Speedwell Earthing Compound is used as an earth electrode backfill and ideal for use in difficult soil condition to lower reduce soil resistivity. It is a grayish black, fine granular material used in place of other concrete collective like Silicon Dioxide and Carbon. It is also permanent, stable and maintenance free solution to obtain low resistivity in the form of conductive concrete. It prevents earth electrode material against corrosion. Mix the compound with water in the ratio of 1:2 to form a gel.
