Soil Electrical Resistivity/Conductivity or ground Earth Resistance is measured with a Metrohm E1612 Earth/Ground Tester using the Wenner 4 electrode equal spacing method.
A number measurements can be made, each along a transect at varying spacing to characterise the strata to over 100 m depth.
Typical sites we work on are the jointing bay locations for HVDC power cables or substation locations within industrial sites
A survey point will normally consist of around six spacing (depth) variations to 30 m depth with transects at right angles to each other.
