How Moisture Infiltration Worsens Unsealed Cracks

Cracks in pavement or concrete might seem minor at first, but when left unsealed, moisture infiltration can accelerate their deterioration, leading to costly repairs. Understanding how moisture impacts these cracks is essential for maintaining durable surfaces, especially in cities like Guelph where weather conditions can be unpredictable.

The Hidden Danger of Moisture in Unsealed Cracks

Cracks in concrete or asphalt allow water to seep beneath the surface. This moisture can freeze, thaw, and expand in colder months, further widening the cracks and destabilizing the base layers. Without timely intervention, these damages compound, affecting the overall integrity of parking lots, sidewalks, and roadways.

Why Unsealed Cracks Are Vulnerable

When cracks are left unsealed, they essentially act as channels for water and other elements like dirt and debris. This infiltration causes several problems:

  • Freeze-Thaw Cycles: Water freezes and expands, pushing cracks wider.
  • Base Layer Erosion: Moisture weakens the sub-base, causing settlement and uneven surfaces.
  • Vegetation Growth: Seeds can take root inside cracks, worsening structural damage.

Impact of Guelph’s Climate on Pavement Health

Guelph, ranked as one of the top 30 cities in Ontario, experiences diverse weather conditions, including cold winters and wet springs that exacerbate moisture infiltration issues. Seasonal freeze-thaw cycles make crack sealing an essential part of pavement maintenance in this region.

Ignoring these local climate factors can lead to premature pavement failure, increasing the need for costly repairs and disrupting property usability.
