The Danger of "Shorting" a Concrete Pour
Unlike pavers or decking, you cannot run to the hardware store if you are 0.5 cubic yards short on a concrete pour. If the ready-mix truck runs dry before the forms are filled, you are faced with a "cold joint"—which compromises the structural integrity of the slab and ruins the aesthetics.
Ordering an entire extra truck to deliver 1 yard of concrete is incredibly expensive and incurs "short load" fees. This is why mastering your cubic yard calculations is mandatory.
Why You Need a Waste Factor
A perfect 4-inch deep slab measuring 10x10 feet requires exactly 1.23 cubic yards. However, the ground is rarely perfectly flat.
- Uneven Subgrade: A dip in the dirt of just 1/2 inch across a 20-foot driveway requires significantly more concrete.
- Form Spillage: Concrete often spills over forms or is lost in the pump truck hopper.
- Standard Practice: Always add a 5% to 10% Waste Factor to your base cubic yard calculation.
Our tool allows you to instantly slide the waste factor up and down, showing you exactly how much buffer you are ordering from the plant.
