Asphalt Crack Sealing & Crack Filling
The single highest-leverage pavement maintenance you can do. Hot-rubber crack sealing keeps water out of the pavement base — the #1 cause of structural failure in Connecticut winters.
Why Crack Sealing Is the Highest-Leverage Repair
Pavement failure starts with water reaching the base layer. Once that happens, freeze-thaw cycles widen the failure exponentially, and repair cost goes up 5-10x. Crack sealing is what prevents that from happening in the first place.
Blocks water infiltration
Hot-rubber sealant stays flexible and bonds to the crack walls, sealing out water through freeze-thaw cycles.
Stops crack expansion
Unsealed cracks widen 30-50% per year through freeze-thaw. Sealed cracks are stabilized.
Extends pavement life 3-5 years
When done early and on schedule, crack sealing adds years to overall pavement life.
Cheapest pavement maintenance available
A $0.50/foot crack-sealing job prevents a $50/sq ft reconstruction down the road.
Required before sealcoat
Sealcoat is a thin protective layer — it doesn't fill cracks. Crack sealing has to happen first.
Maintains structural integrity
Keeps the asphalt and base layer intact, preventing the cascade failures that lead to potholes and reconstruction.
Crack Sealing Methods
Different crack types need different approaches. We pick the right method for each crack, not a one-size-fits-all treatment.
Hot-Applied Crack Sealing
Best for working cracks that move with temperature changes. Rubberized hot-pour sealant applied at ~380°F for maximum adhesion and flexibility. Typical longevity: 5-8 years.
Cold-Applied Crack Filling
Ideal for stable, non-working cracks. Emulsion-based filler penetrates deep into cracks. Faster to deploy, lower cost, typical longevity 2-3 years.
Rout & Seal
For severely deteriorated cracks. We rout the crack to create a clean reservoir for maximum sealant volume, then apply hot-rubber sealant. Most durable repair for deteriorated cracks.
Our Crack Sealing Process
Crack assessment
Walk the lot, identify crack types (working vs. stable), measure severity, and recommend the right treatment for each.
Preparation
Clean cracks with compressed air, route severely deteriorated cracks where needed. Vegetation removed.
Sealant application
Apply hot-rubber or cold-pour sealant with professional equipment, ensuring full crack penetration.
Cure & reopen
Hot-rubber sealant typically cures in 30-60 minutes; lot back in service quickly. Cold-pour needs a bit longer.

Crack Sealing FAQs
When should cracks in asphalt be sealed?
Cracks should be sealed as soon as they appear to prevent water from reaching the pavement base. Early intervention is the cheapest, highest-leverage pavement maintenance you can do — a $50 crack-sealing job today often prevents a $5,000 reconstruction in three years.
What is the difference between crack sealing and crack filling?
Crack sealing uses hot-applied rubberized sealant for working cracks — cracks that move with temperature changes. The sealant flexes with the pavement. Crack filling uses cold-applied emulsion-based material for stable, non-working cracks that don't move. We pick the method based on the crack type.
How long does crack sealing last?
Professional hot-rubber crack sealing typically lasts 3-8 years, depending on traffic load, climate, and the original crack severity. Our DOT-grade materials and proper edge preparation get the long end of that range.
Do you handle large commercial crack sealing projects?
Yes — we routinely handle large-scale commercial and municipal projects including airports, highways, and multi-acre commercial lots throughout Connecticut. Professional-grade melters and applicators let us cover ground quickly.
Should I crack seal before sealcoating?
Yes — always. Sealcoat is a thin protective layer over the pavement surface; it doesn't fill cracks. Crack sealing has to happen first, given time to cure, then the sealcoat goes on top. Skipping crack sealing means water still gets in even with fresh sealcoat.
