How much does it cost to add a concrete apron at the garage entrance while keeping an asphalt driveway in Ottawa?

A concrete apron at the garage entrance typically costs $800 to $2,500 in Ottawa, depending on size, thickness, and finish. This creates a durable transition zone that handles the heaviest vehicle loads while maintaining your existing asphalt driveway.

A concrete apron serves as a reinforced landing pad where vehicles enter and exit the garage — the area that experiences the most stress from turning, braking, and acceleration. Most aprons measure 3 to 4 metres wide by 2 to 3 metres deep, requiring 150mm thick concrete (minimum 30 MPa with air entrainment for Ottawa's freeze-thaw conditions) over a properly prepared granular base.

Material and labour breakdown for a typical 10 square metre apron includes excavation and base preparation ($200-400), 150mm of Granular A base ($150-250), concrete supply and placement ($400-800), finishing and curing ($200-400), plus disposal of excavated material ($100-200). Stamped or coloured concrete adds $300-800 to match architectural features, while exposed aggregate finish adds $200-500 and provides excellent traction for Ottawa's icy conditions.

The transition between concrete and asphalt requires careful attention to drainage and joint sealing. The concrete apron should be sloped at 2% minimum toward the driveway to prevent water pooling at the garage threshold. A control joint or expansion joint where concrete meets asphalt prevents cracking from differential movement during freeze-thaw cycles. Many contractors use a bead of polyurethane sealant in this joint to keep water out while allowing slight movement.

Timing considerations are critical in Ottawa — concrete work should be completed when nighttime temperatures stay above 5°C for at least 7 days to allow proper curing. Air-entrained concrete is essential for freeze-thaw durability, and the surface should not be exposed to deicing salts during the first winter to prevent scaling.

Permit requirements depend on the scope — if you're only replacing an existing apron in the same footprint, no permit is typically required. However, if you're expanding the apron or changing drainage patterns, check with the City of Ottawa. Any work within the municipal right-of-way (the area between your property line and the road) requires a separate permit and must meet city specifications.

Professional installation is strongly recommended for concrete aprons. Proper formwork, reinforcement placement, concrete finishing, and control joint cutting require specialized tools and experience. A poorly finished concrete apron develops surface scaling, cracking, and spalling within 2-3 Ottawa winters, requiring expensive replacement.
