Cinnamon Brown Decomposed Granite Driveway A Crushed Stone Fines Material. 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 90 square feet of a ground area at a 3" 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 120 square feet in a 3" 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. 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 flatter 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. 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.
