How to Get a Smooth, Professional Tarmac Finish

When it comes to creating a driveway that is both durable and aesthetically appealing, tarmac is one of the best materials to consider. Tarmac driveways provide a sleek, smooth finish that enhances the curb appeal of your home. However, to achieve that professional look, it’s essential to follow the right techniques during the installation process. At Halesworth Driveway Contractors, we specialise in providing top-quality tarmac driveways that not only meet but exceed our clients’ expectations. In this blog, we’ll discuss how to get a smooth, professional tarmac finish for your driveway and the key factors that contribute to a flawless result.

1. Proper Preparation of the Subbase

The foundation of any tarmac driveway is the subbase, which plays a critical role in ensuring the durability and smoothness of the finished surface. If the subbase is not prepared correctly, it could lead to an uneven surface or issues such as cracking and subsiding.

Steps for Preparing the Subbase:

• Excavation: The first step is to excavate the area to a depth of at least 100mm (depending on the traffic load and ground conditions). This will provide enough space for the subbase and tarmac layers.
  
• Subbase Material: A crushed stone or gravel subbase is essential to support the weight of the tarmac and ensure proper drainage. The subbase should be compacted firmly to create a solid foundation.
  
• Compaction: Using a mechanical roller or plate compactor, the subbase should be compacted evenly to remove any air pockets and ensure a stable base for the tarmac.
  

2. Choosing the Right Tarmac Mix

There are various types of tarmac available, and selecting the right mix is key to achieving a smooth, professional finish. The type of tarmac used depends on the level of traffic expected on the driveway and the overall aesthetic you want to achieve.

Common Types of Tarmac:

• Standard Hot Rolled Asphalt (HRA): Ideal for residential driveways and low-traffic areas. It provides a smooth finish and is cost-effective.
  
• Dense Bitumen Macadam (DBM): This is a more durable option, suitable for areas with heavy traffic or where greater strength is needed.
  
• Coloured Tarmac: Available in a range of colours, this type of tarmac can be used to add a personal touch to your driveway.
  

3. Laying the Tarmac

The application of tarmac is a highly skilled job that requires precision to ensure an even, smooth finish. Laying the tarmac too thick or too thin can lead to imperfections, so it is crucial to follow the correct procedure.

Key Steps for Laying Tarmac:

• Temperature Control: Tarmac should be laid at the right temperature for optimum results. If the temperature is too low, the tarmac may harden too quickly and not bond properly. Conversely, laying tarmac in very hot conditions can result in an uneven finish.
  
• Even Distribution: The tarmac should be spread evenly over the subbase to a consistent thickness. A professional contractor will use a mechanical spreader to ensure an even layer.
  
• Compaction: After the tarmac is laid, it needs to be compacted using a roller to remove any air pockets and ensure a smooth, solid surface. This is the key step in achieving a professional finish.
  

4. Edging and Finishing Touches

The edges of your tarmac driveway are just as important as the main surface. Properly finished edges enhance the overall appearance and prevent the tarmac from breaking away at the borders.

Steps for a Clean Finish:

• Edge Restraints: Edge restraints are important to keep the tarmac in place and prevent the material from spreading over time. Concrete, timber, or metal edging can be used depending on your preference.
  
• Finishing: After the tarmac has been laid and compacted, the surface should be smoothed out and any imperfections should be corrected. This is done by hand or with a trowel, ensuring that the driveway has an even, flawless surface.
  

5. Allow Time for Curing

After the tarmac is laid and finished, it is essential to allow it time to cool and cure before it is used. This typically takes 24 to 48 hours, depending on the weather conditions.

Important Considerations:

• Avoid heavy traffic: During the curing process, avoid driving or parking on the tarmac to prevent deformation.
  
• Allow for settling: The surface will settle further over the first few weeks. You may notice some minor indentations, but these should naturally smooth out as the tarmac fully hardens.
  

6. Regular Maintenance to Keep the Surface Smooth

Once your tarmac driveway is installed, regular maintenance will help to preserve its smooth, professional finish. Maintaining your tarmac driveway will ensure that it remains attractive and durable for years to come.

Tips for Maintenance:

• Regular cleaning: Sweep your driveway regularly to remove dirt, leaves, and debris that could cause the surface to wear prematurely.
  
• Sealant application: Consider applying a sealant to your tarmac driveway every few years. This will help protect it from stains and weathering, and maintain its smooth appearance.
  
• Repairs: If any cracks or damage occur, address them promptly to prevent further deterioration. Tarmac is easy to repair, so quick action can prevent costly repairs in the future.
