Tons vs. Yards and Square Feet.
In most cases we charge by the ton and we have the receipts from the scale house at the quarry to show upon request. Materials sold by the yard tend to have very in-accurate amounts in the trucks. Amounts depend the size of the loader bucket, how well the material was scooped up and who was supervising the loading of the truck. Scale House totals don't lie, so why take a chance on losing money and time with how many square feet, scoops, skips and or dumps were made in loading the truck?Architects, public agencies, contractors and owner-builders requiring a competitive bid for the materials and transport costs should E-mail us with material specifications, amount and date needed and buyers contact information.

Product Specifications and Uses
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 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.
