Cracks in asphalt or bitumen surfaces are more than just cosmetic flaws—they’re early warning signs of underlying problems. At Goondiwindi Asphalt & Bitumen Surfacing, we regularly help property owners across Goondiwindi, QLD identify and address surface issues before they escalate into costly damage.
Understanding what different types of cracks mean can help you act early, protect your investment, and maintain a safe and functional surface.
Why Surface Cracks Should Never Be Ignored
Even a small crack can quickly turn into a major issue if left untreated. Moisture, debris, and temperature fluctuations can widen the damage, leading to potholes, base failures, and structural instability.
Risks of ignoring cracks:
- Water infiltration undermining the base
- Accelerated surface deterioration
- Safety hazards for pedestrians and vehicles
- More costly repairs down the line
Whether it’s a driveway, access road, or car park, early detection and repair are essential for maintaining the longevity of your surface.
Common Crack Types and What They Might Indicate
Each crack pattern tells a story about the condition of the surface and sub-base. Recognising these signs can help you determine the right response.
1. Hairline Cracks
- Often caused by normal ageing or surface shrinkage
- Typically shallow, but can worsen with UV exposure and water ingress
- Early sealing can prevent escalation
2. Longitudinal Cracks
- Run parallel to the direction of traffic
- May result from poor joint construction or underlying movement
- Suggests potential base instability or thermal expansion
3. Transverse Cracks
- Run perpendicular to traffic flow
- Usually linked to temperature fluctuations and asphalt brittleness
- Should be sealed quickly to prevent water penetration
4. Block Cracking
- Forms large square or rectangular patterns
- Often due to aged, dry bitumen or inadequate bonding between layers
- Indicates the surface is losing flexibility
5. Alligator Cracking
- Resembles a reptile’s skin with interconnected cracks
- Signals severe structural failure in the base or sub-base
- Requires more than surface patching—likely full-depth repair
Contributing Factors to Asphalt and Bitumen Cracking
Surface cracks can be caused by a combination of factors. Identifying these helps prevent recurrence after repair.
Environmental and site factors:
- UV exposure and oxidisation
- Repeated traffic loading
- Inadequate drainage
- Poor compaction during installation
- Ageing of the surface material
At Goondiwindi Asphalt & Bitumen Surfacing, we inspect all contributing conditions to recommend lasting solutions—not just short-term fixes.
What You Should Do If You Spot a Crack
Cracks are easier and cheaper to fix when addressed early. Waiting until they widen or multiply can lead to base failure and require complete resurfacing.
Steps to take:
- Inspect your surface regularly, especially after seasonal changes
- Note crack type, size, and pattern
- Contact a professional to assess and recommend treatment
- Avoid temporary DIY fillers—they often fail under traffic or weather
Goondiwindi Asphalt & Bitumen Surfacing offers tailored solutions, including crack sealing, patching, and resurfacing as required.
Conclusion: Small Cracks Can Signal Big Problems
Cracks in your driveway or road surface might seem minor, but they can be early indicators of deeper issues. Ignoring them risks structural deterioration and higher long-term costs. Whether it’s hairline fractures or alligator cracking, acting early is always the best approach.
