Aggregate Base Course (1/2″ Minus)

Aggregate Base Course in a 1/2” Minus Size Range

Aggregate Base Course in a 1/2" minus size range is a versatile construction material composed of crushed stone, gravel, or recycled concrete, with particles ranging from 1/2 inch down to fine dust. The "minus" designation means the mix includes both larger aggregate and smaller fines, which fill voids and help the material compact tightly.




This specific size and gradation make it ideal for creating a stable, well-compacted base layer beneath roads, driveways, patios, and walkways. The fines content ensures excellent compaction and load-bearing capacity, reducing the risk of settling or shifting over time. While it offers superior stability and is easy to work with, the presence of fines means it is less permeable than larger, clean aggregates, making it less suitable for drainage applications. Overall, 1/2" minus Aggregate Base Course is a reliable choice for both residential and commercial projects requiring a strong, compacted foundation.
