Interlock vs Asphalt vs Concrete Driveway in Ottawa
By Aelia Construction and Design. Last updated .
Asphalt is generally the lowest-cost option but limited in look and needs sealing every three to five years. Concrete is very durable and can be stamped or stained. Interlock offers the most design choice and is repaired stone by stone, but depends on a well-built base. HomeStars lists a standard Ottawa driveway at about $4,000 to $8,000.
The short answer
There is no best material for every driveway. Asphalt usually costs the least. Concrete is durable and customizable. Interlock gives you the most choice of colour and pattern, and individual stones can be lifted and re-laid. In Ottawa, the quality of the base and the drainage matter as much as the material, because freeze and thaw cycles move poorly prepared ground.
| Interlock | Asphalt | Concrete | |
|---|---|---|---|
| Look | Many colours, shapes and patterns | Dark, uniform surface; limited customization | Plain, stamped or stained |
| Upkeep | Re-level or replace individual stones; refill joint sand | Sealing every three to five years, per HomeStars | Can crack in severe weather; repair and resurface |
| Relative cost | Paver patios are listed at about $15 to $25 per sq ft, above concrete patios at $10 to $15 | Generally less expensive than concrete, per HomeStars | Driveways listed at about $2,500 to $7,000 |
| Best when | You want a custom look and easy local repairs | You want the lowest upfront cost | You want a durable, clean surface |
What HomeStars publishes for Ottawa
These figures come from HomeStars’ Ottawa paving and concrete cost guides, updated in August 2026. They are published ranges for context and are not Aelia quotes. HomeStars’ paving average of about $4,443 comes from 120 homeowner reviews as of March 2022 and covers all paving types, so it is not a price for any one material.
- Standard-sized driveway installation: about $4,000 to $8,000
- Concrete driveway construction: about $2,500 to $7,000, depending on size and materials
- Concrete patios: about $10 to $15 per square foot
- Paver patios: about $15 to $25 per square foot
- Concrete contractors: about $80 to $130 per hour
The patio rates are the closest published guide to paver prices. A paver driveway has a larger area and a heavier base, so ask for a written quote.
Asphalt
HomeStars describes asphalt as less expensive than concrete, though it cannot be customized much. It needs sealing every three to five years. Asphalt repairs are seamless, which helps its long-term life.
Concrete
HomeStars calls concrete driveways extremely durable and notes they can be customized with stamps and stains. Even concrete can crack under severe weather and prolonged use, and repair and resurfacing are available. Some homeowners add a rubberized coating to reduce damage.
Interlock
Interlocking stone offers a natural look and a wide range of colours and patterns. Because the surface is made of individual units, a settled or stained section can be lifted and re-laid without replacing the whole driveway. The trade-off is that the result depends on the base: poor excavation or compaction shows up as dips and gaps. See our guide on what to know before you build an interlock driveway.
Ottawa conditions to plan for
- Freeze and thaw cycles that lift and drop poorly prepared ground
- Drainage that sends rain and melting snow away from the house
- Snow clearing, which scrapes asphalt and can catch the edges of stones
- Rules from the City of Ottawa if you widen or move a driveway. Check with the City before you start.
How to choose
- Choose asphalt if the upfront price matters most and you accept regular sealing.
- Choose concrete if you want a durable, clean surface and are happy with a simple finish or a stamped pattern.
- Choose interlock if you want a custom look and easy local repairs, and you will pay for a proper base.
- Whatever you choose, get written quotes for the same area from at least three contractors.

Frequently asked questions
Which is cheapest, interlock, asphalt or concrete?
HomeStars describes asphalt as less expensive than concrete. Paver surfaces are listed at higher per-square-foot rates than concrete, though a written quote for your area is the only reliable comparison.
How much does a driveway cost in Ottawa?
HomeStars lists a standard-sized driveway at about $4,000 to $8,000, and concrete driveways at about $2,500 to $7,000.
Which lasts longest in an Ottawa winter?
Each can last when installed over a well-prepared base with good drainage. Asphalt needs sealing, concrete can crack in severe weather, and interlock depends on the base under the stones.
Can interlock stones be repaired?
Yes. A settled or stained area can be lifted and re-laid, which is one advantage of individual stones.
