[QUOTE="Parks 788, post: 3590058, member: 14646"] I'll be the guy that says to do it. You all sure 3500 psi is the standard? I thought 3000 was the standard. I'm always one to go a little bigger, a little heavier, a bit more HP and cubic inch, a bit more capacity, etc. this hold true with building and construction if it makes sense. On a concrete driveway? Yep. Personally I'd make him do the 4k psi concrete with 1/2" rebar as well as make them put in the 6x6 10x10 welded wire mesh also known as remesh. And I'd make them put them up on concrete dobies. None of this lay it on the ground and using a hammer to pull it up into the concrete once the concrete is poured. Guys that do that would be off my project in a heartbeat. There are two guarantees with concrete. 1) it's going to get hard and 2) its going to crack. Your goal and the contractors job is to mitigate the cracking as much as possible. What is the soil like under the driveway? Compacted properly? lots of clay soil? how is drainage of rain runoff? Lots of factors play into keeping a concrete driveway structurely sound and going a bit extra on the reinforcement is the way to do it. [/QUOTE]
