Protecting Killeen's driveways and parking lots from the harsh Texas sun and heavy traffic with expert asphalt sealcoating.

This application is not a structural repair but a surface treatment designed to fill minor surface voids, restore the pavement's dark color, and create a barrier against environmental damage. It includes meticulous surface preparation, crack filling for hairline cracks, and the precise application of one or two coats of high-quality sealer.
Our approach begins with a comprehensive assessment of your pavement's condition to determine the appropriate sealer type and application method. We prioritize proper surface adhesion, which means we use commercial-grade power blowers and sweepers to remove all loose debris, dirt, and oil spots. Any oil or grease stains are pre-treated with a primer to ensure the sealer bonds correctly, preventing premature peeling or flaking.
For Killeen properties, sealcoating is particularly vital because the intense Texas sun and fluctuating temperatures accelerate asphalt oxidation and degradation. UV radiation breaks down the asphalt binder, causing the surface to become brittle, faded, and prone to cracking. Sealcoating replenishes the asphalt's oils, restoring its flexibility and dark appearance, which helps it absorb more heat and melt ice faster in winter, and protects against the summer heat.
Many property owners ask about the best time to sealcoat. Generally, asphalt should be sealed 6-12 months after initial paving to allow for proper curing, and then every 2-4 years depending on traffic volume and weather exposure. We use commercial-grade sealers formulated for durability and resistance to common automotive fluids, ensuring a robust protective layer that withstands daily wear and tear. After application, we recommend keeping traffic off the sealed surface for at least 24-48 hours, depending on ambient temperatures and humidity.
Asphalt sealcoating is crucial for Killeen properties primarily due to the local climate's impact on pavement integrity. The intense summer heat and strong UV radiation in Central Texas rapidly oxidize asphalt, causing it to lose its flexibility and turn gray. This oxidation leads to surface cracking and raveling, which means the pavement becomes more susceptible to water penetration and structural damage.
Our regional soil conditions, particularly the expansive clay soils common around Killeen, also play a role. While sealcoating doesn't address sub-base issues, it prevents surface water from infiltrating cracks and reaching the sub-base, which could exacerbate soil movement and lead to further pavement distress. By creating a waterproof barrier, sealcoating helps maintain the structural stability of the asphalt layer above the soil.
Furthermore, Killeen experiences periods of heavy rainfall and occasional freezing temperatures. An unsealed surface allows water to seep into small cracks, and when this water freezes and expands, it creates larger cracks and potholes. Sealcoating seals these hairline cracks and prevents water intrusion, significantly reducing the need for costly asphalt patching and extending the overall service life of your driveway or parking lot.
We begin by thoroughly cleaning the entire asphalt surface using commercial-grade power blowers, stiff brooms, and wire brushes to remove all dirt, debris, loose aggregate, and organic matter. Any oil or gas stains are pre-treated with a specialized primer to ensure optimal sealer adhesion.
Existing cracks up to 1/2 inch wide are filled with a hot-applied rubberized crack filler, which expands and contracts with the pavement to prevent water penetration. We also define clean edges, often using tape or careful brushwork, to protect adjacent concrete or landscaping.
Depending on the pavement's condition and traffic load, we apply one or two coats of a commercial-grade asphalt emulsion or refined coal tar sealer. This is typically done using spray applicators for even coverage on large areas, or squeegees and brushes for smaller, intricate sections.
After application, the sealed area is barricaded or marked with caution tape to prevent premature traffic. The sealer requires 24-48 hours to cure completely, depending on temperature and humidity, before it can withstand vehicle weight and foot traffic without damage.
