Floors are provided to divide a building into different levels for creating more accommodation one above the other within a certain limited space. The bottom floor near the ground is known as the ground floor and the other floors above it are termed as upper floors, like first floor and second floor. If there is any accommodation constructed below the natural ground level, it is known as basement and the floor provided in it is known as the basement floor.
A floor may consist of two main components:
- A sub-floor that provides proper support to the floor covering and the superimposed loads carried on it.
- A floor covering which provides a smooth, clean, impervious and durable surface.
