Crushed Stone Calculator Guide
Types of Crushed Stone
Crushed stone comes in various sizes and types, each suited for specific applications. Here are the most common types:
The most versatile and commonly used size. Ideal for driveways, drainage, and as a base for concrete slabs.
Larger stones used for drainage applications, erosion control, and as a base layer for larger projects.
Smaller stones often used for walkways, decorative landscaping, and as a top dressing.
Fine crushed stone used for paver base, leveling material, and as a joint filler between pavers.
Recommended Depths for Different Applications
| Application | Recommended Depth | Stone Type | Notes |
|---|---|---|---|
| Driveways | 4-6 inches (10-15 cm) | #57 Stone | Add 2" of stone dust on top for a smoother finish |
| Walkways | 2-4 inches (5-10 cm) | #8 Stone or Stone Dust | Compact well for stability |
| Drainage Areas | 6-12 inches (15-30 cm) | #1 Stone or #57 Stone | Larger stones allow better water flow |
| Paver Base | 4-6 inches (10-15 cm) | #57 Stone + 1" Stone Dust | Stone dust provides a smooth, level surface |
| Landscaping | 2-3 inches (5-7.5 cm) | #8 Stone or Decorative Stone | Use landscape fabric underneath to prevent weed growth |
Coverage Estimates
Here's a quick reference for how much area one cubic yard of crushed stone will cover at various depths:
Note: These are approximate values. Actual coverage may vary based on compaction and stone type.
Installation Tips
- Prepare the Base:
Remove all vegetation, topsoil, and debris from the area. Grade the soil to ensure proper drainage away from structures.
- Use Landscape Fabric:
Install landscape fabric to prevent weed growth and keep the stone from mixing with the soil below.
- Proper Compaction:
Use a plate compactor or roller to compact the stone, especially for driveways and walkways. This increases stability and reduces settling.
- Edging:
Install edging to contain the crushed stone and prevent it from spreading into surrounding areas.
