Enter any rectangular or round pour for yards or bags. Under a yard you are usually hand mixing, and above that a truck starts making sense.
How it works
Area in square feet × thickness in feet gives cubic feet, plus your extra. Twenty-seven cubic feet make a yard, and an 80 lb bag yields about 0.60 cubic feet.
Before you order
- A yard of bags means mixing 45 of the 80 lb size, so price a truck before you commit.
- Ask the plant about short-load charges for pours under a few yards.
- Have a wheelbarrow path and helpers ready before the truck arrives, since delivered concrete starts setting at once.
Common questions
How many 80 lb bags are in a cubic yard?
About 45, based on a typical yield of 0.60 cubic feet per bag.
How much extra concrete should I order?
Five to ten percent is common for forms on level ground. Add more where the subgrade is uneven.
