How to Fix Potholes in Your Tarmac Driveway

Why Potholes Form in Tarmac Driveways

Potholes are a common issue for homeowners, especially after a period of heavy rain or frost. The freeze-thaw cycle is often the main culprit — water seeps into small cracks, freezes, expands, and gradually breaks down the tarmac surface. Over time, the weakened area collapses, leaving behind a hole. At Kempston Driveways & Patios, we regularly help homeowners in Kempston, Bedfordshire restore their tarmac driveways and prevent further damage.

The Importance of Timely Repairs

Leaving a pothole untreated can lead to:

• More extensive cracking as water continues to penetrate the surface
  
• Vehicle damage such as misalignment or tyre wear
  
• Trip hazards that make your driveway unsafe
  
• Costly resurfacing if the damage spreads
  

Acting early ensures that your driveway stays safe, functional, and attractive.

Step-by-Step Guide to Fixing Potholes

While professional repair is the best option for a long-lasting solution, understanding the process helps you know what to expect when Kempston Driveways & Patios carries out your repair.

1. Cleaning the Area

The pothole must first be cleared of dirt, debris, and loose material. This allows the repair material to bond properly to the surrounding tarmac.

2. Cutting and Squaring Edges

To create a neat, strong patch, the edges of the pothole are trimmed to form a clean square or rectangle. This prevents the patch from crumbling prematurely.

3. Applying a Tack Coat

A tack coat is used to improve adhesion between the existing driveway surface and the new tarmac material.

4. Filling with Hot or Cold Lay Tarmac

The pothole is then filled with the appropriate tarmac mix, depending on the size of the repair and the weather conditions.

5. Compacting the Patch

The area is compacted with a roller or vibrating plate to ensure the surface is level and secure, blending with the rest of the driveway.

Preventing Future Potholes

Kempston Driveways & Patios also advises homeowners on preventative maintenance to extend the lifespan of their driveway:

• Regular inspections to catch small cracks early
  
• Sealcoating every few years to protect against water penetration
  
• Keeping drainage clear to prevent standing water from weakening the surface
  
• Avoiding heavy loads that can stress the tarmac
  

Conclusion

Potholes may seem like a minor inconvenience, but if left untreated, they can lead to significant driveway damage. Professional repairs ensure a smooth, durable surface and prevent the need for costly resurfacing later.
