So, for example, a 32-inch-wide footing under an 8-inch wall would need to be at least 12 inches thick. Instead, however, you could reinforce the footing with transverse steel (running in the crosswise direction, not along the footing).In most residential situations, #4 rod at 12 inches o.c. will be plenty for 8-inch-thick footings up to 4 feet wide.The steel should be placed about 3 inches up from the bottom of the footing.n most residential situations, #4 rod at 12 inches o.c. will be plenty for 8-inch-thick footings up to 4 feet wide.

Say the concrete footing is 12 inches wide by 12 inches deep (don't worry about variations, just use the average). If we convert this to feet we have 1 foot by 1 foot. So, we will need 1 cubic foot per linear foot of footing.If you have 218 total feet of trench, you will need 218 cubic feet of concrete. There are 27 cubic feet in a cubic yard (concrete is sold by the cubic yard) so we divide 218 by 27 to end up with 8.07 yards of concrete. Order 9 yards at least.ay the concrete footing is 12 inches wide by 12 inches deep (don't worry about variations, just use the average). If we convert this to feet we have 1 foot by 1 foot.
