What Is Monolithic Slab?

The word monolithic means “single pour over a wide area”. Monolithic slabs are widely used as foundations in construction. In monolithic slab as a foundation is done by a single pour concreting. This method increases the thickness of the concrete slab under the load-bearing walls.

Monolithic slabs can be constructed very easily and quickly. This method is easily done for a large area so the labor cost is less. In addition, concrete is poured into the monolithic slab at the same time.

For monolithic slab foundation, most of the construction area is leveled and compacted.

The monolithic slab foundation method allows the load of the structure to be distributed evenly over the ground and this type of foundation, it makes the area compact.

Where the area has a small slope of the soil, a monolithic slab foundation may be a suitable option for house construction.

A monolithic slab can be equally strong as a stem-wall slab when it comes to building a monolithic slab foundation using ideal conditions and proper specification.

Its use should be avoided in situations that do not suit the monolithic slab foundation. It is not advisable to do this foundation when filling material like solid waste is used in the soil.

Monolithic slab foundations should not be used in flood-prone areas. Because this foundation is built about 6 inches below the ground.

In some cases, monolithic slabs tend to crack around walls and other large load-bearing areas. Cracks can occur in a monolithic slab foundation if the construction of walls and floors is not done with a concrete frame structure.

What Is Floating Slab?

Floating Slab (1)

Floating slabs are made on the floor surface without any anchoring on the ground. It sits easily on the surface. The floating slab is simply laid over the water, with no connection between them.

Floating slabs can be used as a base for various structures like industrial sheds, car garages, cottages, drive shed, ancillary buildings, and pantries.

Floating slabs are not connected to the foundation. It works independently.

The construction work of a floating slab is expensive. Because the construction of this floating slab has to go through various processes. This process involves digging and concreting for strip footing. In addition, it includes labor costs.

Floating slabs are a good alternative to provide a strong surface for the construction of industrial sheds, but are expensive for the construction of ordinary houses.

The main advantage of a floating slab is that it acts as a barrier to the entry of moisture from the ground into the house. It acts as a barrier between the superstructure and the ground. This counteracts the effects of moisture in natural conditions like water and frost.

Floating slab foundations are the perfect solution when the need arises to raise any home. The floating slab foundation allows the building to provide the necessary foundation for the expansion of the building without damaging the existing foundation. In addition, the floating slab foundation will not affect any part of the building structures.

Difference Between Floating Slab and Monolithic Slab

Difference Between Floating Slab and Monolithic Slab (1)


  • Floating slabs are sometimes called monolithic slabs on the basis of function because the floating slab foundation has no contact with the ground. Floating slabs are used as support for some construction structures. The floating slab is removed after the foundation of the building has been strengthened.
  • Using a monolithic slab foundation is less expensive than a floating slab foundation. Floating slabs are concreting in 2/3 steps in the shape of a seamless slab. monolithic means a continuous process. Which is uniformly poured concrete for the foundation of the building.
  • The choice of the floating slab is appropriate when constructing a building with high loading in areas where the soil is loose and unstable. In addition, floating slabs are suitable for building only deep foundations and for garage-like works.
  • Floating slabs can be built on the ground or in snowy areas. Which floats on the ground. Therefore a floating slab in such an area is commonly called a monolithic slab because this type of foundation has no contact with the ground.
