How Moisture Infiltration Worsens Unsealed Cracks

Cracks in pavement and concrete surfaces are more than just an eyesore; they are gateways for moisture infiltration that can accelerate deterioration. Understanding how moisture worsens unsealed cracks is essential for property owners in St. Catharines who want to maintain the longevity and safety of their parking lots and walkways.

Cracked pavement with moisture infiltration

Why Cracks Appear and Why They Matter

Cracks commonly form in asphalt and concrete due to weathering, heavy traffic, freeze-thaw cycles, and natural settling of the ground. While small cracks may seem harmless initially, they can quickly expand and lead to more severe structural damage if left unsealed. This is particularly important in St. Catharines, where seasonal changes bring varying moisture levels that exacerbate the problem.

The Role of Moisture in Crack Deterioration

Moisture infiltration is the primary culprit in the accelerated breakdown of unsealed cracks. When water enters these gaps, several damaging processes begin:

  • Freeze-Thaw Cycles: Water trapped in cracks freezes during cold weather, expanding and forcing cracks to widen.
  • Soil Erosion: Moisture can wash away the base material under pavement, causing uneven surfaces and more cracking.
  • Material Weakening: Continuous wetting and drying weaken the asphalt or concrete, reducing its lifespan.

Common Mistakes That Increase Moisture Damage

Many property managers make mistakes that unknowingly make moisture damage worse. Avoid these pitfalls to extend the life of your pavement:

  • Ignoring small cracks until they become large and costly to repair
  • Applying line painting without sealing cracks first
  • Using improper sealants that do not adhere well or resist moisture
  • Failing to schedule regular maintenance checks, especially in regions like St. Catharines where weather varies
