Asphalt is a popular choice for roads, driveways, and parking lots because it’s strong, smooth, and cost-effective. But like any surface exposed to weather, traffic, and time, asphalt can develop cracks. These cracks may start small, but they can quickly grow into serious problems if not taken care of. That’s where asphalt crack sealing comes in. This professional service helps extend the life of your pavement, saving you money in the long run and keeping surfaces safe and smooth.
In this blog, we’ll explain why cracks form, how expert crack sealing works, the benefits it brings, and tips for maintaining your pavement. If you want your asphalt to last longer and look better, crack sealing is a smart investment.
Why Do Asphalt Cracks Form?
Understanding the root causes of asphalt cracks can help you see why timely repair is important.
- Weather Changes: Asphalt expands in the heat and contracts in the cold. Over time, this movement causes cracks.
- Water Damage: Rain and melted snow can seep into tiny cracks and freeze. This expands the cracks even more.
- Heavy Traffic: Constant pressure from cars, trucks, and equipment wears down asphalt and creates stress points.
- Poor Installation: If the asphalt wasn’t installed properly or had a weak base, cracks may appear sooner.
- Aging Asphalt: Over the years, asphalt naturally loses its flexibility, making it more likely to crack.
Even minor cracks can grow into potholes or lead to bigger structural damage if ignored. That’s why early crack sealing is key.
What Is Asphalt Crack Sealing?
Asphalt crack sealing is a professional repair process that fills and seals cracks in pavement to prevent further damage. The method involves cleaning the cracks and applying a rubberized sealant that keeps out moisture, dirt, and debris.
This technique is different from crack filling. Crack sealing uses flexible materials that move with the pavement, offering a longer-lasting solution, especially in areas with freezing winters or high traffic.
Crack sealing is one of the most cost-effective ways to maintain your asphalt and extend its usable life.
Benefits of Expert Asphalt Crack Sealing
Hiring a professional for asphalt crack sealing comes with many important benefits:
1. Prevents Further Damage
Sealing cracks blocks water from entering the surface. This stops it from freezing, expanding, and causing more serious pavement problems like potholes and surface erosion.
2. Saves You Money
Early crack sealing is far cheaper than full asphalt resurfacing or replacement. A small investment in maintenance can help you avoid costly future repairs.
3. Improves Safety
Cracked pavement can create tripping hazards or cause vehicles to swerve. Sealed, smooth asphalt makes your property safer for pedestrians and drivers.
4. Boosts Curb Appeal
Freshly sealed asphalt looks clean and well-maintained. Whether it’s a home driveway or a business parking lot, first impressions matter.
5. Extends Pavement Life
Routine crack sealing can add 5 to 10 years to your asphalt’s life, keeping it stronger and more durable over time.
What Happens During the Crack Sealing Process?
Professional asphalt crack sealing follows a careful process to ensure effective, long-lasting results:
Step 1: Inspection
The contractor inspects the pavement to locate all visible cracks and check their depth and width.
Step 2: Cleaning
The cracks are cleaned using wire brushes, high-powered air blowers, or heat to remove dirt, weeds, and debris.
Step 3: Heating (if needed)
In colder climates, cracks may be pre-heated to ensure proper sealant bonding.
Step 4: Sealing
A hot rubberized sealant is applied into the cracks. This flexible material moves with the asphalt as it expands and contracts.
Step 5: Curing
The sealant is allowed to cool and set. In most cases, the area can be reopened to traffic in just a few hours.
Hiring a skilled team ensures each step is done right, giving you the most reliable protection possible.
How Often Should You Seal Asphalt Cracks?
The frequency of crack sealing depends on the condition of your pavement, the climate, and how much traffic it sees. As a general rule:
- Inspect your asphalt at least once or twice a year.
- Seal cracks when they first appear, ideally in the spring or early fall.
- Don’t wait for cracks to spread—early sealing is always more effective.
Professional contractors can help you create a maintenance plan tailored to your property’s needs.
Crack Sealing vs. Crack Filling: What’s the Difference?
Though they sound similar, crack sealing and crack filling are not the same:
- Crack Filling uses a less flexible material and is better for low-movement areas. It’s usually cheaper but doesn’t last as long.
- Crack Sealing uses elastic materials that expand and contract with the pavement, offering longer-lasting protection.
For long-term value and durability, crack sealing is the preferred method—especially for busy roads, driveways, or commercial lots.
Tips to Maintain Your Asphalt After Crack Sealing
After sealing, it’s important to keep your pavement in good shape:
- Keep it Clean: Sweep regularly to remove dirt, leaves, and debris.
- Watch for New Cracks: Small cracks can still form, so check the surface every few months.
- Sealcoat Every Few Years: Adding a sealcoat protects the entire surface and helps prevent new cracks.
- Avoid Heavy Loads: Limit the weight of large vehicles or equipment parked on the asphalt for long periods.
- Fix Drainage Issues: Make sure water runs off the pavement and doesn’t pool in certain spots.
Ongoing care helps protect your crack sealing investment and keeps your asphalt looking great.
