Concrete Patios & Outdoor Spaces in Riverside, MO

Riverside sits on the lowest, wettest ground in the metro — Missouri River bottomland kept dry by a levee, not by nature. The water table under a Riverside lot sits high and close to the surface most of the year, so a patio here can't be poured like one on a hilltop. It has to be built to float above that water on a free-draining base, so a downpour or a wet spring doesn't leave the slab riding saturated ground. Build the compacted base right and a river-bottom patio stays level and dry.

This is ground we know at every scale: Ford poured the concrete for Amazon's facility right here in Riverside, on the same alluvial bottoms the homes and townhomes sit on. The concrete patio behind your house needs the same read of the water and the same base discipline as an industrial slab — just sized for a back yard. The rest of this page is how we build one that lasts on the flat.

On most lots, extra water soaks away into the ground. On the Riverside bottoms it can't — the ground is already near saturation, so every drop of runoff has to be moved off the surface and away. Every pad we pour falls about a quarter-inch per foot to open ground — positive drainage that clears a downpour off the slab fast, because on this ground standing water has nowhere to drain and only keeps the base wet.

The door sets the top of the grade. On a back slider or walkout the finished threshold elevation sits a safe step below the sill with the ground falling away, so water never backs toward the house — which matters more on flat bottomland, where there's little natural fall to carry it off. We tie downspouts into a run that daylights well past the slab and, on a level lot, cut a shallow swale so the water actually leaves instead of pooling against the pad.

Riverside's mix of newer townhomes and older river-town homes means a patio is often the main outdoor space, so the finish carries the look. The everyday call is a broom vs stamped finish decision: a broom finish gives a clean, slip-steady surface that wears well, while stamped concrete can pattern the pad to read like stone or plank. On a larger pour we lay the control lines out as a joint pattern continuity so the joints frame the space instead of cutting across it at random.

Before any stamp or color goes down we pour a small mockup so you approve the exact texture and shade against your own house, not off a brochure. On the damp bottomland ground we finish with a breathable sealer so moisture moving up through the slab can escape rather than clouding a trapped film. Our gallery shows stamped and colored patios we've poured across the metro.

Most patios in Riverside need a permit through the Community Development department, and because much of the city sits in the Missouri River floodplain, a project there can draw extra review — elevation certificates and a look at how the work affects drainage. We pull the permit, handle the floodplain step, and lay the drainage out to clear it. A roofed or attached cover over the patio gets a closer read against setbacks and lot coverage.

Riverside sits in Platte County off I-635 and MO-9, so the soil and frost rules are Missouri's — MoDNR guidance and a 36-inch frost depth we carry the footings and the compacted base below. It's a short run northwest for us, and it's ground we've poured on from an Amazon slab down to a back patio — easy to get out, read the water under your lot, and give you a written number before anything starts.
