Virtually installation of prefabricated monolithic inter-floor covering made of ceramic blocks is no different from the one, where concrete or gas-concrete blocks are used. The process starts with arrangement of supporting beams, having exposed reinforcement cage. The beams must rest on a cast-in place reinforcing belt of at least 120 mm. Spacing of the beams depends on the size of the blocks. Once this is done, ceramic blocks are placed on the beams tightly against each other in longitudinal rows with reinforcement mesh being then laid over. Finally, all spaces between the blocks are filled up with concrete which class is not less than B15. The concrete is also poured on top of this structure (thickness of 40-60 mm) and supports.
Blocks for inter-floor covering

Achieved inter-floor covering can be used in private housing construction, where the spans are up to 7 m and load is up to 500 kg per sq.m.

Advantages of this are:
- Safety - No materials representing a threat to human health are used when constructing this inter-floor covering;
- Technological mobility – Works can be performed without the use of heavy lifting machinery. Inter-floor covering can be arranged in the building, which already has a roof. This is especially convenient when reconstructing the buildings;
- Low heat transmission - Figure of heat transmission in ceramic blocks is 0.16-0.20 W/ms, which makes staying in the house comfortable without the need to use additional heat insulation during spring and fall;
- Durability - Slab cast over precast joists, manufactured with the use of ceramic blocks, can last more than 100 years;
- Fire resistance - Inter-floor covering is non-flammable, preventing the fire spread. There is a chance that it can be used again if it has not been exposed to the fire for more than 1 hour;
- Lightness of materials - Most common ceramic blocks weigh from 9 to 18 kg. Having high floor loading capacity, inter-floor covering made of ceramic blocks is significantly less heavy than its concrete analogs. 200 sq.m of it reduces the load on the foundation by more than 20 tons;
- Excellent sound-proof qualities - Thanks to porosity of ceramics and presence of voids in the block itself, the sound, traveling through the inter-floor covering, dissipates;
- Breathability - Structure is able to “breath”.
