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:

🪨
#57 Stone (3/4" to 1")

The most versatile and commonly used size. Ideal for driveways, drainage, and as a base for concrete slabs.

🪨
#1 Stone (2" to 4")

Larger stones used for drainage applications, erosion control, and as a base layer for larger projects.

🪨
#8 Stone (3/8")

Smaller stones often used for walkways, decorative landscaping, and as a top dressing.

🪨
Stone Dust

Fine crushed stone used for paver base, leveling material, and as a joint filler between pavers.

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.
