Material glossary
Specialty products
Specialty products are the odds and ends that don't fit the usual categories — flagstone, boulders, ballast, glass gravel, unusual sizes and colors. Some are decorative, some are engineered for a specific job. All of them ship less predictably than #57 stone.
Every specialty family we track is below. If you don't see what you're after, ask — we quote plenty of these through our supplier network even when they aren't on the site. We deliver the ones with a green pill; the rest are here for reference.

How to choose within specialty products
Ask before you order
These aren't catalog items. Confirm size, color, and delivery window with the yard before you commit — every load runs differently.
Match the job to the stone
Flagstone, boulders, ballast, glass gravel — each has one right job. Get the job clear first, then the stone follows.
Lead time is longer
A specialty order usually ships slower than a #57 pallet. Plan the delivery date around the material, not the other way around.

Other material categories
Crushed stone
Crushed stone is rock that's been broken and screened into sizes.
Decorative stone and rock
Decorative stone and rock is what you see, not what you sit on.
Base materials
Base materials go under a driveway, patio, or slab — not on top.
Rip rap and armor stone
Rip rap and armor stone are the big pieces that hold a shoreline, a slope, or a culvert together.
Mulch and organics
Mulch and organics are the top layer that goes over the soil — bark, wood chips, compost, or a dyed blend.
Gravel
Gravel is loose stone in the size range you'd actually notice — pea-sized up to a few inches.
Sand products
Sand is fine crushed rock, small enough to pass through a #4 screen (about 3/16 of an inch).
Fill materials
Fill is what goes in the hole before anything else does.
Concrete aggregate
Concrete aggregate is the stone and sand that go into a concrete mix.
Screenings and stone dust
Screenings and stone dust are the fines a crusher makes on the way to sizing bigger stone.
Recycled materials
Recycled materials are crushed concrete, crushed asphalt, and reclaimed base — old road and slab work run back through a crusher.
Drainage materials
Drainage materials are clean, angular stone that moves water without holding it.
Asphalt aggregate
Asphalt aggregate is the stone side of asphalt — the sizes that get blended into a hot-mix or cold-patch recipe at the plant.
Bedding materials
Bedding materials are the clean, washed layer that goes around a pipe, under a paver, or behind a wall before backfill goes in.
Landscape
Landscape covers the loose stone and rock that go into a yard for looks — around a bed, along a border, or across a bare spot.
