He built a house from fixed formwork. Fixed formwork made of expanded polystyrene for building houses

Nikolai himself is building a private house in Samara. He told us how to save space on a land plot with a width of only 12 meters, using universal ties for TECHNONICOL fixed formwork.

Background and technical data

Construction objects on the site: bath - 35 m2, house - 110m2.

Problem: the land plot is very small in area, you need to save every meter.

Solution: installation of the foundation, basement, walls of the bathhouse and a two-story house by the method of insulated fixed formwork using universal screeds to reduce the thickness of the foundation and walls.

Contractor: there is no contractor, hiring specialists for construction under their own management.

My name is Nikolay, I am a private developer from Samara. My building plot is quite small - only 12 meters wide. I know no more about construction than you do, but I decided to do everything with my own hands with the help of hired workers.

When choosing materials for building the foundation of a house and a bath, I relied on knowledge gained from various sources. And, interestingly, the arrangement of fixed formwork using universal screeds was not initially discussed at all. Just to insulate external surfaces, I purchased XPS TECHNONICOL CARBON ECO extruded polystyrene foam, and screeds came in addition to it. After reading about the properties of ties and how to install them, I decided that this would be the best choice in my case.

Why did you choose fixed formwork?

Just imagine that without fixed insulated formwork and universal ties, I would have to build walls about 1.2-1.5 m thick and lay a very strong and more expensive foundation. Our winters are frosty and a smaller wall thickness would lead to greater heat loss and energy consumption. Or, in an attempt to save on energy spent on heating, my family would live in a cold, damp house. And with such a small width of the site, the wall thickness of 1.2-1.5 m is a lot!

It was necessary to find a solution to this problem. I chose monolithic construction with the use of insulated fixed formwork, in which TECHNONICOL universal screeds are used. This method made it possible to make the wall thickness half as much, and I left the saved space for arranging the terrace.

In addition, the method of installing fixed formwork with universal ties is very simple and significantly reduces the time spent on work. After all, what are universal screeds? These are fasteners that quickly and reliably connect the walls of the formwork sheets to each other. With their help, I reduced the time for arranging the bath and the foundation of the house by more than 2 times. This was facilitated by the fact that a combination of formwork and insulation was used - we did not waste time on thermal insulation of the foundation and walls.

True, at first it was unusual for my hired specialists. They, too, were not familiar with this method of laying and. We thought it would be very difficult and expensive. They held it in their hands like some kind of jewel. They could not figure out how to arrange it more conveniently, how to connect it correctly. It took almost two weeks for the first level of the foundation of the house - they worked out the laying technology. But, when we figured out the system for installing screeds, the work went very quickly. The bath, where the height of the monolith was 3.5 meters, took only 12 days!

Construction technology from fixed formwork

As it turned out, the laying scheme is quite simple:

1. formwork sheets installed;
2. fixed with ties for fixed formwork;
3. fittings installed; The material was prepared for the site www.site
4. poured concrete in a circle about 50 cm high, then vibrated the cement mortar;
5. waited for the layer to dry;
6. began installing screeds for the next layer, and so on in a circle.

It took us 3.5 weeks to build the strip foundation and walls of the bathhouse. I didn’t have to install any bulky wooden structures, spacers, etc., and then reinstall everything. And there are absolutely no complaints about the screeds. They perfectly hold the load, and, in addition, it was convenient for workers to install fittings. The main difficulty was that during the construction of the walls it was necessary to evenly set them in level. Also, with the help of fixed formwork and universal screeds, the strip foundation for the construction of the house was already poured and the basement was driven out, and I plan to build the walls using a different technology and insulate.

Another benefit that I appreciated is the savings on materials. Not only is it a formwork for construction, it is also an excellent insulation for the basement. No need to separately purchase and install insulation. With this fixed formwork, the manufacturer guarantees the absence of cold bridges in the finished structure, which is exactly what I needed. Especially for the foundation of the house.

My conclusion

Fixed formwork and universal ties are a reasonable and economical solution for private construction. Especially if you want to have time to build up over the summer. Do not just violate the terms of the instructions. It is necessary to make a fixed formwork for each layer according to the height of the simultaneous pouring, depending on the width of the tape, not higher. Before pouring another layer of concrete, let the previous layer dry so that it has time to gain the required strength.

The only difficulty was only at the beginning - the process of installing screeds was not easy due to lack of practice. But everything comes with experience. This technology will save you both budget and time. After all, the solution combines formwork and insulation. It turns out that you are simultaneously closing two construction processes.

The next stage in the construction of my house is the insulation of the facade with XPS boards. Then I will also buy roofing materials for the construction of the roof of the house and the bath.

Traditionally, for the manufacture of foundations and walls in monolithic concrete houses, concrete was poured into temporary formwork, which was removed after the concrete had dried. The construction technology using fixed formwork is an alternative to such construction. The formwork is made of polystyrene foam, which folds like Lego blocks. After the formwork is installed, reinforcement is installed, the formwork is leveled and concrete is poured into it. After the concrete has dried, throughout the life of the building, the expanded polystyrene works as an insulating material. It seems to be a very good technology for the rapid construction of a house. Lightweight formwork that does not need to be removed ensures virtually no waste. Buildings built using fixed formwork have increased strength and are positioned as energy efficient and environmentally friendly. But is the non-removable polystyrene foam formwork really that good?

First, about the environmental friendliness of polystyrene foam

It should be noted that expanded polystyrene with a very big stretch can be attributed to environmentally friendly materials. However, it is so often labeled. This is true, unless you consider it in terms of:

Effects on humans - styrene, from which expanded polystyrene is made, is a poison for humans, it is polymerized in expanded polystyrene, but not completely, so the poison is gradually released into the environment, and under the influence of light, oxygen, heat, etc. he starts to stand out more actively. In case of fire, it burns at a very high temperature of 1100 ° C, destroying even metal structures, and emits toxic substances. Of course, modern polystyrene foam is processed with flame retardants, so they talk about fire safety, but flame retardants are also not harmless to humans.

Environmental Impacts - At the end of its useful life, Styrofoam goes to landfill, but it will lie there for hundreds of years, poisoning the environment, because it has poor biodegradability properties.

Question: Is such an "environmentally friendly" material needed?

Alteration of the house from fixed formwork

Fixed formwork houses are difficult to reconstruct. It is necessary to carefully consider the design of the house and anticipate all possible necessary changes in the future. For example, to add a window or a door, you will have to cut a monolithic concrete wall, which is not at all easy and time-consuming. It is also important to take into account all communication systems in advance: electrical wiring, plumbing pipes, ventilation, etc., since after construction it will be difficult to carry out all these communications.

Insects or water can get into the walls

Block segments must be installed very tightly, otherwise the outer insulation of the wall can become an excellent place for insects to live and groundwater can seep into it. But this is partly a solvable problem, there are blocks treated with insecticide and protected from water. However, as a rule, such blocks are more expensive than conventional ones.

Need skilled labor

This construction technology is relatively new in Russia, so it is difficult to find qualified practicing builders who have fully mastered the construction method. It also raises the cost of construction as skilled workers are in demand and cost more.

Can only be built during the warm season

At temperatures below 0°C, concrete hardening practically stops; it must be poured at temperatures above 5°C. Also, in a hot period, it may be necessary to moisten the concrete with water.

High humidity in the house after construction

Immediately after the construction of the house, problems with high humidity can arise. The increase in humidity in the house is due to the fact that the concrete is still in the process of curing. After it has completely hardened, the level of air humidity can reach a normal level. You can use a dehumidifier to dry the air.

Thermos house

Walls erected in this way do not "breathe" well, since polystyrene foam has a low vapor permeability. Therefore, it is imperative to provide a forced ventilation system in the house.

Mandatory grounding and zeroing of the house

The use of metal fittings requires a ground loop and zeroing.

The technology of building a house from fixed formwork has obvious advantages, but it also has a number of disadvantages, which are mostly associated with the use of polystyrene foam. If, when choosing a technology for building a house, take into account not only the speed of construction and cost, but also other factors, then the technology using fixed formwork will not be the best choice.

What is the best thermal insulation? Assessment from the point of view of environmental friendliness How to choose eco-friendly wallpapers. What to look for and what to avoid

Today, the construction market presents a large number of construction technologies available to almost every developer. Any buyer will find something that fully meets his needs. Fixed formwork has become one of the novelties that complement block, stone or brick housing construction options.

What is fixed formwork and where is it used?

formwork- these are separate elements in the form of slabs or blocks, assembled into a single frame structure, which acts as a form for laying a monolithic reinforced concrete sheet.

In construction, two types of formwork are used: removable(this design is disassembled after the concrete has completely hardened) and fixed.

Fixed formwork has two main differences:

1. As the name implies, it is not removed after the concrete mortar has set.
2. A similar frame for pouring concrete is made using a heater (most often polystyrene foam). Thanks to this design, houses under construction receive additional insulation even at the stage of wall construction.

Fixed formwork technology is versatile, suitable for both private and multi-storey construction.

In the construction process, the use of a fixed frame is used:

• during the construction of the foundation;
• during the construction of the walls of the building;
• when carrying out certain types of finishing work.

Currently, this design allows pouring a wide variety of shapes and designs from concrete. Fixed formwork is used for the foundation, the construction of arches, columns. And the presence of a heater in the frame increases the thermal insulation of monolithic concrete walls and allows you not to carry out insulation during finishing work.

Varieties of material for the frame

To date, there are several types of fixed formwork, each of which has its own fundamental assembly features and functional characteristics.

Here are the types that are most popular for suburban housing construction:

• is assembled from two parallel foam plates, the rows are superimposed on each other and fastened together with the help of spikes and grooves located along the edges of the panels. Additional structural strength is betrayed by iron fittings installed inside the structure. Currently, non-removable formwork for the foundation of expanded polystyrene is most often used, its price is usually low, which adds to its popularity.

• Facing (decorative) formwork. Special prefabricated modules, consisting of facade cladding plates, inside of which insulation and fittings are laid. Such a frame does not require any insulation or finishing.

• Wood concrete formwork implies the use of wood concrete slabs for the frame (panels consisting of wood chips mixed with concrete mortar). This design has higher thermal insulation performance than the polystyrene frame, however, the price of such formwork is very high, so it is used less often than others.

Advantages and disadvantages of technology

The use of fixed formwork technology in construction allows you to get a lot of advantages:

• Acceleration of the construction process. Assembling the formwork does not take much time, which means that the total time for erecting walls is also reduced.
• Possibility of monolithic construction at air temperatures below zero. It is possible to pour concrete into a frame with insulation at temperatures up to -10 C, while ordinary concrete work at low temperatures is impossible.
• Reducing the overall weight of the building leads to the possibility of reducing the cost of the foundation (using a lighter foundation for construction).
• No need for heavy construction equipment significantly simplifies and reduces the cost of construction.
• Increasing performance sound and heat insulation of the building.
• Extended service life monolithic structure.
• Facilitate finishing work.
• Possibility of hidden installation of utilities. All communications can be built into the frame and brought out in the required places through special holes in the formwork.
• Absence of biological and natural threats(buildings do not rot, do not become moldy, unattractive to rodents and insects).

Of the most serious shortcomings in most cases, note:

1. The need for interior and exterior decoration(an exception is formwork made of cladding panels).
2. Poor vapor permeability of the insulation, therefore, houses require the installation of high-quality forced ventilation of the room.
3. The need for grounding at home because of the iron reinforcement inside the walls.

Some features of the construction process

Foundation construction. Since houses with fixed formwork are relatively light in weight, they do not require a heavy foundation. A tape-type base with a slight indentation is usually used.

Shallow strip foundation - the basis for the house in the form of a concrete strip, buried in the ground by 20-30 centimeters, which runs under the load-bearing walls and around the entire perimeter of the building.

However, the choice of the foundation depends not only on the features of the structure being built, but also on the specific conditions of the area (soil quality, air humidity and many other factors).

When applied fixed formwork made of expanded polystyrene for the foundation it is also worth considering the need for additional waterproofing of concrete, because polystyrene foam has high moisture absorption rates and does not protect the concrete inside the frame from the damaging effects of moisture.

Finishing work. The fixed formwork technology allows the use of any finishing materials, both inside and outside the house. It is only necessary to remember that the temperature during the work must be positive. Materials are applied directly to the surface of the frame.

Fixed formwork prices

When determining the cost, it must be taken into account that the fixed formwork is a prefabricated structure, which means that the cost of building a monolithic house or foundation will depend on the construction area. In addition, it is worth considering the type of frame used.

Prices for elements of fixed formwork made of expanded polystyrene are presented in the table:

Depending on the material from which the fixed formwork for the foundation was made, the price can vary significantly. For example, the cost per 1 m2 of a polystyrene foam frame can reach 3 thousand rubles. Almost all companies that use a similar frame in the construction of houses offer services for calculating the cost based on the submitted project of the future house.

Video description

Fixed formwork- a relatively new way of erecting monolithic buildings. It, like any building technology, has both advantages and disadvantages. Only by studying all the pros and cons of this method of building a house, you can make the right choice.

If you want to know about fixed formwork houses, then read the text of this article.

Information about fixed formwork houses

Houses created from fixed formwork are sometimes called thermal houses. During the construction of such buildings, panels and blocks made of expanded polystyrene or materials similar to it are used.

These blocks or panels are assembled into a single frame, making it an excellent mold for pouring high quality pre-mixed concrete.

After the concrete hardens, the formwork frame firmly adheres to it and turns into a single monolithic structure.

Work on the creation of polystyrene formwork and pouring concrete takes a relatively small amount of time, so the term for the construction of thermal houses is short.

The advantages of this technology of building houses:

• fast construction time;
• ease of creating a frame for future buildings;
• the use of low cost materials;
• the possibility of erecting buildings without the use of powerful lifting mechanisms;
• the ability to work in various temperature conditions (up to -10 degrees Celsius);
• no need to prepare the outer walls of the building for finishing work;
• excellent heat saving;
• the possibility of trouble-free division of polystyrene foam blocks into parts to form buildings of various configurations;
• long service life of the erected building (up to one hundred years).

Listing the advantages of structures created on the basis of expanded polystyrene, it is impossible not to mention their disadvantages:

• relatively high fire hazard;
• the danger of destruction of polystyrene walls in contact with various solvents and gasoline;
• weight load restrictions (no more than seventy kilograms per load-bearing wall);
• possible presence of moisture in the house.

Pay attention to the fact that expanded polystyrene is a conditionally non-toxic material, however, with a large heating of its surfaces (at temperatures above ninety degrees Celsius), it can release substances harmful to humans.

Many of those who use polystyrene panels and blocks for the construction of residential or outbuildings believe that the advantages of such structures far outweigh their disadvantages.

If you want to join the number of owners of thermal houses, then before starting construction, consider the information received and weigh all the pros and cons, and only after that proceed with the development of the project.

Building a house from fixed formwork does not take much time. Moreover, you will spend most of it not on the formation of walls, but on preparatory and final finishing work.

More about projects

Projects of houses from fixed formwork are quite popular. People who decide to build a polystyrene foam structure understand that this construction technology will help them save money on the purchase of building materials.

It is worth noting that houses created on the basis of polystyrene foam plates or blocks have high strength and are in no way inferior to standard brick buildings in this indicator.

The project of a house built using fixed formwork does not limit a person in any way.

As mentioned above, this material is easy to cut and can be assembled into various - both classic and very unusual designs.

Having decided to build a house based on expanded polystyrene, you can create exactly the layout of the premises that you dreamed about.

At the same time, you can make changes to the project not only at the stage of its approval, but also at the construction stage, when you do not like this or that format of the room.

The Web presents a large number of house projects that can be created from polystyrene foam.

You can repeat any of these projects exactly, focusing on the size of rooms and other premises, or you can make certain changes to it in order to find a house created exclusively for your needs.

Expanded polystyrene is a malleable material that is easy to work with sharp knives or saws. Using these items, you can give the material any shape you want.

The average thickness of the walls of a house built from expanded polystyrene is twenty-five centimeters.

The thickness of the walls of a house built of brick can reach up to sixty-five centimeters. At the same time, the indicator of the level of heat saving for these houses will be the same.

Therefore, using expanded polystyrene for the construction of a building, you can increase the usable volume of each room of the house by at least thirty centimeters from each wall.

The owners of expanded polystyrene houses are also pleased with the fact that they can use absolutely any materials as decoration for their buildings.

If you are a fan of the classics, you can cover the styrofoam with a layer of protective film and overlay it with a single layer of brick to create the appearance of a solid brick house.

You can use treated wood and decorative stone panels for the same purpose.

Lovers of simplicity and modernity can decorate a house made of polystyrene foam with metal or plastic siding.

Remember that during the finishing work you will not need to use additional materials used for wall insulation.

A house built on the basis of expanded polystyrene retains forty percent more heat than a classic brick house of the same configuration.

Expanded polystyrene technology

A material called Styrofoam was created in the second half of the twentieth century by German scientists.

After they studied its properties, expanded polystyrene began to be used in the construction of new buildings and in the insulation of existing houses and public facilities.

Initially, only expanded polystyrene plates were produced, but over time, factories began to create blocks of this material, hollow inside, making it possible to simplify the process of pouring them with concrete.

For the convenience of assembling blocks and plates made of expanded polystyrene, manufacturers equip them with special fasteners that allow them to be assembled into a single structure.

To start building a house created on the basis of fixed formwork, you should purchase the required number of panels and blocks made of polystyrene foam and assemble them into a single structure.

After the structure is assembled and fixed, it should be poured with prepared concrete mortar and wait for it to solidify completely.

Concrete is a popular material known for its thermal conductivity and high density.

If you are building a house from Styrofoam in a cold climate, you can neutralize this minus of concrete by pasting over the outside of your building with an additional layer of insulation, for example, with cotton wool.

For buildings built in temperate climates, a layer of concrete and a layer of polystyrene foam, combined into a single structure, will be more than enough.

Expanded polystyrene is rightfully considered an excellent heat insulator, as it has a low level of heat conductivity.

What buildings can be built using expanded polystyrene?

In fact, many

• dachas, cottages, private houses;
• low-rise multi-apartment buildings of the cascade type;
• houses with a large number of storeys;
• utility rooms or rural buildings (for example, chicken coops, animal pens, etc.);
• various sports facilities (including indoor tennis courts, gyms, swimming pools, ice arenas, etc.);
• public spaces for various purposes.

It is possible to reduce the fire hazard of this material by using special layers that protect polystyrene foam from possible ignition.

Pay attention to the fact that the thickness of such layers must be at least thirty millimeters.

How to build a house from Styrofoam?

The construction of a polystyrene foam structure resembles the construction of houses that are built in accordance with reinforced concrete monolithic technology.

The basis of such a house are polystyrene blocks with standard sizes.

As a rule, the sizes of blocks that can be bought in modern construction markets are one hundred centimeters long, twenty-five centimeters wide and twenty-five centimeters deep.

Each of these blocks is equipped with a special locking mechanism that allows you to assemble them into single structures, as if playing Lego.

The structure assembled in accordance with the project will be the actual walls of the building. Expanded polystyrene blocks have special cavities inside, into which concrete should be poured.

To increase the reliability of such a design and make it static, during the installation of walls made of expanded polystyrene, special metal reinforcement is placed inside them.

The diameter of this reinforcement can be different: the higher the number of storeys of the building, the stronger and more voluminous it should be.

After the installation of the reinforcement is completed, the resulting structure is temporarily fastened with a special tie wire, which allows it to remain static. Concrete is poured into polystyrene foam blocks at this stage of the construction of the house.

If you complete all the initial stages of building a house from this material in full accordance with the technology of its use, you will receive a guarantee that the created frame will easily withstand all the necessary concrete floors that have a solid weight.

The maximum number of storeys of a building created from fixed formwork should not exceed nine floors.

That is why not only private low-rise buildings, but also apartment buildings are often built from this material.

Modern polystyrene foam blocks are made from granular material and undergo specialized factory processing, which makes it possible to increase its fire resistance several times.

The undeniable advantage of expanded polystyrene is the fact that, unlike many other materials created in chemical laboratories, it has no smell.

As mentioned above, the exterior finish of polystyrene foam structures can be any. This also applies to interior decoration.

If you want to build your house from this material, you can cover its walls from the inside with a thick layer of plaster, tiles or drywall.

After reading this article, you were able to learn about the specifics of houses built from polystyrene foam materials.

If you are interested in this topic and want to build a house from fixed formwork, then carefully consider all the pros and cons of this design, and only after such an analysis make a decision on construction.

Fixed formwork is a special design. The technology of building houses with its use has become quite widespread today, and this is no coincidence. Practice has shown that fixed formwork house- this is one of the most affordable types of building your own housing, which is distinguished by reliability, economy and ease of construction of the entire structure - building a house using this technology is comparable to the process of assembling a designer.

The essence of the technology is to assemble a single structure, that is, pre-installed blocks with special voids are assembled into grooves, reinforcement is laid on the lintels. Further, all cavities are filled with cement of a high grade of strength. Thus, the result is a monolithic reinforced concrete wall, insulated with polystyrene foam.

The construction of fixed formwork gives the result of a solid structure that does not require additional insulation. Quickly, economically, and most importantly - inexpensively.

The price of building a private house from fixed formwork is from 13,600 rubles per m 2

Stages of building a house from fixed formwork

Let's briefly consider the main stages of building a house from fixed formwork. There are six main steps in total:

1. Project selection- the most important stage, since the house is not built for one year, then the choice of layout and auxiliary factors should be approached very responsibly. Despite the fact that the construction of fixed formwork allows you to build houses up to 16 floors, it is low-rise buildings that are most widespread. Since expanded polystyrene can be easily processed, almost any design can be obtained. This makes it possible to build complex architectural forms from fixed formwork. A fixed formwork house can have various configurations, almost any layout, and includes the possibility of redevelopment, for example, adding some elements.

2. Foundation construction. The type of this construction is determined by the features of the construction of the house, the characteristics of the local soil, the level of groundwater and other factors. A fixed formwork house can be erected on a strip, columnar and precast concrete foundation. The most widely used strip foundation, as the most simple and reliable design. The depth of laying the foundation is approximately one and a half meters, below the level of soil freezing. This requires thorough earthworks, which increases the cost of building from fixed formwork. If you want to save money, you can equip the foundation without a basement. The savings will be 15% of the total cost of construction, while using a prefabricated strip-type foundation. For this type of house, waterproofing is mandatory.

3. After the foundation is ready, you can proceed to wall construction. Note that this process is as simple as possible and includes three main loops:

• - Installation of blocks;
• - Reinforcement;
• - Cementing.

The first row is attached to the foundation by vertical reinforcement. Further, according to the project, the houses begin to lay bars in the grooves of the blocks along the horizontal level. The same bars will be connected to the vertical reinforcement by twisting. The second row of blocks is laid by overlapping, which will create a solid and reliable structure. Cementing is done every two rows of blocks. Since expanded polystyrene has a high coefficient of thermal resistance, the walls can be quite thin, and additional insulation is not required. There will be significant savings on the material.

4. Stage communication includes a number of processes that are directly related to the previous ones. The project initially laid down the schemes for conducting communications to the house, while both during the construction of the foundation and during the construction of walls, these facts must be taken into account. The supply of water and gas pipes, electrical cables and other communication elements is carried out in conjunction with the construction of walls, where special inputs are equipped. All main communications can be laid inside the formwork - no boxes are required.

5. Stage exterior finish necessary, since polystyrene blocks have an unaesthetic appearance. For exterior decoration, you can choose almost any material, such as siding, natural stone, plastering with decorative types of plaster and many others - everything is limited by imagination and financial capabilities.

6. Interior decoration is a long and costly process. It is also determined by the financial capabilities of the owner of the house. The smooth surface of the blocks can significantly save on some finishing work. Walls can be plastered, painted or wallpapered. The type of finish is selected from your own preferences.

Features of fixed formwork houses

So, we have already found out: what are the main stages of construction from fixed formwork. The main process includes the erection of walls. This is done strictly according to a certain technology. The basic principle of masonry is the displacement of each new row. The connection of polystyrene foam blocks is carried out with a slight pressure on the edges, due to which special locks are interconnected tightly and reliably. It is worth noting that the most important is the third row, which serves as a reference indicator for the alignment of the blocks along the vertical seams. After the formwork is built, the voids are cemented.

Pouring concrete in fixed formwork has its own characteristics. It is worth starting cementing from the corners, moving towards the center. This will help avoid the formation of air bubbles. A monolithic structure must be very durable. To achieve this result, it is desirable to use concrete of a strength grade of at least M200. For additional strength, gravel backfill is used with a gravel fraction of no more than 20. All pouring is done using a concrete pump. Also, construction from fixed formwork includes bayoneting - this is the process of compacting concrete (it is also carried out to remove air bubbles and more evenly lay layers). The solution is poured no more than two or three rows, while the surface is not leveled. This is necessary so that the new layer adheres better to the previous one. Note that the construction of simple walls and walls that have complex structural elements or ledges are erected equally quickly. The labor intensity does not change, while the finished house from fixed formwork will have any desired configuration.

Construction of a cottage from fixed formwork allows you to achieve significant savings in further operation. Since its heating does not require significant costs, the costs will be significantly reduced. This is due to the properties of expanded polystyrene, the material perfectly retains heat. Note that while saving on both materials and heating the house, the house will have a larger internal area, because the walls are thinner than those of a brick or other house. That is why the technology of fixed formwork is gaining more and more popularity. The effectiveness of the formwork has justified itself from a practical point of view, while the process does not include the dismantling of the formwork - the entire structure is completely monolithic. It is this fact that determines all the properties of the house from fixed formwork.

This technology is the most promising direction. In fact, it is a quick construction of a house. During construction, special tools are not required, ordinary saws, knives, shovels and containers for mixing concrete are enough. Since the blocks are very light, the walls can be built completely independently. However, this is not worth doing, since knowledge of the process is still necessary. Some unaccounted for nuances can lead to disastrous consequences. Best of all, if the house is built by professionals, the resulting housing will serve you for decades.

Building a house from fixed formwork is a reliable and fast way to get a modern, beautiful and economical home. The cost of such a house is much less than that of a brick one. The number of storeys of your house can be any, since polystyrene blocks allow you to get a fairly high house. If necessary, the house can be equipped with: a terrace, an attic, any complex architectural elements, such as a bay window and many other elements. A fixed formwork house can be reconstructed and improved, for example, by adding a terrace.

Advantages of fixed formwork

So, we found out that the technology of fixed formwork is quite simple and does not require capital investments. Let us point out some positive aspects of this technology.

Main advantage- This is the speed of building a house. In just 5 days, you can completely build walls! Such results with other technologies are unlikely to be achieved. Despite the fact that the polystyrene foam blocks are very large, their weight is relatively small. Due to this, the process of building walls is simplified as much as possible.

Further, one can note the high variability of the configuration of the walls. Styrofoam blocks can be easily processed, while some non-standard elements are already coming from the factory. This allows you to create any individual project at home to suit your needs. You can think of additional utility rooms or bathrooms. In addition, you can choose different floor options, that is, it is not necessary to make a monolithic floor, for example, you can equip either a wooden or prefabricated floor, reinforced concrete beams are also suitable.

Let's highlight some more advantages:

• - Low thermal conductivity of the walls. Home heating does not require significant costs;
• - Expanded polystyrene blocks do not absorb moisture and have high vapor barrier properties - such a house "breathes";
• - High sound and noise insulation properties make the house comfortable and protected;
• - The concrete with which the walls are poured is a symbol of strength, reliability and durability;
• - Unlimited architectural and other solutions used in the construction of the house, allow you to embody the most daring ideas and fantasies;
• - Rigidity and strength of the structure, which over time gives a minimum drawdown. The load is evenly distributed on the foundation base.
• - The service life of the house is not less than 100 years!

This is just a small number of advantages that are inherent in the construction of fixed formwork. It can also be noted that houses of this type are earthquake resistant. The operational properties are characterized by the frame structure, where there are no voids or "cold bridges". In addition, the formwork is resistant to aging and wear, temperature changes and other weather influences. In general, the construction of a house has a short time frame, since the construction scheme is clear and well-established, and has long established itself in practice. Each stage includes savings: monolithic walls are lighter than brick ones, so a solid foundation is not required; the walls are immediately insulated; since the walls have the correct geometry, they do not need to be leveled.

Disadvantages of fixed formwork

When building from fixed formwork, it is required to pay a lot of attention to the preparation of the concrete mixture. It must have a homogeneous mass. Additionally, you will have to check the brand of strength. If you choose low-quality concrete, then the walls will subsequently be less durable. It is also necessary to monitor the correct laying of the reinforcement.

Main difficulty when erecting walls from fixed formwork, this is a high-quality compaction of the concrete mixture. If these works are performed poorly, then "shells" may form in the wall, which will also affect the strength of the finished structure. This is unacceptable, as this will lead to the "floating" effect of the formwork. The last row of masonry requires special attention and a professional approach. The entire load from the roof will be perceived precisely by this row. It is important to equip the walls as vertically and rectilinearly as possible. Construction from fixed formwork requires the arrangement of scaffolding and special fasteners, which will determine the verticality of the walls and provide direct access to the height. It is unlikely that you will be able to do this on your own. Nobody needs a crooked house, so it is necessary that the construction be carried out only by professionals in this field.

When building walls, as we noted above, special tools are not required, however, some elements, if used correctly during construction, are aimed at speeding up and simplifying the process. Difficulty is also noted in the arrangement of door and window openings, as well as corner openings, when making bay windows and other architectural forms. In this case, a professional approach of specialists is also required.

It is worth noting that the level of the walls directly depends on the level of the foundation. If the foundation is made poorly, then the walls will "float". If the walls are uneven, then it is impossible to compensate for the defect with the thickness of the solution - the house will have to be dismantled to the level of the foundation and rebuilt again. It is very costly both in time and money. Wall modules are sometimes additionally glued to achieve the desired strength. It also makes adjustments to the expense item.

As for the environmental friendliness of the material, it cannot be called one hundred percent, since liquid glass has its drawbacks. This requires the construction of mandatory ventilation in the house. Also of the shortcomings can be noted, the obligatory external decoration of the walls.
