Concrete Slab Calculations Hansen Buildings
Concrete Slab Calculations. For a nominal four inch thick pour, I would divide the square footage of the total pour, by 81 to get the number of yards required. Let's consider a 24' x 36' pole building. 864 square feet of area divided by 81 equals Round up to the nearest whole yard and order 11 yards.
