#4 Stone (1.5″, Limestone)

#4 Limestone Stone in a 1.5” Size Range

#4 stone in a 1.5” size range is a crushed limestone aggregate, produced by mechanically breaking down larger limestone rocks into uniform, angular pieces. This material is known for its durability, strength, and excellent load-bearing properties, making it a reliable choice for a variety of construction and landscaping projects.

The 1.5” size offers superior drainage compared to smaller aggregates, as the larger, angular particles create ample void space for water to flow through. This makes #4 limestone ideal for use in drainage systems, septic leach fields, erosion control, and as a base layer beneath driveways, roads, and heavy-duty parking areas. Its angular shape helps lock the stones together, providing stability while still allowing for effective water movement. While its larger size means it is not suitable for compacted surfaces or decorative top layers, it excels in structural and drainage applications where strength and permeability are priorities.
