What is the average cost of interlock driveway in New Brunswick in 2026?

Interlock driveways in New Brunswick typically cost between $15-35 per square foot installed, making a standard 600 sq ft driveway run $9,000-21,000 depending on materials and site conditions.

The wide price range reflects several key factors. Basic concrete pavers start around $15-20/sq ft, while premium natural stone or specialty patterns can reach $30-35/sq ft. A typical two-car driveway (20' x 30') falls into the $12,000-18,000 range for mid-grade materials and standard installation.

Site preparation significantly impacts costs — New Brunswick's clay soils and freeze-thaw cycles demand proper excavation (typically 18-24" deep) and a robust base of compacted granular material. Properties with poor drainage, steep slopes, or challenging access can add $3,000-8,000 to the project. The 4+ foot frost line depth across the province means proper base preparation isn't optional — skimping here leads to heaving and cracking within a few winters.

Material choices affect both upfront and long-term costs. Concrete pavers ($8-15/sq ft for materials) offer good value and consistent quality, while natural stone ($20-40/sq ft) provides premium aesthetics but requires more skilled installation. Permeable pavers, increasingly popular for environmental compliance, typically add 15-20% to material costs but may reduce stormwater management requirements.

Labour represents 40-60% of total project cost in New Brunswick's market. Experienced crews who understand proper base construction, edge restraints, and jointing sand techniques are essential — poor installation voids most manufacturer warranties. Spring and fall are peak seasons, so booking early or scheduling winter planning can sometimes secure better rates.

Most contractors include excavation, base preparation, paver installation, and initial sand sweeping. Excluded items typically include permits (if required by your municipality), utility marking, decorative lighting, and ongoing maintenance supplies. Always verify what's covered in your quote.

Practical next step: Measure your driveway area and get quotes from at least three contractors in our New Brunswick directory. Ask to see recent local projects and verify they understand NB's soil conditions and climate requirements — proper installation here prevents costly repairs down the road.
