2. Factors that Affect the Cost of a Tarmac Driveway


The size of a tarmac driveway is an important factor to consider when calculating cost. It is a logical expectation that the larger the driveway, the more it will cost. This is because larger driveways require more materials, machinery, and labour. However, the cost per square meter typically decreases as the size of the driveway increases due to the economies of scale. This means that the cost per unit decreases as the quantity increases. For those looking to install a tarmac driveway, it's important to take into account both the size and the cost per unit to get the most value for their money.


The shape of your driveway may not be the first thing that comes to mind when planning tarmac installation, but it can greatly affect the cost. A simple rectangular shape is the easiest and most cost-effective to install, while curves, inclines, and additional features like islands or circles can increase the cost significantly. The reason for this is the extra materials and labour required to create and install a more complex design. Though it may be tempting to go for a unique and intricate design, it’s important to weigh the potential extra costs against the final look and functionality of your driveway. With the right balance, you can create a driveway that’s both visually appealing and cost-effective.

The cost of a tarmac driveway can be influenced by various factors, and among them is the cost of labour. The process of installing a tarmac driveway entails a series of labour-intensive activities. The ground preparation, excavation, and laying of the tarmac require the expertise of skilled personnel. The cost of labour is often determined by the complexity of the project and the level of expertise required. More intricate tarmac designs or larger driveways may require more workers, increasing the overall cost of labour. However, the quality of labour can significantly impact the longevity and durability of the installation, making it a crucial factor to consider when selecting a contractor for your tarmac driveway project.

Material Cost

Material cost is an essential factor in determining the cost of a tarmac driveway. To create a durable and reliable tarmac driveway, quality materials are required, and the cost of these materials can significantly impact the overall cost of the project. A tarmac driveway usually consists of a mix of crushed stones, sand, and bitumen, which are then laid and compacted to create a smooth surface. The cost of these materials can vary depending on the supplier, market trends, and the quality of the materials used. Opting for cheaper and inferior quality materials can save you money in the short term, but it can lead to frequent maintenance and repair costs in the long term. Therefore, it is crucial to factor material costs into the overall cost of the project to ensure a durable, long-lasting, and cost-effective tarmac driveway.



When it comes to installing a tarmac driveway, the level of difficulty can significantly impact the cost. A driveway in a flat, open area with no obstacles will generally be easier and more affordable to install than one in hilly terrain or with multiple curves and turns. Additionally, factors such as the size and slope of the area, as well as any existing drainage systems, can also contribute to the overall cost of a tarmac driveway. However, it is essential to keep in mind that while a more challenging installation may come with a higher price tag, it can also provide additional benefits such as improved functionality and aesthetics. Ultimately, it is important to work with a trusted and experienced contractor who can provide an accurate cost estimate based on your specific project requirements.


Excavation is an essential process in the installation of a tarmac driveway and plays a significant role in determining its cost. During excavation, the ground is cleared and levelled to create a stable base for the tarmac layer, which provides excellent durability, flexibility, and weather-resistant properties. Additionally, excavation allows for the proper installation of drainage systems, which is crucial in preventing water damage to the driveway. However, the cost of excavation will depend on various factors, such as the size of the area, the complexity of the digging, and the type of soil present. Nevertheless, proper excavation is critical in ensuring the longevity of your tarmac driveway, so investing in a reputable contractor with experience in excavation can be worth every penny.


Overall, the cost of installing a tarmac driveway can vary significantly depending on various factors such as labour costs, material costs, excavation and difficulty. It is essential to factor in all these elements when deciding on the installation of your new tarmac driveway in order to ensure that you get a reliable and durable surface that will last for years to come.

To make sure you get the best quality of workmanship at an affordable price, it’s important to hire experienced contractors who are knowledgeable about all aspects involved with installing a tarmac driveway. By doing so, you can rest assured knowing that your investment in this project will be worth every penny!
