Limestone #57

#57 limestone is one of the most popular and versatile crushed stone sizes, commonly used for drainage, base support, and concrete applications. This medium-sized, angular aggregate typically ranges from 1/2 inch to 1 inch, made up of stone that passes a 1 inch sieve and is retained on a 1/2 inch sieve. Because it’s strong, durable, and drains well. Widely used for French drains, retaining wall backfill, foundation drainage, driveway and walkway stone, pipe bedding, and as a clean, reliable aggregate in concrete mixes where consistent sizing matters.
