When ordering concrete for floor placement, you should order how much more than the measured volume for small orders?

• A. 0% more
• B. 5 to 10% more
• C. 10 to 15% more
• D. 20% more

Answer: (C)

When ordering concrete for floor placement, you add a cushion to the measured volume to cover waste and placement losses. For small orders, this cushion should be ten to fifteen percent. That extra amount accounts for concrete that spills or splashes beyond the form edges, minor misreads or miscalculations, and material that is used up in finishing and leveling processes. Since smaller pours have a larger proportion of potential waste relative to the exact measured volume, a larger cushion helps ensure you have enough concrete to complete the floor without delaying the project. Choosing zero percent would risk running short, and a smaller cushion like five to ten percent often isn’t enough for small pours. A twenty percent cushion is typically more than necessary and adds needless cost.
