Vertical Electrical Sounding (VES)

VES is a technique that makes it possible to obtain information about the subsoil electrical resistivity in depth. Variations in the electrical resistivity can be associated to different properties of the subsoil, such as water content, mineralogy, porosity, among others.

The work in the field consists in using two electrodes for current injection (A and B) and other two for potential measuring (M and N). The distance between the electrodes is gradually increased to obtain data at depth.

 

The vertical electrical sounding it's commonly used for :

Application in support for the design of grounding systems where the goal is to identify the depth of the most conductive soil layer, as well as the degree of the subsoil’s corrosiveness. This method allows experts to evaluate big areas in a short period of time, reducing costs in the construction projects.
