How Moisture Infiltration Worsens Unsealed Cracks
Unsealed cracks in pavement and concrete surfaces may seem harmless at first, but when moisture infiltrates these vulnerable areas, the damage can escalate rapidly. Understanding how moisture affects unsealed cracks is essential for property owners, especially in regions like Vaughan, where seasonal weather fluctuations are common.

The Hidden Dangers of Unsealed Cracks
Cracks in parking lots, driveways, and sidewalks are inevitable over time due to natural wear and environmental stresses. However, when these cracks remain unsealed, they become pathways for moisture, which can seep deep beneath the surface. This infiltration initiates a chain reaction that compromises the structural integrity of the pavement.
How Moisture Penetrates Cracks
Water enters cracks primarily through surface runoff, rain, melting snow, or even irrigation systems. Once inside, moisture can stay trapped beneath the pavement, especially if drainage is poor. This trapped moisture is difficult to evaporate, leading to further deterioration.
Consequences of Moisture Infiltration
- Freeze-Thaw Cycles: In Vaughan, winters can be harsh. Water trapped inside cracks freezes and expands, widening the cracks and causing additional surface damage.
- Subsurface Erosion: Moisture can erode the base layers beneath the pavement, reducing support and causing settling or sinkholes.
- Accelerated Aging: Continuous moisture exposure accelerates the breakdown of asphalt and concrete binder materials, leading to brittleness and crumbling.
