Abstract: Often, geotechnical explorations consist of a few, strategically placed boreholes and considerable interpolation and extrapolation by the geotechnical engineer. The information between boreholes in most exploration programs is simply expressed as a dotted line representing geologic horizons from one borehole to the next. In some situations, this may be all that's needed; but, what about in a complex geologic setting such as karst, where borings within three meters of each other can reveal completely different conditions? What would it be like to have actual information between boreholes? While the surface application of geophysical methods is widely applied and accepted in many industries, lesser-utilized borehole applications can provide valuable information between boreholes for the geotechnical community.
