- How long does a concrete driveway last in Ontario?
- A properly installed concrete driveway lasts 25-30+ years in Ontario. Key factors: 4-6 inch thickness, proper gravel base, air-entrainment for freeze-thaw resistance, control joints every 8-10 feet, and annual sealing. Avoid deicing salt in the first winter.
- When is the best time to pour concrete in Ontario?
- The ideal temperature for pouring concrete is 10-25°C, making May through October the best window in Ontario. Avoid pouring below 5°C — concrete won't cure properly. September-October often offers the best combination of weather and contractor availability.
- Should I choose concrete, asphalt, or interlock for my driveway?
- Concrete ($7,000-$12,000) lasts 25-30 years with minimal maintenance. Asphalt ($3,000-$7,000) lasts 15-20 years but needs resealing every 3-5 years. Interlock ($10,000-$20,000) is the most attractive but can shift in Ontario's freeze-thaw cycles.
