Fiberglass re-bar? Or Fiberglass mesh/screen?

???? They likely meant glass fiber additive, as a replacement for rebar,
not actual rebar made of fiberglass. Used mainly in light slabs like
patios, garages, and warm-climate driveways. I suppose it reduces prep
labor, but I'm old fashioned and not sure I'd trust it as a replacement
for 4" fabric.

The Stone Slab Floor Setters union thought the same thing when that
new-fangled fake stone - concrete - was introduced. ;)

Learn something every day on here- I did not know that they were making
that now. (I may have grown up in the business, but I haven't actually
been in it for several years.) Thanks for the link.

No friggin' way. That simply means that virtually any cement highway
in NY, NJ, or MI is suspect! They are all full of holes!

(I remember reading a few months ago about the city of NY digging up a
location and finding a bunch of bodies: a mafia graveyard, apparently,
with little hope of ever identifying those burried in the hole!)

Regardless we all know Jimmy Hoffa is alive and well, living with
Elvis in North Dakota.
