Concrete floors are critical elements in any industrial facility. This is particularly the case in high-bay warehousing, where high-tolerance, very flat floors are essential for the efficient operation of the materials handling equipment used. The benefits of using flat slab construction are becoming more and more recognised. Flat slabs without drops can be built faster because formwork is minimised and simplified plus quick turnaround can be achieved using a combination of early striking and flying systems. The overall speed of construction will then only be limited by the rate at which vertical elements can be cast.
