Why Do Tarmac Driveways Crack? A Complete Guide to Prevention and Repair

Searching for “how to fix tarmac cracks Bristol” or “driveway crack repair near me”? Before attempting any DIY repairs, understanding why tarmac cracks appear is crucial for implementing the right long-term solution. As experienced “tarmac contractors Bristol”, we’ll explain why these issues occur and why professional intervention is often necessary.

Common Causes of Tarmac Cracking

  • Poor Base Preparation: Without proper sub-base preparation and compaction, the surface lacks adequate support, leading to premature cracking.
  • Water Damage: Inadequate drainage leads to water penetration, which weakens the structure, especially during freeze-thaw cycles.
  • Age-Related Deterioration: UV exposure and weather variations cause natural deterioration over time.
  • Heavy Load Stress: Vehicles exceeding the surface’s weight capacity can cause structural damage.
  • Tree Root Growth: Nearby trees can cause underground movement, leading to surface cracks.
