Crushed StonesCA7 Crushed Aggregate
IDOT-certified CA7 crushed aggregate is a clean, angular ¾" limestone ideal for drainage, pipe bedding, paver bases, and concrete or asphalt mixes. Versatile and reliable, it's a staple material for both construction and landscaping projects.
CA7 Crushed Aggregate (IDOT Certified #016CA07) is a clean, uniformly sized ¾" crushed limestone commonly known as ¾" Limestone Chips or Binder. Its open-graded, minimal-fines composition makes it an outstanding choice wherever drainage, load distribution, or clean aggregate is required.
The angular, fractured faces of CA7 interlock effectively under load while still allowing water to flow freely through the voids — making it the preferred material for pipe bedding, French drains, and drainage ditches. It also performs exceptionally well as a paver base, in concrete and asphalt mixes, and as a decorative ground cover in xeriscaping and landscaping designs.
IDOT-certified and consistently graded, CA7 delivers the quality and uniformity that contractors and homeowners alike count on for projects both large and small.
Common Uses: Pipe bedding, French drains & drainage ditches, paver base, decorative rock/xeriscaping, concrete mix, asphalt, road & driveway bases, and fill material.
