How Moisture Infiltration Worsens Unsealed Cracks

How Moisture Infiltration Worsens Unsealed Cracks

Cracks in pavement and concrete surfaces are inevitable, but leaving them unsealed can accelerate damage, especially when moisture infiltration comes into play. Understanding how water worsens these cracks is essential for maintaining the longevity of your surfaces, particularly in climates like Ajax, Ontario.

Why Unsealed Cracks are Problematic

Cracks might start small and appear harmless, but when left unsealed, they open the door for moisture to penetrate deep into the pavement or concrete. This not only reduces the structural integrity but also increases maintenance needs over time. In a city like Ajax, which experiences seasonal fluctuations, the effects of moisture are particularly damaging.

The Role of Moisture in Crack Deterioration

Moisture infiltrates through unsealed cracks and interacts with the base and sub-base materials beneath the surface. When temperatures drop, this trapped water freezes and expands, causing the cracks to widen and deepen—a process known as freeze-thaw cycling. Over time, this cycle causes severe surface degradation and can even lead to potholes or structural failures.

Common Issues Caused by Moisture Infiltration

  • Freeze-Thaw Damage: Expansion of frozen water leads to crack enlargement.
  • Base Erosion: Moisture weakens the foundation supporting the pavement.
  • Surface Spalling: Chipping and flaking of the concrete or asphalt surface.
  • Increased Repair Frequency: Unsealed cracks propagate faster, necessitating more frequent repairs.
