#4 Stone (1.5″ Minus)

#4 Stone in a 1.5” Minus Size Range

#4 stone in a 1.5” minus size range is a versatile crushed aggregate commonly used in construction and landscaping. This material consists of angular stones that are screened to include pieces up to 1.5 inches in diameter, along with smaller particles and fines. The “minus” designation means the mix contains a range of sizes from the maximum down to dust, which helps the material compact well and lock together for stability.

The 1.5” minus size makes #4 stone ideal for applications where both drainage and compaction are important. It is frequently used as a base layer for driveways, parking lots, and roadways, as well as for erosion control and backfilling retaining walls. The blend of larger stones and fines provides excellent load-bearing capacity while minimizing voids, making it less prone to shifting under heavy use. However, the presence of fines means it may not drain as freely as clean, washed stone, so it is best suited for structural support rather than high-drainage applications.
