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.
