Aggregate Materials
We offer a wide selection of materials, to help meet any of your project requirements.
Granular Materials
Aggregates made from screening natural sand deposits. Particles are smaller than 3 inches (75mm), but in general, range from a No. 4 sieve (4.75mm or 0.187" per square mesh opening), to a No. 100 sieve (0.150mm or 0.0059"). Compaction Fill is a byproduct of concrete crushing.
Class II Fill Sand
Used as beneficial fill material on construction projects.
Compaction Fill
Used as beneficial fill material on construction projects.
Fine Aggregates
Aggregates comprised of finer rock fragments that mostly pass through the No. 4 sieve, but are larger than a No. 200 sieve (0.075mm or 0.0029"). These aggregates are typically blended with course aggregates to produce Portland Cement or Hot Mix Asphalt (HMA).
2NS Sand
Used for concrete mixes, base material for concrete pavers, and for pressurized, elevated sewage disposal systems. Also used for traction during slippery road conditions [ice control sand].
Mason Sand
Used to make mortar, paver base/joints, and landscaping. Also used for traction during slippery road conditions [ice control sand].
Paver Base
Used as a leveling sand, for providing a firm, stable base underneath landscape blocks, stepping stones & patio pavers. Kalamazoo Reserve only.
Winter Sand
Used specifically for traction on airport runways during icy conditions. Kalamazoo Reserve only.
Dense Graded Aggregates
Aggregates made up of rock fragements that are smaller than 1.5 inches (37.5mm) in size. These aggregates have the ability to be very stable and tightly compacted. Commonly, they are used as either a road base or surface course layer, and for shoulder work.
Crushed Asphalt
Used as a surface course for roads, driveways, parking lots, and walkways. Oils in the asphalt have a tendency to heat-up on warm sunny days, which causes some of the "fines" to bind together, making this product much less "dusty" than crushed concrete or natural road gravel products.
21AA Crushed Concrete
Used mainly in road construction, as a surface layer for driveways, and parking lots. Packs and drains well. Good for bridging wet areas.
21AA Crushed Stone
Used for gravel roads, driveways, parking lots, and underneath asphalt paving.
22A Crushed Concrete
Used as a top course for roads, driveways, and parking lots. Is very similar to 21AA products, but particles are generally smaller with more "fines" which makes for a nice driving surface. Also, can be used underneath asphalt paving.
21AA Limestone
Used mainly in road construction, as a surface layer for driveways, and parking lots. Packs and drains well. Good for bridging wet areas. Kalamazoo Reserve only.
23A Road Gravel
Has a higher clay content than 22A, and is typically used to build up and maintain road shoulders.
Open Graded Aggregates
Aggregates that are typically more course in gradation with little material finer than the No. 200 sieve. These aggregates drain well, and are typically used as a base course under concrete & HMA pavement.
3/8" Crushed Stone (34G)
Used as a base material for road construction, driveways, and parking lots. More pervious than 21AA.
3/8" Washed Pea Stone (34R)
Used for drainage, landscaping, playgrounds, walkways, and dog runs. An excellent fill material.
Course Aggregate
Aggregates typically containing particles less than 3 inches or 75mm in diameter, with a small amount of material passing the No. 4 sieve (4.75 mm or 0.187 inches per square opening).
6AA Limestone
Used for storm and sewer tile drainage, and landscaping.
6A Washed Stone (1" Minus)
Used for septic systems, and decorative landscaping. Great for allowing water to drain through. Also, used in some types of concrete mix.
1" x 3" Crushed Concrete
Used as a base for road, and driveway construction. Good for bridging over wet areas.
5/8" Washed Pea Stone
Used for drainage, landscaping, playgrounds, walkways, and dog runs. An excellent fill material.
1" x 2" Washed Stone
Used for landscaping, and flat roof applications.
1/2" Clean Crushed Stone (No Dust)
Used mainly for overlaying driveways, and for backfilling retaining walls.
6AA Clean Crushed Stone (~3/4")
Used mainly for overlaying driveways, and for backfilling retaining walls.
1/2" Crushed Stone (with Dust)
Used for driveways, and as a base material for retaining walls and brick & block patio pavers.
1/2" x 1" Crushed Concrete
Used as a less expensive and "green" alternative to crushed stone for driveways.
17A Limestone
Used for drainage. Generally runs slightly smaller than 6A Washed Stone. Kalamazoo Reserve only.
11A
Used for drainage. Generally runs slightly smaller than 6A Washed Stone. Kalamazoo Reserve only.
14A
A mixture of 6A Washed Stone and Sand. Kalamazoo Reserve only.
Oversize Stone
Riprap, also referred to as cobble, is comprised of loose, angular stones, typically made from granite, limestone, or concrete rubble. Boulders, are rock fragments typically larger than 10 inches in diameter.
3" x 6" Crushed Concrete Rip Rap
Used to armor erosion-susceptible shoreline.
Boulders (18" Plus)
Used as decorative landscaping, and for building retaining walls.
1” x 3” Limestone
Used as a base for road, and driveway construction. Good for bridging over wet areas.
3"-8"" Limestone Rip Rap
Used to armor erosion-susceptible shoreline.
8"-18" Limestone Rip Rap
Used to armor erosion-susceptible shoreline.
2"-3" Slag
Used as a base for road, and driveway construction. Good for bridging over wet areas.
Topsoil, Dust, and Compost
Topsoil is the outermost layer of soil, typically found to be between 2 and 12 inches deep, and rich in organic matter & microorganisms. Compost, or humus, is the nutrient rich organic matter byproduct, of the controlled decomposition of green (yard) waste. Stone Dust, or Fine Crush is the byproduct of crushing concrete and stone, is powder-like in nature, and contains small amounts of stone that are typically less than 1/8" in size.
Screened Topsoil
Used for garden and yard applications, allowing for water and nutrients to flow naturally, creating a healthier growing space.
Unscreened Topsoil
Used for leveling, wall support, raised bed filler, and for building up low lying areas and/or holes.
Screened Topsoil/Compost "Blend"
Used as a planting media in both garden and yard applications. Also provides erosion and moisture control.
Compost
Used as a planting media, and for providing both erosion and moisture control.
Stone Dust or Fine Crush
Used as a base material of brick & block pavers. Can also be used for baseball diamonds, and other playing field infields.
