The step also involves making a drainage in the sides, for the water to drain out through the gravel base as shown below. This is the initial preparation for the construction.įig.2: Preparation of land by removing the upper layer The initial stage of floating slab construction is to clear the land and excavate the area as per the plan. The construction involves the following steps:įig.1: Floating Slab Layers A: Site Excavation for Floating Slab Construction The main construction layers in the floating slab are shown in figure-1.

So floating slabs are found most suitable and economical, compared with conventional slab construction. The construction of floating slabs requires details to start the proposed building requires a solid foundation to completely support the whole weight of superstructure.Īs mentioned they are more used in garages, an extension of the house or sheds that does not necessarily require huge foundations. A: Site Excavation for Floating Slab Construction.If it's the case, only after curing of the foundation we cast the floating slab. The floating slabs are called as monolithic slabs as they have no connection with the foundation. Here the need for ground preparation is reduced to a larger extent. Then literally the floating slabs float on the ground. Then we have the wall built up above the ground surface. When we assume a building with floating arrangement, we must picturize as a building with a standard foundation of strip footing, that is constructed several feet below the ground. The construction details are explained in detail in the following sections. It is economical when used in areas wherever the need for standard foundations is not required. The main application of floating slabs is to use as a base foundation for sheds, manufacturing workshops, home additional room, or garages. Floating slab, as the name tells it resembles a plate that is simply laid over water, with no kind of connection between them. 🕑 Reading time: 1 minuteFloating slabs are concrete slabs that are laying over the ground, without any kind of anchoring, as if it simply sits on it and floats.
