Subgrade on lake clay
Chicago sits on heavy glacial and lacustrine clay that holds water and shifts as it freezes. We excavate the topsoil, compact a stone base, and set the slab on stable, well-drained subgrade instead of soft fill.
Turn the back of the lot or the gangway into real living space. A patio poured for Chicago's deep freeze-thaw, pitched to shed meltwater, and cured so it holds its surface winter after winter.

Credibility comes from how it's built, not from promises. Here's the order of operations on every concrete patios job.
Chicago sits on heavy glacial and lacustrine clay that holds water and shifts as it freezes. We excavate the topsoil, compact a stone base, and set the slab on stable, well-drained subgrade instead of soft fill.
The slab is pitched away from the house so snowmelt and spring rain run off rather than pooling against the foundation or freezing into the gangway between buildings.
We pour an air-entrained mix built for repeated freeze-thaw, so the surface resists the scaling that salt-laden meltwater causes through a Chicago winter.
We cut control joints on a plan so the slab has defined lines to move along as it expands and contracts through the big seasonal temperature swings off the lake.
We cure on a schedule so the slab gains strength evenly in the damp lake-effect air, then seal to slow salt and moisture from working into the surface.
Most contractors vanish after the deposit. We pick up the phone, show up when we say, and stand behind the work after the truck leaves. The follow-through is the difference.
A foreman we know runs your job and a vetted crew does the work, managed by Lucky's, one company accountable from the first call to the final walkthrough.
COI and lien waivers on file before we break ground. The documentation that lets commercial clients pay and gives homeowners peace of mind.
Prepped subgrade, reinforced and mixed to spec for the job, and proper curing. We build credibility through the process, not promises. On concrete patios, that starts with subgrade on lake clay.

Concrete in Chicago costs more than the national flatwork average for real reasons: an air-entrained mix that stands up to road salt and freeze-thaw, excavation and a compacted stone base over heavy lake clay, and the tight access most city lots and gangways force a crew to work around. From there, patio price tracks square footage, finish (broom vs. stamped), and how much base work the soil and grade need. We price it after seeing the space, never a low number on the phone we can't stand behind.
A residential concrete patio is poured on a 4-inch slab over a compacted stone base, the standard for foot traffic and furniture, and we thicken it where heavier loads like a hot tub sit on it. On Chicago's clay the base prep under that 4 inches matters as much as the slab itself.
The heavy clay under most Chicago lots holds moisture and lifts as it freezes, which is the leading cause of slabs heaving here. We manage it at the base: strip the soft topsoil, compact a stone subbase that drains, and cut control joints so any movement follows planned lines. We can't promise concrete never moves; we build to control where it does.
Concrete has to cure above freezing, so deep-winter pours in Chicago are limited and need blankets and frost protection to set safely. We will tell you straight whether to pour now or wait for the season, and we won't put a slab down in conditions that compromise it.
Broom is the workhorse: textured, slip-aware in snow and freezing rain, and easier on the budget. Stamped gives the look of stone or brick that suits a lot of Chicago housing, but it needs resealing more often because winter salt and meltwater are hard on the finish. We'll walk both against how you'll actually use the space.
Yes. We set the pitch so meltwater and spring rain shed away from the house instead of pooling and freezing, which matters most in a narrow city lot where a patio, a gangway, and a foundation wall all sit close together. Standing water that freezes is what wrecks edges and joints.
You'll hear back from a real person, usually the same day. No call center, no runaround, no chasing us down.
