How to Repair Small Cracks in Your Tarmac Driveway Before They Spread

Tarmac driveways are popular due to their durability and low maintenance requirements. However, like any surface exposed to the elements, they are not immune to damage over time. Small cracks are a common issue, and if left untreated, they can grow into larger problems that may require costly repairs. Addressing these cracks early can prevent further damage and maintain the overall appearance and integrity of your driveway. In this article, we’ll guide you through the process of repairing small cracks in your tarmac driveway before they spread.

Why Do Cracks Appear in Tarmac Driveways?

Before diving into repairs, it’s important to understand why cracks form in tarmac driveways in the first place. Several factors can contribute to the development of cracks, including:

• Weather conditions: Extreme temperature changes, such as freezing and thawing cycles, can cause the tarmac to expand and contract, leading to cracking.
• Heavy traffic: Frequent use by heavy vehicles or machinery can put stress on the surface, causing small cracks to form.
• Age of the driveway: Over time, tarmac naturally breaks down due to wear and tear, making it more susceptible to cracks and other forms of damage.
• Water infiltration: Water can seep into the cracks, eroding the underlying base and causing the cracks to widen over time.

How to Repair Small Cracks in Your Tarmac Driveway

If you’ve noticed small cracks in your tarmac driveway, it’s best to take action as soon as possible to prevent them from spreading. Here’s a step-by-step guide to help you repair these cracks effectively.

1. Clean the Area Around the Crack

Before beginning any repairs, ensure that the crack and surrounding area are free from dirt, debris, and loose tarmac. Use a broom or a leaf blower to clear the surface. For deeper cracks, you can use a wire brush to loosen any debris that might be stuck inside the crack. Cleaning the area thoroughly will ensure that the repair material adheres properly to the surface.

2. Remove Loose or Damaged Tarmac

If there are any pieces of loose or damaged tarmac around the crack, remove them using a chisel or a similar tool. You want the area to be smooth and free of loose fragments so that the repair material can bond properly.

3. Apply a Crack Filler or Tarmac Repair Product

Once the area is clean, apply a crack filler designed for tarmac surfaces. These products are available in a variety of forms, such as liquid fillers or pre-mixed tarmac repair compounds. For small cracks, a liquid filler may be sufficient, as it will seep into the crack and seal it effectively. For larger or deeper cracks, you may need to use a thicker compound that can fill the void and provide a more durable solution.

Follow the manufacturer’s instructions on how to apply the product. In most cases, you’ll need to pour or spread the filler into the crack and smooth it over with a trowel or spatula. Make sure the filler completely covers the crack and is level with the surrounding tarmac.

4. Allow the Repair to Dry

After applying the crack filler, allow it to dry for the time specified by the manufacturer. This is typically between 4 to 24 hours, depending on the product used and the weather conditions. During this time, avoid walking or driving over the repaired area to ensure the filler sets properly.

5. Seal the Driveway

Once the crack filler has fully cured, it’s a good idea to seal the entire driveway to protect the repaired areas from future damage. Tarmac driveway sealers create a protective barrier that can prevent water infiltration and UV damage. Applying a sealer will help prolong the life of your driveway and reduce the chances of new cracks appearing.

To apply the sealer, use a roller or sprayer, depending on the product you’ve chosen. Make sure to cover the entire surface evenly and allow it to dry as per the manufacturer’s guidelines.

When to Call a Professional

While repairing small cracks in your tarmac driveway is something that many homeowners can do themselves, there are situations where calling in a professional is the best option. If you notice that the cracks are extensive, deeper than a few millimetres, or affecting the overall structure of your driveway, it’s time to seek expert help. Professionals have access to high-quality materials and equipment that can ensure a long-lasting repair, especially for larger or more complex issues.

Conclusion

Maintaining the integrity of your tarmac driveway is essential to prevent small cracks from developing into more serious problems. By addressing cracks promptly, you can preserve the aesthetic appeal and structural stability of your driveway for years to come. Regular inspections and repairs can save you money in the long run by preventing larger, more expensive issues.
