i think the guys in alt.building.construction, that
i'm crossposting to, would have more to say on the
topic of concrete driveways and rebar/wire mesh.

i've seen HUGE driveways done with NO rebar at all,
and the surface is perfect years later. And that's
driving all kinds of heavy pick up trucks and trailers
onto it.


The trick to using no rebar in a slab on grade is proper subgrade
preparation. You MUST pour the slab on a properly compacted base. And,
you MUST have a proper layout of crack control joints.

I regularly specify slabs for residential garages and driveways as "5-inch
unreinforced slab on grade on 6" of 3/4" minus compacted gravel base.
Crack control joint every 150 sq.ft."

The only reason to put reinforcing steel in a slab on grade is if the soil
is very poor and cannot be properly compacted.
