Why Asphalt Sealcoating Is Important

Asphalt parking lots and driveways are constantly exposed to weather, sunlight, and vehicle traffic. Over time these conditions cause the surface of the asphalt to dry out and begin to break down. Without protection, asphalt can develop cracks, surface deterioration, and eventually potholes.

Sealcoating provides a protective layer that helps shield the asphalt from moisture, ultraviolet rays, and oxidation. By sealing the surface, sealcoating slows the aging process of the asphalt and helps extend the life of the pavement.

In the Quad Cities region, freeze-thaw cycles during the winter months can accelerate asphalt deterioration. Water can enter small cracks in the pavement and expand when it freezes, gradually widening the cracks and weakening the surface. Sealcoating helps reduce the amount of water that penetrates the asphalt.

Regular sealcoating is one of the most effective ways to maintain asphalt surfaces and avoid costly repairs or premature replacement.

Signs Your Asphalt May Need Sealcoating

Over time, asphalt surfaces naturally begin to show signs of wear. One of the first indicators is fading of the asphalt color from deep black to a dull gray. This fading occurs as sunlight and oxidation break down the surface oils in the pavement.

Other signs that sealcoating may be needed include:

• small surface cracks forming in the asphalt

• rough or dry texture on the pavement

• water soaking into the asphalt instead of running off

• areas where the asphalt surface appears worn or brittle

Applying sealcoat at the right time helps protect the pavement before these small issues develop into larger cracks or potholes.

Our Sealcoating Process

At Behncke Construction, every sealcoating project begins with preparing the asphalt surface properly. The pavement must be thoroughly cleaned so that the sealcoat material bonds correctly with the asphalt.

If cracks are present in the pavement, they are typically sealed before the sealcoating application. This prevents water from entering the cracks and damaging the asphalt beneath the surface.

Once the surface is prepared, the sealcoat material is applied evenly across the pavement to create a protective layer. The coating helps restore the appearance of the asphalt while protecting it from weather and traffic.

Proper preparation and application are essential for sealcoating to perform effectively and last for several years.

Residential and Commercial Sealcoating

Behncke Construction provides sealcoating services for both residential and commercial properties throughout the Quad Cities area.

Residential projects often include asphalt driveways and private parking areas where homeowners want to protect the pavement and maintain a clean appearance.

Commercial properties frequently require sealcoating for parking lots, access lanes, and other paved areas that experience heavier traffic. Maintaining these surfaces helps extend the life of the pavement and improves the overall appearance of the property.

Because our company performs both asphalt and concrete repair work, we are able to evaluate the condition of the pavement and recommend the best maintenance approach.
