How Moisture Infiltration Worsens Unsealed Cracks
Unsealed cracks in pavements and parking lots may seem minor at first, but moisture infiltration can rapidly accelerate their deterioration. Understanding how water impacts these cracks is crucial for maintaining durable surfaces, especially in a city like Toronto where weather conditions vary significantly.

The Hidden Danger of Moisture in Cracks
When cracks in asphalt or concrete go unsealed, moisture penetrates beneath the surface. This intrusion doesn’t just sit idle; it causes a series of destructive processes that weaken the structural integrity of the pavement. In Toronto, the freeze-thaw cycle is especially brutal, making moisture infiltration a serious concern for property owners and managers.
How Moisture Negatively Affects Pavement
- Expansion and Contraction: Water trapped inside cracks freezes and expands, widening the crack.
- Material Erosion: Moisture erodes underlying layers, reducing support beneath the surface.
- Accelerated Aging: Persistent moisture leads to premature pavement aging and surface degradation.
- Weakening of Bond: Water reduces adhesion between aggregate and binder in asphalt.
- Increased Risk of Potholes: Cracks grow larger, eventually collapsing into potholes.
Why Sealing Cracks is Essential
Sealing cracks prevents moisture from infiltrating and protects the pavement from further damage. For businesses and municipalities in Toronto, entrusting this task to experts like Capital Parking Lot Line Painting ensures the job is done with quality materials and proper techniques.
