This 50 lb Backfill Mix (75/20/5) is a specially blended combination of 75% gypsum, 20% bentonite, and 5% sodium sulfate (SS), formulated to improve the efficiency and lifespan of cathodic protection systems. The gypsum retains moisture, the bentonite ensures compactness and sealing properties, and the sodium sulfate lowers the ground resistance. Ideal for surrounding buried anodes in both impressed current and galvanic systems, this mix promotes consistent electrical conductivity and reduces corrosion potential over time.
