This specially formulated anode backfill is used with either magnesium or zinc cathodic protection anodes to lower the anode to earth resistance and to help retain moisture around the anode, thus creating a more efficient ground bed.

The standard anode mixture consists of 75% gypsum, 20% bentonite and 5% sodium sulfate. A special mixture of 50% gypsum and 50% bentonite is available on request.

The backfill comes with prepackaged galvanic anodes, or is available in fifty pound paper bags.
