Magnesium Soil Anodes, Cathodic Protection - Houston

High Potential Magnesium Anodes (Hi-Po Mags) High Potential Magnesium provides excellent cathodic protection in low resistivity soil conditions. They are recommended for applications where soil resistivity is more than 2,000 ohm-cm, and less than 10,000 ohm-cm. If soil resistivity is above 10,000 ohm-cm, BK recommends an impressed current system.
