How to Fix a Cracked Driveway Paving Stone

To fix a cracked driveway paving stone, clean the area thoroughly and choose an appropriate filler like concrete crack repair for small cracks or cement for larger ones. Once filled, allow the filler to set for 24 hours before use.

Identifying the Crack

To accurately identify cracks in your driveway paving stones, start by examining the surface closely. Different types of cracks require different repair methods, so it’s essential to know what you’re dealing with.

Types of Cracks:

• Hairline Cracks: These are very fine and often caused by surface stress.
• Minor Cracks: Cracks under ½ inch wide can usually be repaired with DIY methods.
• Large Cracks: Cracks over ½ inch wide might need professional repair.
• Chipping and Spalling: Edges that have chipped off or surface flaking often indicate that the material is degrading.

Look for the following indicators to classify the cracks:

• Width and Depth: Measure the crack to determine its size.
• Pattern: Note if the crack is branching or localized.
• Location: Check if the cracks are on the edges or the center of the paving stones.

For additional tips on identifying and evaluating cracks, you can refer to Best Practices for Installing Pavers on our blog.

Evaluating Cracks:

• Use a measuring tape to check the width.
• Inspect the crack in different lighting conditions to get a clear view.
• Determine if external factors like tree roots or water drainage could be causing the damage.

By understanding the type and extent of the cracks, you can choose the most effective repair method. Cleaning up the area beforehand ensures that the repair material adheres properly. If the damage is extensive or too complex, it’s wise to consult a professional.

Preparing the Area

Preparing the area for repair is crucial to ensure the best results. Follow these steps:

1. Clear the Area: Remove any furniture, decorations, or obstructions from the area to be repaired.
2. Clean the Surface: Use a hose or a low-powered pressure washer to remove dirt, dust, and mold. For stubborn grime, use a mild detergent.
3. Remove Debris: Employ a shop vac to clear out any residue left in the cracks.
4. Weed Removal: Remove any vegetation growing in the cracks with a weed remover tool.
5. Dry the Surface: Allow the area to dry completely to ensure the best adhesion for repair materials.

Repairing the Crack

To fix a cracked driveway paving stone, prompt action is essential, especially before winter. Follow these steps to ensure a thorough repair:

1. Assess: Determine if the cracks result from settling or shifting. If so, seek professional help for mud-jacking or consider replacing sections.
2. Clean:

• Use a hose with a nozzle or a low-powered pressure washer to remove dirt and mold.
• Employ a shop vac to eliminate any residue.
• Remove any vegetation from the cracks with a weed remover.

3. Dry: Allow the cleaned cracks to dry completely before proceeding.
4. Choose the Right Filler:

• For cracks up to ½ inch wide and ¼ inch deep, use a concrete crack repair product like Sakrete’s Concrete Crack Filler.
• Smaller cracks can be filled with a liquid crack filler.
• Larger cracks may need fresh cement or an epoxy. Cement is suitable for flat surfaces, while epoxy works well for vertical ones.

5. Fill the Cracks:

• Wearing protective gear (gloves, mask, goggles), apply the chosen filler carefully.
• For fine surface cracks, consider using a resurfacing product like Quikrete’s Concrete Resurfacer.
• Widen small cracks slightly with a hammer and chisel before cleaning and applying the sealant.
• For cracks with crumbling edges, clean thoroughly and use quick-setting cement mixed with an acrylic fortifier.

6. Separated Control Joints:

• Fill these with an advanced polymer self-leveling sealant.
• Insert a foam backer rod if joints are over ½ inch wide to maintain integrity and aesthetics.

7. Wide, Uneven Cracks: May indicate structural issues requiring slab replacement. Remove the damaged section, form new molds, add a gravel base, and pour new concrete for durability.

Finishing Touch: Allow the filler to set for 24 hours before using the driveway. Prompt crack repair prevents further damage, weed growth, and maintains a tidy appearance. For more information on repair materials and techniques, you can check out How Substrate Affects Paver Stability.

By following these steps, homeowners can effectively restore their driveway and prevent further issues.

Sealing and Maintenance

Once you’ve repaired the cracked paving stone, it’s crucial to seal the area to prevent future damage. Start by choosing the right sealer based on your paver type:

• Joint Sand Pavers: Use a water-based sealer to harden the joint sand and create a solid seal over the pavement.
• Non-Porous Smooth Stones: Opt for a solvent sealer, which will darken the stones and give a glossy finish.

Before applying the sealer, ensure the area is thoroughly cleaned. Wash the pavers to remove dirt and debris. For the best results, the sealer should be applied evenly:

• Sprayer: Ideal for water-based sealers to cover joint sand.
• Roller: Suitable for solvent sealers on non-porous stones.

Routine maintenance is key to prolonging the life of your driveway. Follow these tips:

• Regular Cleaning: Sweep and hose down the driveway to remove dirt and weeds.
• Check for Cracks: Inspect regularly and address small cracks before they worsen.
• Reapply Sealer: Depending on traffic and weather conditions, reapply the sealer every 2-3 years.
