Groundbed Design

For underground structures requiring cathodic protection, the location and nature of the site where the anode is placed needs careful consideration. A low soil resistivity, which would otherwise be classified as a highly corrosive soil, is not the only factor which determines the location of the anode. Other factors to be considered include the presence of foreign metallic structures, accessibility and availability of a power source. The location which is specifically prepared to house a single or a combination of anodes is called a groundbed.
