Yes, you bring unregulated and unwanted electricity into the building and you
may SEVERELY worsen your earthing. Close lightning strikes energize the earth

being under the building's footprint could mean little to no earthing actually
happens. The 3rd rod should NOT be a replacement of the existing 2 and MUST
only be added to the existing 2 by a jumper conductor...ONLY IF determined to
be needed or beneficial.

This addition or by driving your existing rods deeper, is the ONLY way to
reduce your resistance. But, what is your current resistance? If you're
already at very low resistance, then you likely can't make it any better
because you're down to the conductor's own resistance. Don't do anything
unless and until you know what your resistance is. More rods IS NOT better and
WILL only extend your reach to pick up static electricity, fallen power-line
or lightning energy...a deeper single rod is factually best.

You sure do talk cobblers
