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.
