Somebody in one of these two groups recently said that a concrete based house means you're earthed. Concrete is a bloody good insulator!

Sorry, can't find the post it was mentioned in.



Wrong as usual. Concrete that's been cured and then dried out,
kept away from moisture, may not be a good conductor. But building
concrete, a foundation is such a good conductor, it's the preferred
ground for the building electrical service. An electrode is placed
inside it before the pour.

Only if the concrete stays wet. Which won't happen unless it rains a lot.

This was originally designed for ammo dumps in the desert so try
again.

First time I've seen ammo dumps mentioned. We're talking about houses, concrete floors, and the dangers of being earthed.

The danger is not being earthed when you are talking about ammo and
this was the most effective way to earth them.

Where you live, it is always wet isn't it?

Yes, but not inside the house.

The effectiveness is in the contact area, not any single point.

The top surface of the concrete in the house isn't wet. If it is, your carpet would go mouldy.

It is wet enough to ionize the stuff in concrete.
I didn't make this **** up on the spot, google Ufer.
