Voids, fractures, weak materials, abandoned mines, and other unforeseen subsurface conditions can lead to significant impacts in infrastructure projects. Our division, Quantum Geophysics, uses geophysics to pinpoint small, unpredictable features more effectively than traditional exploratory drilling, especially on large sites and long linear structures. Through our vast experience and extensive equipment inventory, we provide you high-quality surveys that yield better solutions, on-time and within budget.

Our Expertise

What We Do
We use a full range of surface and down-hole geophysical methods to identify subsurface conditions in support of engineering, environmental, and groundwater investigations. Read more about Quantum’s capabilities.

What You Can Expect
  • Extensive Project Experience
    We’ve conducted more than 500 geophysical surveys since 1990. Project sites include roads, bridges, dams, levees, power plants, fuel storage facilities, wind and solar farms, military facilities, harbors, landfills, salt mines, brownfields, Superfund sites, airports, commercial and industrial facilities, schools, subdivisions, and quarries.
  • Better Detection of Potential Impacts
    Geophysical methods produce a continuous profile of the subsurface making it easier to detect features that otherwise might not be disclosed by widely spaced exploratory borings. 
  • Specialized Geologic Hazards Evaluation
    We have expertise in evaluating sinkhole activity and identifying abandoned coal mines using microgravity, 2-D and 3-D electrical resistivity imaging (ERI), and/or multi-channel analysis of surface waves (MASW). Read more about Geologic Hazards.
