How to Repair Worn or Patchy Tar & Chip Surfaces

Tar and chip surfaces are a cost-effective and durable option for driveways and roads. However, over time, wear and weather conditions can cause patchy areas, loose stones, and surface deterioration. Proper maintenance and timely repairs can extend the lifespan of your tar and chip driveway, keeping it in excellent condition. This guide will explore effective repair methods to restore your surface and ensure long-term durability.

Signs That Your Tar & Chip Surface Needs Repair

Loose or Missing Stones

Over time, traffic and weather can dislodge the top layer of stones, leaving bare patches that reduce the driveway’s visual appeal and grip.

Cracking and Potholes

Cracks and potholes can form due to freeze-thaw cycles, excessive use, or poor drainage. These issues can worsen if left untreated.

Uneven Surface Appearance

If certain sections of your driveway appear patchy or worn while others remain intact, it may be time for a fresh layer of tar and chip.

Steps to Repair a Worn or Patchy Tar & Chip Driveway

Cleaning and Preparing the Surface

Before carrying out any repairs, it is essential to prepare the area properly:

• Remove debris and loose stones using a stiff broom or power washer.
• Ensure the surface is dry to allow proper adhesion of new materials.
• Fill cracks or potholes with an appropriate patching compound to create a smooth base.

Reapplying Tar and Chip to Patchy Areas

If small sections of your driveway are worn out but the overall structure is sound, a simple reapplication of tar and chip can restore the surface:

1. Apply a fresh layer of bitumen (tar) over the affected area.
2. Spread new stone chips evenly across the surface.
3. Compact the stones using a roller to ensure they adhere properly.
4. Allow the surface to settle for a few days before driving over it.

Full Re-Sealing for Extensive Wear

If the entire surface has become patchy and worn, a full re-seal may be required:

• Spray a new layer of hot bitumen across the entire driveway.
• Evenly distribute fresh aggregate stones for a consistent finish.
• Compact the surface to ensure longevity and durability.

This process restores the original appearance and provides a long-lasting protective layer.

Preventative Maintenance Tips

Regular Sweeping and Cleaning

Keeping the surface free from debris and loose stones can prevent premature wear and maintain its aesthetic appeal.

Addressing Drainage Issues

Poor drainage can weaken the surface over time. Ensure that water runoff is directed away from the driveway to prevent pooling and erosion.

Periodic Re-Sealing

Re-sealing the surface every 5–7 years can extend the lifespan of a tar and chip driveway, keeping it in top condition.
