4 Benefits Of Asphalt Sealcoating

Asphalt sealcoating is a great way to make your driveway or parking lot look good. A sealant is applied to the surface of the asphalt and then allowed to dry, forming a durable and protective layer of asphalt. This process has many benefits that go beyond aesthetics.

Read on to discover four benefits of asphalt sealcoating.

1. Improves Asphalt Paving Durability

The most common benefit of asphalt sealcoating is that it helps to improve the durability and life of the pavement surface. Asphalt is an excellent surface for driving on, but water, traffic, and other factors can compromise its wear resistance. Sealcoating can help restore this wear resistance.

Sealcoating provides a smooth surface that allows water to drain away from the surface rather than pooling at its base. This helps prevent potholes and other damage to your driveway or parking lot, improving their lifespan.

2. Prevents Water Intrusion Beneath the Surface

Sealcoating can prevent surface water from seeping underneath the pavement. Water seepage can lead to severe damage over time. When water seeps into asphalt, it creates puddles and cracks, leading to costly repairs.

Sealcoating also protects against rainwater, which can erode asphalt surfaces if they aren't protected. In addition, rainwater may react with oil leakages from your car's engine components. This can cause damage that may be expensive to repair. 

3. Slows Deterioration From Oxidation

A sealant helps slow down the process of oxidation, which can cause cracking and other damage to your asphalt driveway or parking lot. Oxidation occurs when the sun's UV radiation penetrates through the top layer of asphalt and reaches the underlying base material.

Sealants help prevent this by creating a barrier between the sunlight and the asphalt's underlying layers. This prevents oxygen from entering your asphalt, which prevents it from deteriorating quickly.

4. Protects the Asphalt Binder From Oils and Gasoline

Asphalt is notorious for absorbing oil from cars passing over it every day. Still, it also absorbs gasoline vapors from passing vehicles and other harmful contaminants like exhaust fumes. The best part about asphalt sealcoating is that it protects the asphalt binder from oils, gasoline, and other harmful elements. 


If you have experienced cracks in your driveway or parking lot, this would be an excellent time to consider sealcoating. Asphalt sealcoating will help stabilize the pavement surface and prevent further cracking or damage. Therefore, contact an asphalt paving contractor if you need asphalt sealcoating services to get quality services.
