Sand & GravelFM20 Manufactured Sand
FM20 Manufactured Sand is a clean, finely crushed washed sand engineered for consistent performance in concrete, asphalt, pipe bedding, and base applications. A reliable, high-quality alternative to natural sand.
FM20 Manufactured Sand — also known as FM-20 Sand, Washed Concrete Sand, FM20 Stone Sand, and Manufactured Sand — is a precisely graded, crushed fine aggregate produced to meet the strict quality demands of modern construction. Unlike naturally occurring sands, FM20 is mechanically processed and washed to achieve a uniform particle size, clean surface, and minimal fines content, resulting in a highly consistent and workable material.
Its well-graded particle distribution makes FM20 an excellent component in concrete and asphalt mixes, improving workability, strength, and finish quality. The material's angular shape enhances bonding within mixed applications, while its clean, washed profile makes it equally effective as a pipe bedding and trench backfill material, providing stable, void-free support around buried utilities. FM20 also performs well as a base material and in a variety of landscaping applications.
Whether used in large-scale infrastructure or residential projects, FM20 Manufactured Sand offers the uniformity and performance that professionals depend on.
Common Uses: Asphalt production, pipe bedding & trench backfill, concrete, base material, and landscaping.

FAQs
CA6's blend of crushed stone and fine particles allows it to compact tightly, creating a dense, interlocked layer that resists shifting, settling, and erosion — making it one of the most reliable base materials available for roads, driveways, and foundations.
Absolutely. CA6 is one of the most popular choices for residential driveway bases. It compacts firmly underfoot and under vehicle traffic, providing a stable, long-lasting foundation that holds up through freeze-thaw cycles and heavy use.
Yes. CA6 is IDOT certified under specification, ensuring it meets Illinois Department of Transportation standards for quality, gradation, and performance.
For most driveways and light-traffic applications, a compacted depth of 4–6 inches is recommended. For roads, heavy equipment areas, or building foundations, 6–12 inches or more may be required depending on soil conditions and load requirements.
