How Water and Salt Damage Asphalt Through Cracks

Asphalt is a durable and long-lasting material, but it's not invincible. Over time, cracks can form in the surface, allowing water and salt to seep in and cause damage. Capital Parking Lot Line Painting, a leading line marking company in Cambridge, Ontario, understands the importance of addressing these issues promptly.

Asphalt Crack

The Dangers of Water Infiltration

When water enters through cracks in the asphalt, it can cause several problems. First, it can lead to erosion, weakening the base and subbase layers of the pavement. This can result in potholes, depressions, and other structural issues that can be costly to repair.

Freeze-Thaw Cycles

In areas like Cambridge, where temperatures fluctuate above and below freezing, water infiltration can be even more damaging. As water freezes and expands, it can widen the cracks, allowing more water to enter and exacerbating the problem.

The Impact of Salt

During the winter months, salt is often used to melt ice and snow on parking lots and roads. While this practice can improve safety, it can also have detrimental effects on asphalt. When salt dissolves in water and enters through cracks, it can accelerate the deterioration of the asphalt binder, weakening the overall structure.

Preventing Damage

To protect your asphalt surface from water and salt damage, it's essential to address cracks as soon as they appear. Capital Parking Lot Line Painting offers crack sealing services to prevent water and salt infiltration, extending the life of your asphalt surface.

  • Crack sealing involves cleaning out the cracks and filling them with a rubberized sealant.
  • This creates a barrier that prevents water and salt from entering and causing further damage.
  • Regular maintenance and timely repairs can save you from costly repaving projects down the line.
