Void Investigation
Microgravity Survey of a
High School
Utilizing seismic reflection/refraction, electrical imaging, or microgravity mapping, THG can image sub-surface voids, caves, mines, and many other underground anomalies. Precise 3-D mapping provides information for design and engineering prior to construction.
Surface seismic mapping has been used to determine the potential risk to over 1,000 wind turbine sites across the United States and Canada.
