Introduction
Potholes are a recurring headache for property owners, councils, and facility managers alike. While temporary patching may seem like a quick fix, it often leads to frustration when the same holes reappear after rain, traffic, or seasonal changes. At Hurstbridge Road Tech, we understand the unique conditions in Hurstbridge and why potholes persist — but more importantly, we know how to fix them properly the first time. This blog explores the reasons behind recurring potholes and the solutions that ensure long-lasting results.
Why Do Potholes Keep Coming Back?
1. Poor Base Conditions
Most pothole problems start below the surface. When the sub-base (the layer beneath the asphalt) is not adequately compacted or becomes saturated with water, it loses strength.
- Water weakens the base and leads to collapse
- Insufficient compaction causes movement under traffic
- Thin or unbound layers fail under repeated stress
Without addressing the base, even the best surface repair will eventually give way.
2. Temporary Patch Methods
Cold mix asphalt is often used for quick pothole patches, but it’s not a long-term solution.
- Lacks bonding strength to existing surface
- Breaks apart under repeated loading
- Susceptible to water infiltration and erosion
These “band-aid” fixes offer short-term relief but do not solve the underlying structural problem.
3. Inadequate Drainage
Water is one of the leading causes of pothole recurrence. Without proper drainage, surface and sub-surface water accumulates, undermining the structure.
- Pooling around potholes accelerates surface degradation
- Water seeps through cracks, softening the base
- Frost and temperature changes can worsen cracking and heaving
Drainage design and management are key to long-term surface performance.
4. Low-Quality Materials or Workmanship
Not all asphalt or patching materials are created equal. Using substandard products or cutting corners during repair leads to early failure.
- Incorrect mix designs lead to poor compaction
- Unsealed edges allow moisture entry
- Lack of proper equipment results in uneven patches
Proper repair requires professional-grade materials and methods tailored to local traffic and weather conditions.
How to Fix Potholes for Good
1. Identify the Root Cause
A thorough site inspection is essential to determine the actual cause of the pothole — not just treat the symptoms. At Hurstbridge Road Tech, we assess:
- Base condition and compaction levels
- Drainage performance around the area
- Type and volume of traffic on the surface
- Surrounding surface condition and cracking patterns
This diagnostic approach ensures repairs target the problem at its source.
2. Rebuild the Base if Needed
If the base is compromised, the damaged section must be excavated and rebuilt.
- Remove loose or unstable material
- Replace with compacted aggregate or stabilised layers
- Ensure moisture is controlled before resurfacing
A strong base supports the surface and prevents future failures.
3. Use Hot Mix Asphalt and Proper Sealing
For long-lasting repairs, we use hot mix asphalt and ensure edges are sealed to protect against water infiltration.
- Compacted to industry specifications
- Finished flush with surrounding surface
- Bonded and sealed to prevent lifting or cracking
This creates a seamless repair that blends into the existing pavement and resists further breakdown.
4. Improve Drainage and Preventative Maintenance
Even the best surface won’t last without good drainage and regular upkeep.
- Grade surrounding areas to encourage runoff
- Install edge drains or swales where needed
- Schedule regular inspections and crack sealing
Proactive maintenance can extend surface life and reduce the need for repeated patching.
Conclusion
Potholes that keep coming back are not just a surface-level problem — they’re a sign of deeper structural or environmental issues. Quick patches might buy some time, but real, lasting solutions come from understanding and addressing the cause.
