# Floor Slab Floor slabs shall be as per the calculations of the structural engineer, but no less than a floor loading of 7.2 kPa (150 lbf/ft2). For elevated slabs, the concrete topping over metal deck flutes shall have a thickness of at least 100 mm (4 in) to allow for the adequate embedment of epoxy and anchor bolts. The floor slab shall be leveled and sealed with a non-penetrating seal, such as epoxy, which is a moisture barrier and prevents dusting and particulate. In order to accommodate initial or future high-density equipment (e.g., disk arrays, fully loaded server cabinets), a minimum floor loading of 12.0 kPa (250 lbf/ft2) is recommended.
