If you’re considering upgrading your driveway, a tarmac driveway is an excellent choice for its durability, affordability, and sleek appearance. Tarmac (short for tarmacadam) is a popular material for driveways in the UK, known for its ability to withstand the test of time and weather. In this blog, we’ll walk you through the benefits of tarmac driveways, the installation process, and tips for maintaining your new driveway.
1. Durability
Tarmac is renowned for its robustness. It can handle heavy traffic without cracking or deteriorating, making it ideal for busy households or properties with multiple vehicles. It’s also resistant to adverse weather conditions, from scorching summers to freezing winters, ensuring your driveway stays in top shape year-round.
2. Affordability
Compared to other driveway materials like block paving or resin, tarmac is relatively inexpensive. It offers a cost-effective solution without compromising on quality or longevity, making it a great option for homeowners on a budget.
3. Quick Installation
One of the major advantages of tarmac is the speed of installation. A tarmac driveway can often be laid and ready for use within a day or two, depending on the size of the area. This means minimal disruption to your daily life and a quick transformation of your property.
4. Low Maintenance
Tarmac driveways require very little maintenance once installed. Regular cleaning and occasional sealing can keep the surface looking fresh and prevent minor issues from becoming bigger problems.
5. Aesthetic Appeal
With its smooth, black finish, tarmac gives a clean and modern look to your driveway. It can also be edged with other materials like block paving or gravel to add a decorative touch and enhance curb appeal.
1. Planning and Preparation
Before the installation begins, it’s essential to plan the layout and design of your driveway. Consider factors like drainage, the shape of the driveway, and any additional features such as edging or lighting. Proper preparation ensures a smoother installation process and a more durable result.
2. Excavation
The first step in the installation process is excavation. The existing surface is removed to a suitable depth, typically around 150-200mm, to make way for the new tarmac driveway. During this stage, the area is leveled and graded to ensure proper drainage and a stable foundation.
3. Sub-base Installation
A strong sub-base is crucial for the longevity of your tarmac driveway. A layer of crushed stone or hardcore is laid down and compacted to create a solid foundation. This sub-base provides stability and helps prevent future sinking or cracking.
4. Edging Installation
If you’re adding edging to your driveway, this is the time to install it. Edging not only adds a decorative element but also helps contain the tarmac and maintain the shape of the driveway over time. Popular edging materials include block paving, bricks, or stone.
5. Laying the Tarmac
Once the sub-base is prepared and any edging is in place, it’s time to lay the tarmac. The process typically involves two layers: a base course and a wearing course. The base course is a thicker layer that provides structural support, while the wearing course is a finer layer that creates the smooth, finished surface.
The tarmac is spread and leveled using specialized equipment, then compacted with a roller to create a dense, even surface. Proper compaction is key to ensuring the durability and longevity of the driveway.

. Finishing Touches
After the tarmac is laid and compacted, the final touches are applied. This might include creating expansion joints to allow for temperature-related expansion and contraction or adding a sealant to protect the surface from oil spills and UV damage.
7. Curing Time
Once the installation is complete, the tarmac needs time to cure. While the driveway may be usable within 24-48 hours, it’s best to wait a week before parking heavy vehicles on it. This allows the tarmac to fully harden and ensures a longer-lasting finish.
To keep your tarmac driveway looking its best and extend its lifespan, regular maintenance is essential. Here are a few tips:
Regular Cleaning:
Sweep away leaves, dirt, and debris to prevent moss and algae from growing on the surface. Periodically wash the driveway with water and mild detergent to remove stains.
Sealant Application:
Applying a sealant every few years can protect the tarmac from UV rays, oil spills, and water damage. Sealants help preserve the color and texture of the driveway, keeping it looking fresh.
Prompt Repairs:
Address any cracks or potholes as soon as they appear. Small issues can be easily repaired with tarmac patching kits, preventing them from worsening over time.
Avoid Heavy Loads:
While tarmac is durable, it’s best to avoid parking extremely heavy vehicles or equipment on it for prolonged periods, especially during the first few weeks after installation.
