#4 Limestone is a large, versatile crushed aggregate that provides excellent drainage and structural support. Smaller than #2 Limestone, it typically passes through a sieve with apertures ranging from 1½″ to 2½″ in diameter. This size makes it ideal for a wide range of applications, including base material for roads and driveways, construction fill, culverts, ditches, drainage systems, and erosion control.

Its durability and strength make it a popular choice for projects requiring stability, load-bearing capacity, and reliable water flow, both in construction and landscaping.
