Subgrade on lakebed clay
The glacial and lakebed clay under most Chicago lots holds water and heaves when it freezes. We dig down, compact, and lay a free-draining base so the slab sits on something stable instead of saturated soil.
A backyard patio that earns its keep three seasons a year and survives the fourth. Built on a drained base over Chicago's heavy clay, air-entrained for the freeze-thaw, and sealed against the salt that rides in off your shoes and the alley.

Credibility comes from how it's built, not from promises. Here's the order of operations on every concrete patios job.
The glacial and lakebed clay under most Chicago lots holds water and heaves when it freezes. We dig down, compact, and lay a free-draining base so the slab sits on something stable instead of saturated soil.
Every slab gets pitched away from the house and the foundation, so spring melt and summer downpours run off rather than pooling, soaking the subgrade, and refreezing under the edge.
Concrete here lives through dozens of hard freeze-thaw swings a winter. We use an air-entrained mix, with microscopic air pockets that give freezing water room to expand, so the surface resists scaling.
Joints are laid out on a plan, giving the slab clean lines to crack along when it moves with the swing from January cold to August heat.
We let it cure on schedule so it gains strength evenly, then seal it. The seal is the front line against deicing salt and the meltwater that carries it.
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 lakebed clay.

Flatwork in the Chicago area tends to run above the national average, and there are real reasons: air-entrained mixes for the freeze-thaw, footings carried below a deep frost line where they are needed, and extra base work over clay that heaves. The biggest cost drivers are square footage, the finish you choose, and how much the soil forces us to do underneath. We will not quote a patio over the phone; we price it after we have walked the yard and know what the base needs, so the number is one we can stand behind.
A standard residential patio sits on four inches of concrete over a compacted base, which handles foot traffic and furniture fine. Where something heavier is going on, a hot tub for instance, we thicken the slab and add reinforcement for that spot.
Clay is the usual culprit behind heaved slabs around here. It swells with water and lifts as it freezes, so we deal with it at the base: excavate, compact, and build on a drained subgrade, then place control joints so any movement follows the lines we cut. We cannot promise concrete never moves; we build so we decide where it does.
Concrete needs to cure above freezing, so deep-winter pours are limited and call for blankets and frost protection when we do them at all. We will tell you honestly whether it makes sense to pour now or to put you on the spring schedule. We are not going to lay a slab in conditions that shortchange it.
Broom is the practical choice: textured, with traction underfoot when it is wet or icy, and easier on the budget. Stamped reads like stone or slate and looks great, but it needs resealing more often here because salt and meltwater are tough on the finish. We will weigh both against how the space gets used.
Yes. We set the pitch so melt and storm runoff shed off the slab and away from the house rather than collecting on it. Water that sits and then freezes is exactly what chews up edges and opens joints.
You'll hear back from a real person, usually the same day. No call center, no runaround, no chasing us down.
