Gravel driveways are common on lifestyle blocks. They are affordable and practical, but they need regular maintenance to stay usable — especially on hill properties or after heavy rain.
Routine maintenance
- **Re-grade the surface** once or twice a year to restore the crown (the slight centre camber that sheds water). A tractor with a grading blade or a contractor with a skid-steer can do this.
- **Fill potholes** promptly with matching gravel. Do not just fill with soil — it turns to mud in winter.
- **Keep culverts and side drains clear** so water does not pond on or beside the drive.
- **Top up metal** as needed. AP65 or similar crushed aggregate is common for rural drives.
Drainage is key
Most driveway problems are drainage problems. If water ponds on the surface, runs down the middle, or undercuts the edge, the gravel will shift and pothole. Make sure:
- The surface has a crown so water sheds to both sides
- Side drains are clear and deep enough to carry runoff
- Culverts under the drive are not blocked
When to call a contractor
- The driveway needs regrading and you do not have the machinery
- Potholes keep returning despite filling (usually a drainage issue)
- You need a new culvert or the existing one has collapsed
- You want to widen, extend, or resurface the drive
- Runoff from the drive is causing erosion on the property
Questions to ask an earthworks contractor
- What machinery do you use for driveway grading?
- Can you supply and lay gravel, or do I need to source it?
- Can you install or replace culverts?
- What is your minimum charge-out or mobilisation fee?
- Do you handle drainage as well as surfacing?
