Overview
We also process BFC (back fill compound). BFC is a composition of Bentonite Powder and Graphite Powder at 70:30%, 60:40% ratios or as per your needs.
Graphite – basically carbon, graphite assists conductivity, again to enhance conductivity & resistivity. When added into the soil, back filling retains 350 to 500% moisture of the total volume. With less than 0.40Ω/cm resistivity between the mineral compounds makes it ideal especially for dry and rocky soil belt.
