Concrete Patio Replacement in Topeka, KS
Topeka Concrete Pros replaces worn and broken concrete patios for homes in Topeka and throughout Shawnee County, Kansas. We are a licensed and insured concrete contractor. When a patio has tilted, cracked, or started shedding water back toward the house, we tear it out and repour a new slab on a compacted base: reinforced, air-entrained, jointed, and pitched to drain away from the foundation. You choose a plain broom finish or a stamped and colored surface.
The new slab is four inches of 4000 PSI air-entrained concrete over four to six inches of compacted crushed stone, reinforced with wire mesh or fiber and saw-cut with control joints. Air entrainment builds in microscopic voids so freezing water has room to expand instead of flaking the top. We pitch the patio about a quarter inch per foot away from the house. A slab poured flat on bare clay, with no base and no pitch, is the one that heaves and tips and pools.
Why Topeka Patios Heave
The clay is the reason. Northeast Kansas sits on expansive clay that takes on water and swells, then dries and shrinks back through a hot summer. A patio poured straight on that clay rides up and down with it, and the corners crack first. Freeze and thaw works the same slab from the other direction all winter. A compacted crushed-stone base breaks that grip and lets water move through instead of collecting under the concrete.
Broom Finish or Stamped
A broom finish is the workhorse. The light texture grips underfoot when the slab is wet and it hides nothing under a coat of sealer. A stamped and colored surface presses a pattern into the same reinforced slab, so you get the look of stone or brick over a poured base. Both start with the same structure below the finish. We can carry a stamped pattern out to a matching walkway or pool deck if you want the whole area to read as one.
Slope, Joints, and the House
Where a patio meets the house, an isolation joint lets the two move on their own so the slab does not push against the foundation. Control joints across the field give the concrete a planned line to crack along. And the pitch has to be right, because a patio that drains toward the wall is a patio that feeds water where you least want it. We set all three before the pour, not after.
What It Costs
A concrete patio replacement in Topeka runs about $3,500 to $9,000. A plain broom-finish slab on flat ground sits low. A larger patio, a stamped and colored finish, or a heavy tear-out over an old slab sits higher. Every patio gets a free written estimate first, and if the old slab needs to go, we handle the tear-out and haul-away in the same visit.

Why does my patio pull away from the house and tilt?
The ground under the edge settled or the clay under it swelled and dropped. A patio poured on loose backfill against the foundation moves separately from the house, so a gap opens and the slab tilts. When that tilt sends water back at the house it becomes a real problem. We repour on a compacted stone base and pitch the slab away, so it sheds water instead of holding it against the wall.
Can you match a stamped patio to my house?
Yes. A patio is the flatwork people spend the most time looking at, so it is where a stamped pattern and a color earn their keep. We pour the same reinforced, air-entrained slab underneath and stamp the surface before it sets. A plain broom finish costs less and grips well underfoot, so we walk you through both before you decide.
Should I repair my cracked patio or replace it?
A single tight crack in a sound slab can be sealed. A patio that is cracked in several places, tilting, or flaking across the surface is telling you the base underneath moved. Patching the top does not fix the ground below it. Replacement pulls the slab, rebuilds the base, and pours new concrete that sits level and drains.
How thick is a concrete patio slab?
Four inches over a compacted crushed-stone base is standard for a residential patio. What matters as much as the thickness is what the slab sits on and how it is jointed. We compact the subgrade, set the stone base, and saw-cut control joints so the slab cracks along the joints instead of across the open surface.
