Slabs That Stay Flat Under Load
Concrete slabs and garage floors carry weight that just sits there: cars, workbenches, sheds, hot tubs and air-conditioning units. In Joliet, many older homes on the east and west sides have detached garages, and their floors are often cracked, sunken or tipped toward the door. Newer lots add shed pads, side parking and equipment slabs. Each one needs the right base, thickness and reinforcement for what it holds.
Detached garage floors
A garage floor has to carry vehicles, shed meltwater and slush toward the door, and meet the driveway without a lip. HomeGuide's slab guide lists a two-car garage floor of 400 to 576 square feet at $2,400 to $6,900 installed, typically 4 to 6 inches thick and reinforced. Replacing a floor inside an existing garage takes careful demolition and limited truck access, which we plan for at the estimate. We slope the floor toward the door, set an isolation joint at the walls, and tie the floor to the apron so they move together.
Shed pads and small slabs
HomeGuide puts a 100 to 400 square foot shed foundation at $600 to $4,800, usually around 4 inches thick. A shed pad still needs a compacted stone base, a little slope so water runs off, and a size a few inches larger than the shed on every side. We also pour pads for trash cans, air-conditioning units, generators and grills.
Base, steel and vapor barrier
We remove soft soil and compact crushed stone in layers under every slab. HomeGuide notes that large slabs and foundations may use wire mesh, rebar, a vapor barrier and thicker edges. For garage floors we use mesh or rebar depending on size and load; for an insulated or heated space a vapor barrier may go in under the concrete.
Permits and planning
In Joliet, the city's permit page lists garages among the projects that need a plat of survey for permitting, and a new garage or a large slab may need a building permit beyond the flatwork permit. Rules for sheds and accessory buildings also vary from town to town in Will County. We check what your address needs and include it in the schedule.
Cure times
HomeGuide's slab guide says foot traffic is fine after 1 to 2 days, vehicles should wait 1 to 2 weeks, and full cure takes 28 to 48 days. For a garage floor, we give you a date to move the car back in and a date before which no heavy equipment or epoxy coating should go on.
Coatings and finishes
A smooth troweled finish is standard for garage floors because it is easy to sweep. If you plan to coat the floor later, let it cure fully first. HomeGuide lists epoxy over a garage floor at $4 to $10 per square foot extra.

Concrete Slabs & Garage Floors Questions
How thick should a garage floor be?
HomeGuide lists two-car garage floors at 4 to 6 inches, typically reinforced. We go thicker where heavy trucks or equipment will park.
Can you replace a garage floor without tearing down the garage?
Usually, yes. We break out the old floor in sections, remove it and pour a new one inside the walls. Access and the condition of the walls and footings affect the plan, so we look first.
Does a shed pad need reinforcement?
HomeGuide notes most shed slabs are about 4 inches and typically do not need reinforcement. We still put down a compacted stone base so the pad stays level.
When can I park in my new garage?
HomeGuide's slab guide says to wait 1 to 2 weeks before driving on a new slab. We give you a date based on the mix and the weather.
