What is Chemical Earthing? | A Complete Guide

What is Chemical Earthing?

Hello friends, in today’s article we will see what Chemical Earthing is how it is done how much it costs, and much more about it.

What is Chemical Earthing?

Chemical earthing is an earthing in which we use chemical powder instead of salt and coal. Salt and coal are placed on top of the electrode in any ordinary earthing. When the chemical earthing is done, the chemical powder is placed over the electrode.

Two types of powders are used in chemical earthing. One is Carbon powder and the other is Bentonite powder. Carbon powder is black in color while bentonite powder is brown in color. Earthing with carbon powder is used in a normal place while earthing with bentonite powder is used in a dry place.

Where Chemical Earthing is Used?

Chemical Earthing We can also use for home Chemical Earthing can be used everywhere like home, shop, company, etc. But with some exceptions, only chemical earthing is done and salt and coal earthing are not used in such a place. As in mountainous areas, only chemical earthing is done.

In a nutshell, such earthing is used where there is low humidity.

The Material Used in Chemical Earthing

Many materials are used while doing chemical earthing, the names of the main 7 of these materials are as follows:

  • Earth Electrode.
  • Reducing socket.
  • Funnel.
  • G.I. Nut.
  • Carbon powder/Bentonite powder.
  • S.W.G. Copper Wire (S.W.G copper wire).
  • Wire mesh.

How Chemical Earthing Done?

How Chemical Earthing Is Done?

A deep pit is first dug by an electrode for chemical earthing. After digging the pit, a little bit of water is sprinkled in it. The pit is then filled with 40% to 50% chemical powder and the electrode is properly set. The end of the electrode is kept a little out of the hole so the reason for keeping it out is that the earthing wire can be easily attached to it.

The remaining pit is then filled with chemical powder, after which the earth wire is connected to the reducing socket of the earth electrode. The reducing socket has new welding that we attach to the earthing wire. Your Chemical Earthing is ready which we can start using in the next 2 to 3 days.

What is the Cost of Chemical Earthing?

Chemical earthing depends on how deep the pit is. If you do this earthing yourself, the cost can be reduced.

The cost of the chemical earthing electrode is also around 2000 to 3000 thousand but if we buy the Gi electrode it is much cheaper compared to the copper electrode.

According to this, if we make earthing ourselves, this work can be done in 7000 to 8000 thousand, but if you do today’s work by a company or a professional, it can go from 10000 to 12000 thousand.

Advantages of Chemical Earthing:

The benefits of Chemical Earthing are as follows:

  • Reduces the resistance of the soil.
  • It does not need water like earthing like salt and coal so it is also called maintenance-free earthing.
  • Chemical earthing life is longer.
  • It gives us stable earth resistance in all seasons.

  1. for do the chemical earthing
    1.how much depth required to lay the electrode ?
    2. is it same depth for GI, copper, or may get varied?
    3. shall it can be be covered permanently with slab once done?

    • A depth of at least 1 meter is required for laying the electrodes.

      For galvanized pipe and plate these different types of depth are required. Various types of galvanized pipe are available in the market from 6 feet to 12 feet easily. What matters most is what you want to do Earthing for.

      No, if you want to make it a slab, you can make it a permanent slab, at least one foot below its top height, but be careful not to forget to install a pipe to add water periodically to keep it moist. .

  2. For a conventional earthing pit size 600 x 600mm, you have to make a pit with a width of atleast 750x750mm and a depth of 2mtr depending upon your watering pipe size.
