What Affects Your Interlock Cost?
Understanding the factors that influence pricing
Site Conditions
Slope, drainage issues, tree roots, and accessibility affect excavation time and materials needed.
Can add 10-25% to base costMaterial Selection
Premium pavers (Unilock, Techo-Bloc) cost more than standard options but offer better durability and aesthetics.
Standard vs premium: $3-8/sq ft differenceDesign Complexity
Intricate patterns (herringbone, circular), multiple paver types, and curves require more labor.
Can add 15-30% to installation costBase Depth Requirements
Ottawa's freeze-thaw cycles require 10-12" base for driveways. Patios may need 6-8".
Proper base prevents costly repairs laterRemoval & Disposal
Removing existing concrete, asphalt, or old pavers adds to project cost.
Concrete removal: $3-5/sq ft extraAdd-Ons & Features
Lighting, seating walls, steps, borders, and drainage solutions add value and cost.
Steps: $150-300 each. Lighting: $200-500Is Interlock Worth the Investment?
Interlock paving costs more upfront than asphalt or poured concrete, but delivers superior long-term value for Ottawa homeowners. Here's why:
- Handles freeze-thaw cycles: Flexible joints prevent the cracking that destroys rigid surfaces in Ottawa winters.
- Easy repairs: Individual pavers can be replaced if damaged - no need to redo the entire surface.
- 20-25 year lifespan: Quality interlock outlasts asphalt (8-12 years) and concrete (15-20 years) when properly installed.
- Increases property value: Curb appeal matters. Interlock driveways and patios boost resale value.
- Low maintenance: No resealing every 2-3 years like asphalt. Occasional polymeric sand top-up is all you need.

Interlock Pricing FAQs
Common questions about interlock costs in Ottawa
How much does an interlock driveway cost in Ottawa?
Interlock driveways in Ottawa typically cost between $20-30 per square foot installed. For a standard two-car driveway (400-600 sq ft), expect to pay $8,000-$18,000. This includes excavation, gravel base, pavers, and polymeric sand. Premium pavers and complex designs can increase costs.
Why is interlock more expensive than asphalt or concrete?
While interlock has a higher upfront cost, it offers significant long-term value. Unlike asphalt that cracks and needs resealing every 2-3 years, or concrete that can crack beyond repair, interlock pavers can be individually replaced if damaged. Interlock also handles Ottawa's freeze-thaw cycles better due to its flexible joint system.
What affects the price of an interlock project?
Several factors affect interlock pricing: site conditions (slope, drainage, accessibility), material quality (standard vs premium pavers), design complexity (patterns, curves), base requirements for Ottawa's climate, removal of existing surfaces, and add-ons like steps, lighting, or seating walls.

Is it cheaper to repair or replace interlock?
It depends on the extent of damage. Small repairs ($500-$2,000) are cost-effective for isolated issues. If more than 30-40% of your interlock shows problems like widespread settling, extensive weed growth, or multiple sunken areas, full replacement may be more economical long-term.
