Spray & Seal bitumen surfacing is a practical and cost-effective solution widely used across Victoria for driveways, hardstands, car parks, and rural roads. While it’s a durable surface choice, like any infrastructure investment, proper maintenance is key to ensuring longevity and performance.
At Wattle Glen Road Tech, we provide asphalt and bitumen surfacing services throughout Wattle Glen, VIC. In this guide, we share essential maintenance tips to help property owners, developers, and facility managers protect their Spray & Seal surfaces year after year.
Understand the Nature of Spray & Seal
Spray & Seal consists of a sprayed bitumen layer covered with aggregate. Over time, this surface can wear due to traffic loads, water, sunlight, and seasonal temperature changes. Proactive maintenance helps prevent early degradation and keeps the surface functional and presentable.
Regular Surface Inspections
Routine checks help detect issues before they develop into major defects.
- Inspect quarterly, especially after heavy rainfall or hot spells
- Look for signs of aggregate loss, bitumen exposure, or surface cracking
- Identify early rutting, ponding, or soft spots under pressure
Timely intervention can extend the life of the surface and reduce repair costs.
Prompt Pothole and Crack Repairs
Bitumen surfaces can crack or break under pressure or moisture ingress. These minor issues can become major problems if ignored.
- Seal cracks with appropriate bitumen crack filler
- Patch potholes as soon as they appear
- Ensure all repairs are level and compacted properly
Early repair prevents water from undermining the structure beneath.
Clean the Surface Periodically
Dirt, organic debris, and loose aggregate can degrade bitumen over time.
- Sweep or blow off leaves, dirt, and sediment every few months
- Remove standing water or moss build-up in shaded areas
- Avoid letting oil or chemical spills sit uncleaned
A clean surface preserves its grip and prevents premature ageing.
Monitor Edge Integrity
Edges of Spray & Seal surfaces are more vulnerable to wear and damage from vehicle movement or water runoff.
- Check for crumbling or displaced aggregate along the shoulders
- Reinforce weakened edges with additional bitumen and stone
- Ensure surface water drains away from the edges correctly
Maintaining the edge structure helps avoid full-width failures.
Rejuvenation Spray Every Few Years
A rejuvenation spray is a light application of bitumen that helps reseal and refresh the surface.
- Typically applied every 5–7 years depending on traffic levels
- Restores surface waterproofing and adhesive strength
- Helps rebond any loose aggregate
This is a cost-effective way to extend the lifespan of a Spray & Seal installation.
Manage Heavy Vehicle Loads
Although Spray & Seal is suitable for moderate traffic, constant heavy vehicle use can accelerate wear.
- Limit access for vehicles over the design load
- Use load-distributing mats or reinforce high-use areas
- Consider dual-coat systems for high-pressure zones
At Wattle Glen Road Tech, we assess each project to recommend the correct surface strength based on expected traffic.
Keep Drainage Functioning
Poor drainage accelerates surface breakdown by allowing water to enter the structure.
- Clean out nearby gutters, swales, and drains regularly
- Reshape grading if water tends to pool on the surface
- Inspect after storms for signs of water damage or washouts
Proper drainage helps keep the base layer intact and the surface stable.
