The installation of concrete floors is preferably where greater base strength is required. Naturally, they have other advantages. So, they are distinguished by fire safety, chemical resistance, antistatic. Although there are disadvantages: poor resistance to wear, as well as the release of a large amount of dust during operation.
Laying of such a floor must be done according to a certain technology. It should be noted that for work it is necessary to choose high-quality materials. It is also necessary to carry out preparatory activities. The base should consist of gravel and sand. Its thickness can range from 20 cm to 1 meter. If the previous concrete floor is used as the foundation, then it should be as even as possible. In the presence of strong differences, it is necessary to make a leveling screed.
Further, the technology of the device of concrete floors provides for the organization of a waterproofing layer. Most often, a special film is used for this purpose. Now you can install the formwork for the future floor. Its size depends on the area of the base. If it is too large, then the filling is carried out in parts (cards).
Naturally, the device of concrete floors does not do without reinforcement, therefore, before pouring, it is necessary to lay a steel mesh or rods on the base. Now you can start mixing the solution, into which various substances are often added, which prevent the strong shrinkage of concrete and its cracking. You can buy a ready-made mixture in which you just need to add the specified amount of water.
Next, the base is filled. During operation, it is desirable to provide appropriate conditions that will contribute to the normal solidification of the solution: the absence of drafts, a certain air temperature. Important: it is impossible to accelerate the drying of concrete, since subsequently it can quickly crack.
The device of concrete floors involves leveling the layer of the mixture, as well as its compaction. The best device to perform this action is a vibratory beacon. However, it must be used very carefully so that the mixture does not exfoliate. It should work at low speeds.
After the solution is completely ready, you can leave it to dry. The solidification period of the mixture depends on the material used. Basically, it lasts from 7 hours to 7 days. Further, the device of concrete floors provides for grouting the surface, which ensures its evenness and smoothness. After that, you can cover the surface with a special composition that is used to harden concrete. It also prevents dust formation during operation.
Further, the device of the concrete floor continues with the organization of the finish coating, which will close the pores and prevent moisture and dust from entering. Dry mixes are most often used for hardening, which you just need to rub into the surface. Such actions provide a beautiful appearance of the floor and improve its quality characteristics.
