Graphite Grey D. G.
Crushed Stone Fines Material
Also makes a great less expensive alternative to crush oyster shell mix for Bocce Ball and Petangue court surfaces.
This is the deepest slate gray rock is ashen in color, but full of vitality. A primary color and texture component in many gardens.
One cubic yard of 3/8" decomposed granite or crushed stone will cover 108 square feet in a 3" inch layer.
Whether for driveways, pathways, patios, utility landscape areas or to surround trees, crushed stone or decomposed granite can be a versatile material that prevents weed growth, maintain even soil moisture and makes an outdoor space more appealing. These two are not the same material, though. Decomposed granite has a natural coarse look to it, while 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 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.
