Angular gravel has become a popular choice for landscaping projects due to its superior interlocking properties and aesthetic appeal. Unlike rounded gravel, which can shift and create unstable surfaces, angular gravel provides a more secure and durable option for driveways, paths, and decorative features. This guide will walk you through the process of selecting, installing, and maintaining angular gravel, ensuring a successful project for both homeowners and tradespeople.

Understanding Angular Gravel

What is Angular Gravel?

Angular gravel is composed of sharp-edged stones that have been broken or crushed, giving them a jagged appearance. This shape allows the stones to fit together tightly, creating a stable surface that resists movement and erosion. Common types of angular gravel include granite, limestone, and basalt, each offering unique colours and textures.

Benefits of Angular Gravel

• Stability: The interlocking nature of angular gravel provides a firm surface, ideal for driveways and paths.
• Drainage: The gaps between the stones allow for effective drainage, reducing puddles and erosion.
• Aesthetic Variety: Available in various colours and sizes, angular gravel can enhance the visual appeal of any landscape.
• Low Maintenance: Once installed, angular gravel requires minimal upkeep compared to other materials.

Tools and Materials Required

Tools

• Wheelbarrow
• Shovel
• Rake
• Landscape fabric
• Compactor or plate compactor
• Edging material (optional)
• Gloves and safety goggles

Materials

• Angular gravel (choose the type and size based on your project)
• Landscape fabric (to prevent weed growth)
• Edging material (wood, metal, or plastic, if desired)

Steps for Installing Angular Gravel

Step 1: Planning and Preparation

1. Choose the Location: Decide where you want to install the gravel. Consider factors like drainage and accessibility.

2. Measure the Area: Use a measuring tape to determine the dimensions of the area to be covered.

3. Calculate Gravel Needed: Multiply the length, width, and desired depth (usually 5-10 cm) to estimate the volume of gravel required.

Step 2: Preparing the Site

1. Clear the Area: Remove any existing grass, weeds, or debris from the site.

2. Excavate: Dig down to the desired depth, ensuring the base is level and compacted.

3. Install Landscape Fabric: Lay down landscape fabric to prevent weed growth and allow for drainage.

Step 3: Installing the Gravel

1. Add the Gravel: Using a wheelbarrow, transport the angular gravel to the site and spread it evenly.

2. Level the Surface: Use a rake to level the gravel, ensuring an even distribution.

3. Compact the Gravel: Use a compactor to compress the gravel, enhancing stability and preventing shifting.

Step 4: Edging (Optional)

1. Choose Edging Material: Select an edging material that complements your landscape.

2. Install Edging: Place the edging around the perimeter of the gravel area to contain the stones and prevent them from spreading.

Safety Considerations

• Always wear gloves and safety goggles when handling gravel to protect against sharp edges and dust.
• Ensure the area is clear of hazards, such as uneven ground or hidden debris, before starting work.
• If using a compactor, follow the manufacturer's instructions and be cautious of moving parts.

Troubleshooting Common Issues

Uneven Surface

• Cause: Insufficient compaction or uneven gravel distribution.
• Solution: Re-level the gravel and re-compact the area to ensure an even surface.

Weeds Growing Through Gravel

• Cause: Landscape fabric may not be installed correctly or has degraded.
• Solution: Check the fabric for tears and replace if necessary. Regularly remove any visible weeds.
