#57 Stone (Medium, Slate)

#57 Stone - Medium Slate Aggregate

#57 stone in a medium size range, composed of slate, is a versatile construction aggregate prized for its durability and unique mineral composition. Produced by crushing and screening slate rock, this material features angular particles that interlock well, providing stability in a variety of applications.

The medium size of #57 stone-typically around 3/4”-offers an ideal balance between drainage and compaction. The slate attribute enhances its resistance to weathering and adds a distinctive appearance, making it suitable for both functional and decorative uses. Common applications include driveways, drainage systems, walkways, and as a base material for patios or retaining walls. Its angular shape ensures good load-bearing capacity and prevents shifting, while the slate composition may offer a more attractive finish compared to standard gravel. However, slate can be more brittle than some other stone types, so it may not be ideal for high-impact areas. Overall, this aggregate is a reliable choice for projects requiring both performance and visual appeal.
