I am thinking about hiring a concrete company to redo out driveway and
other concrete work. What I really want is that the driveway should
stay level and crack-free for years, as cracks seriously nterfere
with my material handling. How would I ensure that? Is that a matter
of putting more gravel, more concrete, different concrete, or what?

thanks

short answer: good base, 6" thickness & crack control joints every 150
sq ft

prep is more important than mix but a low water ratio & a decent amount
of cement in the mix help (3000 psi min)

I like rebar or mesh but lots of people (more expert than me) don't.
think it's necessary
