Good concrete, properly installed, doesn't crack. If that's so rare as
to be moot, then fine. But expecting cracks is lowering your
expectations to that of the ignorant and apathetic masses.

Well, I don't get it. If you concede that even properly installed
concrete usually develops some minor cracks to the point that it's so
rare to find uncracked concrete that it renders it moot, then how can
you turn around and say it's ignorant to lower your expectations?
I'd say you are just being totally unrealistic.

Say a contractor pours a basement slab and a year later, there is a
foot long hair-line crack in one corner. Is that unacceptable and
what exactly would you do?

Also, the fact that you have a 40 year old slab doesn't make the
statement that all concrete EVENTUALLY cracks false. You obviously
have a probablisitic distribution, where some cracks early and the
exceptional case may go a very long time. Yours could crack at 41
years or 100 years, but I'd say it's almost certain to crack
eventually.







I recently looked at a house for sale, with a very large concrete patio..
IIRC the house was built in the 1940s or so. There isn't one crack in
the patio. Not one. Not even a tiny, hairline crack, anywhere.

Thank you!

I was going to post something to the same effect but figured nobody would believe me.

The house I grew up in was built in the 1940's too. *I lived there from 1966 to the mid 1980's.
Basement floor and garage floor were both concrete and had nothing that even resembled a crack.
Both were nice and flat and level too.

Even more amazing: when my mother sold the house in the late 1990's, the house still had its
original water heater!
