How Sealcoating Helps Protect Against Oil and Gas Spills
Sealcoating is an essential maintenance process that safeguards parking lots and asphalt surfaces from the damaging effects of oil and gas spills. In cities like Thunder Bay, where weather and traffic conditions can accelerate asphalt deterioration, sealcoating offers a reliable protective barrier.

What Is Sealcoating?
Sealcoating involves applying a protective liquid layer over asphalt surfaces, creating a shield that prevents harmful substances like oil, gasoline, and UV rays from penetrating and degrading the pavement. This treatment not only extends the life of the asphalt but also enhances its appearance, providing a fresh, black finish.
The Impact of Oil and Gas Spills on Asphalt
Oil and gas spills are common challenges for parking lots, especially in busy urban centers such as Thunder Bay. When these substances seep into asphalt, they break down the oils that bind the aggregate together, leading to soft spots, cracks, and potholes. Over time, untreated spills accelerate pavement deterioration, resulting in costly repairs and unsafe surfaces.
How Sealcoating Provides Protection
Sealcoating acts as a protective barrier that prevents oil and gas from soaking into the asphalt. By sealing the surface pores, it reduces the likelihood of chemical penetration and surface damage. Here’s how sealcoating helps:
- Prevents Penetration: Creates a water-resistant and chemical-resistant layer that blocks oil and gas.
- Extends Asphalt Lifespan: Slows down oxidation and deterioration caused by spills and weather.
- Improves Surface Appearance: Restores a uniform black finish that enhances curb appeal.
- Reduces Maintenance Needs: Minimizes the frequency of repairs due to surface damage.
