Concrete garage floors in Vaughan
The attached three-car garage is close to standard on Vaughan's newer housing, and the thing that decides how its floor ages is not the concrete mix, it is the joint layout.
A three-car bay is a large uninterrupted slab. Concrete of that size will crack, and if nobody has decided where, it decides for itself, usually diagonally across the area where the cars park. Control joints cut at the correct spacing for the slab thickness and the shape of the bay put those cracks in straight planned lines instead. On an irregular garage, with a bump-out for storage or a side service door, that layout takes some thought rather than a standard grid.
The second issue is salt. Vehicles come home through winter carrying brine and slush and it melts onto the floor. Salt in solution sitting on concrete is much harder on it than salt lying dry outside, and a slab poured flat holds that mixture against the surface and the base of the wall for hours at a time. Pitch toward the door is the fix, and it has to be set at the pour, because adding fall to a finished slab means either a topping that eats headroom without draining properly or removing the floor entirely.
Many of these garages have living space above them, which changes the priorities at the edges. Perimeter insulation and the slab detail matter more there, because the complaint that eventually arrives is a cold floor in the room above rather than anything about the garage itself.
Coatings are worth having on a sound slab, and on a large visible floor they make a real difference to how the space feels as well as how easily it cleans. They need moisture testing first: a coating applied over concrete still pushing vapour upward lifts from below, and no amount of surface preparation prevents that.
Thickness follows use. Four inches over a properly compacted base handles cars. Six is right where a hoist or a workshop is planned, and on these garage sizes that request is common.
In the newer subdivisions the garage slab was usually poured with the house, on fill placed during the build. Where that fill went in quickly and was not compacted in lifts, the floor settles over the first years and cracks along whatever line the settlement takes, which is the common complaint on a fifteen-year-old house here rather than frost.
We also pour the driveways that feed these garages and the walkways beside them, and cover the rest of our Vaughan service area.
North of here the garages are often detached estate buildings with their own servicing, covered on concrete garage floors in King City. Further out the rural shops carry equipment rather than cars, dealt with on garage floor concrete in Caledon.
