#11 Limestone is a fine crushed limestone aggregate, typically less than ¼ inch in size. It’s valued for its smooth texture, easy compaction, and excellent drainage, making it one of the most versatile materials for construction and landscaping. This fine limestone is commonly used as a leveling base for patios, pavers, and walkways, where a tight, stable surface is needed. It also serves as a top dressing for driveways, providing a clean finish that locks in larger aggregate below. Thanks to its high permeability, #11 Limestone is ideal for drainage control, backfill, and concrete mix stabilization.
