Geophysical techniques are commonly used as part of geotechnical investigations for sinkhole claims of residential structures. GeoView, Inc. has performed thousands geophysical surveys for residential sinkhole investigations throughout Florida, Tennessee and Georgia. The investigations involve performing ground penetrating radar (GPR) and/or electrical resistivity imaging (ERI) to help identify karst features. In addition, a floor elevation study is conducted to detect changes in the slope of the floor of the residence.

GeoView, Inc. performed a geophysical investigation across a 200 acre site in Polk County, Florida. It had been reported that clay slimes from former mining operations had been deposited on the site. The purpose of the investigation was to help determine the horizontal and vertical extent of the clay slimes. Due to the large size of the site and limited budget, the investigation was conducted using Frequency Domain Electromagnetics (EM). The EM Survey was conducted by towing the EM-31 on a proprietary non-conductive sled on transects spaced 100-ft apart.
