Asphalt driveways in Alberta face some of the toughest weather conditions around. From heavy snowfall and frigid winter temperatures to intense summer sun, our driveways endure it all. Without proper maintenance, these seasonal challenges can cause asphalt to crack, crumble, and deteriorate much faster than expected. Here’s a guide on how to weatherproof your driveway, so it can withstand Alberta’s four distinct seasons and stay looking great year-round.
1. Spring: Repair Winter Damage
Spring thaw often reveals new cracks and potholes that developed over the winter due to the freeze-thaw cycle. Here’s what to do to repair winter damage:
Inspect for Damage: Walk your driveway and inspect it closely. Look for any cracks, divots, or potholes.
Fill Cracks: Use a high-quality asphalt crack filler to fill in any small cracks. This prevents water from seeping into them, which can expand and worsen the damage when temperatures fluctuate.
Repair Potholes: For larger potholes, use a cold-patch asphalt mix. Compact the material well to ensure a strong bond, and level it with the surrounding surface. By addressing these issues promptly in spring, you’ll avoid them worsening over the summer.
2. Summer: Sealcoat and Protect Against UV Rays
Alberta summers can bring intense sun and high temperatures, which can soften asphalt and cause fading, cracking, and oxidation. Sealcoating adds a protective layer that shields your driveway from UV rays and extends its life.
Choose the Right Sealant: Use a professional-grade sealant designed to handle the unique conditions of Canadian weather. This layer protects the asphalt from sun exposure and heavy vehicle traffic.
Wait for Optimal Conditions: Ensure the temperature is consistently above 15°C with no rain in the forecast for at least 24 hours after application.
Seal Every 2-3 Years: Reapply sealant every two to three years to maintain a protective barrier. Consistent sealing is essential for long-term durability.
3. Fall: Prepare for Winter with Preventative Maintenance
Fall is your last chance to prepare your driveway for Alberta’s harsh winter. This season, focus on clearing debris, applying a final layer of protection, and ensuring the driveway is free from potential drainage issues.
Clean Thoroughly: Sweep away any debris, including leaves, dirt, and rocks, as these can retain moisture and accelerate damage.
Inspect Drainage: Make sure water can drain off your driveway rather than pooling in low spots. Standing water can seep into cracks and freeze, leading to serious winter damage.
Final Crack Check: Any cracks that have opened up since spring should be filled now to prevent winter freeze-thaw cycles from making them worse.
4. Winter: Snow Removal and Ice Control
Winter weather is the most challenging time for asphalt. While you can’t prevent snow and ice, you can protect your driveway with careful snow removal and ice management.
Use Plastic Shovels or Snow Blowers: Avoid metal shovels or blades, which can scrape and damage the asphalt. A plastic shovel is gentle enough to clear snow without scratching or chipping.
De-Ice Carefully: Salt and other chemical de-icers can damage asphalt over time. Consider using sand or a salt-free, asphalt-safe de-icing product. Applying a small amount of de-icer in high-traffic areas can help keep the surface manageable, but don’t overdo it.
Additional Tips for Year-Round Maintenance
Address Stains Promptly: Oil, gasoline, and other car fluids can eat away at asphalt. Clean these spills as soon as possible to prevent deterioration.
Regular Sweeping: Keep your driveway clear of rocks, dirt, and debris year-round. This prevents material from getting embedded in the asphalt, which can cause abrasion over time.
Avoid Heavy Loads: Avoid parking heavy equipment on your driveway for extended periods, as this can create dents and cracks that may worsen in extreme temperatures.
With a little time and effort, you can weatherproof your asphalt driveway to withstand Alberta’s ever-changing climate. Regular maintenance throughout the seasons can help you prevent small issues from turning into major, costly repairs. A weatherproofed driveway isn’t just more functional; it also boosts curb appeal and extends the life of your asphalt, making it a worthwhile investment.
