In Reply to: Let me add that I said nothing about chemical grounding. Diatomaceous earth is ground sea shells. nt posted by Norm on July 5, 2006 at 06:46:28:
It constitutes "sea foam" (do you say it this way in english?), this kind of thin white foam you get on beaches on the top of each breaking wave.
The same material was used, once compressed, to make pipes (I mean pipes for smokers).
Since it easily retains water, and is not dissolved if a chemical solution is used (made of quite pure SiO2), I understand you can use it for grounding in granitic areas with massive plain rocks without soil.
I just didn't know South Florida was granitic and houses built there above massive plain rock without soil. Thanks for my learning something.
