San Diego Gray D. G.
This material is not a true decomposed granite but rather the stones fines resulting from crushing gray hard rock. This material makes a good alternative for those circumstances when a dark slate blue to gray color tone will make a great contrast in the landscape or compliment stonework in a pathway.
Also available with a stabilizer binding agent in it.
This is a MINUS gravel material that contains many smaller sizes of gravel and D.G. fines. The fines in this gravel help to "lock" or bind it down on the ground.
This product and similar materials are best used at the rates of:
1 Ton per 100 square feet in a 2-1/2 inch deep layer.
1 Cu. Yard per 125 square feet in a 2-1/2 inch deep layer.

Decomposed Granite and Crushed Stone Fines are not the same materials. Decomposed granite has a natural coarse look to it with irregular round quartz pebbles. Crushed stone products tend to be more flat and have a higher amount of fine material. Crushed stone products, granite, sandstone, limestone and others offer a greater array of natural colors to work with than most true decomposed granite materials.
Decomposed Granite Per Ton
As a general rule of 3/8" or 1/4" of crushed stone or decomposed granite material will cover a little over 100 square feet of an ground area at a 2-1/2" depth.
Decomposed Granite Per Yard
As a general rule 1 cubic yard of 3/8" or 1/4" of crushed stone or decomposed granite material will cover 125 square feet in a 2-1/2" inch layer. A cubic yard of moist crushed stone fines or decomposed granite material weighs more or less 3,000 pounds.

A proper DG surface does not move underfoot like sand or gravel, but its porosity allows water to penetrate to the soil below. That aspect makes DG or crushed stone fines a good paving material around trees and shrubs.
The standard application process is to spread about 2" of DG or crushed stone fines, water it thoroughly then compact it with a water filled sod roller, hand tamper or use a vibra plate it to settle. Then repeat the process with at least another 1" to 2" layer for extra depth for stability.
