Crack Filling & Sealing Services in Charlotte NC

Cracks in asphalt pavement may seem minor at first, but they are the first signs of deterioration.

Left untreated, they allow water to seep in, leading to further damage, potholes, and costly repairs. Regular asphalt crack filling and sealing helps extend the lifespan of your pavement, preventing small cracks from becoming major structural problems.

At SMI Paving, we specialize in asphalt crack repair services, using high-quality materials and proven techniques to protect your pavement from weather, moisture, and daily wear. Whether for a commercial parking lot or a residential driveway anywhere in Charlotte, our crack filling and sealing solutions help preserve the integrity of your asphalt.

Why You Shouldn’t Ignore Cracks in Your Pavement

Over time, all asphalt will develop cracks due to factors like traffic, weather changes, and aging. The key is addressing cracks early before they expand and weaken the pavement structure.

  • Prevents Moisture Damage: Water infiltration is the leading cause of asphalt failure. Cracks allow water to reach the subbase, leading to further cracking and potholes.
  • Extends Pavement Lifespan: Regular maintenance, including crack filling and sealing, can more than double the life of your asphalt.
  • Reduces Repair Costs: Filling and sealing cracks early prevents the need for more extensive repairs like resurfacing or complete replacement.
  • Improves Safety: Cracks can cause uneven surfaces, increasing the risk of tripping hazards and vehicle damage.

Ignoring cracks will only lead to greater damage and increased costs. A proactive approach to crack filling and sealing ensures long-term pavement durability.

Crack Filling vs. Crack Sealing

There are two primary methods for repairing cracks in asphalt: crack filling and crack sealing.

While both help prevent further damage, they serve different purposes.

What is Asphalt Crack Filling?

Crack filling is used for non-working cracks (cracks that don't experience significant movement). This process involves filling cracks with a durable asphalt patch material, reinforcing the surrounding pavement.

  • Ideal for cracks that have been neglected for a while
  • More cost-effective than full pavement replacement
  • Typically used as a temporary fix for non-moving cracks

What is Asphalt Crack Sealing?

Crack sealing is a preventative maintenance method that uses a hot, rubberized sealant to flex with the pavement as it expands and contracts. This process effectively prevents moisture infiltration.

  • Best for active cracks that continue to widen over time
  • Creates a flexible, waterproof barrier
  • Extends pavement life by reducing the impact of seasonal changes

Both methods are essential parts of asphalt crack repair, and choosing the right approach depends on the type and severity of the cracks in your pavement.

Best Candidates for Asphalt Crack Filling and Sealing

Not all cracks can be filled or sealed. Here's how to determine if your pavement is a good candidate for crack repair:

  • Cracks less than ¾ inch wide: Small to medium cracks can typically be sealed or filled effectively.
  • Pavement with minimal structural damage: If the foundation is still intact, crack repair is a great solution.
  • Cracks showing little to no crumbling at the edges: Severe crumbling or potholes may require more extensive repairs.

If cracks are too wide, deep, or widespread, asphalt resurfacing may be necessary instead of simple crack sealing.

Common Causes of Cracking

Cracks develop for a variety of reasons, and understanding the cause can help prevent repeat damage after a repair. Regular wear from vehicle traffic gradually breaks down the surface, while temperature swings between hot Carolina summers and occasional winter freezes cause asphalt to expand and contract. Tree roots growing beneath a driveway or parking lot can also push cracks up from below, and pavement that's simply reached the end of its expected lifespan tends to crack more easily as the asphalt becomes brittle. Identifying the underlying cause helps determine whether crack filling and sealing is enough, or whether a larger repair is needed.

Preventative Maintenance: The Key to Long-Lasting Asphalt

A routine asphalt maintenance program is the best way to extend the life of your pavement.

  • Annual Inspections: Check your asphalt for cracks and signs of deterioration every year.
  • Sealcoating Every 2-3 Years: A fresh sealcoat protects asphalt from moisture, UV rays, and chemicals.
  • Regular Crack Repairs: Addressing cracks as soon as they appear prevents them from worsening.

Proactive maintenance is far more cost-effective than waiting until your pavement requires complete replacement.

FAQs

How often should I have my asphalt cracks repaired?

It's recommended to inspect your pavement annually and fill or seal cracks as soon as they appear. Regular maintenance prevents small cracks from turning into costly damage.

What is the best time of year for crack sealing?

The ideal time for asphalt crack sealing across the Carolinas is during warmer months, typically spring through early fall. Warmer temperatures allow the sealant to adhere properly and cure effectively.

Can crack sealing be done on all asphalt surfaces?

Most asphalt surfaces can benefit from crack sealing, but some severe cracks may require more extensive repairs. We assess each pavement to determine the best solution.

Will crack filling or sealing make my pavement look new again?

Crack repair improves the appearance of asphalt, but it does not create a completely new surface. For a like-new look, sealcoating after crack repair is recommended.

How long does asphalt crack sealing take to dry?

Crack sealing typically takes a few hours to dry, but it's best to allow 24 hours before heavy traffic resumes on the surface.

Can I fill cracks myself with a DIY kit?

DIY crack fillers can offer a short-term fix for very minor cracks, but they typically don't bond or flex the way professional-grade materials do. Without proper cleaning and preparation, DIY repairs often fail within a year, allowing water back into the crack and undoing the fix entirely.
