Challenge Asphalt Commercial Seal Coating

Keeping up with your parking lot or roadway’s heavy usage requires a comprehensive maintenance plan. Regular seal coating is one of the best ways to prevent damage and maintain asphalt’s appearance. At Challenge Asphalt, we have spent decades perfecting our commercial seal coating for projects of all scopes.

Benefits of Seal Coating

+ Short and long-term cost efficiency by extending asphalt lifespan

+ Prevention of issues, such as water infiltration, that cause potholes and sinkholes

+ Routed cracks stay sealed three to four times longer than cracks that aren’t routed

+ Increased property value and appeal

+ Improved pavement cleaning

What to expect

When you choose Challenge Asphalt for your seal coating needs, you get our best-in-class equipment, decades of experience, and commitment to your project. For new asphalt, we recommend applying a GuardTop seal coat within the first year of installation. If the parking lot is older, we may first need to patch and repair cracks and potholes. In both cases, we broom on to remove excess aggregate particles.

Because seal coating is a preventative measure, we recommend reapplying it every two to three years. Given the heavy traffic parking lots sustain, our crew will outline a comprehensive maintenance plan that includes other services like overlays to increase your asphalt’s lifecycle.

About GuardTop Seal Coat

Our seal coat material of choice is GuardTop, an asphalt-based product that includes a proprietary blend of base stocks and mineral aggregates for ultimate durability. Because GuardTop is not tar-based, it’s an eco-friendly option to protect your commercial lot or roadway.
