Addition footings, garage floors, basement slab replacements — poured to Illinois frost depth and signed off by the inspector.
A foundation is the only concrete on your property that cannot fail quietly. Everything above it — the framing, the drywall, the finish floor, the cabinets the trim carpenter just installed — assumes the concrete underneath did its job. When a footing heaves, an addition moves. When a basement slab cracks across the middle, the plumber's drain line goes with it. Structural slabs and footings get poured once and have to hold for the life of the house.
We pour foundations, footings, garage floors, addition stem walls, and basement slabs across Schaumburg and the surrounding Northwest Chicago suburbs. Most of our structural work comes in three flavors: new additions where a framer is waiting on the rebar inspection, basement floor replacements after plumbing or drain-tile jobs, and garage teardowns where the original 1960s slab has finally given up. Every one of those jobs gets tied in, spec'd, and inspected before anyone backfills or stands a wall.
Structural concrete is a different animal from flatwork you can walk on and forget about. The loads above are measured in thousands of pounds per lineal foot. The inspector is going to show up before the pour. The framer's schedule depends on us being ready on the day we said we would be. We build that coordination into the quote, not onto the back of a napkin when the truck is already on site.
New garage builds and full-depth slab replacements on teardown garages. Slab-on-grade over compacted CA-6 and a vapor barrier, pitched to the overhead door so melt water and salt brine drain out instead of pooling against the wall studs.
Frost-depth footings and poured stem walls for room additions, sunrooms, three-season porches, and dormer extensions. We drill and epoxy rebar dowels into the existing footing so the new foundation ties cleanly into what's already there.
Full basement slab tear-outs and repours, often after a plumber runs new drain lines or a mason re-does the drain tile. Saw-cut the perimeter, break out the old pour, re-level the stone base, lay fresh vapor barrier, and pour back to grade.
Monolithic thickened-edge pads sized to the structure going on them. Proper gravel base, control joints laid out for the footprint, and a slope off the building line so nobody ends up fighting a dirt dam behind the shed in two years.
Two- to three-inch unreinforced caps over dirt crawls to seal out soil moisture, vermin, and radon. Not structural, but they keep the crawl dry, clean, and usable, and they protect the wood framing above from decades of vapor drive.
Slab settlement repair, cold joint reconstruction, and concrete work on jobs where a foundation repair crew has set helical piers or push piers. We handle the slab and footing tie-ins after the piers are locked in.
Structural concrete is not the place to save money on the parts nobody sees. Here's the spec we run on every footing and every slab that has a roof over it or a load on top of it:
Foundation work in our service area runs from mid-March through late November most years. In that window, ground temperatures are warm enough that a footing can be dug clean, a slab can cure without accelerators, and a basement wall can strip the next morning without frost damage on the form face. Outside the window, we still pour for urgent jobs — additions that got framed late, basement floors that failed mid-winter — using insulated blankets, heated enclosures, and admixtures that keep the hydration reaction running when the air is below freezing. It costs more, and we're upfront about that on the estimate.
Frost depth is the keystone number for everything we pour below grade. A 42-inch footing holds because the soil below that line doesn't freeze. A shallower footing — the kind some crews will still pour on a cold morning to save time on the backhoe — freezes solid every January, lifts, and drops the entire structure above it. Heave damage on a first-year addition is one of the most expensive mistakes in residential construction, and it is almost always a footing-depth problem. The other wrinkle around here is clay subsoil, which is why every slab we pour sits on a rolled CA-6 stone base rather than directly on native grade. Stone gives the slab a consistent platform regardless of what the clay below is doing that week.
Frost depth. Water in the soil freezes and expands, and if your footing isn't below the freeze line it lifts every winter and settles every spring. Cook and DuPage counties have adopted 42 inches as the minimum footing depth for heated residential structures. Garage footings and attached outbuildings go to the same depth. Cutting that number short is how porches and additions pull away from the house after two or three winters.
Yes. A vapor barrier isn't about standing water or snow melt — it's about soil moisture wicking up through the slab. Without one, you get efflorescence on the surface, rust on stored tools, damp cardboard at the bottom of boxes, and a floor that never really dries out. We run 6-mil poly minimum under garage floors and 10-mil poly under any slab that's going to see interior living space. Cheapest insurance policy in a concrete job.
Yes, and it's one of the most common structural jobs we run. The walls stay. We saw-cut the perimeter a few inches off the footing, break out and haul the old slab, re-excavate to subgrade, re-compact the stone base, lay fresh vapor barrier, and pour a new 4-inch slab tied back to the existing footings. Most residential basement floor replacements run two to three days on site once we're inside.
CA-6 is a graded crushed limestone aggregate specified by the Illinois Department of Transportation. It's a blend of sizes from dust up to about an inch that compacts to a dense, stable platform and still drains. Every structural slab we pour sits on at least 4 inches of rolled CA-6 — not pea gravel and not native clay. Sub-base failure is the single most common reason a residential slab cracks in its first few years.
On an addition, the general contractor usually pulls one permit that covers the whole build, and we slot our concrete work inside that permit. On a standalone slab or footing replacement with no framing above it, we pull it ourselves. Either way we handle the concrete inspection calls. The village wants to see rebar and vapor barrier before the truck arrives, and we hold the pour until the inspector signs off.
