The purpose of floor is to provide horizontal clean surface to support the occupants of a building, furniture and equipments. The floor structure must be strong enough to bear super imposed loads. The strength of floor depends on type of flooring you use.
In addition to the flooring mentioned above there are some special types of flooring.
Concrete is produced by mixing cement with fine aggregate (sand), coarse aggregate (gravel or crushed stone), water, and often small amounts of various chemicals called admixtures which control such properties as setting time and plasticity. When the water is added to cement, it forms a slurry (thin semi-liquid cement) or gel that coats surfaces of the aggregate and fills the voids to form solid concrete.
The ratio of water and cement is the key that determines the strength of concrete whereas aggregates provide thickness, and decoration in some cases. Cement concrete flooring consists of cement concrete in the ratio of 1:2:4 (1 part of cement, 2 parts of coarse sand, and 4 parts of graded stone aggregate). Its thickness varies from 25mm to 50mm. The base concrete should be provided with slopes.
Flooring in veranda, courtyard, kitchens, and baths should have slope ranging from 1:48 to 1:60 depending on the location. Floors in water closet should have slope of 1:30.

Its thickness varies from 34mm to 28mm. Thickness of top layer of marble chips varies from 6mm to 12mm whereas the thickness of terrazzo flooring depends on the size of marble chips used.

This flooring may be used for auditoriums, dance halls, gymnasium floors etc. The thickness of wooden blocks does not exceed 10 mm. The blocks are laid in desired patterns and they are fixed by means of hot glue. Then they are nailed with the help of panel pins. The heads of these pins are punched off and putty is filled in the holes.

This flooring is a popular choice today. It is available in form of tiles and sheets which are made from synthetic rubber. It comes in plain, ribbed, fluted or other raised patterns. It is suitable for locations where a non-conducting floor (where heat or electricity can not pass through) is required. For e.g., laboratories, amusement parks, etc. This flooring is a mixture of raw rubber, fillers such as fiber, corks, etc. and pigments. A small percentage of ‘sulphur’ is added to speed up the process of vulcanization (The process of making soft rubber harder by reaction with ‘sulphur’ naturally). The material is available in different colors for both sheet and tile forms.
Rubber flooring can be laid over any smooth and dry surface. This flooring is elastic, attractive, noiseless, sanitary, comparatively warm and soft but it is affected by oil and grease. This flooring is used for bathrooms, hospitals, X-ray rooms etc.
