Asphalt Crack Filling & Sealing
Cracks in your asphalt driveway or parking lot aren’t just cosmetic problems. They’re entry points for water, and in Kokomo’s climate, water is your pavement’s worst enemy. When moisture seeps into cracks and freezes during our cold winters, it expands and pushes the asphalt apart. This freeze-thaw cycle repeats dozens of times each season, turning small cracks into large ones, and eventually creating potholes that require expensive repairs or complete replacement.
Professional asphalt crack repair in Kokomo stops this damage before it starts. Hot rubberized crack filling creates a waterproof seal that flexes with temperature changes, preventing water infiltration and extending your pavement’s lifespan by years. Whether you’re dealing with hairline cracks or wider separations, addressing them now saves you thousands compared to premature resurfacing.
Why Asphalt Cracks Form
Understanding why cracks appear helps you prevent them. Asphalt is a flexible material that expands in summer heat and contracts in winter cold. Over time, this constant movement causes stress fractures. The most common types of cracks we see in Kokomo include:
- Thermal cracks: These run perpendicular to the pavement and result from temperature fluctuations causing the asphalt to contract beyond its tensile strength
- Edge cracks: Form along the perimeter where the asphalt meets grass or gravel, often due to lack of lateral support or poor drainage
- Alligator cracks: Interconnected cracks resembling reptile skin, indicating structural failure of the base layer beneath the surface
- Block cracks: Large rectangular patterns that develop when asphalt oxidizes and loses flexibility
Water accelerates all of these problems. Once it penetrates the surface through any crack, it softens the base material underneath. Vehicle weight then causes the weakened area to shift and settle, making cracks wider and creating the perfect conditions for potholes.
Hot Rubberized Crack Sealing: The Professional Solution
Not all crack filling methods work equally well. Hardware store squeeze bottles and cold-pour products fail quickly because they don’t bond properly or flex with the pavement. Professional crack sealing uses commercial-grade hot rubberized sealant heated to approximately 350-400 degrees Fahrenheit.
This hot application offers several critical advantages. The heat allows the rubberized material to flow deep into the crack, creating maximum contact with the crack walls. As it cools, it forms a flexible, waterproof bond that moves with the asphalt through seasonal temperature changes. Quality hot-pour crack sealants remain pliable in winter cold and won’t soften and track out in summer heat.
The professional crack sealing process includes:
- Crack cleaning: We use high-pressure air or wire brushes to remove dirt, vegetation, and loose debris from inside each crack
- Routing (when necessary): For certain crack types, we create a reservoir to hold more sealant and improve adhesion
- Sealant application: Hot rubberized material is poured directly into the crack using specialized equipment
- Finishing: The sealant is squeegeed or shaped to create a slight crown that sheds water away from the crack
Timing Matters: Fall Crack Sealing in Kokomo
The best time for asphalt crack repair in Kokomo is late summer through fall, before the first freeze. This timing accomplishes several things. First, cracks are typically at their widest during cooler temperatures, allowing more sealant to enter. Second, completing the work before winter prevents water from entering cracks and causing freeze-thaw damage during the coldest months.
Crack sealing requires dry pavement and temperatures above 40-50 degrees Fahrenheit. The asphalt surface must be moisture-free for the sealant to bond properly. Spring is the second-best window, but you’ll want to address winter damage as early as possible to prevent further deterioration during spring rains.
We don’t recommend crack sealing during summer’s hottest weeks. When pavement temperatures exceed 90 degrees, cracks are compressed and at their narrowest. Sealant applied during this time may push out or fail when the asphalt contracts in cooler weather.
Crack Sealing Cost and What Affects Pricing
The cost of professional crack sealing depends on several factors. Most contractors price by linear foot of crack sealed, though some offer project-based pricing for smaller residential driveways. Expect pricing to vary based on:
- Total linear footage: More cracks mean more material and labor time
- Crack width: Wider cracks require more sealant to fill properly
- Accessibility: Easy-to-reach residential driveways cost less than parking lots with limited access
- Pavement condition: Severely deteriorated asphalt may require additional prep work or routing
- Project size: Larger commercial projects typically have lower per-foot costs than small residential jobs
For a typical residential driveway in Kokomo with moderate cracking, professional crack sealing represents a fraction of what you’d pay for patching or resurfacing. Getting a free quote from a licensed and insured contractor lets you understand your specific costs and compare the investment to letting the damage continue.
Pairing Crack Sealing with Sealcoating
Crack sealing and sealcoating work together as a complete pavement preservation strategy. Crack sealing addresses existing damage by preventing water infiltration, while sealcoating protects the entire surface from oxidation, UV rays, and petroleum products.
The proper sequence matters. Always crack seal first, then sealcoat. This allows the crack sealant to cure and ensures the sealcoat covers both the crack filler and surrounding pavement, creating a uniform appearance and complete protection. Attempting to sealcoat over unsealed cracks wastes money—the coating will bridge over cracks temporarily but won’t stop water from entering underneath.
When performed together on the same schedule, these two services maximize your pavement’s lifespan. Most driveways benefit from crack sealing and sealcoating every 2-3 years, though the exact interval depends on traffic, sun exposure, and how well the pavement was constructed initially.
What Crack Sealing Can’t Fix
Professional crack sealing is highly effective preventive maintenance, but it has limits. It works best on cracks less than half an inch wide in structurally sound pavement. Crack sealing cannot repair:
- Alligator cracking: This pattern indicates base failure requiring removal and replacement of the affected area
- Potholes: These need proper patching with hot or cold asphalt mix
- Major settlement: Large sunken areas require base repair before surface treatment
- Severely oxidized pavement: When asphalt has turned gray and brittle throughout, it’s beyond preservation and needs replacement
A qualified contractor will assess your pavement honestly and recommend crack sealing only when it’s the appropriate solution. If your driveway or parking lot has progressed beyond the point where crack sealing provides value, you’ll be advised about patching, overlay, or replacement options instead.
Frequently Asked Questions
How long does crack sealing last?
Quality hot rubberized crack sealant typically lasts 3-5 years when properly applied to well-prepared cracks. Longevity depends on traffic volume, crack width, pavement movement, and weather exposure. Cracks in high-traffic areas or those subject to significant movement may need resealing sooner. Regular inspection each fall helps you identify cracks that need attention before winter arrives.
Can I drive on my driveway after crack sealing?
Hot rubberized crack sealant cools and cures quickly. Most driveways can handle light traffic within 30 minutes to an hour after application. We recommend waiting at least 24 hours before parking heavy vehicles directly on sealed cracks and avoiding sharp turns over fresh sealant. Your contractor will provide specific guidance based on temperature and sealant type used.
Will crack sealant match my asphalt color?
Crack sealant is black but typically doesn’t match the exact shade of your asphalt, especially if your pavement has faded to gray. Fresh sealant appears darker and more noticeable initially. If appearance is a priority, sealcoating the entire surface after crack sealing creates a uniform black finish that makes filled cracks far less visible. Over time, traffic and weather will also help blend the sealant with surrounding pavement.
Should I seal cracks in a new driveway?
New asphalt shouldn’t develop cracks immediately. Most driveways need 6-12 months to cure fully before sealcoating, and cracks typically don’t appear for several years if the pavement was installed correctly. If your new driveway is already cracking, this may indicate installation problems like inadequate base preparation, poor compaction, or mix issues. Contact your installer first, as new pavement is usually under warranty.
Does crack sealing work in winter?
Professional crack sealing requires temperatures above 40-50 degrees Fahrenheit and dry pavement conditions. The asphalt must be warm enough for the sealant to bond properly, and moisture in cracks will prevent adhesion. Winter crack sealing in Kokomo isn’t practical or effective. Emergency pothole patching is possible during winter, but proper crack sealing should wait until spring or fall when conditions are favorable.
How do I maintain sealed cracks?
Sealed cracks require minimal maintenance. Avoid using metal shovels or sharp snow removal tools that might gouge the sealant. Keep the pavement clean and watch for signs that sealant is pulling away from crack edges or developing gaps. When you notice deterioration, schedule resealing before water infiltration resumes. Pairing crack sealing with regular sealcoating every few years provides the best long-term protection and reduces the frequency of crack repair needs.
