How to Prevent Cracks in Your Tarmac Driveway

Tarmac driveways are a popular choice for homeowners in Redhill, Surrey, thanks to their durability, sleek appearance, and cost-effectiveness. However, like any surface exposed to the elements and regular use, tarmac is not immune to cracking. While some wear and tear over time is inevitable, there are steps you can take to minimise the risk of cracks developing in your driveway. In this blog post, we’ll discuss the causes of tarmac cracks and provide practical advice on how to prevent them, ensuring your driveway remains in top condition for years to come.

1. Proper Installation

The foundation of a long-lasting tarmac driveway is proper installation. Ensuring that the sub-base is correctly prepared is crucial for preventing cracks. A well-compacted sub-base provides the necessary support for the tarmac, preventing it from shifting or settling unevenly over time. It’s essential to work with experienced professionals who understand the importance of a solid foundation and who use high-quality materials during the installation process.

2. Regular Maintenance

One of the best ways to prevent cracks in your tarmac driveway is through regular maintenance. This includes keeping the surface clean and free from debris, such as leaves, dirt, and stones, which can cause small indentations or punctures that may develop into cracks. Regularly sweeping your driveway and washing it with water can help maintain its appearance and structural integrity.

3. Sealcoating

Applying a sealcoat to your tarmac driveway can provide an extra layer of protection against the elements. Sealcoating helps to prevent water from seeping into the tarmac, which can cause the material to weaken and crack, especially during freezing and thawing cycles in winter. It also protects against UV damage from the sun, which can cause the tarmac to dry out and become brittle. For the best results, it’s advisable to sealcoat your driveway every two to three years.

4. Prompt Repairs

Even with the best care, minor cracks can occasionally develop in a tarmac driveway. Addressing these cracks as soon as they appear is essential to prevent them from spreading and causing more significant damage. Small cracks can be filled with a quality crack filler, which will seal the gap and stop water from penetrating the surface. Larger cracks or potholes may require professional repair to ensure a seamless and durable finish.

5. Avoid Heavy Loads

While tarmac is designed to withstand regular vehicle traffic, it’s essential to avoid placing excessively heavy loads on your driveway, as this can lead to cracking or indentation. This is particularly important during hot weather when the tarmac surface may soften slightly. If you need to park heavy vehicles or equipment on your driveway, consider using a protective layer, such as boards or mats, to distribute the weight more evenly and reduce the risk of damage.

6. Managing Water Drainage

Water is one of the primary causes of tarmac deterioration. Poor drainage can lead to water pooling on the surface or seeping underneath the tarmac, both of which can cause cracks to develop. Ensure that your driveway has adequate drainage solutions in place, such as sloping the surface to direct water away from the driveway and installing proper guttering and drains. Regularly check these systems to ensure they are functioning correctly and clear any blockages promptly.
