Understanding how cracks damage asphalt and why they should not be ignored is the first step in managing your property as a capital asset.
The 7/16” Threshold: When to Act
Question: At what width should asphalt cracks be sealed?
Answer: While hairline cracks are managed through a consistent sealcoating program, structural “working cracks” that reach 7/16” in width require hot-applied rubberized sealant. This width allows for a deep, industrial bond that “locks out” moisture and preserves the integrity of the lime rock base.
The “Funnel” Effect: Bottom-Up Damage
Question: How does water damage asphalt from the bottom up?
Answer: An unsealed 7/16” crack acts as a small funnel during our North Florida thunderstorms, directing water straight into the sub-base. This moisture weakens the asphalt's bond between the binder and the aggregate in that localized zone, leading to fatigue or “alligator cracking” where the pavement eventually collapses under traffic loads.
Surgical Maintenance vs. Expensive Overlays
Preventative maintenance with targeted crack sealing costs far less than having to make large repairs, and, before committing to a major re-paving project, it is vital to know the structural condition of your foundation.
- GoSITE™ Maintenance: We stop cracks from being “funnels” with hot-melt sealant that stops erosion before it spreads.
- InSITE™ Audit: If your lot shows signs of systemic failure—sometimes due to the pipe-clay soils found in North Leon County or improper base installation—paving over the problem will only lead to failure of your new asphalt. Our InSITE™ audit provides the data you need to decide if a localized repair or a full-scale project is necessary.
