Floors

Floors belong to one of the most important functional components of a building. Floors influence the acoustics of a room: it depends on wheth­er a hard or soft flooring is used. Floors also react in various ways with light. Some flooring materials are known to produce mirror-like reflection. As to dark flooring materials, they, on the contrary, absorb light and this absorption makes a room darker. As to light materials, they reflect light and help create a lighter and brighter room.

Floors are subject to moisture, dirt, and dust. They are also subject to the action of feet and the load of furniture. That is why they require more cleaning and maintenance work than any other components of a building.

It should be taken into account that floors should be designed in such a way as to deal with the problems of sanitation, fire-resistance, and combustibility. They should also be designed so as to deal with the structural loads they will place on the frame of the building.

One should strictly follow the job practice for making poured-in-place floors. The measured materials for making the mastic must be put into the concrete mixer in the strictly correct order. The water and the emulsion should be carefully mixed till the mastic becomes homogeneous.

When making a poured-in-place floor, mastic is applied with a spray gun and its nozzle must be kept away from the floor surface.
