#57 granite, also known as 3/4-inch granite, #57 stone, crushed granite, or clean granite drainage stone, is a clean, angular aggregate commonly used for driveways, drainage, concrete, backfill, landscaping, and general construction. It typically consists of crushed granite ranging from approximately 1/2 inch to 1 inch, with most pieces averaging around 3/4 inch.
Produced at granite quarries and aggregate plants, #57 granite is crushed and screened to remove most stone dust and fine particles, and may also be washed depending on the source and specification. The limited amount of fines leaves open spaces between the stones, allowing water to move freely through the installed layer.
Its fractured, angular shape helps the aggregate settle together and resist movement more effectively than smooth, rounded gravel. Although #57 granite does not compact into a dense, sealed surface, it provides a stable layer capable of supporting vehicle traffic, equipment, concrete, pipes, retaining walls, and other construction features while maintaining drainage.
This combination of drainage and structural support makes #57 granite a practical choice for homeowners, contractors, builders, landscapers, farms, property managers, municipalities, and commercial construction projects. It can be used as driveway stone, drainage aggregate, foundation backfill, pipe bedding, concrete aggregate, or surface material across residential, commercial, agricultural, and infrastructure work.
Because granite is a hard crushed stone, #57 granite is also commonly used in areas exposed to regular vehicle or equipment traffic. Its relatively consistent size makes it easier to spread and place around foundations, utility lines, retaining walls, drainage systems, driveways, parking areas, and other site features.
Compared with crusher run or dense-grade aggregate, #57 granite contains fewer fines and provides better drainage but does not compact as tightly. Crusher run is generally better suited for compacted road bases, driveway foundations, and parking areas, while #57 granite is typically preferred where clean stone, drainage, backfill, concrete aggregate, or open-graded structural support is required.
Exact color, particle shape, and gradation can vary by quarry, supplier, and regional specification. For larger residential, contractor, agricultural, municipal, or commercial projects, #57 granite is commonly available in bulk from local quarries and aggregate suppliers and delivered by dump truck directly to the property or job site.
Common Applications of #57 Granite
- Driveways and residential access roads
- French drains and drainage systems
- Retaining wall and foundation backfill
- Concrete production and aggregate mixes
- Pipe bedding and utility trench support
