Chemical Earthing is use of bentonite based or graphite based compound along with earthing electrode (a pipe or a rod) that helps in improving soil condition and reducing the soil resistivity.

Chemical Earthing electrode provides a low-impedance ground in locations of high soil resistivity. Together with Reslow Grounding Minerals, the system dissipates lightning energy and other dangerous electrical fault currents, even in sandy or rocky soil conditions.

Prime contents include bentonite, graphite, aluminium silicates and metal powders.

Bentonite is a clay which is mined and known for its’ water retention capacities. Other components are conductive in nature.

Chemical Earthing (Grounding) is used when soil conditions leave a less than acceptable conductivity for safety. Salt is one method of increasing the conductivity of the ground. Many radio amateurs use the method for their antenna structures, especially in rocky areas where good earth contact is limited.

Normally, it is not required and when used, it requires replenishing from time to time as rainwater and other natural processes deplete it.
