Geophysical Services
BFW offers a variety of near-surface Geophysical Exploration services. Our expertise includes applying geophysical methods for environmental, engineering, exploration, and archeological targets across the Midwest and Southeast.
Geophysics has been a proven cost-effective tool for helping to locate and characterize subsurface features, reducing a project’s overall time and costs. Often geophysical explorations can provide information between boreholes providing an extended understanding of the subsurface. Geophysical explorations are often performed to guide the digging or drilling into points of interest for further, intrusive exploration.
Our team has in-depth knowledge of various geophysical methodologies and can determine the appropriate surveying type based on your project’s particular needs, the suspected subsurface conditions, and site conditions.
Geophysics can be used for:
- Seismic site characterization
- Karst characterization
- Buried debris detection
- Subsurface utility engineering (SUE)
- Buried tank detection
- Top of bedrock surveys
- Void detection
- Ground resistivity (for electrical grounding design)
- Vibration monitoring
