Wooden or brick houses rightfully have an army of fans. But despite all their advantages, they have one very significant disadvantage - their construction cannot be called quick. For those who are thinking about building own home, but at the same time does not have enough time in reserve and cannot boast of great knowledge in construction, all that remains is to choose monolithic method housing construction. The article will focus on houses from permanent formwork.
In order to fill the foundation and walls of such a house, formwork is used. It can be removable (that is, dismantled after completion of work) or non-removable. The second option remains in place after the mortar is poured and hardened, and all external finishing work is carried out directly on top of the formwork.

So, there is a foundation made in the most suitable way for the given soil. Most often it is a strip base. In any case, it is first covered with a layer of waterproofing material, and reinforcing rods are driven in.
Laying the fourth and subsequent rows
What can you use to make permanent formwork for your foundation yourself?
If home handyman If he has the strength to be precise, accurate and consistent in his actions, he will be able to make a permanent form for the foundation himself. You will need to choose from several options for suitable material:
All of them are quite durable, resistant to moisture, and elastic. The only indicator that these materials do not possess is thermal insulation. Therefore, you additionally need to purchase something to provide heat (for example, mineral wool). Still needed waterproofing material, fittings, components for cement-sand mixture, a set of coupling screws and nuts for fixing structural elements together.
Cost of building a house from permanent formwork
House made of permanent formwork: construction technology, Construction portal
If you want to learn about houses made of permanent formwork, then read the text of this article.
Houses made from permanent formwork are sometimes called thermal houses. During the construction of such buildings, panels and blocks made of polystyrene foam or similar materials are used.
These blocks or panels are assembled into a single frame, which becomes an excellent form 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.
The work of creating polystyrene foam formwork and pouring concrete takes a relatively small amount of time, so the construction period for thermal houses is short.
The advantages of this technology for building houses:
Listing the advantages of structures created on the basis of polystyrene foam, it is impossible not to mention their disadvantages:
Pay attention to the fact that polystyrene foam is a conditionally non-toxic material, however, when its surfaces are heated greatly (at temperatures above ninety degrees Celsius), it can release substances harmful to humans.
Many of those who use polystyrene foam panels and blocks for the construction of residential or commercial buildings believe that the advantages of such structures significantly outweigh their disadvantages.
If you want to join the ranks of owners of thermal houses, then before starting construction, consider the information received and weigh all the pros and cons, and only after that start developing the project.
Building a house from permanent formwork will not take much time. Moreover, you will spend most of it not on forming the walls, but on carrying out preparatory and final finishing work.
Projects of houses made from permanent 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 built on the basis of polystyrene foam slabs or blocks have high strength and are in no way inferior in this indicator to standard brick buildings.
The design of a house built using permanent formwork does not limit a person in any way.
As mentioned above, this material is easy to cut and can be assembled into various designs, both classic and very unusual.
Having decided to build a house based on polystyrene foam, you will be able to create exactly the layout of the premises that you dreamed of.
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.
Presented on the Internet a large number of house projects that can be created from polystyrene foam.
You can exactly repeat any of these projects, focusing on the size of rooms and other premises, or you can make certain changes to it in order to find a home created exclusively for your needs.
Expanded polystyrene is a malleable material that can be easily processed with sharp knives or saws. Using these items, you can shape the material into any shape you want.
The average thickness of the walls of a house built from polystyrene foam 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 level of heat saving for these houses will be the same.
Therefore, using polystyrene foam to construct a building, you can increase the useful volume of each room of the house by at least thirty centimeters from each wall.
Owners of polystyrene foam houses are also pleased with the fact that they can use absolutely any materials to decorate their buildings.
If you are a fan of the classics, you can cover the polystyrene foam with a layer protective film and cover it with one layer of brick to create the appearance of a solid brick house.
For the same purposes, you can use treated wood and decorative stone panels.
Lovers of simplicity and modernity can decorate a polystyrene foam house with metal or plastic siding.
Remember that during finishing work you will not need to use Additional materials, used for wall insulation.
A house built on the basis of polystyrene foam retains forty percent more heat than a classic brick house of the same configuration.
The material, called expanded polystyrene, was created in the second half of the twentieth century by German scientists.
After they studied its properties, polystyrene foam began to be used in the construction of new buildings and in the insulation of existing houses and public facilities.
Initially, only polystyrene foam plates were produced, but over time, factories began to create blocks from this material, hollow inside, making it easier to fill them with concrete.
For ease of assembly of blocks and plates made of polystyrene foam, manufacturers equip them with special fasteners that allow them to be assembled into a single structure.
To begin building a house based on permanent formwork, you should purchase the required number of panels and blocks made of expanded polystyrene and assemble them into a single structure.
After the structure has been assembled and fixed, it should be filled with prepared concrete mortar and wait until it hardens completely.
Concrete is a popular material known for its thermal conductivity and high density.
If you are building a house from polystyrene foam in a cold climate, you can neutralize this disadvantage of concrete by covering outside of its construction with an additional layer of insulation, for example, cotton wool.
For buildings erected in a temperate climate, 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 thermal insulator, as it has a low level of heat conductivity.
What buildings can be built using polystyrene foam?
In fact, many:
Reduce fire hazard of this material possible by using special layers that protect polystyrene foam from possible fire.
Please note that the thickness of such layers must be at least thirty millimeters.
The construction of an expanded polystyrene structure is reminiscent of the construction of houses that are erected in accordance with reinforced concrete monolithic technology.
The basis of such a house is polystyrene foam blocks of standard sizes.
Typically, the sizes of blocks that can be purchased on modern construction markets are one hundred centimeters in length, twenty-five centimeters in width and twenty-five centimeters in depth.
Each of these blocks is equipped with a special locking mechanism that allows them to be assembled into uniform designs like 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 structure and make it static, during the installation of polystyrene foam walls, 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 building a 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 significant weight.
The maximum number of floors of a building constructed from permanent formwork should not exceed nine floors.
That is why not only private low-rise buildings, but also multi-apartment buildings are often built from this material.
Modern polystyrene foam blocks are created from granular material and undergo specialized factory processing, which makes it possible to increase its fire resistance several times.
An undeniable advantage of polystyrene foam is the fact that, unlike many other materials created in chemical laboratories, it has no odor.
As stated above, external finishing polystyrene foam structures can be of any kind. 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 either a thick layer of plaster, tiles or plasterboard.
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 permanent formwork, then carefully consider all the pros and cons of this design, and only after such an analysis make a decision on construction.
If you want to quickly and cheaply build a house in the Moscow region, our builders will come to your aid. At modest prices, according to calculations, monolithic workers will build any house (or other structure) on your land plot in a short warm season. Services are provided only by specialists who have undergone special training.
The cost of building a house using permanent turnkey formwork for 1 m2 is 22,000 rubles. with materials.
Construction technologies using permanent formwork became widespread abroad about 15 years ago. In Russia they began to master it much later. The idea of the work is that there is no need for additional work by masons to remove formwork after hardening of monolithic walls.
The formwork serves not only as a frame, but also as thermal insulation, and sometimes external cladding walls The installation of permanent formwork does not require additional reinforcement: the reinforcement is placed in blocks in the factory.
The technology for installing permanent formwork is simple. The individual blocks are connected to each other using the simplest lock connections along pre-calibrated perimeters. Next, the permanent formwork is poured with concrete.
In the presence of quality solution The construction of the walls of the house by a team of four workers will take no more than two weeks. For the successful construction of walls and installation of partitions from permanent formwork, the most important thing is to carefully prepare the bed (the surface of the foundation or ceiling made of a monolith), accurately align the horizontal position along the line of filling the walls. The surface must be perfectly smooth to avoid waterproofing ruptures.
How to build a house in such a way that you don’t waste too much on materials and maintain high quality performance characteristics? Constructing the walls of a house from permanent formwork is an excellent solution for those who are not afraid of experiments and follow the latest developments in the world of construction technologies.

Formwork is a kind of form for a cement-sand mixture, which allows you to form the correct geometry of the walls. Builders use both removable/temporary and permanent/permanent formwork for the foundation. The second option allows you to save effort and time on dismantling work, as well as insulate and/or strengthen the walls, so it is increasingly used not only in industrial, but also in private construction.
Let's consider what properties permanent formwork should have.
Permanent formwork - important element energy efficient house
Advantages | Minuses |
---|---|
Ease of construction, the final result depends less on the skill of the workers (compared to homemade removable formwork). | In houses with permanent formwork it is often observed high humidity, which forces you to equip a powerful ventilation system. |
Good heat and sound insulation (compared to buildings made of brick and reinforced concrete slabs). | The impossibility of construction in the cold season, since a large mass of concrete hardens poorly at low temperatures. |
Ease of finishing work thanks to flat surface formwork without cracks and differences in wall thickness. | The need to additionally moisten the concrete during hot periods to prevent cracking of the walls. |
Reduced construction period compared to houses made of brick, stone, and gas blocks. | Buildings with metal reinforcement frames must be grounded as quickly as possible to avoid exposing people to the risk of lightning strikes. |
The durability of buildings with reinforced concrete formwork is 300 years or more. | Difficulty in dismantling during alterations and reconstruction, especially if fill reinforcement with metal rods was used. |
The technology is suitable for the construction of buildings of any size and number of floors, from summer houses to shopping complexes. | In case of fire, the formwork material can release harmful substances. |
Minimization of construction waste (compared to construction technology with removable formwork). | If the external treatment of polystyrene foam blocks is insufficient or incorrect, water, insects, and small rodents may enter the walls. |
To ensure uniform wall thickness, sheets of metal formwork are connected with metal studs
Metal formwork is one of the most expensive, therefore it is used mainly in industrial construction. It is made from sheets of aluminum or steel 1–2 mm thick on a metal frame and connected with anchors, plates or locks. The type and number of fasteners are calculated in such a way that when concrete is poured and hardened, the sheets do not bend either inward or outward.
When the formwork is made to order for a specific building, the manufacturer’s craftsmen themselves carry out a test assembly of the structure and only after confirming the suitability and completeness of all parts, the order is sent to the buyer.
Metal formwork has the most accurate geometry. Tolerance in parallelism of the sheet edges - no more than 2 mm over 1 m of product length.
In order to prevent premature oxidation and destruction of the metal due to contact with concrete and groundwater, sheets of future formwork are carefully coated with paint and lubricant in production. Often galvanized steel is also used, or the method is used powder coating, which forms a dense polymer film on the sheet. But if welding is used during installation (welding sheets to a frame or reinforcement to sheets), areas damaged by temperature will need to be re-applied. protective composition(lubricant, mastic, paint).
Powder coating of metal sheets is one of the most effective methods of protecting them from corrosion
Metal is well suited for buildings with complex geometries, since thin sheets can be easily bent at any desired angle, made into a curve or an arch. Finished walls They turn out very neat and smooth; if desired, they can be left without decorative finishing. Architects recommend using metal formwork in areas with complex loose soils.
To prevent concrete from leaking, the joints of metal formwork are connected especially carefully.
But experts also note some disadvantages of metal formwork:
Installation of aluminum sheets for wall formwork can be done by a couple of workers
Aluminum sheets with the addition of silicon, which weigh much less than steel sheets and do not require protection from the external environment, will help minimize labor costs for transportation and installation of metal formwork.
Reinforced concrete formwork blocks are recommended for large construction projects, at least a three-story private house. Since they have increased strength characteristics, in smaller buildings such a safety margin will be unnecessary. Thin-walled blocks are excellent for arranging the foundation of a permanent fence.
Reinforced concrete formwork blocks are installed offset
Reinforced concrete formwork blocks have the following advantages:
The best formwork is made from reinforced concrete blocks with indicators F75 (frost resistance), W4 (water permeability), 6% (water absorption), 350 kg/cm 2 (mechanical strength).
An example of the arrangement of reinforcement in formwork made of reinforced concrete blocks designed for two rods
The disadvantages of reinforced concrete blocks include:
Expanded clay concrete blocks do not have such disadvantages. Providing high strength of the walls, these analogues of reinforced concrete blocks do not require insulation of the house, since they already contain insulation - expanded clay.
For formwork, moisture-resistant plywood is most often used, but even then, this material is usually used to create a temporary form. After all, the service life and weather resistance of a laminated plywood sheet are an order of magnitude lower than the same parameters of a concrete wall.
Permanent plywood formwork is acceptable in the following cases:
In addition to questionable durability and strength, plywood formwork will require a lot of labor and careful handling. Since the sheets do not have a tongue-and-groove system and special joints, you will have to assemble the structure using self-tapping screws, additionally seal each joint and make an external sheathing with supports (so that the plywood does not bend). In addition, non-waterproof plywood swells and flakes from water, while laminated plywood repels the concrete mixture and never forms with it. monolithic wall, so it is very important to find a waterproof material with good adhesion.
Technoblock - an example of the successful use of plywood in formwork
Designation in the picture:
As a result, despite the cheapness and environmental friendliness of plywood, experts recommend using it only for temporary formwork. For permanent applications, it is better to use a technoblock - a composite product with an inner plywood layer.
Arbolite is a relatively new, but time-tested material. Formwork blocks from concrete and wood chips began to be made recently, but this mixture was used for floor insulation back in Soviet times. Arbolite blocks are much cheaper and lighter than reinforced concrete, so they are actively used in individual low-rise construction.
Some models of wood concrete blocks have a layer of insulation - stone wool or polyurethane foam
Compared to other types of permanent formwork, wood concrete blocks:
The disadvantage of wood concrete is its water permeability, so it is recommended to use it for the construction of walls on a ready-made waterproofed strip or slab foundation. The use of wood concrete for arranging the foundation is undesirable, since it will need to be very carefully protected from moisture.
An example of arranging formwork made of wood concrete and brick
Arbolite is produced in the form of hollow blocks and panels. In the second case, the panel serves only as the inner contour of the wall, and the outer one must be made of brick. The cavity between the materials is filled with concrete and reinforced, as when using other types of formwork. This option is more difficult to install, but ready house it turns out warm (arbolite), beautiful (brick) and durable (merging the strength characteristics of three materials).
When purchasing wood concrete blocks and slabs, pay attention to the eco-label, as some manufacturers use binders that are harmful to health (phenol, naphthalene). Be careful, plasticizer toxins can be released from the material even at room temperature.
Manufacturers of wood concrete blocks for formwork offer options for both high-rise buildings and small buildings. Be sure to consult with a consultant so as not to spend extra money on concrete for pouring thin-walled blocks or not to mistakenly take blocks with too small voids.
CSP (cement particle board) or sawdust concrete is another variation of a mixture of cement and crushed wood. It differs from wood concrete in the type of binder component and the addition of sand. Therefore, DSP is a denser, stronger and heavier material, and its thermal insulation is worse than that of wood concrete.
Cement particle boards can serve finishing material when covered with decorative mineral chips
Among the advantages of wood concrete formwork:
An example of creating reinforced formwork for a foundation made of cement bonded particle boards
European builders have been using permanent DSP formwork for more than 25 years, so there are many houses that confirm the durability and reliability of this material. Cement particle boards are well suited for both individual and multi-storey buildings, even in the harsh northern climate.
Profiled sheets, corrugated sheets or corrugated sheets have also found their use as permanent formwork, although much more often they are used for the manufacture of fences, roofs, and outbuildings. Important: profiled sheeting is only suitable for arranging composite slabs of interfloor floors and for large spans (from 5 m) it requires additional temporary supports. This material is not used for the construction of walls due to its small thickness, which reduces its resistance to mechanical loads in a vertical position.
An example of a floor design with a base made of profiled sheets
Builders are attracted to formwork made from this material with the following features:
To ensure good adhesion to concrete, choose special corrugated sheets with teeth for the formwork.
This is what it looks like interfloor covering based on corrugated sheeting from inside the building
Permanent formwork made from corrugated sheets is used mainly in industrial construction, as it requires construction metal frame buildings and metal beams ceilings It is not suitable for an individual home, as it will be unreasonably expensive.
Expanded polystyrene/foam is the most popular material for permanent formwork. Its demand is explained by factors such as:
Examples of polyurethane foam formwork blocks of different configurations
Opponents of polystyrene foam formwork point to its danger in case of fire and low degree of environmental friendliness. Even if you buy materials labeled eco, this does not guarantee that the formwork will not harm your health or the environment.
It is also important to keep in mind that foam formwork will be a good choice for buildings of simple shape, since the range of corner and rounded blocks does not yet allow satisfying all consumer needs.
Glass-magnesite sheets or FMS have been used as permanent formwork since the mid-20th century for the purpose of constructing thermally insulated houses. The material consists of a mixture of magnesium oxide and chloride, perlite, sawdust, fiberglass and polypropylene fabric. Not all components of glass magnesite are natural, but the finished composition is completely safe for people.
Different options for glass-magnesite sheets with decorative finishing
LSU - great option for the construction or reconstruction of a house with a weak foundation. Since the sheets themselves and those used for filling are lightweight concrete mixtures weigh much less than bricks, reinforced concrete blocks and others traditional materials, they do not load the structure of the building so much.
Among the advantages of glass magnesite:
If you plan to cut LSU boards on site, purchase spare jigsaw blades. This material wears out nail files several times faster than wood concrete and plywood.
Glass-magnesite sheets will be suitable for use at all stages of house construction
Glass-magnesite sheets, like arbolite sheets, often form only the internal contour of the formwork, while the external one is most often built from decorative brick. As a result, external finishing turns out to be unnecessary, and a thin layer of putty will be enough inside. The technology is suitable for the construction of houses up to 5 floors on a ready-made strip/slab foundation. In addition, it requires more time and effort than using polystyrene foam or DSP formwork (excluding decorative finishing).
Glass-magnesite sheets are currently produced only in China and Korea, and LSU quality control is also carried out there. There are no domestic analogues for this material.
We will consider the technology of constructing a foundation from ready-made hollow blocks using the example of lightweight concrete products. Unlike reinforced concrete blocks for high-rise buildings, these “bricks” can be installed by hand without a crane or manipulator.
The sand and gravel cushion must be covered with a thin layer of concrete before installation.
Thanks to the correct geometry of the blocks, the foundation strip is smooth and clear
At the junctions of internal and external walls you need to place special corner blocks
The blocks have special grooves for reinforcing rods
Pay attention to the location of the upper and lower rods in relation to each other, they should form a regular square
The reinforcement should be tied with an overlap of 15–20 cm
Install the second row of hollow blocks on top of the first
The concrete level should be slightly higher than the middle of the top row of blocks
Vertical reinforcing bars can be installed individually at a distance of 1.5 m from each other
New reinforcement is installed on top of the concrete screed
The foundation is ready for the construction of the walls of the future house
A foundation made of concrete hollow blocks for a private house using the described technology is installed by two workers in 2–3 days, taking into account the time for the first layers of concrete to set.
Comparison of costs for creating a foundation from full and hollow reinforced concrete blocks and monolithic with temporary formwork
A comparison shows that a foundation made of hollow concrete blocks is 18% cheaper than a foundation made of solid ones and 36% cheaper than a strip monolith poured using temporary wooden formwork. This is achieved by saving on the amount of reinforcement, reducing labor costs, the amount of concrete, etc. But constructing walls from reinforced concrete blocks will be too expensive (compared to polyurethane foam, wood concrete), it is better to use it only for the foundation.
Let's consider the process of creating permanent formwork from sheet materials with independent cutting using the example of EPS (extruded polystyrene foam).
You can cut sheets of polystyrene foam not only with power tools, but also with a hand saw
When laying EPS sheets in a trench, try to minimize the gaps
Plastic ties are easy to install by hand
Both metal and fiberglass reinforcing bars are suitable for reinforcement
Installed reinforcing rods must be tied with thin wire; welding is not allowed
We begin to increase the height of the foundation
Plastic spacers between the plates are installed in the same way
Protruding tails of ties can be easily trimmed with pliers
Filling the finished foundation with concrete
The upper plane of the concrete layer should be at the level of the outer layer of the formwork
After the foundation concrete has completely hardened, you can continue pouring the walls using the same technology, but such a foundation can also be used with other materials.
When giving preference to one of the options for permanent formwork, consider not only your financial capabilities and labor costs, but also its purpose. For example, in areas with swampy soil you should not use blocks based on wood chips, and in cold regions you should pay attention to a material with a minimum thermal conductivity coefficient. In this case, you can quickly build warm house without extra financial costs.
Nikolay himself is building a private house in Samara. He told us how to save space on a plot of land only 12 meters wide by using universal ties for TECHNONICOL permanent formwork.
Construction objects on the site: bathhouse - 35 m2, house - 110 m2.
Problem: land plot very small in area, you need to save every meter.
Solution: construction of the foundation, plinth, walls of the bathhouse and two-story house using insulated permanent formwork using universal screeds to reduce the thickness of the foundation and walls.
Contractor: There is no contractor; we hire specialists for construction under our own supervision.
My name is Nikolay, I am a private developer from Samara. My building plot of land is very 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 constructing the foundation of the house and bathhouse, I relied on knowledge obtained from various sources. And, interestingly, the arrangement of permanent formwork using universal screeds was not initially discussed at all. Just for insulation external surfaces I purchased extruded polystyrene foam XPS TECHNONICOL CARBON ECO, and ties came in addition to it. After reading about the properties of screeds and the method of installing them, I decided that this would be best choice in my case.
Just imagine that without permanent insulated formwork and universal screeds, 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 thinner walls 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 thickness of the walls is 1.2-1.5 m - this is a lot!
It was necessary to find a solution to this problem. I chose monolithic construction using insulated permanent formwork using TECHNONICOL universal screeds. This method made it possible to reduce the thickness of the walls by half, and I left the saved space for arranging the terrace.
In addition, the method of installing permanent formwork with universal ties is very simple and significantly reduces the time spent on work. After all, what are universal couplers? This is a fastener that quickly and reliably connects the walls of formwork sheets to each other. With their help, I reduced the time for arranging the bathhouse and the foundation of the house by more than 2 times. This was also 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 my hired specialists were unusual. They were also not familiar with this method of laying and. They thought it was very difficult and expensive. They held it in their hands like some kind of jewel. We couldn’t figure out how to position it more conveniently, how to connect it correctly. It took almost two weeks to work on the first level of the house’s foundation - they worked out the laying technology. But once we figured out the screed installation system, the work went very quickly. The bathhouse, where the height of the monolith was 3.5 meters, took only 12 days!
As it turns out, the installation scheme is completely simple:
It took us 3.5 weeks to build the strip foundation and walls of the bathhouse. There was no need to install any bulky wooden structures, spacers, etc., and then reinstall everything. Moreover, there are no complaints at all about the screeds. They hold the load perfectly, and, in addition, it was convenient for the workers to install the fittings. The main difficulty was that when constructing the walls it was necessary to level them evenly. Also, using permanent formwork and universal screeds, the strip foundation for the construction of the house, the basement was removed, and I plan to build the walls using a different technology and insulate them.
Another benefit that I appreciated was the savings on materials. Not only is this formwork for construction, it is also an excellent insulation material for the basement. There is no need to separately purchase and install insulation. With this permanent formwork, the manufacturer guarantees the absence of cold bridges in the finished structure, which is what I needed. Especially for the foundation of a house.
Permanent formwork and universal screeds are a reasonable and economical solution for private construction. Especially if you want to have time to rebuild over the summer. Just don’t violate the terms of the instructions. It is necessary to make permanent formwork for each layer at the height of simultaneous pouring depending on the width of the tape, not higher. Before pouring another layer of concrete, allow the previous layer to dry so that it has time to gain the required strength.
The only difficulty was at the beginning - the process of installing the 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 both formwork and insulation. It turns out that you are simultaneously closing two construction processes.
The next stage in the construction of my house is insulating the facade with XPS slabs. Then I'll buy more roofing materials for installing the roof of a house and bathhouse.
