A construction joint in a concrete slab on composite metal deck features keys measuring one foot long by the depth of the concrete over the deck spaced at four feet on center across the joint. The slab reinforcing remains continuous through the joint. The joint width is detailed at three-quarters of an inch. Concrete pour ratios are limited to a maximum of two to one in length-to-width ratio, and joint locations require submittal review.
