Concrete Driveways in Kansas City, MO

Most of the concrete driveways failing in Kansas City today were poured in the 1960s and 1970s — and many were undersized for clay from day one. The shrink-swell cycle in KC's eastern Jackson County neighborhoods lifts slabs through summer, drops them in winter, and opens cracks wide enough for water to undercut the base. Once the base is compromised, surface patching is temporary at best. The fix is subgrade stabilization, a proper compacted base, and a 4-inch minimum slab with control joints spaced to match the driveway width.

In Waldo and Brookside, we regularly replace driveways that were poured without adequate base depth — common on homes built from the late 1940s through the 1970s that define those neighborhoods. The slabs come out thin when we break them, and the clay underneath shows the heave scars clearly. New installations in south KC developments call for the same base standards regardless of how recently the ground was graded.

Our KC driveway pours use an air-entrained mix designed for the freeze-thaw cycles this climate delivers. We set drainage slope toward the street, not toward the garage or foundation, and we place control joints at intervals that give the slab room to move without random cracking. Every pour includes a site walk before we schedule, so we are not guessing at soil conditions from the truck.
