Aggregate Base Course (1.25″ Minus)

Aggregate Base Course in a 1.25” Minus Size Range

Aggregate Base Course in a 1.25" minus size range is a foundational construction material composed of crushed stone, gravel, or recycled concrete. The "minus" designation means the mix contains particles up to 1.25 inches in diameter, along with smaller fines that fill gaps between larger pieces. This blend creates a dense, stable base that compacts well, making it ideal for supporting structures and surfaces.




The 1.25" minus size is particularly effective for load-bearing applications, as the combination of larger aggregate and fine particles ensures excellent compaction and minimal voids. This results in a strong, stable layer that resists shifting and settling. Common uses include road and driveway sub-bases, parking lots, walkways, and under concrete slabs or pavers. While the fines improve stability, they can also reduce drainage compared to clean or open-graded aggregates. Overall, this material is valued for its strength, versatility, and cost-effectiveness in both residential and commercial projects.
