Water is one of the most destructive elements when it comes to asphalt pavement. Whether from rain, snow, or irrigation runoff, excess moisture seeps into the surface, leading to cracks, potholes, and overall degradation. sealcoating is an essential protective measure that prevents water from penetrating the asphalt, reducing long-term damage and costly repairs.
The Impact of Water on Asphalt
When water infiltrates asphalt, it weakens the underlying base, making the surface more susceptible to cracking and shifting. In colder climates, freeze-thaw cycles cause water to expand and contract within cracks, leading to even more severe damage. Over time, small cracks widen, resulting in potholes and structural instability.
Sealcoating acts as a waterproof barrier, preventing moisture from penetrating the pavement. It seals minor cracks and provides a smooth, protective layer that keeps water from reaching the asphalt’s foundation.
How Sealcoating Improves Water Resistance
A properly applied sealcoat creates a uniform surface that repels water, keeping it on top of the pavement rather than allowing it to seep into vulnerable areas. This significantly slows down the aging process and prevents costly repairs due to water-related damage. Additionally, sealcoating fills minor surface imperfections, reducing areas where water can collect and erode the pavement.
Conclusion
Water damage is one of the leading causes of asphalt deterioration, but sealcoating provides an effective solution to prevent moisture infiltration. By applying a sealcoat regularly, property owners can extend the lifespan of their pavement and avoid expensive repairs caused by water damage.
