Aurora Garage Slab Replacement and New Pours

Seven in the morning and the garage is empty. Everything that lived in there is out on the driveway under a tarp. The old slab came out yesterday, so the hole is open, and the first thing our crew does is walk it with a rake and a level before anybody calls the plant for a delivery time.

A garage is the one pour where the room fights you. Three walls, a low header, drywall nobody wants to patch, a water heater in the corner, and a single opening to move every wheelbarrow through. The concrete work is ordinary. The logistics are the job. So we plan the day backward from wherever the truck can safely park.

Demo day comes first, and it sets up everything after

We saw the perimeter before breaking anything. A clean cut along the walls and across the door line keeps the demo from telegraphing into the apron outside or cracking the stem wall behind the drywall. Then the slab comes up in manageable pieces and goes straight to the truck.

What's underneath is why this gets its own day. Sometimes it's clean fill and good base and the schedule holds. Sometimes it's bare dirt, a buried downspout line, or a soft trench where a plumber worked decades back. We'd rather have that conversation with the hole open than with a mixer idling at the curb. Wall bottoms get tarped, the water heater boxed, and we sweep before we leave, because demo dust finds every shelf you didn't empty.

What we need from you before pour morning

• Garage emptied to bare walls, including anything hanging low off the studs
• Both vehicles parked where they won't box in the truck or the crew
• A working exterior outlet and a hose bib we can reach
• Pets kept inside, since the door stays open most of the day
• Anything bolted to the old floor unbolted ahead of time
• A decision made on the door threshold height before we set forms
• Room on the drive for a haul-off trailer

Getting concrete into a room with one opening

Plastic, base, and the layer you never see again

Poly under the slab isn't optional on our jobs. Ground moisture climbs through concrete whether you can see it or not, and a garage floor without a vapor barrier is the one that blooms white every spring, sweats under a parked car, and refuses to hold a coating. The sheet goes over compacted base, laps taped, and we keep it intact while the steel goes down.

Base gets what it would get outside. Road base in lifts, compacted, brought to a grade that already carries the slope we want. An isolation strip goes against the stem walls and around any column so the floor can move a hair without dragging on the structure. Then steel on chairs, tied, riding mid-slab instead of lying on the plastic.

People are surprised by how quiet the pour is and how long the finishing takes. Concrete is in the room by nine. We're still on our knees at four, waiting on the surface to tell us it's ready.The crew lead's read on it

Placing, jointing, and the hours after the truck pulls out

We start at the back wall and work toward the door, screeding to the grade stakes as we go. Slope gets set here, not later. About an eighth of an inch per foot toward the opening carries snowmelt off your car out the door instead of letting it pool at the back wall all winter, where it eventually finds the drywall.

Then we wait. Bull float, then hands off until the bleed water burns away, because troweling a wet surface is how a floor ends up shedding dust for years. Once it firms we finish, usually to a smooth trowel since this floor lives indoors and gets swept. Joints go in the same day.

Timing is friendlier than outdoor flatwork, since the room shelters the slab from sun, wind, and rain. An unheated garage in January is still an unheated garage, though. Cold weather work means mix batched warm, an accelerator that skips the chloride, and blankets over the whole floor. Frozen subgrade stops us in here the same as it would outside. Folks in Saddle Rock and Tollgate Crossing hear the same advice from us: if the timeline bends at all, spring and fall are calmer and the finishing window is wider.
