#67 Stone (#4 To 3/4″, Washed, Astm)

#67 Stone, Washed, ASTM, Size Range: #4 to 3/4"

#67 stone in a washed, ASTM-certified form and a size range from #4 to 3/4" is a versatile crushed aggregate commonly used in construction. Produced by crushing and screening natural rock, this material is then thoroughly washed to remove dust, clay, and other impurities, resulting in a clean, high-quality product that meets ASTM standards for consistency and performance.

The #4 to 3/4" size range offers an ideal balance between compaction and drainage. The washed attribute ensures minimal dust and debris, making it suitable for applications where cleanliness and drainage are critical, such as concrete mixes, drainage systems, and septic fields. It is also frequently used as a base layer for driveways, walkways, and patios, as well as for backfilling and pipe bedding. The main advantages of this material are its excellent drainage properties and reduced risk of compaction issues, though it may not be ideal for areas requiring a tightly packed surface. Its clean, uniform appearance also makes it a popular choice for both residential and commercial projects.
