1/2″ Clean Limestone Chips also known as #8 limestone, also known as 3/8" clean crushed stone, 1/2 Clean, Limestone Chips or Pea-size Clean Stone. Consists of small stones about 1/2″ - 3/8″ in size. This size makes it ideal for various applications, such as driveways, pathways, and as a base material for pavers and patios. The stones are generally angular in shape due to the crushing process, which helps them lock together effectively. Compared to #89 an #8 is more structural and versatile for base and drainage applications.
