Proper grading is the backbone of any successful asphalt or bitumen surfacing project. When it’s not done right, the consequences can be both inconvenient and expensive. At Kenilworth Asphalt & Bitumen Surfacing, we’ve seen first-hand how small oversights in groundwork can lead to major failures down the track. Whether you’re dealing with driveways, car parks, or rural roads, understanding the risks of poor grading is crucial to protecting your investment.
The Role of Grading in Surface Longevity
Grading isn’t just about shaping the land. It’s about creating a stable, even base that encourages proper drainage and supports the layers of surfacing above. Without a well-executed grading plan, water can quickly become your biggest enemy.
Why Drainage Is Everything
Water that isn’t guided away from the surface will:
- Pool in low areas, softening the sub-base
- Lead to potholes, rutting, and cracking
- Accelerate surface erosion
- Undermine the strength of your asphalt or bitumen seal
These issues are especially common in high-traffic or heavy-load areas, where excess moisture rapidly compounds surface damage.
The Financial Fallout of Poor Grading
When grading isn’t handled correctly at the start, the consequences become expensive fast. You could be facing:
- Premature resurfacing or total reconstruction
- Repeated patch repairs that add up over time
- Loss of functionality for driveways or hardstands
- Safety hazards and liability risks due to uneven or failing surfaces
In many cases, these problems could have been entirely avoided with correct levelling and water runoff design during the initial groundwork.
Early Signs of Grading Problems
Spotting issues early can help you intervene before the damage worsens. Watch out for:
- Water pooling or slow drainage after rain
- Uneven wear or settlement in specific areas
- Cracking along edges or in wheel paths
- Localised soft spots when walking or driving over the surface
These are all indicators that the sub-base may not have been correctly prepared—or that ground movement is exposing underlying weaknesses.

Investing in Quality from the Ground Up
