Protecting and rejuvenating Flagstaff's asphalt surfaces with durable slurry coating solutions designed for our unique climate.

This application is a cost-effective preventative maintenance treatment that seals small cracks and voids, improves skid resistance, and provides a new wearing surface. It's distinct from sealcoating because it incorporates aggregate, offering a thicker, more durable layer that can fill minor surface imperfections up to 3/8 inch.
Our approach to slurry coating begins with a thorough inspection of your pavement to confirm suitability. We then prepare the surface by cleaning it of all debris, oil, and loose material, and addressing any larger cracks or potholes that exceed the slurry's filling capacity. The slurry mixture is precisely proportioned and mixed on-site, then applied uniformly using specialized equipment, ensuring consistent coverage and texture across the entire area. This careful preparation and application are critical for the coating's adhesion and long-term performance.
For properties in Flagstaff, slurry coating is particularly beneficial because our high-altitude climate, with its intense UV exposure and freeze-thaw cycles, can accelerate asphalt deterioration. The slurry provides a sacrificial layer that absorbs this environmental stress, preventing water intrusion and oxidation from reaching the base asphalt. This proactive protection is essential for preserving the structural integrity and aesthetic appeal of driveways and parking lots, especially given Flagstaff's significant temperature fluctuations between seasons.
Property owners often ask about the curing time and traffic readiness. While the surface may appear dry quickly, full curing depends on temperature, humidity, and sunlight. Typically, light foot traffic can resume within a few hours, but we recommend waiting 24-48 hours before allowing vehicle traffic. This allows the emulsion to properly break and the aggregate to bind, preventing tracking and ensuring the coating achieves its maximum durability.
Slurry coating is a strategic investment for Flagstaff properties because it directly addresses the specific challenges posed by our local environment. The intense UV radiation at 7,000 feet elevation causes asphalt binders to oxidize and become brittle, leading to surface cracking. Slurry coating provides a fresh, UV-resistant layer that shields the underlying pavement, significantly slowing this degradation process.
Furthermore, Flagstaff's freeze-thaw cycles are particularly damaging. Water penetrates small cracks, freezes, expands, and then thaws, widening those cracks into potholes. The aggregate-rich slurry seals these hairline cracks and minor surface voids, creating a more impermeable barrier against water infiltration. This prevents the destructive expansion and contraction that shortens pavement life.
By applying slurry coating every 5-7 years, property owners can effectively double the lifespan of their asphalt pavement compared to doing no maintenance. This preventative measure postpones the need for costly full-depth repairs or complete repaving, saving considerable expense over time. It also maintains a clean, uniform appearance, which contributes to property value and curb appeal in Flagstaff's diverse neighborhoods.
We conduct a detailed inspection of your asphalt to identify existing damage, such as cracks or potholes, and determine if slurry coating is the most appropriate solution. The surface is then thoroughly cleaned of all dirt, loose aggregate, and organic debris using power blowers and sweepers. Any significant cracks (over 1/4 inch) or potholes are patched and allowed to cure prior to slurry application.
Our specialized equipment precisely proportions and mixes the asphalt emulsion, fine aggregate (typically volcanic cinder sand or crushed slag for Flagstaff projects), water, and mineral fillers on-site. This ensures a consistent, high-quality mixture that meets the specific requirements of your pavement and the local climate conditions.
The freshly mixed slurry is applied evenly across the prepared asphalt surface using a spreader box or squeegee, depending on the area's size and configuration. We maintain a consistent application rate and thickness, typically between 1/8 to 3/8 inch, to ensure uniform coverage, optimal crack sealing, and a smooth, durable finish.
After application, the slurry coating begins to cure. We establish clear barriers and communicate the recommended curing times. While the surface may be walkable within a few hours, we advise keeping vehicle traffic off for 24-48 hours to allow the emulsion to fully break and the aggregate to set, ensuring maximum adhesion and longevity.
