Concrete Driveways in Pleasant Hill, MO

Pleasant Hill has two distinct driveway conditions depending on the neighborhood. Established subdivisions built in the 1980s and early 1990s — particularly the blocks west of downtown and the older residential streets near Walnut Street — are producing a steady stream of replacement work. Those driveways went in under base-prep standards that underestimated how aggressively Cass County clay moves through freeze-thaw and wet-dry cycles. What you see now are slabs with sunken aprons, mid-panel cracking, and separation at the control joints. Newer development on the east side of town near the 58 Highway growth areas tends to need wider driveways and better drainage design rather than outright replacement.

Along the older streets near downtown Pleasant Hill and the Walnut Street corridor, driveway aprons often show the most damage first — the zone where the driveway meets the street takes the most load from vehicles and is most exposed to drainage that sheets off the roadbed during heavy rain. That apron area sits on subgrade that has been disturbed repeatedly over decades. When we replace a driveway in this part of Pleasant Hill, we typically find shallow or inconsistent base prep that explains exactly why the previous slab failed.

Every driveway we pour in Pleasant Hill uses air-entrained concrete rated for the KC freeze-thaw cycle, with a minimum 4-inch slab on 4-6 inches of compacted aggregate base. Drainage slope is set at no less than 1.5 percent away from the garage and toward the street or a defined drainage path. Rebar vs. wire mesh is determined during the site walk based on soil conditions at the specific lot, not as a default spec applied uniformly across all jobs.
