Key Takeaways

  • Different types of cracks in concrete driveways indicate different underlying issues.
  • The right filler should be chosen based on the size and depth of the crack.
  • The cracked area should be thoroughly cleaned and debris should be removed before applying the filler.
  • After applying the filler, a sealant should be applied to protect the repaired area from water and contaminants.

Assessing the Damage: Identifying the Types of Cracks

You can quickly identify the types of cracks in your concrete driveway by examining their width and direction. Understanding the types of cracks will help you determine the causes and find the appropriate solutions.

There are several common types of concrete cracks that you may encounter. First, there are hairline cracks, which are thin and shallow. These cracks are usually caused by shrinkage during the curing process or temperature fluctuations.

Second, there are settlement cracks, which are wider and deeper. These cracks occur when the ground beneath the concrete shifts or settles.

Lastly, there are structural cracks, which are the most severe. These cracks may indicate underlying structural issues and require professional assessment and repair.

Gathering the Necessary Tools and Materials

To get started, you'll need a few essential tools and materials for this project.

First, you'll need to choose the right filler for your concrete cracks. There are different types of fillers available, such as epoxy-based fillers, latex- or polymer-based fillers, and concrete crack sealants. Consider the size and depth of the cracks when selecting the filler.

Next, you'll need to properly mix the concrete. Start by wearing protective gloves and goggles. Follow the manufacturer's instructions on the concrete mix bag to determine the proper ratio of water to mix. Use a mixing container and a mixing paddle to combine the water and mix until you achieve a smooth consistency. Avoid adding too much water as it can weaken the concrete.

Once the concrete is properly mixed, you're ready to fill the cracks in your driveway.

Preparing the Cracked Area: Cleaning and Removing Debris

Make sure the cracked area is thoroughly cleaned and free from any debris or loose particles. Cleaning techniques are crucial to ensure a strong and long-lasting repair.

Begin by using a broom or brush to sweep away any loose dirt, leaves, or grass.

Next, use a high-pressure hose or power washer to remove any stubborn stains or dirt. For tougher stains, you may need to use a mild detergent or concrete cleaner. Scrub the area gently with a stiff brush and rinse thoroughly.

Proper debris disposal is also important. Collect any debris or waste material and dispose of it in accordance with local regulations. Avoid dumping it into drains or water bodies.

Keeping the cracked area clean and free from debris will help create a solid foundation for the repair process.

Applying the Concrete Crack Filler: Step-by-Step Instructions

Ensure that the cracked area is completely dry before applying the concrete crack filler. This is crucial for the effectiveness of the repair.

To begin, clean the crack thoroughly using a wire brush or a high-pressure washer to remove any loose debris or particles.

Next, use a chisel or a grinder to widen the crack, creating a V-shaped groove. This will allow the filler to properly adhere and prevent it from popping out over time.

Once the crack is prepared, carefully apply the concrete crack filler, following the manufacturer's instructions. Use a putty knife or a trowel to push the filler into the crack, ensuring it's completely filled.

Smooth the surface and allow it to dry for the recommended time.

Remember to avoid common mistakes such as applying the filler in wet conditions or not filling the crack completely.

Finishing Touches: Sealing and Protecting the Repaired Cracks

Once the crack filler has dried, you can seal and protect the repaired area by applying a clear coat or a waterproofing sealant.

Sealing the cracks is an essential step in the long-term maintenance of your concrete driveway. By applying a clear coat or a waterproofing sealant, you create a protective barrier that prevents water, dirt, and other contaminants from seeping into the cracks. This helps to prevent further damage and extends the lifespan of your driveway.

When choosing a sealant, consider the specific needs of your driveway. Clear coats provide a glossy finish while waterproofing sealants offer enhanced protection against water damage.

Apply the sealant evenly using a brush or a roller, making sure to cover the entire repaired area. Allow the sealant to dry completely before using your driveway.

Regularly inspect and reapply the sealant as part of your long-term maintenance routine to ensure the continued protection of your concrete driveway.


In conclusion, by following the systematic steps outlined in this guide, you can effectively fix cracks in your concrete driveway.

Assess the damage, gather the necessary tools and materials, prepare the cracked area by cleaning and removing debris, apply the concrete crack filler with precision, and finish off by sealing and protecting the repaired cracks.

With these techniques, your concrete driveway will regain its structural integrity and aesthetic appeal.
