Along with Electrode another key aspect of the grouding system is the backfill compound. Back fill compound enhances the conductivity of the soil around the electrode.
It is a specially developed compound possessing high conductivity, non corrosiveness, moisture absorbing & retaining characteristics for a longer time. It reduces the soil resistivity, helps in faster dissipation of fault current and enables least fluctuation of resistance value without using salt, charcoal, etc. around the earthing electrode. 

The best feature of the   compound is that it is not soluble in water and does not cotaminate the water at all nor it moves away because of the water streams in the grounding pits . It not only improves the safety of the equipments and the mankind but is also safe on the environment
