Wow. I don't want to make a definitive 'pronouncement' as I am not a
contractor or inspector, but I agree with not using it over poured
concrete, or concrete block walls. Hopefully soeone who knows this
stuff will reply.

Incidentally for people building new homes, the installation of the
Tyvek is frequently done incorrectly. Builders do this because they
know the buyers are generally naive, and builders want to cut corners
as much as they can. Perhaps not all builders, but somewhere upwards
of 90% of builders around here will do anything to speed things up as
long as the inspection goes through.

A proper Tyvek is done in as few separate sheets as possible, carefully
folded and joined at the seams with special fasteners. It should be
sealed to form a bond around all window and door openings. They build
a lot of new houses around here and the Tyvek jobs generally look
atrocious. They even screw up commercial buildings, some chain
steakhouse went in a couple miles down the road, and they just tacked
up Tyvek all over the place, with no folded seams, and seemingly as
many cuts as possible. It of course was bricked over with the Tyvek in
that condition, making mold much more likely.

Tyvek is like wall-to-wall carpeting, you want as few seams as possible.
