#1 Stone (1.5″ To 3.5″, Crushed)

#1 Crushed Stone (1.5” to 3.5”)

#1 crushed stone in a 1.5” to 3.5” size range is a large, angular aggregate produced by mechanically crushing quarried rock. The crushed attribute means each stone has sharp, irregular edges, which help the material lock together for enhanced stability in heavy-duty applications.

This larger size is ideal for projects requiring substantial load-bearing capacity and excellent drainage. Common uses include base layers for road construction, erosion control, septic system drainage fields, and as a foundation for retaining walls. The angular shape prevents shifting and settling, making it a reliable choice for structural support. However, due to its size, #1 crushed stone is not suitable for compacted surfaces like driveways or walkways, as it can be difficult to walk on and does not create a smooth finish.

Overall, #1 crushed stone is valued for its strength, durability, and superior drainage properties, making it a preferred option for demanding commercial and residential construction projects.
