What's the difference between earthing and bonding? That's a question our readers and clients ask often. Also, we're asked quite a bit about earthing and bonding in general. So, there’s an unusually large amount of confusion around the term Earthing and Bonding. Or, for our friends in the states; you might come across the term grounding and bonding.
Therefore, in this piece, I aim to clarify the difference between - what is Earthing and what is bonding and whether there is a difference.
Breaking things down into simple terms; Earthing - grounding can mean all things to all people. Hence, it is more realistic to think of Earthing as the ‘electrode’ itself. Also, known as the Earth Termination. This reference refers to the physical hardware, such as the copper conductors, rods, etc., that sits buried directly in the geology itself. Read More
Ground testing is typically performed in two stages. The first is conducted during the construction of a building to ensure proper installation of the electrical system and the second stage involves routine ground testing to ensure the 'actual' arrangements perform as the 'predicted' ones at design stage to avoid costly and fatal errors.

Ever been caught in a project meeting and started to think -"what am I doing here?... I hope he/she doesn’t ask me a question. I wish I had found that training course in earthing!"
It's a disconcerting feeling being ‘out of your depth’ or not even in the right ballpark. How are you going to save face?… I know, nod a few times in the right places and maybe ask an open question back, or better still, side-swipe it to a colleague; “what do you think, Stan?” - then run away and hope no-one notices. Did it work? Yes, phew! Great save…Read More
We like to think electricity has been around for years, right? It certainly 'feels' like we should know all there is to know. But as an earthing designer. The scientific community tells us we humans are not good at time perspective that falls outside our immediate field of vision. No surprises here. But, Read More
"Working with GreyMatters has totally changed my expectations of a professional engineering consultancy firm … for the better! Technically, they were on the money! More importantly however ... they kept me updated throughout the entire project, which was so refreshing, and therefore quickly put my mind at ease that things were being taken care of." (C. Turgis)
