Floors on ground without moisture, suitable for any coating

Some time ago bought a small house in the city. From the outset, I saw the cases of improvement and bringing to an apartment of this building set. But, having the desire to do something with their hands, the difficulty is not very scary. I will focus on one of the problems that arose in the implementation of "project-dream."

What to build the floors, make it warm and dry

The house, as it turned out, was built on the foundations of rubble having moisture feeds directly into the room. Wooden floors, which were originally built for the life of tens of years, began to "breathe", there were gaps between the boards. Moreover, during the examination of the existing floor, I noticed that even in the summer of underground moisture levels increased.

I decided to organize a concrete floor with a mandatory basement waterproofing on the perimeter.

Pros who have seen from this alteration:

- the sense of "land reliability under your feet," so many years lived in the apartment;

- the possibility of organizing a good level of waterproofing;

- more effective insulation;

- the use of technology for warm floors;

- provide a framework suitable for all finishing coating.

execution of works

Firstly, dismantling the old floor and making a recess of excess soil, sleep jobsite gravel mixture sand 100-120 mm thick, water and rammed prolyl-shifts - with larger logs handle. Naturally the operation performed by adhering level.

Reinforcement made of metal bars foundation from the outside and filled with concrete using formworks. Further reinforced cement mortar foundation room side and mounted primary coupler, which served as the basis for the threshold waterproofing. Immediately clarify that the work treated as a finishing pad, and tried to form an extremely smooth, without deviations, since this plane were to form foam sheets. Waterproofing applied roll bituminous material with layers of fiberglass.

You can use the roofing material, but with him, it seemed to me to work harder. Using solder burner strips laid and formed unbroken layer of insulating material to overlap the wall. At this stage, it was able to form an almost perfect surface for laying subsequent element of my "pie". Stepped insulation stacking step, which used the extruded polystyrene, which provides durability and has high strength.

I used material 30 mm thick, but the thickness is dependent on climatic features accommodation region. Although write that the polystyrene is not afraid of cement, in any case, laid on top polyethylene film having a thickness of 250-300 microns, a hydro finishing it and heat insulation work.

To mount a solid concrete slab, which will lay down the finishing screed, tied 8 mm grid of rebar and I put it on the film, raising to 15 mm, since the plate thickness chosen to 40 mm, based on the area of ​​the room. The network has technical information on the calculation of the thickness of the reinforced concrete floors, depending on the area. Filled to the desired value of the monolith and the maximum thickness of the concrete lined by weight level. You can use the beacons of the fill up, but I decided to compensate for the error slope finishing screed. Given that the entire process of the formation of the "pie" was carried out on the level, and the minimum was in fact the error "horizon."

A few weeks later, giving concrete gain strength, several times covering primed, filled and distributed according to the instructions Self-leveling screed.

The result is not very costly both in money and in the complexity of the process, was the effect of a plus sign in comparison with ordinary wooden floors. Gone damp, floors were much warmer and cover them became possible linoleum, parquet or laminate.

An important additional part applied home technology is that the methodology of the "pie" is quite suitable for the construction of underfloor heating. Only that instead of used me, polyethylene film will have to use the foil material is recommended for the installation of underfloor heating.
