What Is Tar and Chip, and How Does It Compare to Gravel?

When it comes to choosing a driveway surface, homeowners have a range of options, each offering its own benefits and aesthetic appeal. Two popular choices are tar and chip and gravel driveways. While they may appear similar at first glance, these surfaces have key differences in terms of cost, durability, maintenance, and appearance. At NS Driveways Weybridge, we specialise in providing tailored driveway solutions across Weybridge, Surrey, helping homeowners choose the best surface for their needs. In this blog, we’ll explore what tar and chip entails and how it compares to gravel, offering insight into which option might be right for your driveway.

1. What Is Tar and Chip?

Tar and chip, also known as chip seal, is a type of driveway surface that combines hot liquid bitumen (tar) with a layer of stone chips. The process involves spreading a layer of hot bitumen over a prepared base, followed by a layer of stone chips, which are then compacted to adhere firmly to the tar. This creates a textured, hard-wearing surface that offers a natural, rustic appearance.

• Durable Surface: The combination of bitumen and stone chips makes tar and chip a durable option that can withstand daily wear and tear. It is resistant to water penetration and can handle the weight of vehicles, making it suitable for residential driveways.
• Customisable Appearance: One of the advantages of tar and chip is its customisable appearance. The colour and size of the stone chips can be selected to create a look that complements your home’s exterior, offering a range of aesthetic possibilities.
• Cost-Effective: Tar and chip driveways tend to be more affordable than asphalt, making them a budget-friendly option for those seeking a long-lasting surface without the higher price tag.

2. What Is Gravel?

Gravel driveways are one of the most traditional and widely used driveway surfaces. A gravel driveway consists of a layer of loose, small stones spread over a prepared base. Gravel is typically installed over compacted soil or a sub-base to ensure stability.

• Natural Look: Gravel offers a natural and informal look that blends well with rural and country-style properties. The variety of colours and sizes of gravel stones available allows for customisation, similar to tar and chip.
• Affordable Installation: Gravel is one of the most affordable options for driveway surfaces, making it a popular choice for those who want a simple and quick solution. The initial cost of materials and installation is generally lower than that of tar and chip.
• Easy to Refresh: If a gravel driveway starts to look worn or compacted, it can be easily refreshed by adding another layer of gravel, which helps to maintain its appearance.

3. Comparing Durability: Tar and Chip vs. Gravel

When choosing a driveway surface, understanding the durability of each option is essential, particularly for those in areas like Weybridge, Surrey, where weather conditions can vary significantly throughout the year.

• Tar and Chip: The hardened bitumen layer beneath the stone chips provides a more stable surface than loose gravel. This means that tar and chip driveways are less likely to shift or develop ruts over time. The bitumen also acts as a protective barrier, helping to prevent water from penetrating the base and causing erosion.
• Gravel: While gravel driveways can be durable if properly installed and maintained, they are more prone to displacement due to traffic and weather. Heavy rain or frequent vehicle use can cause the stones to shift, creating ruts and uneven areas. Regular raking and topping up of gravel are often required to maintain a smooth surface.

For homeowners seeking a driveway that requires less maintenance and can handle regular use, tar and chip may be the better option in terms of long-term durability.

4. Maintenance Requirements

Maintenance is a key consideration for many homeowners when choosing a driveway surface, as it can impact the time and cost involved in keeping the driveway looking its best.

• Tar and Chip Maintenance: Tar and chip driveways require minimal maintenance once installed. Occasional sweeping to remove debris and the rare addition of extra stone chips are generally all that’s needed to maintain its appearance. The compacted nature of the surface means that there is less need for frequent adjustments.
• Gravel Maintenance: Gravel driveways require more regular attention to keep them in good condition. The loose nature of gravel means that stones can migrate over time, leading to thinning in some areas. Raking the gravel back into place and adding new gravel periodically are necessary to maintain an even surface.

While gravel driveways can be easily refreshed, the ongoing maintenance may be a drawback for those looking for a low-maintenance solution. Tar and chip driveways, by contrast, offer a more stable surface with fewer maintenance demands.

5. Cost Considerations

Understanding the cost differences between tar and chip and gravel can help you make a more informed decision based on your budget.

• Initial Installation Costs: Gravel driveways are typically more affordable to install initially. The materials are relatively inexpensive, and the installation process is straightforward, making it an attractive option for budget-conscious homeowners.
• Long-Term Costs: Tar and chip may have a higher upfront cost compared to gravel, but it often proves to be more cost-effective in the long run due to its durability and lower maintenance requirements. The reduced need for frequent top-ups and adjustments can make tar and chip a better investment over time.

Conclusion
