Cracks in asphalt may seem minor at first—but when left unsealed, they allow water to reach the base layer, causing erosion, potholes, and structural breakdown.
Asphalt Crack Sealing in the Greater Denver Area
Mcnally Asphalt & Paving Company provides professional crack sealing services across the Greater Denver area to help commercial property managers, HOAs, and homeowners protect their pavement before small problems turn into costly asphalt repairs.
Crack sealing is one of the most important long-term strategies in pavement maintenance. We use a hot-applied, rubberized sealant that fills each gap and bonds to the surrounding material, allowing it to flex with seasonal changes. This prevents further expansion, reduces oxidation, and keeps water from penetrating the surface—extending the life of your pavement and reducing the need for major restoration work.
Crack Sealing vs. Filling
Though often used interchangeably, crack sealing and filling are two distinct techniques, and choosing the right one depends on the movement and condition of the pavement.
Crack sealing uses flexible, rubberized materials that expand and contract with the pavement. This method is best for active or “working” cracks caused by temperature swings and freeze-thaw cycles—especially common in Colorado’s climate. It’s the preferred approach for long-term durability on commercial parking lots and high-traffic drive lanes.
Crack filling, on the other hand, is used for non-moving or “static” cracks and involves a less elastic material. It’s a quicker, more cost-effective option for asphalt driveways or older surfaces with minimal shifting.
At Mcnally Asphalt & Paving Company, we inspect each paved area to determine the best repair strategy. In many cases, we combine both sealing and filling to address multiple types of damage across the same parking lot or roadway.
Why Sealing Cracks in Asphalt Matters
This asphalt repair does more than stop cracks from spreading—it protects the entire structure of the pavement.
By sealing off entry points for water it prevents base damage, slows surface wear, and reduces the formation of potholes. It also preserves the appearance of your lot and helps prep the surface for future treatments like sealcoating or resurfacing.
We commonly pair crack sealing with sealcoating, minor patching, or parking lot repair for commercial lots in Parker, HOA roadways in Castle Rock, and long residential driveways in Aurora. By addressing cracks early, Mcnally Asphalt & Paving Company helps Central Colorado property owners maximize the value of their pavement.
