What's the price range for interlock paver driveways in Ottawa compared to poured concrete?

Interlock pavers and poured concrete are both premium driveway options in Ottawa, and each has a distinct cost profile that homeowners should understand before committing.

Interlock Paver Driveway Costs

A full interlock paver driveway in Ottawa typically costs $18 to $35 per square foot installed, with the wide range reflecting material choice and pattern complexity:

• Standard concrete pavers (Holland, Roma style): $18 to $24 per square foot
• Premium pavers (Techo-Bloc, Unilock Thornbury, tumbled stone): $24 to $30 per square foot
• Natural stone pavers (granite, flagstone): $30 to $45 per square foot

For a standard 500 sq ft two-car driveway in Kanata or Barrhaven, expect to pay $9,000 to $17,500 for mid-range interlock. A 400 sq ft single-car driveway runs $7,200 to $14,000.

Pattern complexity affects labour costs. A simple running bond or stacked pattern is the most affordable. Herringbone adds about $2 to $3 per square foot in labour due to the angled cutting required. Circular or fan patterns with soldier course borders push labour costs even higher.

Poured Concrete Driveway Costs

Standard poured concrete in Ottawa costs $12 to $20 per square foot for a basic broom-finish installation. Upgraded finishes change the price significantly:

• Broom finish (basic): $12 to $16 per square foot
• Exposed aggregate: $16 to $22 per square foot
• Stamped concrete: $18 to $25 per square foot
• Coloured/stained concrete: $15 to $22 per square foot

That same 500 sq ft driveway in concrete runs $6,000 to $12,500 depending on finish.

Base Preparation Costs (Same for Both)

Both materials require the same granular base preparation, which is critical in Ottawa's climate. With frost penetrating 1.2 to 1.5 metres deep, the base must be at least 10 to 14 inches of compacted Granular A and B. On Leda clay soils — prevalent in Nepean, Gloucester, and south Ottawa — geotextile fabric and potentially extra excavation are needed. Base preparation runs $4 to $8 per square foot regardless of the surface material and is sometimes quoted separately.

Maintenance and Repair Cost Comparison

This is where interlock has a major advantage in Ottawa's freeze-thaw climate:

• Interlock repairs: Individual pavers that crack or heave can be lifted and reset for $3 to $6 per square foot for the affected area. Joint sand replacement costs $0.50 to $1.00 per square foot and should be done every 2 to 3 years.
• Concrete repairs: A cracked concrete slab cannot be easily fixed. Patching costs $500 to $1,500 per section and rarely matches the original appearance. Full section replacement requires saw-cutting and repaving at $15 to $25 per square foot.

After a harsh Ottawa winter with repeated freeze-thaw cycles and heavy salt use, interlock pavers flex without cracking. Concrete is rigid and more prone to surface spalling and structural cracking, especially in the first 5 years if the mix wasn't optimized for Ottawa conditions.

Which Is the Better Value?

Interlock costs 30 to 50% more upfront but offers dramatically lower long-term repair costs. Over a 25-year period, total ownership cost for both materials often converges to within 10 to 15% of each other when you factor in concrete crack repairs and potential section replacements.

For homeowners in Ottawa planning to stay in their home 10+ years, interlock typically delivers better long-term value. For those selling within 5 years, concrete offers a lower entry cost with comparable curb appeal.
