Types of Gravel
There is a wide range of gravel types to consider. Here are some of the most common ones:
- Pea Gravel: Known for its small, round stones, pea gravel is often used for its aesthetic appeal. However, it may not be the best choice for a driveway due to its tendency to move around.
- Crushed Stone: This is a popular option for driveways as it compacts well and provides a stable surface. Crushed stone comes in various sizes, from fine dust to larger, jagged pieces.
- Jersey Shore Gravel: This type of gravel is also smooth and round, often found in shades of yellow, tan, and white. Like pea gravel, it’s more decorative and less practical for driveways.
- Quarry Process (QP): A mix of stone dust and crushed stone, QP is excellent for creating a stable base layer on your driveway.
Gravel Size
Size matters when it comes to driveway gravel. The gravel size you choose will impact drainage, stability, and the overall look of your driveway. Here are some common sizes:

- 3/4-inch Gravel: This size is excellent for a supportive base layer. It’s large enough to provide good drainage yet small enough to compact well.
- 1/2-inch Gravel: Slightly smaller, this size is often used as a top layer. It offers a smoother surface but still provides adequate drainage.
- Pea Gravel: Usually 3/8-inch in diameter, pea gravel is more decorative and less functional for load-bearing surfaces.
Choosing the correct type gravel and gravel size will set the foundation for a durable and attractive gravel driveway.
Installing Gravel: Steps and Considerations
Installing a gravel driveway involves more than just pouring stones onto the ground. Proper installation ensures longevity and reduces the need for frequent maintenance.
Site Preparation
Before you start installing gravel, proper site preparation is critical:
- Mark the Area: Use stakes and string to outline the driveway size.
- Excavate: Remove the topsoil to a depth of at least 8-12 inches. This creates a stable base and helps prevent weed growth.
- Install a Weed Barrier: Lay down a geotextile fabric to prevent weeds from growing through the gravel.
Building the Base Layer
The base layer is crucial for stability and drainage:
- Add a Sub-base: Use large stones or crushed stone to create a sub-base layer of about 4-6 inches.
- Compact the Sub-base: Use a compactor to ensure the sub-base is stable and firm.
- Add a Middle Layer: Add a 2-3 inch layer of smaller, crushed stones. Compact this layer as well.
Adding the Top Layer
The top layer completes the driveway:
- Choose the Top Layer Gravel: Select your desired type and size of gravel for the top layer.
- Spread Evenly: Spread the gravel evenly, ensuring a uniform thickness.
- Compact the Gravel: Use a compactor to press the gravel firmly into place.
Proper installation from the ground up ensures a long-lasting, low-maintenance gravel driveway.
Maintaining Your Gravel Driveway
Maintaining a gravel driveway requires regular attention but isn’t overly complicated. Routine maintenance can extend the life of your driveway and keep it looking its best.
Addressing Weed Growth
Weed growth can be a common issue in gravel driveways. Here are some ways to manage it:
- Use a Weed Barrier: If you didn’t install one initially, consider adding a geotextile fabric beneath the gravel.
- Herbicides: Use environmentally friendly herbicides to kill any existing weeds.
- Manual Removal: Regularly inspect your driveway and pull out any weeds by hand.
Managing Gravel Displacement
Gravel tends to migrate over time, especially in areas with heavy traffic:
- Rake Regularly: Use a rake to distribute gravel evenly across the driveway.
- Add More Gravel: Periodically add more gravel to areas that seem to be thinning out.
- Gravel Stabilisation: Consider using gravel stabilisation grids to keep gravel in place.
Erosion Control
Rain and water runoff can erode your gravel driveway:
- Install a Drainage System: Ensure proper drainage by installing French drains or ditches along the sides of the driveway.
- Create a Crown: Shape your driveway so that it’s higher in the middle, allowing water to run off to the sides.
Regular Compaction
Over time, gravel can loosen and become uneven:
- Compact Regularly: Use a compactor to press the gravel back into place.
- Fill Potholes: Add gravel to any potholes or low spots and compact it thoroughly.
Regular maintenance practices will keep your gravel driveway in optimal condition, ensuring it remains functional and attractive.
