Concrete Patios & Outdoor Spaces in Gardner, KS

A concrete patio in Gardner lasts when the base is built for the rock underneath it. Across much of town limestone sits only a few feet down, and water can't drain through stone — it perches on the shelf, saturates the base, and in a freeze it pushes the slab up. We build a compacted base to drain that water and pitch the slab for positive drainage.

That's the opposite of the settling most people expect. On deep soil a patio drops; over shallow limestone it heaves, lifting in wet freezes and easing back in dry spells. Gardner grew up where the Santa Fe and Oregon trails split at Gardner Junction, and the same firm ground that carried wagons now sits close under a lot of backyards. We read how deep the rock is before we quote, because a patio off Olathe's deeper clay-loam and one over Gardner rock need different bases. If your slab is only worn, our resurfacing may carry it.

Heave is a water problem before it's a freeze problem. If roof runoff and yard water collect where the rock is shallow, they have nowhere to go but into the base, and that trapped water is what lifts a slab when it freezes. We set the threshold elevation a step below the door and grade the whole patio to carry water away from the house and off the shelf.

A steady positive drainage pitch — about a quarter inch per foot — moves water to open ground before it can pool. On a rock-shelf lot we pay as much attention to where water leaves as to where the slab sits, because the two together decide whether it stays flat through a Kansas winter.

Where your downspouts land matters as much as the slab pitch. We carry roof water past the edge of the patio so it doesn't feed the shelf right where the base sits. On the commercial aprons we pour over this same southern-Johnson rock, the drainage plan is what separates a lot that lasts from one that heaves in its third winter — a backyard patio is the same problem at smaller scale.

The finish is where a patio stops being gray concrete and starts being an outdoor room. Most Gardner yards come down to a broom vs stamped finish: a broomed top is clean and slip-sure for a family space, while a stamped surface carries a stone or plank look. We pour a mockup first so you sign off on color and texture on the ground, not from a brochure.

We plan the joints as part of the look. Joint pattern continuity — lining control joints up with the door, the posts, and the stamp pattern — keeps the finished slab reading as one designed surface instead of a field of panels. You can see the range of finishes we pour in our gallery.

A stamped surface holds its color when the sealer can breathe. We plan a light reseal every couple of years so the pattern keeps its depth instead of fading flat under an open Gardner sky, and we walk you through the upkeep before we leave.

A ground-level patio generally falls under the City of Gardner's accessory-structure rules, while anything attached or covered pulls a fuller review. We pull the permit, keep the slab off the setbacks and easements, and check that the positive drainage carries off your lot rather than onto the next one.

We build across southern Johnson County, so whether you're near Spring Hill or out toward De Soto, we match the base to the ground — and Gardner's shallow limestone is its own case. Start on the main concrete patio page to see how we approach a build.
