Geophysical Services

Geophysical tools and methodologies yield subsurface data to help you evaluate potential development sites quickly and non-intrusively, ahead of traditional exploration. Drawing on more than 50 years of experience, we develop a customized, cost-effective geophysical approach to compile and synthesize data to meet your project objectives. Ready to explore together?

– Electromagnetic Induction
– Seismic Methods
– Electrical Resistivity Methods
– And others

Deep Foundation Testing
– Crosshole Sonic Logging
– Thermal Integrity Profiling
– Pile Integrity Testing
– High Strain Dynamic Testing (PDA)
– And others

Instrumentation

Finding Buried Risks: How Geophysics Prevents Costly Surprises on Construction Sites

Seeing Sustainability Below the Surface – How Geophysics Testing Supports Environmental Innovation

Delivering accurate and precise results for successful projects

Geophysical methods can be used independently or integrated with other investigative methods such as test borings and other sampling programs, to provide subsurface information that cannot be gathered by other invasive methods. The resulting data can be used to plan or guide subsequent work including the placement of boreholes, wells, and exploratory shafts, or to avoid potential subsurface hazards. Our geophysics team can help you with the following project types and applications:

  • Determine soil and rock properties.
  • Map geologic structure and geologic hazards (landslides and faults).
  • Delineate and characterize landfills and hazardous waste.
  • Locate buried tanks, utilities, debris, and historical/archaeological objects.
  • Determine subsurface seepage zones.
  • Characterize karst potential and investigate sinkholes.
  • Assess pavements for thickness and integrity (delaminations).
  • Locate embedded reinforcing steel (e.g., PT cables) and conduits.
  • Locate subsurface voids.

Want to dig deeper?

Terracon’s geophysical services can help give you an idea of expected subsurface conditions on your project long before it’s time to break ground. A “smart exploration plan” featuring geophysics followed by borings or test pits can help reduce risk and support financial planning for your projects.
