How to measure
Measure the length and width of the slab in feet. Check the depth of your forms or excavation in inches at several spots and use the average.
Tips from the field
- Driveways are usually poured 4 to 6 inches thick. Go thicker where trucks or heavy loads will park.
- Past about 1 cubic yard, a ready-mix truck is usually cheaper and easier than bags.
