Slabs We Pour
Residential and light commercial slabs, including:
- Garage slabs – tied to foundations or footings, sloped to the door, reinforced for vehicle loads
- Shed and workshop pads – level pads formed square with grades set for the structure
- Addition and sunroom slabs – prepared for framing layouts with anchor bolts and insulated edges where required
- Hot tub and equipment pads – thicker sections designed for concentrated loads
What Makes a Slab Stay Level in Barrie
Excavation and fill
A slab is only as good as what is under it. Topsoil comes off, soft spots are dug out, and compacted granular fill brings the grade up. Pouring over uncompacted backfill is the fastest way to a slab that settles and cracks within a couple of winters.
Thickness and reinforcement
Most residential slabs are poured at 4 to 5 inches with rebar or mesh at mid-slab; garage and hot tub slabs are thicker with heavier grids. Edges and thickenings are added where loads concentrate.
Flatness, slope and finish
Garage slabs drain toward the door; shed pads are crowned or sloped slightly. Finish choice – broom, steel trowel or power trowel – depends on the use. Control joints are laid out to match the slab geometry before the concrete sets.

Common Questions
How thick should a concrete slab be?
Shed pads and walkway slabs are commonly 4 inches; garage slabs and anything carrying vehicles are 5 to 6 inches with heavier reinforcement. We size thickness to the load at the estimate stage.
How long before I can build on the slab?
Framing usually waits about a week for adequate strength in normal weather. Full design strength takes about 28 days; we confirm timing based on the mix and season.
Does a shed slab need a frost footing in Barrie?
Per the City of Barrie residential permit requirements: constructing an accessory structure such as a garage or gazebo over 10 m² (108 ft²), or a detached shed over 15 m² (162 ft²) or taller than one storey, requires a building permit – and those structures need footings to below frost depth per the Ontario Building Code. Smaller free-standing shed pads can often float on the granular base. Unsure which side your project falls on? Service Barrie (705-726-4242) confirms it for your address, and we flag it during the site visit either way.
Can you pour a slab in winter?
Cold-weather pours are possible with heated enclosures, hot water mixes and curing protection – at added cost. Late spring through fall is the practical window for most projects.
