Why it is Important to Seal Asphalt

Man,Sealing,Asphalt,DrivewayAsphalt is a durable and versatile material commonly used for roadways, driveways, parking lots, and other paved surfaces. However, over time, asphalt can deteriorate due to factors such as weather, heavy traffic, and exposure to chemicals. To protect and prolong the lifespan of asphalt surfaces, it is essential to seal them regularly. In this blog post, we will discuss the importance of asphalt sealing and the benefits associated with this preventive maintenance practice.

1. Protection against Weathering:

One of the primary reasons for sealing asphalt is to protect it from the damaging effects of weathering. Constant exposure to elements like sunlight, rain, snow, and freeze-thaw cycles can cause the asphalt to fade, crack, and deteriorate. By applying a sealant, a protective layer is created, shielding the asphalt from UV rays, moisture, and temperature fluctuations, thus preventing premature degradation.

2. Preventing Water Damage:

Water is one of the biggest enemies of asphalt. When water seeps into cracks and crevices in the asphalt surface, it can cause significant damage. As water expands and contracts during freezing and thawing cycles, it can widen existing cracks, leading to potholes and other structural issues. Sealing the asphalt creates a waterproof barrier, preventing water from infiltrating the surface and causing damage from within.

3. Minimizing Cracking and Potholes:

Cracks in the asphalt surface not only diminish its appearance but also compromise its structural integrity. Over time, these cracks can widen and deepen, leading to the formation of potholes. By sealing the asphalt, cracks are filled and sealed, preventing further expansion and minimizing the formation of potholes. Regular maintenance and sealing can significantly prolong the life of the asphalt surface and save money on costly repairs.

4. Enhancing Appearance:

Sealing asphalt not only protects it from damage but also enhances its appearance. Over time, asphalt can fade and become dull due to oxidation and wear. Applying a sealant can rejuvenate the appearance of the surface, giving it a fresh, black appearance that enhances the curb appeal of properties. This is particularly important for driveways and commercial parking lots, creating a positive first impression for visitors and customers.

5. Easy Maintenance:

Sealed asphalt surfaces are easier to maintain than unsealed ones. The sealant creates a smooth and even surface, making it easier to remove dirt, debris, and stains. Additionally, the sealed surface is more resistant to the penetration of oil, gasoline, and other chemicals that can stain and degrade unsealed asphalt. Cleaning and maintaining a sealed asphalt surface is more cost-effective and less time-consuming than dealing with extensive repairs.

6. Cost-effective:

While sealing asphalt requires an upfront investment, it is a cost-effective long-term solution. Regularly sealing asphalt surfaces can significantly extend their lifespan, avoiding the need for expensive repairs or complete resurfacing. The cost of sealant and application is relatively low compared to the potential costs of extensive damage and reconstruction. Investing in sealing can save money over time and contribute to long-term sustainability.

7. Safety Improvement:

Sealed asphalt surfaces improve safety for both pedestrians and vehicles. By filling cracks and smoothing the surface, trip hazards are minimized, reducing the risk of accidents and injuries. Additionally, the dark surface created by the sealant enhances visibility during nighttime, improving driver safety. Maintaining well-sealed asphalt surfaces is an important part of creating a safe environment for everyone.


Sealing asphalt is vitally important to protect the surface from weathering, water damage, cracking, and potholes. It not only enhances the appearance of the asphalt but also makes it easier to maintain and extends its lifespan. The cost-effectiveness and safety benefits associated with sealing make it an essential preventive maintenance practice for any property owner or manager. By investing in regular sealing, you can preserve the integrity and attractiveness of your asphalt surfaces for years to come.
