engineering studies, and water resource projects.

Our Capabilities

Missouri S&T is home to a wide range of state-of-the-art imaging equipment and supporting processing and interpretational software. Our labs maintain the following imaging technologies: electrical resistivity tomography (land and marine), spontaneous potential, induced polarization, ground conductivity, ground penetrating radar (air-launched and ground-coupled), metal detectors (time-domain and frequency domain), shallow reflection seismic, refraction seismic (conventional and tomographic), multi-channel analyses of surface waves, refraction micro-tremor, sub-bottom profiling, side-scan sonar, echo-sounding, ultrasonic surface wave, and impact echo.

Bridge Deck assessment based on ground penetrating radar data and limited core control.
Probable seepage pathway through earthfill dam based assessment of spontaneous potential and electrical resistivity tomography control.
Sinkhole imaged on 2-D electrical resistivity tomography profile.
Asphalt (bituminous mix) pavement imaged on 2-D ground penetrating radar profile.
Abandoned underground storage tank imaged on a 2-D ground penetrating radar profile.
Cross-section showing variable depth to top-of-rock based on multi-channel analyses of surface wave data (confirmed by follow-up borings).
Six graves are imaged on the 2-D ground penetrating radar profile.
