Our Crack Sealing Process
Step 1: Assessment & Planning
We inspect pavement condition, map crack locations, note widths/depths, check drainage/traffic flow, and plan phasing to minimize disruption. If areas need patching/overlay first, we flag them.
Step 2: Surface Prep & Cleaning
Cracks are cleared of debris, dust, moisture, and vegetation using air, wire-brushing, or saws. Clean, dry walls ensure maximum adhesion and long-term performance.
Step 3: Routing / Widening (As Needed)
Where appropriate, we route to a uniform reservoir so sealant bonds better and moves with thermal expansion. Spalled edges are trimmed; shallow voids are stabilized.
Step 4: Sealant Selection & Heating
We choose a road-grade, hot-applied rubberized sealant matched to Phoenix temps/traffic. Material is heated to spec for proper viscosity and flow.
Step 5: Installation, Overband & Cure
Sealant is installed to full depth, then lightly overbanded and tooled for edge protection. We allow proper cooling/cure and reopen to traffic once stable.
Step 6: QA, Documentation & Maintenance Plan
Final inspection verifies bond and neat profile. We provide photos/notes and recommend follow-ups (e.g., sealcoating, periodic checks) to extend pavement life.
Common Questions About Our Crack Sealing Process
How wide or deep must a crack be to require sealing?
We typically seal cracks as small as ¼ inch in width. If cracks are too narrow or shallow, we may route or widen them slightly to ensure proper sealant penetration. Very wide or irregular cracks may require partial milling or repair before sealing.
How long does the crack sealing last?
With quality materials and proper installation, crack seals often last 5 to 7 years or more, depending on traffic load, weather exposure, and ongoing maintenance. Pairing crack sealing with sealcoating and surface treatments maximizes longevity.
Will crack sealing leave a visible line on my pavement?
A narrow, clean sealant line is expected. Over time, oxidation helps the sealed line blend in with surrounding asphalt. In many cases, a properly overbanded, flush finish appears nearly seamless.
Can sealing be done in hot summer conditions in Phoenix?
Yes. We schedule work during optimal temperature windows (often early morning or late evening) to prevent sealant from cooling too fast or overheating. Our contractors monitor ambient conditions and material temperature carefully for consistent results.
Can traffic pass over the crack seal immediately?
No. We wait until the sealant cures sufficiently before allowing vehicle or foot traffic. Depending on material and weather, that typically takes anywhere from several minutes to an hour. We may barricade or mark sections until safe.
Do I need to repair cracks before sealing them?
Yes. Cracks with underlying structural failure, potholes, or base damage must be corrected prior to sealing. We assess each area and perform patches or base repairs as needed to support long-term sealing performance.
