3D Resistivity Survey For Sinkhole/Underground Void Locating


Due to complexity and often 3D natures of subsurface conditions, 2-dimensional direct current electrical resistivity surveys (resistivity profiling) often can not provide the best results and the data interpretation is difficult. In the other hand, a 3D resistivity survey provides a much better prospective and the results more accurately reflect the subsurface conditions.

Enviroprobe recently conducted a 3D resistivity survey in northwest New Jersey to identify potential sinkholes for a residential property. There had been sinkhole openings in and around the properties. Through the survey, a number of potential sinkholes were identified.
