Precast concrete floors are designed primarily to eliminate shuttering and wet concrete pouring processes that make the construction of an in situ cast reinforced floor a slow procedure.

The advantage of the completely precast floor is that it can be constructed rapidly and readily it provides a platform from which further work on the building can immediately go on.

A disadvantage is that it is less easy to provide a rigid connection between the precast unit and the supporting beams or wall. The precast beam or the precast rib and filler block construction must act together as a single unit to horizontal actions (wind, earthquake).
