Screed
Floor tie - universal durable way. It is perfectly suited to any type of further finishing coat, is able to hide communications and the system of the warm floor, and in itself can become a decorative finishing method of flooring. All these advantages explain the incomparable popularity of the screed as a rough or final finishing coat. The method is suitable for residential, non-residential, industrial, commercial and other premises. Can be unreinforced and reinforced.
The main disadvantage is the large weight of such a cover, but there are also loopholes here, how to avoid excessive load on the floors - for example, for warming and thickening of the layer, you can use expanded clay. The method requires a lot of work and skill, and also very long in time. Waterproofing - is necessary to prevent leakage of the composition. However, even with such a list of shortcomings, it is quite feasible for the layman to level the floor with his own hands by means of a screed.
Semi-dry screed
The method is completely identical to the previous one, except that the possibility of leaks to the lower floors is reduced to a minimum. For multi-storey houses, of course, this method is given priority, due to the absence of a threat of accidental damage to property.
Self-leveling self-leveling floors
All kinds of liquid mixtures, except for polymeric ones - this is also one of the types of screed. However, this option to implement their own hands will be much easier, thanks to the physical characteristics of the solution. As its name implies, the mixture does not require the installation of lighthouses. The main thing is to evenly spread the solution over the surface in the room, and then the composition itself, under the action of the force of attraction, is leveled to a perfectly flat horizontal surface.
Self-leveling floors, except for polymeric bulk mixtures, it is also a kind of screed. However, unlike traditional screeds, they are less labor-intensive in carrying out work. This is due to the special composition of the mixture. If the alignment of a conventional cement mortar requires the installation of beacons and thorough smoothing, the floor is self-leveling. Those.it should be applied evenly to the surface. Further, under gravity, it assumes an ideally horizontal position. 
This mixture will be an ideal basis for absolutely any finish flooring. In technical rooms may not require additional coverage.
Despite the specific complexity of implementing any of the types of screeds, this way how to make floor leveling with your own hands is not just a place to live, but really deserves its popularity. The universality and durability of this type of floor speak for themselves.
Wooden floors
Wooden floors are inferior to cement screeds for durability, however, just like several years ago, it enjoys well-deserved popularity. It is explained by greater speed and simplicity of installation, quick commissioning, soundproofing and warming properties. 
Floors with ladders
The most common type of wooden floor is the construction on logs( wooden blocks or boards placed on the edge).The logs are installed on the base( they can even just land), and the board is already attached to them. Thus it is possible to realize both a rough floor( requiring additional coverage) and a finishing( everything depends on the quality of the applied board).
The voids between the lags under the boards can contain heat-insulating materials, hide communications.
This option is very easy and short-time to implement on its own, after which he will immediately be ready for use. 
Advantages are obvious, but there are a number of shortcomings. Wood is a short-lived natural material. It is absolutely not suitable for "wet" areas, rooms with high humidity. And even in suitable premises, after a decade or two, the wooden floors will begin to crack and creak, and possibly also sag. In such cases, it is possible to level the wooden floor with your own hands.
How to level a wooden floor?
If the wooden floors are twisted and creaking, you need to determine how their components are damaged. It is hopelessly damaged elements that must be completely replaced in order to eliminate the creak of wooden floors and their irregularities. Most often it is enough to replace the substrate - thick plywood or floorboards, which are attached to the logs. However, it also happens that it requires a complete repair of the wooden floor, when it is almost necessary to completely remove it and replace it with a new one.
Adjustable version of
You can not just take and give up the advantages of a wooden floor, so engineers came up with a design method called an adjustable floor. In this version, the lags will be installed not on the base, but on a special firmly fixed structure. Finishing material can be absolutely anything.
In this case, users of the room can easily adjust the height of a site without much effort. Carry out floor leveling with your own hands, if you have installed adjustable structures - it's easy.
Dry screed
The ideal way to level the surface - it combines the advantages of both screeds and adjustable construction. In this situation, the free-flowing filler is poured out and leveled, which is covered with sheets of GVL.The only and main disadvantage of this method is sensitivity to moisture, therefore for "wet" zones it does not fit categorically. 
Conclusion
Which of the following methods to choose the floor is not so much a matter of preference, but a question of possibilities. Basically, it all depends on the original materials used in the floor structure, but even in this case there is room for reflection.
