Limestone SB2

Limestone SB2 is a dense, well-graded crushed limestone base material made up of stone dust and fines up to about 1.5 inch rock. Often described as 1.5 inch to fines, this blend compacts tightly to form a strong, stable foundation with excellent load-bearing performance. SB2 limestone is commonly used for road base, driveways, and parking lots, and as a base layer under asphalt or concrete where long-term durability and resistance to shifting, rutting, and settlement are critical. Because it locks together so well when compacted, it’s a trusted choice for heavy-duty construction projects that require a dependable compactable base.
