#4 Stone (3/4″ To 1.5″, Ballast)

#4 Stone Ballast in a 3/4” to 1.5” Size Range

#4 stone ballast in a 3/4” to 1.5” size range is a coarse aggregate commonly produced by crushing and screening durable rock such as granite, limestone, or gravel. The “ballast” attribute indicates that this material is specifically selected for its stability and load-bearing properties, making it ideal for foundational and support applications.

The larger size range of 3/4” to 1.5” allows for excellent drainage and prevents compaction, which is crucial in applications where water needs to flow freely, such as under railroad tracks, retaining walls, and drainage systems. This size also provides substantial weight and interlocking capability, enhancing stability for heavy-duty projects. #4 stone ballast is frequently used in commercial and residential settings for railroad ballast, base layers for driveways and roads, erosion control, and as a foundation for large-scale construction projects.

Pros of this material include superior drainage, resistance to shifting, and long-term durability. However, its coarse texture and large size make it unsuitable for areas requiring a smooth or compacted surface. Overall, #4 stone ballast is a reliable choice for structural support and drainage-critical applications.
