What Causes Cracking in Tarmac and How to Stop It Early

Understanding Why Tarmac Cracks

Tarmac is one of the most popular driveway materials in the UK thanks to its durability and smooth finish. However, like any surface, it can develop cracks over time if not properly maintained. Knowing what causes these cracks can help homeowners in Haddenham take preventative action and keep their driveway looking its best. Haddenham Driveways has extensive experience in diagnosing and treating tarmac issues early to prevent them from becoming expensive problems later.

The Main Causes of Tarmac Cracking

Weather Extremes

Tarmac naturally expands and contracts with temperature changes. Prolonged exposure to freezing conditions, followed by thawing, can lead to small fractures that gradually widen.

Heavy Vehicle Traffic

Driveways that bear the weight of large vehicles can develop surface stress over time. This is particularly common if the base layer beneath the tarmac wasn’t installed correctly or has been compromised.

Water Penetration

Standing water can seep into tiny gaps in the tarmac. When temperatures drop, the water freezes and expands, causing the surface to break apart. Proper drainage is essential to avoid this issue.

Ageing Surface

Like all materials, tarmac will eventually degrade. Over years of use, it may become brittle, making it more susceptible to cracking.

Tree Roots and Ground Movement

Roots from nearby trees and shrubs can push up beneath the driveway, causing unevenness and cracks. Similarly, soil movement can shift the base layer and compromise the surface.

How to Stop Cracks Early

Regular Inspections

Checking your driveway a few times a year allows you to spot small cracks before they grow. Early action can prevent full resurfacing later.

Professional Repairs

Filling and sealing small cracks quickly will stop water from getting in and causing further damage. Haddenham Driveways uses professional-grade materials to ensure repairs last.

Sealcoating

Applying a protective seal to the tarmac every few years can extend its life and protect it from weathering and chemical spills.

Improving Drainage

Ensuring proper water run-off reduces standing water and helps prevent frost-related damage.

Cracks in tarmac driveways are common but preventable if you act early. Regular inspections, timely repairs, and protective maintenance can dramatically increase the life of your driveway and keep it looking new.
