Learn how to repair cracks in concrete driveways like a real pro! A cracked concrete driveway is not just an eyesore—it can lead to more significant damage over time if left unaddressed. The freeze-thaw cycles in South Dakota can cause minor cracks to expand, making repairs essential to maintaining the longevity and curb appeal of your driveway.
Fortunately, fixing cracks in your concrete driveway is a manageable project with the right tools and guidance. In this article, we walk you through the steps to repair your driveway and prevent further damage.
What Causes Concrete Driveways to Crack?
Before jumping into concrete driveway repairs, it’s helpful to understand why concrete damage occurs. Several factors contribute to cracking in concrete driveways:
- Freeze-Thaw Cycles: The harsh winters in Sioux Falls cause water to seep into cracks, freeze, and expand, leading to further concrete spalling and cracking.
- Heavy Loads: Excessive weight from vehicles or equipment can weaken the concrete over time.
- Improper Concrete Installation: If the concrete is not mixed or poured correctly, it may be more prone to cracking.
- Soil Movement: Shifting soil beneath the driveway can cause cracks to form or widen.
- Tree Roots: Growing tree roots can push up against the concrete, causing it to crack or lift.
Driveway Crack Repair Material List:
- Before starting, make sure you have the following materials and tools:
- Wire brush or broom
- Pressure washer or hose
- Putty knife or trowel
- Caulk gun (if using a tube of crack filler)
- Chisel and hammer (for larger cracks)
- Sealer (optional for added protection post driveway crack repair)
- Concrete crack filler (for small cracks)
- Concrete patching compound (for larger cracks)
Concrete Crack Fillers vs. Concrete Patching Compounds
When repairing your concrete driveway, it’s important to choose the right product for the job. Two standard options are concrete crack fillers and concrete patching compounds. While they may seem similar, they serve different purposes.
- Concrete Crack Fillers: These are designed for repairing small cracks (less than 1/4 inch wide). Crack fillers are typically made of liquid or elastomeric materials that penetrate the crack and provide a flexible seal. They help prevent moisture from seeping in and causing further damage but do not add structural strength to the concrete.
- Concrete Patching Compounds: These are used for larger cracks or damaged areas. Patching compounds are thicker and more durable, often containing cement-based ingredients to bond with the existing concrete. They help restore the structural integrity of the surface and provide a more lasting driveway repair.
Choosing the right product depends on the size and severity of the crack. For minor surface cracks, a crack filler is usually sufficient, while deeper or wider cracks require the strength of a patching compound.
How to Repair Cracks in Concrete Driveways:
Step 1: Clean the Crack in Your Driveway
Cleaning your concrete surfaces ensures that the filler or patching compound adheres properly. Follow these steps to prepare the crack:
- Use a wire brush or a chisel and hammer to remove loose debris from the crack.
- Sweep away dust and dirt with a broom.
- Wash the area thoroughly using a hose or pressure washer.
- Let the crack dry completely before proceeding.
Step 2: Choose the Right Driveway Crack Repair Method
- For Small Cracks (Less than 1/4 inch wide): Use a liquid concrete crack filler.
- For Larger Cracks (More than 1/4 inch wide): Use a concrete patching compound.
- For Deep or Structural Cracks: If a crack is deeper than a few inches, it may indicate a structural issue, and you should consult a professional concrete contractor.
Step 3: Apply a Concrete Crack Filler or Patching Compound
For Small Driveway Cracks:
- Cut the tip of the concrete crack filler bottle or tube.
- Load the filler into a caulk gun if necessary.
- Apply the filler directly into the crack, slightly overfilling it.
- Smooth out the filler with a putty knife or trowel.
- Allow it to dry according to the manufacturer’s instructions.
For Larger Driveway Cracks:
- Mix the concrete patching compound according to the manufacturer’s instructions.
- Use a trowel to press the compound into the crack, ensuring it fills all gaps.
- Smooth the surface to blend it with the surrounding concrete.
- Allow it to dry completely before walking or driving on it.
Step 4: Seal the Driveway (Optional but Recommended)
Sealing your driveway helps prevent future cracks and damage from moisture and weather conditions. After your repair has fully cured:
- Choose a high-quality concrete sealer.
- Apply it with a roller or sprayer, following the product’s directions.
- Allow it to dry before using the driveway.
By following these steps, you can repair cracks in your concrete driveway and extend its lifespan. Regular maintenance and prompt repairs will keep your driveway looking great and functioning properly for years to come. If you need professional assistance, don’t hesitate to reach out to a trusted local concrete contractor in Sioux Falls!
How to Prevent Future Driveway Cracks
To extend the life of your driveway and minimize future cracks, consider these maintenance tips:
- Seal Concrete Surfaces Regularly: Applying a sealer every few years protects against moisture, wear, and concrete staining.
- Fill Minor Cracks Promptly: Address small cracks before they grow into larger, more costly problems.
- Avoid Using Deicing Chemicals: Salt and deicers can accelerate freeze-thaw damage.
- Ensure Proper Drainage: Standing water can weaken concrete over time, so make sure your driveway has adequate drainage.
- Be Mindful of Heavy Loads: Avoid parking heavy trucks or equipment on your driveway for extended periods.

While small to medium cracks can often be repaired by homeowners, some issues require professional expertise.
