Ufer Earthing

[robertsonmartin]

Hey,

Making plans for a new-build in the future and electrics / earthing always seems to be a hot topic in DIY forum. I recently heard about an earthing system that I hadn't heard of before and it looks like it doesn't get used much outside ofthe US Military / commercial builds.

It is called Ufer Earthing which was named after the guy who came up with it and it uses the steel re-bar foundations to provide the earthing (along with a conventional earth rod for double the protection). Apparently works great in dry ground / sandy soil scenarios where it is difficult to achieve a low resistance reading earth with a normal earth rod.

Here is a link to an interesting read - http://www.psihq.com/iread/ufergrnd.htm ; http://wiki.diyfaq.org.uk/index.php?title=Ufer_Earthing

Seems like a good earthing system to use on a newbuild. Wonder if there are any disadvantages / reasons not to use in Thailand?

Where in Thailand do you have dry ground or are unable to drive a conventional ground rod for a residential electrical installation? If you are building on solid rock and using a concrete foundation, then Ufer grounding may have some merit.
