Concrete Driveways in Sun Prairie, WI
A driveway is decided at the base, not at the finish. Four inches of compacted dense-graded base goes under residential flatwork, placed and compacted in lifts rather than dumped and rolled once, and the slab runs four inches through the field and five to six inches where vehicles actually sit and turn. Reinforcement is a real choice: #4 bar on chairs where the load or the subgrade calls for it, fiber mesh where it does not, and the estimate should say which. Saw-cut control joints go in within the first day at a quarter of the slab depth, spaced in feet at roughly two to three times the slab thickness in inches, and lined up with the garage door and the approach. Where a driveway meets the street, the approach sits in the public right-of-way and carries its own municipal standards. In newer Sun Prairie subdivisions the subgrade decision matters more than anywhere else on this list, because a driveway on unsettled backfill fails from underneath no matter what the surface looks like on day one.
