re: Welded Wire Mesh in Driveway - Yay or Nay?

Mesh is not used to strengthen the driveway nor will it stop it from cracking. The sole purpose it serves is to keep the concrete slab intact after cracking occurs. If installed correctly with properly placed joints you won't need to worry about future repairs.

Not much point putting rebar in a 4" slab, especially if it is just sitting on the ground with concrete poured around it. If you must, put some wood blocks underneath the rebar or something

Use the WWF, but know future cracking will be controlled by properly spaced expansion joints

A little water never hurts, and don't overfinish the surface

You don't need rebar in a driveway. I highly recommend wwm. It's so cheap and will only benefit the durability of the slab. Do it. Money well spent.

I love all the engineers in this thread

Proper panel geometry?
Good sub base?
Consistent depth throughout?
Using the right concrete mix?

Try to find someone experienced to be there with you when it comes time to order, receive and place the concrete.

Mix in one bottle of light Karo syrup per yard of mud. It'll help with the cracking over time.

No to hijack but how long does it take for a partial driveway to dry? 6 feet by 7 feet maybe.

depends on weather, temperature, thickness, mix and if you put any admixtures in it.

If I want something to dry fast, I usually will order a 4000 mix. Typically has more cement in it than 3000 and will dry a good bit faster. A 6" thick driveway poured with regular 4000 without any kind of high early in it with average temps above 80, I would put a car on it in a couple days and be fine and I usually air on the safe side since I have to sell the stuff. Realistically, same scenario could put a regular car or truck on it after about 24 hours and be fine but longer is better.
