#67 Stone (#4 To 3/4″, Spec)

#67 Stone, Spec, #4 to 3/4" Size Range

#67 stone in a #4 to 3/4" size range, produced to spec, is a versatile crushed aggregate commonly used in construction and landscaping. Manufactured by mechanically crushing larger rocks, this material is carefully screened to ensure consistent sizing between #4 (approximately 1 inch) and 3/4 inch. The "spec" attribute indicates that the stone meets specific industry standards for gradation and quality, ensuring reliable performance in demanding applications.

The #4 to 3/4" size range offers an ideal balance between drainage and compaction. This makes #67 stone particularly effective for use as a base layer under concrete slabs, driveways, and walkways, as well as for drainage systems, retaining wall backfill, and pipe bedding. Its angular shape helps lock the stones together, providing stability while still allowing water to flow through, reducing the risk of pooling or erosion. While it compacts less tightly than finer aggregates, its excellent drainage properties and load-bearing capacity make it a preferred choice for both residential and commercial projects.
