A concrete house is right choice, because it is much more durable and stronger than brick. However, it is necessary to distinguish between technologies for building houses from monolithic concrete and concrete blocks, since these, as they say, are two big differences. This article will focus on the first case, in which the structure is a single non-prefabricated frame, which can then be finished to improve the appearance.
Why is it worth building a monolithic concrete house?
Solid structures have a lot of advantages over prefabricated ones: higher reliability, longer service life, low heat transfer rates, and so on. Let's take a closer look at the advantages of monolithic houses:
- Reliability . Since a seam always has lower strength than the material it joins, it can be concluded that the fewer seams the better, and ideal option- when there are no seams at all. Such houses are very common in seismically active areas, for example, in Japan, where earthquakes occur almost every month, almost all houses, including multi-storey ones, are built using monolithic technology, so they can easily withstand even the strongest shocks. Also, in places where there is fighting, monoliths are also quite popular, and Israel is a prime example of this. Good one-piece concrete house it can withstand a direct hit from a rocket, and although the glass will still be broken, at least you won’t have to rebuild it.
- Long service life . If you build a house out of brick, it will undoubtedly last a long time. Your children, and even a few grandchildren, can live in it before it has to be completely renovated. But a monolithic concrete house will give a roof over the heads of your grandchildren, great-grandchildren, and even great-great-grandchildren, which, of course, is very nice. The thing is that any structure wears out over time, but what quickly deteriorates is not the material itself from which it is built, but the seams connecting the blocks. For example, in brick house The layer between the bricks deteriorates very quickly, and after it they themselves begin to collapse. But since there are no seams in a monolithic house, the only thing that can deteriorate is the concrete itself, and as we know, it lasts a very long time.
- These houses are warmer . The absence of seams avoids the presence of microcracks through which air passes, taking heat with it. In addition, these microcracks tend to diverge over time, as air currents erode their edges. This is not the case in monolithic houses, so they can be built even in areas where there is wind. strong winds- there will be no draft.
- Prospects . With the development of 3-D printing technologies, it has become possible to literally stamp houses using a 3-D printer. This does not require workers or complex building structures, and the procedure itself will only take a couple of days. Imagine how a huge self-propelled printer with a dozen tanks of liquid concrete arrives at the site of your future home and starts printing your house - fantastic! Of course, this is not yet technically feasible, but in the future, in 30-40 years, they will build this way.
Flaws
The main disadvantage of monolithic houses is high price . While the technology for 3-D printing of residential buildings is very poorly developed and is only capable of serving the low-budget sector, monoliths have to be built manually. But the procedure for constructing a monolithic house is quite difficult and therefore requires highly qualified builders.
The most difficult thing here is the construction of the formwork into which liquid concrete is poured. The fact is that if you install it incorrectly, then during filling it will simply break and all the concrete will spill out. This problem is especially acute in areas with soft soil, as it also contributes to its loosening.
From experienced craftsmen construction work there are secrets to how to strengthen the formwork, and that is why such workers are very expensive. Building a monolithic house on your own is far from the best idea, which is why there are relatively few such structures in our country.
The need to create high formwork. As already mentioned, the construction of solid concrete houses requires reliable scaffolding, which will not fall apart at the most crucial moment. Only an experienced team, which has already been involved in similar constructions many times, can design and build such floors. And of course, developing forests takes time.
Difficulty in installing concrete floors. The fact that concrete can break through the formwork is only part of the problem. In fact, quite often when it is built by unskilled workers, it breaks under its own weight.
High quality concrete required. Finding good concrete is no longer an easy task, but this is the main thing when constructing a solid concrete house. After all, the service life of good and bad material can vary significantly (by 3-4 times). There is a widely known case when the Moscow Voentorg concrete store, built of concrete in 1912, became unsafe after only 80 years, although it should have stood for at least 250.
These 4 problems are the main obstacles to the popularization of concrete houses in our country, and it is because of them that only people with high incomes can afford the construction of monoliths. Therefore, if the budget does not allow, it is better to build from brick, as it will last longer than a low-quality concrete house built by cheap workers.
When starting to build your own home, the question invariably arises of what material to make the walls from. Typically, the materials for building houses were either wood or stone (brick, concrete and ceramic blocks). And when choosing, we were guided by the following - wooden houses warmer, lighter, they breathe, but they burn too well. Stone houses more durable, reliable, but too heavy and cold.
Scheme of foam concrete masonry.
Meanwhile, construction technologies do not stand still, and now many new building materials and new ways of constructing buildings have appeared. One of these innovations is the technology of monolithic construction of houses. It is this that has become the construction standard in recent years, and is used in the construction of modern houses, since the speed of work is several times higher than the speed of work using conventional methods.
With proper design of a series of windows, you can decorate any of the rooms in the house (bedroom, living room, nursery, kitchen or dining room, billiard room and other rooms). Eat important points, which should not be forgotten when making a bay window. Firstly, its presence should not affect the temperature in the room in winter, so heat leakage must be prevented. The second point is that on the south side of the house too much heat can penetrate through the bay window in the summer. If your bay window is located at the very sunny side, nothing fits better than these blinds - http://xn—-7sbhaociizf7a6ap5n.xn--p1ai/zhaluzi-stavropol. Well, don’t forget that the most important function of these windows is to illuminate the room. This architectural design also has a disadvantage - a large window requires a lot of fabric to close it. But even this minus can be avoided if you decorate the interior in Japanese style or hi-tech. In this case, you can use rolled or screen canvases, which will fit perfectly into the design and prevent the penetration of excess light.
The construction itself is fundamentally different from the construction of houses made of timber, reinforced concrete products and bricks. A simplified construction of a building using this technology is as follows: directly on the foundation of the future house, formwork is installed along the contour of a wall or, for example, a column, where reinforcement is installed and concrete is poured. When the concrete has hardened, the formwork is dismantled, and a finished part of the wall or column is obtained.
Roughly speaking, poured houses are houses made of concrete covering a “skeleton” of reinforcing mesh.
There are two ways to build a house using this technology: by making the walls completely cast or by combining a monolithic frame with walls made of hollow blocks. Of course, such a structure - complex design, its strength and stability depend on correct engineering calculations. When the house is made completely cast, the formwork is done around the perimeter of the entire house, leaving space for entrance and interior doors, and then (at the window level) for window openings.
New type of construction
Scheme of a wall made of poured foam concrete.
As usual, a foundation needs to be made for the building. Here we also do it, but again, depending on the soil, it must be made 20-30% wider and deeper than when building a brick house.
Now, to the reinforcement of the foundation frame at the corners and at the junctions of the partitions, you need to attach the following frames from the reinforcement with tying wire (making them above the pouring level) and fill them with concrete.
At combined construction Columns of the required height (size 40x40 cm) are poured with concrete, at the ends of which protruding parts of the reinforcement are left to make the lintel frame. In this case, the lintels (their size is also 40x40 cm) will seem to hang in the air, and you will get a concrete frame. Gaps can be laid foam concrete blocks, brick or fill with sawdust concrete (the composition for filling the walls is prepared from a mixture of sawdust, cement and sand in a ratio of 1: 2: 6; practicing builders recommend using large wood chips soaked in lime mortar instead of sawdust).
If we plan to build a second floor, then we continue to do everything in the same way, only with lintels on the window and doorways with a width of 40 cm, they will have a height of 20 cm. In terms of seismic resistance and bearing capacity such a design will comply with building codes.
Upon completion of this work, you can begin installing the roof and interior decoration of the room. Concrete lintels allow the installation of floor slabs, as they are very durable. The outside of such a house requires decorative finishing.
Reasons for use
When determining the feasibility of using a technology for constructing a poured house, one should compare its advantages and disadvantages.
Heat block diagram.
Like any technology, monolithic housing construction has its problems. First of all, weather conditions create some difficulties during production structural elements, especially when negative temperatures V winter time. The chemical activity of the water contained in the solution leads to hardening of the concrete. Increasing temperature increases water activity; as temperature decreases, it decreases, which slows down the hardening process. During frost, water freezes and increases in volume, disrupting the structure of concrete and reducing its strength, and this, in turn, reduces the frost resistance and water resistance of the entire building. Therefore, it makes more sense to build a flooded house in the summer, when the air temperature is more stable.
This technology requires the involvement of professional craftsmen. Yes, and ourselves technological processes(installation of reinforcement, installation of formwork, pouring concrete) are very labor-intensive and expensive (when compared with masonry work). In addition, the process of pouring concrete is lengthy; it takes 28 days to completely harden. At the same time, brick is more expensive than concrete, especially since it is possible to reduce material costs using self-cooking concrete mixture. Hence the conclusion: the construction of a poured house will cost more than the construction wooden log house, but cheaper than erecting a classic brick structure.
Undeniable advantages
Using this technology, the interior spaces can be planned without focusing on load-bearing walls, since the outer walls are load-bearing. Can be done different heights ceiling in different rooms, use wide interior openings or arches, form any curvilinear shapes, which allows architects to create unique images of buildings. There are practically no seams on monolithic walls, hence the absence of problems with their sealing. As a result, increased sound insulation and dust resistance. Because load-bearing frame able to withstand various loads, it is possible to erect buildings of various heights and purposes.
Since concrete is a good conductor of heat, poured houses take a long time to warm up. Using external insulation, you can not only eliminate this problem, but also turn it into an advantage: by accumulating heat in your walls, it will cool for a long time and keep it cool in the summer. Until now, only adobe buildings had this ability.
The advantages of monolithic construction technology include its durability (engineering calculations prove a 150-year service life) and the absence of risks of collapse due to the fact that the load is distributed evenly over the entire building frame. Among other things, concrete is non-toxic and safe for humans.
Concrete-based houses are famous for their strength and durability. The quality of such a building is significantly superior to that of any other building material, be it brick or wood. In the past, only industrial buildings or multi-storey residential complexes were erected on a concrete basis. Today, most people building their own home are increasingly turning to this house-building technology.
A house made of concrete is a durable, warm structure that does not require the purchase of expensive equipment and materials.
Currently, the idea of building a house from concrete has gained wide popularity in our country. For this reason, land owners planning to build private house or a cottage, they want to get acquainted with the construction technology in more detail in order to build a concrete house with their own hands. In addition to strength and durability, such a structure will not require expensive building materials. The construction of a concrete building is not a labor-intensive process when compared with structures for which brick is used.
A concrete house can be finished and decorated with any material, and its walls can be insulated with a heat-insulating layer during construction. This is due special technology permanent formwork. Below are several methods of building a concrete house with your own hands, which include the above technology.
Pros and cons of concrete-based buildings
Technical characteristics of concrete of different grades.
Concrete buildings have both advantages and disadvantages. Among the advantages, one can note a high-strength cast frame, which increases the durability of the structure in the event of exposure to phenomena such as seismic activity, close proximity groundwater and precipitation, which has a destructive effect on the structure of the structure.
The structure is devoid of joints, which are ubiquitous in buildings constructed from other materials. Heat energy is released through the joints, which leads to increased material costs during the cold season. A monolithic structure does not have this drawback.
A concrete house can be built on any type of soil layer; in addition, the construction of the structure can be carried out under any weather conditions. The construction of such a house can be completed in short terms, concrete will cost much less than other building materials, such as brick.
A concrete structure does not reduce reliability if the structure is uneven. When sawdust, expanded clay and perlite are added to the solution, there is no need to pour a massive foundation, since the walls of the house become lighter.
If the house is built using permanent formwork, there is no need for a separate thermal insulation layer. In addition, this will reduce the thickness of the walls.
To work with concrete you will need a number of tools.
Concrete walls are characterized by high noise insulation, which is achieved due to solidity. And the ceiling between floors can be constructed from various building materials.
Since the building is evenly spaced, microcracks and cracks will never appear in it.
Concrete houses also have disadvantages, but they are much fewer. When building the upper levels of a house, it is impossible to do without a special pump for concrete mortar. Laying concrete slabs as interfloor slabs is a rather labor-intensive process. This procedure will require high-strength scaffolding.
If the permanent formwork method was chosen, in the future it will be necessary to arrange supply and exhaust air exchange. Otherwise, there is a possibility of increased humidity, which will lead to the formation of mold and deterioration of building materials. The formwork must be plastered, as it is a flammable material that emits harmful substances when burning.
Concrete structures must be grounded. This is due to the fact that in the structure monolithic slabs There are iron pins.

Building a concrete house with your own hands
Scheme of removable formwork for the construction of walls.
As mentioned above, the construction of a concrete house can be carried out using two methods: permanent and removable formwork. Each construction method has its own characteristics both during construction and during maintenance of walls and other elements of the building.
The removable type of formwork is calculated individually for each layout. The purpose of its arrangement is to perfectly replicate all the contours of the planned building. The main material for formwork is wood, metal or plastic.
The opening in the middle of the formwork walls is the actual volume of the final wall of the building. It is calculated by determining the lowest possible temperature in an existing region. The calculation also depends on the thermal conductivity of the monolithic wall. The walls of the formwork are fixed with nuts, studs and washers. To simplify the dismantling of the shields, after pouring the concrete solution, you need to put corrugated tubes on the studs. This will help protect them from direct contact with the mixture.
This formwork method allows for pouring concrete solutions with low thermal conductivity. Walls made in this way will be able to retain more heat energy inside the building, but their strength may decrease.
It is worth paying special attention to the reinforcing layer. To do this, either steel or plastic reinforcing networks are placed in the formwork. To increase the strength of the walls, you can supplement the structure with reinforcement lathing.
Filling the solution is carried out in several approaches. During 1 cycle, it is necessary to pour no more than 0.5 m of concrete. The next approach is done after the previous mixture has hardened. The concrete solution must be compacted with a deep vibrator, paying special attention to the end parts. As soon as the solution hardens, it is necessary to move the formwork in a higher direction. Filling is carried out in this way until the required height of the walls being erected is reached.
For structural strength, the wall is reinforced.
Finishing work and installation thermal insulation material can be carried out only after 1-1.5 months after pouring concrete, since the structure must be completely strengthened.
Materials such as mineral wool, foam plastic, warm plaster and extruded polystyrene foam.
In some cases, a thermal insulation layer is created on the basis of a well facade. To do this, you need to step back a little from concrete base and line another wall with hollow brick or stone. The resulting gap can be filled with any insulating material. It is worth remembering that this method of insulation has less durability compared to polystyrene foam and brick.

Such formwork can have a variety of designs: longitudinal, window-sill, above-window, corner. Fixed formwork has a similar structure to a children's Lego set.
This method of wall construction is very popular due to the built-in thermal insulation layer. After all, when arranging permanent formwork you can save a lot of money.
The advantage of permanent formwork is that it has built-in reinforcement and a thermal insulation layer.
After placing the waterproofing material at the base of the building, a foam formwork is placed on it, which is secured using special guides into the tongue and groove. This ensures reliable pouring of the concrete solution, preventing any leaks at the joining points.
The volumes of foam formwork are various sizes. If necessary, it is possible to order the required amount of material from a factory that specializes in the production of expanded polystyrene. The slabs have standard width 15 cm, where 5-8 cm is a layer of foam. This thickness allows you to hold room temperature indoors at 5°C outdoors without using a heating system.
In the process of pouring such formwork, it is prohibited to use any warm solutions. It is recommended to use only concrete mixtures. This is due to the fact that warm solutions have increased sensitivity to vapor permeability. This causes excessive condensation to form, leading to increased level humidity inside the house.
Upon completion of construction, there is no need to take care of the thermal insulation layer. All you need to do is cover polystyrene foam boards decorative finishing or cover the building with composite panels.

When a person thinks about building his own house, he has to solve two main questions:
- Select material for walls, partitions and ceilings;
- Decide on the layout and number of floors of the house.
Some materials, for example, brick or cinder blocks, allow you to create a house with any arrangement and even configuration of rooms. Others, such as logs or reinforced concrete products, with their dimensions affect both the size of the rooms and their configuration. In this article we will discuss how to build a house from concrete panels. Let us immediately make a reservation that most often such products are reinforced concrete.
Beautiful house made of concrete panels
The choice in favor of a house made of reinforced concrete is influenced by the presence of a reinforced concrete products plant (RCP) or a house-building plant (DSK) near the construction site, which produces parts for individual construction. You can, of course, use standard designs, but this will impose certain restrictions on the layout of the house.
Panels are different
The base of the foundation must be below the freezing level of the soil. It consists of a sand cushion on which reinforced concrete foundation cushions are laid. Foundation blocks (FBS) are mounted on them in a row, so that the surface of the top row is above ground level. Then the foundation is waterproofed, and floor slabs are installed under the floor of the first floor. After this, the construction of the walls of the house begins.
Organization of work
Even before you start designing a house made of concrete panels, you need to think about who and how will deliver them to the construction site, where they will be stored, and how they will be installed. This is especially important if the site is small and there are already buildings nearby. It is necessary to determine the place where the crane will stand, with which the structures will be installed. In the most cramped conditions, it should be positioned so that the boom reach is enough to install the panel on the opposite side of the building.
Various technologies for constructing houses are more or less popular, for example, houses made of timber are experiencing a real boom, brick or block masonry is consistently in the lead, but the monolith is still quite a rare phenomenon. However, on our portal there is positive experience in building houses using monolithic technology, which may be of interest to self-builders who have not yet decided on the choice of method for constructing their house. Consider:
- Technologies of monolithic house construction.
- What is the monolith made of and pouring technologies.
- Examples of monolithic houses of portal participants.
Monolithic housing construction
Initially, monolithic construction meant only the construction of structures made of reinforced concrete, since there was simply no alternative to a reinforcing frame and cement-based mortar with aggregates. When pouring, prefabricated formwork is used. Not so long ago, monolithic construction was widespread only in industrial quantities, for the construction of multi-story buildings, public buildings or production facilities. But gradually the technology began to spread into the private sphere, which is due to a number of advantages of monolithic houses.
Immelnikoff
In my opinion, the trick of monolithic reinforced concrete is as follows:
- thin load-bearing walls (120-140 mm);
- high strength of the entire building, hence safety;
- seismic resistance;
- fire safety (all electrical wiring is laid inside the formwork before pouring);
- good “air” sound insulation (shock insulation is poor);
- high heat capacity of the house;
- durability (100-150 years);
- stable geometric dimensions of the house - optimization of interior decoration;
- versatility - any, without restrictions interior decoration;
- psychological comfort from the knowledge that nothing in the house will collapse, that the insulation will not get wet, that no person will break through the walls, that the house is a real centuries-old fortress.
This is my list.
Of course, the monolith has its share of shortcomings.
jtdesign
This technology requires qualified builders and the presence of concrete plants in the area, so as not to transport concrete further than 50 km. It is also unreasonable to build without a detailed design (reinforcement diagram, formwork diagram). So this may be one of the obstacles to the widespread adoption of this type of private home.
But any material has disadvantages; it’s another matter that their number does not outweigh. A concrete mixer plus modifying additives - and you can fill it with self-mixed concrete. Ideally, any construction process requires qualified performers, but in reality, our craftsmen have repeatedly proven that self-builders will give many “pros” a head start, since they build for themselves. If you have the desire, you can learn anything.

Interested in monolithic construction on your own (without reference to deadlines) two-story house For permanent residence size 10x10 m. Considering different types monolith, but reinforced concrete is a priority. I will build it alone, slowly, step by step, in general, long-term construction, I have no experience in construction, but the most important thing is that I have the desire, and this is very motivating.
Varieties of monolith
If initially monolithic houses were only made of reinforced concrete, today there are variations on the theme - instead of DSP they use wood concrete or sawdust concrete, and instead of a reinforcement frame - wooden racks.
But the essence remains the same - enclosing structures are not assembled or laid out from individual elements, but rather are poured. As a result, monolithic, seamless walls of almost any geometric shape are formed, which frees up the hands of architects. That is, if the abundance of bay windows and arches during construction from block/brick/wood will significantly complicate the process, then when pouring special effort not required.
Since ordinary reinforced concrete turns out to be too cold, due to its high thermal conductivity and thin walls, foam concrete, polystyrene concrete or expanded clay concrete are used to do without additional insulation. In the first case, the thermal conductivity of the wall is reduced due to the formation of large quantity air pores due to foam, in the second - by adding polystyrene or expanded clay granules. But according to its varieties, the monolith is divided not by the type of concrete poured, but by the type of formwork - it can be removable or permanent.
Removable formwork
In the private sector, it is usually made of moisture-resistant or laminated plywood; boards, metal or plastic are less commonly used. The sheets are used whole or cut into pieces, depending on the scale of the fill. The elements are fastened together and, as they are poured, moved to a new location, since only specialized companies can afford to assemble the formwork for the entire house at once. And self-builders fill houses in stages, mainly horizontally. Plywood is deservedly popular, as it holds its shape well and allows you to get a smooth wall surface, and if it is also laminated, then the set can be enough for more than one construction site. As for fasteners, everything is individual.
alexxxxx
Plywood 12 mm thick, increased moisture resistance, 2500 × 1200 mm, cut in half lengthwise (600 mm), four ties per sheet (sheets were drilled through, folded together, 100 mm from the bottom), the top was tied together with bars. Ties with two jammed nuts at one end, 250 mm long, 8 mm in diameter, were lowered into the spindle. Driven nuts are driven into the formwork from the outside; you only need to turn it (with a screwdriver) from inside the walls.
Rearranging removable formwork as it is poured is considered one of the most labor-intensive and time-consuming processes, and the fewer operations required, the better.
Permanent formwork
Unlike the removable one, intended solely to give the filler the desired shape and dismantled after setting, the non-removable one remains in the “pie” and at the same time serves as insulation. These are hollow blocks or slabs with composite lintels, smooth edges or a grooved connection system. Fixed formwork is either entirely made of polystyrene foam, or combined - PPS as outer wall, and the internal one is from slab materials. There are also technologies for permanent formwork, where EPS is used only as insulation, and both walls are made of pressed wood chips. Such blocks are considered more environmentally friendly than polystyrene ones.
sasha_nik
I will note the main advantages and disadvantages of this type of permanent formwork, in my opinion, from the point of view of not a professional, but a consumer.
Advantages:
- Saving house space - wall thickness 32 cm.
- In terms of cost and speed of construction, it is no more expensive than, say, aerated concrete, 400 mm thick with insulation.
- The wall is monolithic - the most durable, in theory, the likelihood of its destruction, i.e., the formation of cracks, if the technology is followed, is practically excluded.
- Interior houses made of chip-cement slabs - the microclimate will be close to the microclimate of a wooden house.
- In interior wall It's easy to screw in screws, it's easy to make grooves for electrical wiring.
Flaws:
- Expanded polystyrene as insulation is a dubious drawback, taking into account the fact that, using EPS technology, it will be protected from external influences non-flammable materials. Whether it will fall apart in thirty years is also debatable and largely depends on the quality of the PPS itself and on the quality of work performed during construction. But this is the only thing that confuses me about this technology. Although many insulation systems are also based on polystyrene foam.
- The facade is made of chip-cement slabs - this drawback is easily eliminated by a protective hinged screen, decorative plaster or in another way.
The thickness of the heat insulation layer is selected depending on the region of construction, it starts from 50 mm, but on average 100 mm is enough if we are not talking about the northern regions. You can find out the exact figure by making a heat calculation, and based on the results, select suitable blocks or slabs.
Monolithic houses of portal participants

The walls were minimally reinforced (openings, corners and upper layers of floors along the perimeter, trimmings between layers). The concrete was mixed ourselves, proportions 1/2.5/3 (cement, sand, crushed stone). Crushed stone used fractions of 20-40 mm, I regretted a thousand times that I did not buy 10-20 mm, large ones are difficult to take with a shovel from a pile and it is much easier to bayonet concrete with a small fraction. It took two months with breaks for the main work (the slab was poured last year).
A house for permanent residence, the foundation is a regular slab, 15 cm thick, with ribs of 40 cm, backfilled with 30 cm sand, drainage around the perimeter. The slab was immediately filled with a heated floor contour, six branches (33 m each), water distribution to the bathroom and kitchen, and a sewerage system (grey drains).
The user's walls are 15 cm thick on the first floor and 12 cm on the second, lightweight floor slab (beams 15 cm, canvas 7-8 cm). It was not possible to finish it in one season, so the cast box spent the winter without a roof or insulation, but no cracks or other damage were found in the spring. In the new season, the project underwent changes, and the house acquired an extension using the same technology, but with the addition of a ready-made crushed stone-sand mixture to the concrete. Insulation with expanded polystyrene slabs on the facade (18-20 cm), expanded polystyrene crumbs on the attic floor (30-35 cm).
Our other craftsman - cprivetom, preferred with PPS as insulation for his one-story monolithic house.

We began construction of a house for a family of six - two parents and four children, a house for permanent residence. I had to tinker with the layout. We treat the house quite utilitarianly, the main thing is that you can live in it comfortably, and decorativeness is secondary. Therefore, the form is simple - without bay windows, tricky corners, ledges and turrets, the roof is gable, the facades are without decorations. Some say you have a “barn” style, but for us it’s a simple “ranch”.
The foundation is a slab, 30 cm thick, lying on a 10 cm layer of EPS, the slabs are laid on a compacted bed of crushed stone (5 cm), the crushed stone is laid on a compacted sand “cushion” (40 cm). The main communications – water supply and sewerage – were previously laid out in a layer of sand. The insulation was covered with glass insulation, a reinforcement frame was laid in two layers with reinforcement under load-bearing walls(step 125 mm), concreted with ready-made mortar.
