Understanding Freeze-Thaw Cycles and Their Impact

Freeze-thaw cycles occur when water seeps into cracks or pores in the asphalt, freezes, and expands, causing the pavement to crack and deteriorate. This repetitive process is especially common in Markham, a top 30 city in Ontario, where winter temperatures frequently dip below freezing and then rise again.

How Freeze-Thaw Cycles Damage Asphalt

• Water infiltration leads to internal pressure as it freezes and expands.
• Repeated expansion and contraction cause cracks to widen and deepen.
• Surface degradation allows more water infiltration, accelerating damage.
• Traffic stress worsens deteriorated areas, leading to potholes and crumbling.

The Role of Sealcoating in Post-Winter Maintenance

Sealcoating is the application of a protective layer on asphalt surfaces that helps seal cracks, prevent water infiltration, and shield the pavement from harmful UV rays. After enduring the harsh freeze-thaw cycles of winter, sealcoating acts as a barrier to protect your parking lot from further damage.

Why Sealcoating Is Crucial After Winter

• Water Resistance: Sealcoating prevents water from penetrating the asphalt, reducing freeze-thaw damage.
• UV Protection: It protects the surface from sun damage, which can dry out and weaken asphalt.
• Improved Appearance: Sealcoating restores the black finish, making parking lots look fresh and well-maintained.
• Extended Pavement Life: It slows down oxidation and prevents cracking, extending the asphalt’s lifespan.

Common Sealcoating Mistakes to Avoid

To ensure your sealcoating lasts and provides the protection you need, avoid these common mistakes:

• Applying sealcoat over wet or icy surfaces, which reduces adhesion.
• Not repairing cracks and potholes before sealcoating.
• Choosing low-quality sealcoating materials to cut corners.
• Ignoring timing – sealcoating too early in the season can be ineffective.
• Failing to maintain the sealcoated surface with regular inspections.

Step-by-Step Guide to Sealcoating Your Parking Lot

Understanding the sealcoating process can help you better prepare your parking lot for this important maintenance task:

• Inspection: Assess the pavement condition and identify necessary repairs.
• Cleaning: Remove debris, dirt, and loose material to ensure proper adhesion.
• Repair: Fill cracks and potholes to create a smooth surface.
• Sealcoat Application: Evenly apply the sealcoating material using specialized equipment.
• Drying: Allow adequate time for the sealcoat to cure before traffic is allowed.
• Line Painting: Once the sealcoat has dried, refresh or apply new line painting for clear markings.
