Our specialized anode backfill is engineered for use with both magnesium and zinc cathodic protection anodes. It minimizes anode-to-earth resistance and helps retain moisture around the anode, resulting in a more efficient ground bed.

The standard formulation contains 75% gypsum, 20% bentonite, and 5% sodium sulfate, while an alternative blend of 50% gypsum and 50% bentonite is available upon request.

This product is offered in 50-pound bags.
