Concrete Contractor in Edmonton

Driveway replacement Edmonton homeowners put off usually reaches a point where patching no longer helps: the surface is spalling, panels have heaved or dropped relative to each other, or a crack has opened wide enough to take water straight into the base. At that point replacing costs less over time than repeatedly repairing.

A replacement is mostly excavation. The old slab is broken out and hauled away, the subgrade is dug down and any soft clay removed, then granular base is placed and compacted in lifts to a depth that will not settle. Reinforcement goes in, the pour is formed to fall away from the garage and the house, and control joints are cut so the inevitable cracking happens in a straight line where nobody notices it.

What drives the cost is rarely the concrete itself. It is access for the equipment, the volume of material coming out, how far a truck can reach, whether the existing base has to be rebuilt, and the disposal. A driveway off a tight rear lane with mature trees is a different job from one on an open corner lot, and the quote reflects that.

A concrete sidewalk has to shed water, sit flat through frost, and match the elevation of whatever it meets at both ends. We pour residential walkways and steps, commercial sidewalks and pathways, curbs, gutters and the curved poured edging that separates turf from planting beds and keeps the whole landscape crisp.

Frost heave is the enemy of narrow flatwork. A walkway is light, so it moves more readily than a driveway when the ground under it lifts. Getting the base right — good granular, compacted, drained, with soft material removed — is what stops a path from turning into a set of mismatched steps after a couple of winters.

One caution worth knowing before you plan the work: the sidewalk, boulevard and curb crossing in front of a property are typically in the road right-of-way, which is public land rather than yours. Work that touches them generally needs approval from the municipality, separate from anything on your own lot. Requirements change, so confirm the current ones with the City before you book — we will tell you when a job crosses that line.

A garage pad carries concentrated loads, gets dragged with salt and slush off a vehicle all winter, and sits on ground that heaves. It needs the thickness, the reinforcement and the base to match, and it needs to be sloped so meltwater running off a car in March leaves the building instead of sitting against the sill plate.

On the commercial side we form and pour structural slabs, columns, pads and foundations, and finish them with a power trowel to the flatness the use requires. Slabs that will carry equipment or traffic are specified differently from a residential floor, and the reinforcement, thickness and joint layout follow the engineering rather than habit.

Foundation and footing work is tied to frost depth. In central Alberta the frost line runs well below a metre, and footings placed above it will heave. We dig to the depth the design and the inspection call for.

The comfortable concrete season here runs roughly April to October. Inside that window the ground is thawed, ambient temperatures let concrete hydrate at a normal rate, and curing is straightforward. It is also the busiest window in the region, so booking early in the season gets you a better date than calling in August.

Pours outside that window are possible but they are a different job. Cold-weather work means heated water or accelerators in the mix, ground thawing before placement, hoarding and insulated blankets over the slab, and monitoring so the concrete reaches strength before it is allowed to freeze. Concrete that freezes in its first days loses strength permanently and no finishing repairs it. We will tell you honestly when a late pour is worth doing and when waiting until spring is the better call.

For exposed flatwork we specify air-entrained concrete. The entrained air gives freezing water somewhere to expand into, and it is the single most important thing separating a driveway that still looks good in a decade from one that is flaking by year three.

New concrete needs a first winter of care. De-icing salts are hard on any slab and hardest on a young one, so for the first winter keep them off entirely and use sand for traction instead — it does the same job for grip without attacking the surface. After that, use the least aggressive product that works.

Sealing is worth doing on exposed flatwork and worth repeating. A sealer slows water uptake, which is what makes freeze-thaw damage possible in the first place, and it also helps with the staining that comes off vehicles.

Concrete cracks. Every slab does, everywhere, and in a climate with this much thermal movement it is guaranteed. What good work controls is where: joints cut at the right spacing and depth give the slab a place to relieve stress in a straight line. A hairline crack at a joint is the system working, not a defect.
