. Floating slabs
Floating slabs are concrete slabs that are laying over the ground, without any kind of anchoring, as if it simply sits on it and floats. Floating slab, as the name tells it resembles a plate that is simply laid over water, with no kind of connection between them.
The main application of floating slabs is to use as a base foundation for sheds, manufacturing workshops, home additional room, or garages. It is economical when used in areas wherever the need for standard foundations is not required.
Construction of Floating Slab
The construction of floating slabs requires details to start the proposed building requires a solid foundation to completely support the whole weight of superstructure.
As mentioned they are more used in garages, an extension of the house or sheds that does not necessarily require huge foundations. These buildings are light in structure. So floating slabs are found most suitable and economical, compared with conventional slab construction.
🖍Advantages of Floating Slabs
• The floating slab construction can be employed in site areas with lower load carrying capacity and where investing large money on soil treatment is futile. This system let us to use over loose soil or in the soil with varying compressibility.
• Floating slab have the property of spreading the vertical loads or stresses coming over it to be distributed over a larger area.
• Floating slab foundations are a good solution when comes to extension of houses. There is situation when we require a building extension without affecting the already existing foundation. This won’t interfere with the building structures already built.
• Floating slabs behave as a barrier for the entrance of the moisture coming from the ground. It acts a barrier between the superstructure and the ground. This avoids seepage of water and frosting. For this purpose, the slab can be insulated for frost or moisture. This had made their widespread usage in cold region construction.
• The floating slabs do not require usage of footer trenches. They can be poured with the help of trenching or digging which is economical.
• The floating slab does not cause any disturbance to the earth layer lying beneath neither it will interfere with the quality.
• In areas where there are possibilities of shifting in the earth layer, mainly due to high moisture content, the floating slabs are best suited.
🖍Disadvantages of Floating Slabs
• The floating slab does not make underground land available for underground access for connection lines facing the utilities.
• It has a primitive technology
• Floating slab foundation have lower design resonance

The floating slabs are called as monolithic slabs as they have no connection with the foundation. If it’s the case, only after curing of the foundation we cast the floating slab.Construction of Floating Slab

1. Tied Column
This type of column is commonly construction from reinforced concrete. Longitudinal reinforcement are confined within closely spaced tie reinforcement. It is estimated that 95% of all columns in buildings are tied. @engineer03 #share

2. Spiral Column
Spiral column is also construction from reinforced concrete. In this type of column, longitudinal bars are confined within closely spaced and continuously wound spiral reinforcement.
Spiral reinforcement provide lateral restrains (Poisson’s effect) and delays axial load failure (ductile).@engineer03. #share
