If you’re looking to get your hands on some decomposed granite, there are two main options: Retail or straight from a quarry.
- Retail: Some home improvement stores such as Lowe’s and Home Depot, landscape supply stores, or Rockery (Stone Yard) supply bagged gravel. You can visit a local store or check out their websites. If you are working on a large project, some suppliers will be happy to deliver in bulk at a fee.
- Direct from Quarry: It is way cheaper to buy from a quarry, especially for bulk orders.

Decomposed Granite Price
As of the time of writing, decomposed granite costs anywhere between $80 to $170 per cubic yard.
Remember to factor in delivery costs too if you are not in a position to haul the material yourself. Most suppliers are happy to deliver the material on-site at a fee of course.
How much DG to buy
There are a few factors to consider, like the scale of your project and compaction rate.
- Measurements: First, determine the length, width, and depth of the surface to be paved, by the foot. With this, you can estimate the volume of material required in cubic feet. But since most gravel and sand material is sold by cubic yards, divide the volume by 27 to convert to cubic yards.
- Compaction: DG must be compacted well to create a stable, durable, and smooth surface. This entails compacting it in lifts, layer after layer. Compaction eats into the amount of material and so should you adjust the volume accordingly. A 25% compaction rate is typical for decomposed granite. This means you will need about 30% more material to account for compaction.
That’s it, until next time folks!
