Concrete garage floors in Caledon
In rural Caledon the building people call a garage is often a working structure, and pricing it like a residential slab is how it fails early.
A drive shed, a workshop or an equipment barn carries loads a car never approaches. A tractor, a loaded trailer, a vehicle on a lift, a compressor and a bench along one wall. That is a structural slab, and it is specified from the loading: thickness, reinforcement, sub-base and joint layout all follow from what will actually be on the floor. Six inches over a properly built base is the starting point rather than the upgrade, and reinforcement is designed rather than assumed.
If a hoist is planned, its footings go into the pour. Retrofitting a hoist footing means cutting a hole in a floor that was finished and cured, and paying for the same square footage twice.
Wash-down is the second rural requirement. A floor that gets hosed out needs falls and a drain designed into it, and on private servicing the discharge point carries a constraint that the municipal version does not: it cannot be the septic bed and it cannot run toward the well. That is resolved on the drawing rather than on the day.
Cold is worth planning around too. Many of these buildings are unheated, and pouring into them at the wrong end of the season means heat and protection for the cure. Frequently the better answer is to schedule the work for the season rather than fight it with blankets.
In Bolton, on the serviced side, the job is the ordinary residential one. Pitch toward the door so meltwater and road salt leave rather than sitting on the slab, joints laid out for the size and shape of the bay, and four inches over a compacted base for cars.
Coatings work well on a sound, dry slab and make a working floor considerably easier to keep, particularly where oil, fuel or chemicals are part of daily use. They need moisture testing first, because a coating over concrete still pushing vapour will lift from below no matter how well the surface was prepared.
We also pour the driveways that serve these buildings and the walkways around them, and cover the rest of our Caledon service area.
East of here the equivalent buildings are coach houses and equestrian barns, covered on concrete garage floors in King City. South the garages are attached and the issue is joint layout plus road salt, dealt with on garage floor concrete in Vaughan.
