Performance Standards for Concrete Slab Foundations, excluding Finished Concrete Floors. (1) Concrete floor slabs in living spaces that are not otherwise designed with a slope for drainage, such as a laundry room, shall not have excessive pits, depressions or unevenness equal to or exceeding 3/8 of an inch in any 32 inches and shall not have separations or cracks that equal or exceed 1/8 of an inch in width or 1/16 of an inch in vertical displacement. If a concrete floor slab in a living space fails to meet the standard stated in this paragraph, the builder shall take such action as is necessary to bring the variance within that standard.
