#4 Stone (2.5″)

#4 Stone in a 2.5” Size Range

#4 stone in a 2.5" size range is a large, crushed aggregate commonly produced from durable materials such as granite, limestone, or gravel. The stones are mechanically crushed and screened to ensure a consistent size, making them ideal for heavy-duty construction applications.




The larger 2.5" size of #4 stone provides excellent drainage and load-bearing capabilities, making it particularly effective as a base material for roadways, driveways, and parking lots. Its substantial size prevents compaction, allowing water to flow freely through the aggregate, which helps reduce erosion and manage stormwater runoff. This makes #4 stone a preferred choice for erosion control, septic system drainage fields, and as a stabilizing layer beneath concrete slabs or retaining walls. While its size offers superior drainage, it is not suitable for areas requiring a smooth or compacted surface, and may not be ideal for decorative landscaping due to its coarse appearance.
