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.
