Hi All
I'm doing a new home installation and struggling to get a good earth.
There is a drought in Cape Town right now and it's not helping
The plot seems to have solid rock everywhere soon as I go more than 1m deep.
I have installed a copper earth mat below the foundation, used lots of bare copper in the Trench to my wc1 box and knocked in two pathetically short earth spikes about 1metre deep.
Resistance is still way out of specification.
Auzzie sparks reckon I should use a jack Hammer to knock down the spikes but I doubt I will penetrate the rock so I am looking at possibly having holes drilled about 6metres x 3 for earth spikes and then filling up with bentonite clay.
However, I'm not sure it's available in South Africa and I'm also not entirely sure who I contact for the drilling. Core drillers?
I have spent most of my time working in industrial panel wiring and earthing is not something I have vast experience in, but I guess it's when you have issues like this that you really become *experienced*
