What is good about pouring the floor modern polystyrene concrete

Among the new materials and technologies that have been developed and approved by specialists in the construction industry, a prominent place is taken by polystyrene concrete floor insulation. To make the floor warm enough 5 cm layer of this wonderful material. Polystyrene concrete can be applied in the same places, where the screed on the basis of cement and sand. On the finished hard surface you can easily lay tiles or other hard types of coatings. To date, the material is successfully competing for leading positions with other types of insulation for the floors. I would especially like to note that when pouring polystyrene concrete it is not necessary to carry out waterproofing.

Using polystyrene as insulation

The material is environmentally friendly heat and sound insulator. Prefabricated blocks serve as a good material for creating walls or partitions. The technology of floor insulation by pouring has become particularly popular. In the cured state, you get a solid surface that can be used immediately as a base for floor coverings: ceramic, wood, parquet, etc. For soft coatings such as linoleum requires additional screed of a small thickness (2.5-3 cm).

Advantages of polystyrene concrete floors

These include:

  • Good resistance to moisture, which is very important in case of accidents on the communications in the building;
  • The material tightly fills all possible cracks, which allows to eliminate the penetration of moisture, insects and foreign odors in the room;
  • Easily handled by different mechanical means. Very useful for subsequent repairs of communications;
  • Fast drying screed, easy to overlap.

Casting polystyrene concrete

In its composition, the material is similar to cement screed, where polystyrene is used as a filler. This affects the technology, which largely coincides with the standard method. The main difference is the thickness of the layer. For a normal floor, 5 cm is enough. If on top of the screed it is planned to lay a hard coating (tile, parquet, etc.), then after the filling it is not necessary to do anything else. Only for soft coatings you need a small additional finishing layer.

For the work you need:

  • Prepare the surface under the screed. There should be no construction debris and obvious irregularities;
  • A container for mixing (20 liters or more);
  • A drill with a nozzle or a construction mixer;
  • Metal rule and level;
  • Prepared beacons (wooden bars, metal profile, etc.);
  • Components for creating a mortar: cement PC400A, polystyrene in granules and additives. It is possible to use a ready-made mixture in bags.

First, the substrate for the floor is prepared. Pouring mortar is carried out on a clean surface without major irregularities. Protruding parts of the concrete slab should be cut down, holes and cracks should be filled with ordinary cement mortar. The difference between the individual points should be less than 1.5 cm. For better soundproofing in the future, it is necessary to glue a damping tape on the transition between the wall and the base. The next step is to place the beacons at intervals of up to 10 cm. You can use long self-tapping screws screwed into the concrete and fastened with dowels. The caps are aligned with the future floor. After the preliminary stage, the mortar can be prepared. About 10 liters of water is poured into a container and the mixture is poured. The consistency of the mortar should resemble a thick sour cream. This is what you should be guided by when pouring the ingredients. There is a detailed instruction on the bags with the ready-made mixture and you should follow it. The mixed mortar is poured onto the base. It is necessary to start from the far end of the room. Each batch is carefully smoothed with a rule or trowel. Small portions should be quickly filled into the filling area. Any surges near the walls must be removed quickly, because the mortar stops leaking after 20 minutes. For uniform drying, it is worth beware of drafts.

As you can see, the preparation and all the work is simple enough to perform the pouring of polystyrene concrete independently.
