Maintenance Free Carbon Back Fill Earthing Compound Powder (25 kg Bag)

A backfill earthing compound is a conductive material used around an earthing (grounding) electrode to lower and stabilize earth resistance, especially in poor soil conditions. What it does Improves conductivity between the earth rod and surrounding soil Reduces soil resistivity, giving a more reliable ground Maintains moisture around the electrode Protects against corrosion (for approved compounds) Common types Bentonite-based Natural clay, swells when wet Eco-friendly and widely used Performance depends on moisture Carbon / graphite-based Very low resistivity Stable over time Good for dry or rocky soil Chemical / conductive cement Sets hard like concrete Permanent, low maintenance Used in substations and critical installations Typical properties (may vary by brand) Resistivity: < 0.12–0.5 ohm-m (low is better) Non-corrosive to copper and steel Non-toxic / environmentally safe Long service life (10–25+ years)
