Blue-Gray Granite ¾"

Blue-Gray Granite ¾" — The Workhorse Crushed Stone for Driveways & Drainage

Native Boston-area blue-gray granite — not to be confused with Pennsylvania/New York bluestone.

Our ¾" Blue-Gray Granite is the standard-bearer of New England crushed stone — the size driveway pros reach for, the size drainage installers spec by name, and the size that gives outdoor projects that classic, intentional blue-gray look. Big enough to take vehicle weight without crushing, small enough to spread evenly with a rake.

At a glance

What it's good for

• Residential and commercial driveway top coats and re-bases
• Patio and walkway base layers under pavers and flagstone
• French drains, foundation drainage, and downspout dispersal
• Decorative ground cover in beds with chunkier visual texture

How much do I need?

For a 600 sq ft driveway top-coat at 3" depth, plan on about 5.5 cubic yards. A 50' French drain trench (12" wide × 18" deep) needs about 2.8 yards. New patio base under 200 sq ft of pavers at 4" of ¾" stone runs about 2.5 yards (with dense pack typically below).

How Blue-Gray Granite ¾" compares

• vs. Gray Granite ¾": Same size and crushed structure; blue-gray reads cooler with a steel undertone, gray is the classic neutral pick.
• vs. Blue-Gray Granite ½": ½" is the smaller walkway/detail size. ¾" is the driveway and base workhorse.
• vs. Dense Pack ¾": Dense Pack has fines mixed in for compaction. ¾" blue-gray is clean for drainage and finish. Common stack: Dense Pack base + ¾" top.
• vs. PA Bluestone: Different products entirely. PA Bluestone is flat sedimentary flagstone for patio surfaces; this is crushed igneous granite for bulk material.

Frequently asked questions

Is Blue-Gray Granite ¾" the same as bluestone?
No — bluestone is a flat flagstone from PA/NY used for patio surfaces. Blue-Gray Granite is our native Boston-area crushed granite with a blue-gray color profile. Same name family, completely different products.

Will Blue-Gray Granite ¾" stay put in a driveway?
Yes. Angular crushed granite is the right pick for driveways — the angular faces lock together so the gravel doesn't migrate under tires or get scattered by a plow.

How does Blue-Gray Granite ¾" compare to Gray Granite ¾"?
Identical size and crushed structure. Blue-gray has a cooler steel undertone; gray is the neutral classic. Color preference only.

Can I use Blue-Gray Granite ¾" under pavers?
Yes as the drainage layer, but for the structural base under pavers, use Dense Pack ¾" to minus — it has fines mixed in to compact tight. Common stack: Dense Pack below + Blue-Gray ¾" on top.

How much does a cubic yard of Blue-Gray Granite ¾" weigh?
About 2,500–2,700 lbs per cubic yard, or roughly 1.25–1.35 tons.
