Geotechnical projects usually rely on traditional sounding and drilling investigations to gain the information needed to satisfy the given task. Drillings are costly and only provide point information; the geology between these points needs to be assumed as the number of drillings is limited by the respective project budget. High resolution near surface geophysical methods can provide information to fill those gaps and can consequently limit the overall number of drill holes. Proper integration of these two datasets is important and we provide a number of case histories illustrating results of such combined projects. We mainly focus on Electrical Resistivity Tomography (ERT) as a sophisticated geophysical method to gain reliable data along point information from boreholes.
