Aggregate Base Course (2.5″, Ballast)

Aggregate Base Course Ballast in a 2.5” Size Range

Aggregate Base Course ballast in a 2.5" size range is a coarse, durable construction material composed of crushed stone or gravel. This material is produced by mechanically crushing and screening quarried rock to achieve a consistent, angular particle size. The "ballast" attribute indicates that the aggregate is specifically selected for its strength and stability, making it ideal for heavy-duty foundational applications.




The 2.5" size range provides excellent load-bearing capacity and superior drainage, which is essential for projects requiring a stable base that resists shifting and settling. This makes it a preferred choice for railway track beds, road sub-bases, and large-scale commercial or industrial foundations. In residential settings, it is often used beneath driveways, parking areas, and retaining walls where robust support is needed. While its large, angular particles offer outstanding stability and drainage, they can be difficult to compact tightly, so a finer top layer is often recommended for finished surfaces.
