Limestone
#4 Limestone is medium versatile and commonly used aggregate. It is smaller than #2 Limestone, passing through a sieve with apertures typically ranging from 1 1/2″ - 2 1/2″ in diameter. This size makes it ideal for a variety of applications, including base material, construction fill, drainage, and areas where intermediate aggregate sizes are needed for structural integrity and stability. Its durability and strength make it a popular choice in many construction and landscaping projects.
