The Truth About Tarmac Cracking & How to Prevent It
Tarmac remains one of the most popular surfacing choices for driveways, paths, and commercial areas across the UK. Its durability, clean appearance, and long-lasting performance make it a reliable option for homeowners. However, like all outdoor surfaces, tarmac is not completely immune to wear. One issue that occasionally concerns property owners is cracking. Understanding why cracking occurs—and how to prevent it—helps protect the longevity and appearance of your driveway. Rothwell Driveways & Patios supports homeowners throughout Rothwell, Northamptonshire with professional installations designed to minimise these issues and maximise durability.
Why Tarmac Cracks: The Real Causes
Cracking does not happen for no reason. It is a surface response to specific conditions, many of which can be avoided with the right installation and maintenance approach.
Natural Ageing and Weather Exposure
Tarmac, like any outdoor material, ages over time. Repeated exposure to sun, frost, rain, and temperature fluctuations causes gradual changes in the surface.
- Heat can soften tarmac, making it more flexible
- Cold temperatures cause contraction, which can create small fissures
- Frost and ice may worsen weaknesses already present
These natural changes can lead to surface cracks, especially on older driveways that have had little maintenance.
Sub-base Movement or Weak Foundations
One of the biggest causes of tarmac cracking is not the tarmac itself, but the ground beneath it. A poorly prepared sub-base may shift, settle, or erode, putting pressure on the surface layer.
If the foundations are not compacted properly, the tarmac will eventually crack due to uneven support. Rothwell Driveways & Patios ensures all installations in Rothwell, Northamptonshire start with a strong, stable foundation to prevent this issue.
Excessive Weight or Heavy Use
While tarmac is extremely durable, it does have limits. Constant heavy vehicle use, sharp turning, or parking in the same spot for long periods can place strain on certain sections.
Over time, this can lead to:
- Indentations
- Pressure cracks
- Weak or worn patches
Correct installation and thickness of the surface layer help prevent these problems.
Water Damage and Poor Drainage
Standing water is a common cause of early tarmac deterioration. If rainwater sits on the surface rather than running away, it can:
- Cool the tarmac unevenly
- Soften weakened areas
- Penetrate small cracks and expand them during frost
Good drainage is essential for longevity, and Rothwell Driveways & Patios designs driveways to prevent water pooling.
How to Prevent Tarmac Cracking
While some cracking comes with natural ageing, professional installation and regular care dramatically reduce the likelihood of problems. With the right approach, your driveway can remain smooth and resilient for many years.
Choose a High-Quality Installation
The most effective way to prevent cracking is to ensure the driveway is professionally installed. This includes:
- A properly prepared sub-base
- Correct compaction
- High-quality tarmac materials
- Suitable depth for expected usage
- Expert finishing
Rothwell Driveways & Patios follows industry best practices on every installation in Rothwell, Northamptonshire to ensure a durable and long-lasting surface.
Maintain Good Drainage
Ensuring rainwater flows away from the driveway is essential in preventing water-related cracking. Homeowners can support good drainage by:
- Keeping gullies and channels clear
- Ensuring soil and borders do not block edges
- Checking that water is not pooling anywhere on the surface
Professional installation will naturally incorporate correct drainage slopes, but good upkeep plays a role too.
Avoid Parking Heavy Vehicles in One Spot
Consistently applying pressure to one part of the driveway can weaken the surface over time. Where possible, vary parking position slightly to distribute weight evenly.
Treat Minor Damage Early
Small imperfections can spread if ignored. Early intervention helps prevent bigger cracks from forming. Homeowners should look for:
- Tiny surface cracks
- Slight dips or soft patches
- Areas where water collects during rain
If you spot early warning signs, Rothwell Driveways & Patios can assess and repair the affected area before it worsens.
