Geez Curt,
That sounds like the concerete and rebar in a nuclear containment!! When we
installed firewater mods the drill bits didn;t last very long and we went
through a bunch of them for each hole.
On 2nd thought I wonder if the rebar was as thick as you encountered? That
sounds *really* bad! More like steel with a thin coating of concrete!

Scroll down to Presque Isle Air Defense Command and look at the Snark
launch pads. Those were built in '58-'60. They're still there.
A couple years ago Dad's company was hired to figure out what they really
are, all plans of course are top secret. We went up to drill a core
sample, I gave up at 9' of solid concrete that was absolutely FULL of huge
pieces of rebar. You could have built a Kia out of the rebar we took out
of a 3" core hole that was 9' feet long...
Last I knew (spring before last) one of the pads had a firewood processor
sitting on it. The firewood company was concerned they'd break the
concrete. We assured them that wasn't going to happen in our lifetime.

The Government really could spec re-bar to excess - when we built the
Titan2
silos, they used the largest rebar made, 2 1/4" diameter, on 12"
centers
both vertical and horizontal, inside wall and outside wall - and the
concrete was 8 ft thick on the top half of the silo walls. Concrete
was
also "Class A", had to meet 3000 psi compressive strength.
Most house cellar walls I've seen in the last 20 years have been poured
with
cheap concrete between forms and without any wire or steel to keep
cracks
from separating. Most of the time the builder is long gone before too
many
cracks show up, or the owner just doesn't see them or know that it
isn't
"normal".
