Concrete Patios in Lee's Summit, MO

Patio failures in Lee's Summit follow a predictable pattern on the Wymore-Ladoga clay formation. Water from the house downspouts, AC condensate lines, or irrigation heads saturates the soil near the foundation. The clay swells, lifts the patio edge nearest the house, then dries and contracts leaving a gap at the house-to-patio joint. Over two or three cycles of this, the patio tilts slightly back toward the foundation — which sends surface water toward the house instead of away from it. Fixing drainage before the pour, not after, is what prevents this sequence from starting.

In Lakewood, where lots often feature moderate slopes and mature landscaping, patios need a clearly defined drainage path to a yard drain, a swale, or the street. In newer developments along the Pryor Road corridors, we often see larger patio footprints requested for outdoor kitchen and covered living setups — those larger slabs need more control joints and careful attention to the aggregate base under the kitchen area where concentrated load and water exist simultaneously.

We slope every Lee's Summit patio a minimum of 1 percent away from the house — ideally 1.5 percent where yard drainage allows. Control joints are laid out on a grid matching the slab dimensions, not cut as a formality after the fact. For decorative finishes, we use the same base prep and drainage standards as plain broom finish — the surface treatment changes, the structural engineering does not.
