Soil resistivity is necessary to facilitate the design of an earth electrode system. Soil resistivity testing and subsequent modelling is fundamental to the design process.
Soil resistivity testing is performed using the Wenner method, in accordance within BS EN 50522.
Subsequent electrode design and modelling is performed using CDEGS software.
