FEMA-Approved Safe Room Specifications

Foundation:
Our footings are 18 inches in depth by 20 inches in width and are required for our safe-rooms. We position 5/8 inch rebar in the footing vertically on one foot centers, two in the corners that rise out of the footing two feet or more into the wall voids which will soon be filled with concrete. By doing this our walls are tied to the a very large footing, buried 20 inches in the earth
