I am going to be helping a fried widen his driveway. The part we are going
to be adding will be about 48 feet long and 6 feet wide. He wants to pour it
4" think, since that is what they rest of his driveway is. Do we need to use
rebar, or can we get away with using some 10ga metal mesh?
Thanks for any advice...
Are you parking anything on it? If so I would use the mesh, and drill the
edge of the existing concrete every 8-10 inches 3-4 inches deep and put
some rebar in the holes. 12 inches long Also put a piece of rebar down the
outside edge. Might even do a turndown on the outside edge. Like a shovel
width and inch or two deeper. Never know when your buddy will come over with
the 2 ton truck that is loaded. Certain areas require termite spray when
disturbing the soil. I would use at least 3000 psi concrete. Have fun
6x6/10x10 wwf (re-mesh) is not a reinforcement for concrete. It
serves to keep the cracked concrete together to reduce separation
and uneven settlement. There are some suppliers that contend that
fiber concrete is equivalent to WWF.
Rebar reinforcement raises the strength of concrete if applied
For your driveway job, I would concentrate on subgrade
compaction; thicken the edges with a single #5 bar reinforcement;
and create construction/control joints every 6' to keep the
pavement sections square.
Keep the whole world singing. . . .
