How Do I Permanently Fix A Crack In My Driveway? 10 Best Ways

1. Concrete Resurfacing

Resurfacing is an ideal solution when your concrete driveway has multiple hairline cracks. Instead of removing and replacing the whole slab, a new layer of concrete is poured over the old surface. This process covers existing cracks and rejuvenates the driveway’s appearance.

Before starting, the driveway must be cleaned and any loose concrete removed. A bonding agent is applied to ensure the new surface adheres well to the old one. Then, a fresh concrete mixture is spread evenly using a squeegee or trowel.

After drying for 24 to 48 hours, the driveway will look brand new and be free from visible cracks. This method is budget-friendly and works well for large surface areas. It’s essential to follow manufacturer instructions for the best results.

Pros:

• Long-lasting solution
• Cost-effective
• Covers multiple cracks
• Improves appearance
• Increases home value
• Easy to apply
• Prevents future cracks
  Cons:
• Needs curing time
• May require sealing
• Not for deep cracks

2. Crack Filling with Asphalt Patch

For asphalt driveways, crack filling with a patch compound provides a quick and permanent fix. This method works best for cracks that are 0.5 inches or wider. The patch contains a combination of asphalt and stone aggregate that hardens quickly.

Start by cleaning the crack thoroughly using a wire brush or compressed air. Next, pour the patch mix into the crack and use a tamper to press it down evenly. The surface should be slightly overfilled to allow for compaction.

After patching, allow the area to cure for 24 to 48 hours before using the driveway. This ensures maximum durability and prevents the crack from reappearing. Periodic inspections help maintain the patch in good condition.

Pros:

• Quick application
• Permanent bond
• DIY-friendly
• Weather-resistant
• Affordable materials
• Ideal for asphalt
• Reduces water seepage
  Cons:
• Not for concrete
• Messy if rushed
• May fade over time

3. Concrete Crack Injection

Crack injection is a professional-grade method used for repairing deep concrete cracks. It involves injecting a polyurethane or epoxy resin directly into the crack. This method ensures the crack is filled internally, preventing water penetration and further expansion.

The process begins by drilling small holes into the crack and inserting injection ports. The resin is pumped through these ports using a caulking gun or specialized tool. Once injected, the material expands and hardens inside the crack.

After curing, the filled crack becomes stronger than the surrounding concrete. This solution is best for structural cracks or load-bearing driveways. Always consult a professional if unsure about the severity of the crack.

Pros:

• Deep crack repair
• Prevents water damage
• Strengthens concrete
• Long-term solution
• Seals from inside
• Expands to fill
• Durable under weight
  Cons:
• Requires tools
• Time-intensive
• May need expert help

4. Sealcoating Asphalt Driveways

Sealcoating is an essential maintenance step to extend the life of asphalt driveways. This method not only protects the surface from UV rays and chemicals but also fills in minor cracks. Regular sealcoating prevents the cracks from expanding and becoming severe.

Before applying sealcoat, clean the driveway thoroughly and remove any debris or oil stains. Apply the sealer using a brush, roller, or spray system in thin, even layers. Let the coating dry completely before walking or driving over it.

Sealcoating is best done every 2–3 years, especially in regions with harsh weather. It offers a clean, black finish that improves the driveway’s appearance. Although it doesn’t repair deep cracks, it prevents future ones from forming.

Pros:

• Protects surface
• Fills tiny cracks
• UV resistant
• Easy maintenance
• Enhances looks
• Weather protection
• Affordable upkeep
  Cons:
• Temporary fix
• Requires reapplication
• Not for large cracks

5. Routing and Sealing

Routing and sealing is a method where a crack is widened and deepened before sealing it with a flexible material. This ensures better bonding and prevents the crack from reopening. It’s especially useful for longitudinal cracks in asphalt driveways.

The process starts by using a crack router to create a uniform groove. This groove is then cleaned and filled with hot-pour rubberized sealant. The sealant remains flexible and accommodates temperature fluctuations.

This method provides a long-term seal and reduces the chances of crack expansion. It’s commonly used on highways and commercial pavements. For residential driveways, it offers excellent durability.

Pros:

• Long-lasting seal
• Handles expansion
• Great for asphalt
• Used commercially
• Prevents spreading
• Professional finish
• Weather-tolerant
  Cons:
• Requires machinery
• Not DIY-friendly
• May need permits

6. Concrete Caulking

Caulking cracks in concrete driveways is a simple and effective solution for small to medium-sized cracks. It involves using polyurethane or silicone-based sealants that remain flexible after drying. This flexibility allows the seal to expand and contract with temperature changes.

Clean the crack thoroughly before applying the caulk. Use a caulking gun to apply the material evenly and smooth it with a putty knife. Let it dry as per product instructions to ensure maximum adhesion.

This method is great for homeowners looking for a quick fix. It also works well in combination with resurfacing methods. Although not suitable for structural cracks, it keeps surface-level cracks sealed tightly.

Pros:

• Simple process
• Flexible seal
• Ideal for DIY
• Fast results
• Low cost
• Easy to find
• Works on concrete
  Cons:
• Not for deep cracks
• May need redoing
• Less durable

7. Infrared Asphalt Repair

Infrared asphalt repair is a modern method that uses infrared technology to heat and blend new asphalt into existing surfaces. This technique creates a seamless patch, making it nearly invisible. It works best for surface cracks and shallow potholes.

The area is first heated using infrared panels until the asphalt becomes pliable. New asphalt is added, mixed in, and compacted to ensure a level finish. The repair is ready for traffic in just a few hours.

This method is ideal for commercial driveways and high-traffic areas. It provides a permanent repair with excellent bonding. However, specialized equipment is required, making it a job for professionals.

Pros:

• Seamless patch
• Fast process
• Great for asphalt
