Concrete Driveway & Walkway Installation in Markham

We pour concrete driveways, walkways, steps, and garage slabs across Markham — from the heritage streets of Unionville and Cathedraltown to the newer builds in Cornell, Berczy, and Greensborough. Every Markham concrete job we deliver is engineered to OBC frost depth, poured to Markham Engineering apron specs, and finished to last 30+ years against road salt and freeze-thaw.

Concrete Services We Install Across Markham

Markham driveways range from narrow Unionville heritage frontages at 12 feet wide to triple-car Cathedraltown approaches over 30 feet. We size every pour to the lot and the bylaw. Our Markham concrete scope covers:

• Concrete driveways — 4-inch broom-finish standard, 5-inch for triple-car or RV loads, fibre-mesh or rebar reinforced.
• Walkways & front paths — 4-inch slab on compacted Granular A, control joints every 4 feet.
• Stamped concrete — slate, ashlar, cobble, and wood-plank patterns with integral colour and antiquing release.
• Exposed aggregate — Canadian Shield, river-wash, or local Markham granite finishes.
• Concrete steps & porches — poured monolithic with frost footings to 1.2 m.
• Garage slabs — 5-inch with 10M rebar grid, vapour barrier, perimeter insulation for heated garages.

Markham Permits & Bylaws We Handle

Markham concrete work is tighter than most GTA municipalities. We pull the paperwork so you don’t have to chase Civic Centre desks:

• Driveway Apron Permit — Markham Engineering requires a Right-of-Way (ROW) permit for any concrete that crosses the municipal boulevard onto the curb. We submit the site plan and post the deposit.
• Tree Preservation By-law 2023-164 — protects the root zone of any tree over 20 cm DBH. We hand-dig within the critical root zone and use root-bridging slabs when the driveway runs near a regulated tree.
• Site Alteration By-law 2011-232 — triggers when fill or grade changes exceed thresholds. We grade to match existing drainage and document soil movement.
• OBC frost depth — all footings for steps, porches, and garage slab thickenings are taken to 1.2 metres below finished grade.

Our Markham Concrete Process

Concrete fails when the base fails. We do not pour onto disturbed subgrade or thin gravel. Our standard Markham build:

1. Saw-cut & demolition of the existing driveway, hauled off-site same day.
2. Excavation to 8–10 inches below finished slab, native soil tested for bearing.
3. Granular A base compacted in 4-inch lifts with a 1,000 lb plate.
4. Forming & reinforcement — 2×6 forms, fibre mesh or 10M rebar grid, isolation joints at the garage and house.
5. Pour — 32 MPa air-entrained concrete, 5–8% air, finished by hand and float.
6. Cure — curing compound applied within 2 hours, joints saw-cut at 18–24 hours.

We also handle the upstream dig and grade — see our full excavation services page and our Markham excavation contractor page for site-prep jobs that go beyond the slab.

Typical Markham Concrete Project Costs

Pricing depends on demolition, grade, and finish. Ballpark ranges we quote in Markham:

• Standard broom-finish driveway: $14–$22 per square foot installed.
• Stamped concrete driveway: $22–$32 per square foot.
• Exposed aggregate: $20–$28 per square foot.
• Concrete walkway (4-inch): $16–$24 per square foot.
• Garage slab with rebar: $15–$20 per square foot.
• Front steps (3-tread, frost footings): $2,800–$4,500.

If you’re still weighing concrete against pavers, compare with our interlocking paver installation in Markham page — both have a place depending on grade, drainage, and resale priority.

Why Markham Homeowners Hire OCM

We are excavation contractors first. That means the base under your Markham slab is built by the same crew that pours the concrete — no finger-pointing when something settles. We carry $2M liability, use only 32 MPa air-entrained mix from local Markham-area plants, and warranty workmanship for 2 years. Every job leaves a clean control-joint pattern, sealed surface, and a site graded to keep water off your foundation.

Frequently Asked Questions

Do I need a permit to replace my driveway in Markham?

If the concrete crosses the municipal boulevard or changes the apron width, yes — Markham Engineering requires a Right-of-Way permit. Like-for-like replacement on private property usually does not require one, but tree by-law 2023-164 and site alteration by-law 2011-232 may still apply. We confirm before any saw-cut.

How deep do concrete footings go in Markham?

Ontario Building Code frost depth in Markham is 1.2 metres. Any structural concrete — steps, porches, columns, garage thickenings — needs footings to that depth. Flat driveway slabs float on compacted granular base and are not footed, but they still need proper sub-base prep to avoid heaving.

How long until I can drive on a new concrete driveway?

Foot traffic at 24–48 hours, light vehicles at 7 days, full strength at 28 days. We recommend keeping heavy delivery trucks off for at least 10 days. Markham winters are hard on green concrete — we will not pour structural slabs below 5°C without insulated blankets and accelerator.

Will my Markham tree by-law affect the driveway?

Yes if a tree over 20 cm trunk diameter sits inside or near the work zone. Markham By-law 2023-164 protects the critical root zone. We adjust slab edges, hand-dig within the root zone, and submit an arborist letter to the City when required to protect both the tree and your permit approval.

Stamped concrete or interlocking pavers for a Markham driveway?

Stamped concrete is cheaper, faster to install, and seamless — but cracks are harder to repair invisibly. Pavers cost more upfront, handle freeze-thaw movement better, and let you lift and reset single units. For Cornell or Berczy resale, pavers usually edge out. For Greensborough rentals or budget-driven jobs, stamped concrete wins.
