In practice, the geophysical methods have substantial application in solving problems in geotechnical engineering. These methods cover a range of investigations that determine the underground soil structure and engineering properties of the material. The geophysical methods are used to determine the structure, thickness and properties of the individual layers below the ground surface, which foresees the construction of certain structures.
