Limestone #4
Also known as: 1"–2" crushed limestone, 1x2 limestone (regional), large drain rock, ditch rock, erosion control rock
#4 limestone is a large crushed stone aggregate that provides excellent drainage and strong structural support, typically sized between 1 inch and 2 inches. This durable, angular rock is smaller than #2 stone but still heavy-duty, making it a reliable choice for road and driveway base support, construction fill, culverts, ditches, drainage systems, and erosion control. #4 limestone is commonly used anywhere you need stable, load-bearing stone that holds its shape while allowing water to flow freely in both construction and landscaping applications.
