For any industrial or commercial site, a hardstand is a vital piece of infrastructure. These surfaces must handle heavy vehicles, constant traffic, and varying weather conditions. Yet one of the most overlooked elements in extending the life of a hardstand is correct grading. At Springbrook Asphalt & Bitumen Surfacing, we understand that proper grading in Springbrook, QLD plays a critical role in preventing potholes and maintaining long-term surface performance.
What Is Grading and Why Does It Matter?
Grading refers to the shaping and levelling of a surface to control how water flows across it. In hardstand construction, grading ensures that rainwater drains away from the surface efficiently rather than pooling in low areas. Poor drainage is one of the primary causes of potholes, as water seeps into the layers below and weakens the structure over time.
The Link Between Grading and Potholes
When grading is not done correctly, standing water can penetrate cracks and joints in the asphalt or bitumen surface. This water can:
- Erode the base layers
- Cause freeze-thaw cycles in colder regions
- Lead to material separation and cracking
- Increase the chances of surface breakdown
The result is the formation of potholes—small at first, but growing rapidly with traffic and time.
Signs Your Hardstand May Be Poorly Graded
If you’re unsure whether your hardstand has the proper slope and drainage, look for these warning signs:
- Pooling water after rain
- Damp or soft spots along vehicle paths
- Early signs of surface cracking or rutting
- Uneven wear in high-traffic areas
- Moss or algae growth near low points
Any of these may indicate insufficient grading and could lead to costly surface deterioration if left unaddressed.
Key Elements of Proper Grading
At Springbrook Asphalt & Bitumen Surfacing, we apply strict grading practices to ensure long-term durability for hardstands. Effective grading includes:
- Correct slope angles – Typically a minimum of 1–2% fall for water to flow away
- Crossfall or crown shaping – Directs water to the sides
- Edge drainage installation – Channels excess water to designated run-offs
- Compact and stable subgrade – Prevents shifting and uneven settling
These steps work together to safeguard the integrity of the hardstand and reduce the likelihood of potholes developing.
Long-Term Benefits of Well-Graded Hardstands
Investing in proper grading during installation or resurfacing offers several long-term advantages:
- Reduces maintenance costs by avoiding premature repairs
- Improves safety by reducing standing water and associated hazards
- Extends lifespan of the asphalt or bitumen surface
- Enhances structural performance under heavy loads
- Boosts site appearance and functionality
For industrial and commercial facilities in Springbrook, these benefits translate into smoother operations, fewer disruptions, and a higher return on investment.
Ongoing Maintenance to Support Proper Grading
Even with perfect grading at installation, regular upkeep is essential. Over time, heavy traffic, settlement, and erosion can alter the slope or drainage pattern. To maintain optimal grading, it’s important to:
- Inspect for water pooling after heavy rain
- Keep surface drains and run-offs clear
- Regrade or patch areas where rutting has occurred
- Apply sealant or resurfacing when cracks appear
Routine inspections from professionals like the team at Springbrook Asphalt & Bitumen Surfacing can help catch issues early and avoid larger problems.
