Concrete driveways--joints? - hotinhawaii - 03-05-2011
Anyone have experience pouring or having a concrete driveway poured? I am specifically wondering about the need for stress joints in a driveway on a slope and is about 80x10'. Do there have to be joints or at least scored lines? How often? How deep? Is it standard practice to do this?

Concrete will naturally crack in roughtly square sections; the joints are put in to control the locations. Since your driveway is 10' wide, you would tool joints every 10', to a depth of approximately a 1/4 of the concrete thickness.

An 80X10, it's not IF it might crack, but WHEN. Ours is scored.

4" slab: 9'x9' square.
10' wide: score down the middle and across 8' o.c. 1 1/2" deep. Within 24 hrs. This from a siminar I attended 10 yrs. ago.
