The use of conductive backfills is one of the major techniques that can be used to lower soil resistivity and still achieve safety restriction imposed by standard regulations. The challenge is how to estimate the impact of a conductive backfill on local soil resistivity. In this study, electrodes were installed in a conductive backfill and their resistance measured. To determine impact of the conductive soil on the local soil resistivity, equivalent resistivity of the electrode (made up the resistivity of the conductive backfill and the local soil) was calculated using deep-driven analytical formula for soil resistivity calculation. Impact was obtained by a ratio of the equivalent resistivity to the resistivity of the local soil. To confirm the impact, electrodes were connected in a grid form and their combined resistance measured. The measured resistance value was compared with a calculated resistance value. The strong relation between the measured and the calculated values confirmed the impact. © Research India Publications.
