Construction country houses made from foam blocks is gaining momentum and becoming more and more popular. This is due to the good thermal insulation and structural qualities of foam concrete, as well as high speed masonry and ease of work. We'll tell you how to build country house from foam blocks with your own hands.
Construction of a house made of foam concrete
Features of the material
Foam concrete blocks are a relatively new construction material, which is obtained by molding foam concrete in the form of rectangular parallelepipeds of a certain size. Foam concrete is a type of lightweight cellular concrete and belongs to structural and thermal insulation materials.
The blocks have standard sizes 200x300x600 mm. It should be noted that manufacturers manage to maintain these dimensions quite accurately and, in general, produce geometrically the right products, which has a positive effect on the practice of their use.
The weight of the block depends on the brand of concrete used and ranges from 12 to 48 kg for wall parts and from 6 to 24 kg for partition elements. Moreover, the volume of one block is large enough to replace 12 - 14 bricks, taking into account the seams.
Advantages of foam concrete blocks:
- Low thermal conductivity (2 - 3 times lower than that of brick) ensures high energy efficiency of buildings and savings on heating;
- Precise geometry allows for thin seams, which also increases resistance to heat loss by reducing cold bridges in the masonry;
- The increased dimensions make it possible to significantly speed up the laying process and reduce the number of masonry mortar and the number of cold bridges;
- Low density and weight allows the use of lightweight types of foundations, resulting in reduced construction costs;
- The material can be easily processed - cutting with hacksaws, drilling, nailing and grinding with planes.
There are also disadvantages:
- Due to the capillary structure, the material is able to absorb moisture, therefore it needs façade cladding protective coatings or hanging systems;
- The strength of foam concrete is relatively low, however, sufficient for one-story and two-story construction;
- The masonry needs to be reinforced with steel reinforcement to provide the necessary strength.
Important!
The material is transported in pallets and plastic film, storage should be carried out indoors or under a canopy in film.
Stages of work
How much it costs to build a country house from foam blocks depends on your approach to the construction process.
The cheapest way is to work on your own, and for this we have prepared instructions:
- We are drawing up a project according to which we will dig trenches for. We install the formwork, lay the reinforcement and fill the structure with concrete grade M250 - M300. It is enough to deepen the walls by 60 cm, the height of the base will be within 40 cm, the width of the foundation walls should exceed the width of the house walls by 15 - 20 cm;
- We level the walls of the plinth if the total height difference exceeds 30 mm. We lay a double layer of roofing material on the leveled wall of the plinth to cut off capillary suction of moisture. We install 2 - 3 blocks in the corners, level them with a level and stretch a thread between them along outside at the level of the top edge of the block;
- Prepare the glue for laying foam blocks according to the instructions on the package, apply the solution using a dosing spatula under several stones, apply the solution to the end of the block, press the stone into the solution and move it to the corner block. We check the accuracy of the installation by level, adjust with a rubber mallet;
- Lay out the first row and wait two hours for the glue to set. Then we make two 20x20 mm grooves in the upper edge of the blocks at a distance of 60 mm from the edge, in them cement mortar We lay reinforcement with a diameter of 8 mm along the entire perimeter of the masonry. Next, the reinforcement is repeated after 4 rows and under window openings, above the supports of the opening beams and in places of increased loads according to calculations;
- Place the next row on a clean surface, also starting from the corners. We remove walls and build partitions from partition or wall elements;
- We install formwork, reinforcement along the entire perimeter of the walls and pour a monolithic concrete belt height 20 – 40 cm (determined by calculation);
- We cover the ceiling with slabs or wooden beams and build rafter system and do the roofing;
- We insert the windows and get started facade work . It is best to clad the house with a ventilated system - siding, panels or clapboard;
- Let's do interior decoration and communications liner.
Important!
Only high-quality autoclaved blocks should be used, as they practically do not shrink and are more durable.
Build a complete, reliable, beautiful and comfortable country house with my own hands– this is the dream of almost every land owner.
Building a house yourself is an incredibly rewarding experience and a great opportunity to save money. cash, because All construction activities can be completed on your own without the involvement of third-party specialists. You just need to choose the right building material.
IN Lately Country houses made of foam blocks are becoming increasingly popular. This building material has good performance characteristics, is fireproof and relatively lightweight.
The blocks have big size, which allows you to build various kinds buildings with maximum speed. Working at an average pace, a house can be built in just a couple of months.
As for the monetary costs of construction, building a house from foam blocks will require much less material investment than furnishing brick construction, but slightly larger than the construction of a similar house made of wood.
Advantages
Flaws
- Low tolerance to high loads.
- Low rate of strength gain, accompanied by shrinkage.
- Risk of cracks.
It is best to use blocks made of high-quality autoclaved foam concrete. This material is less susceptible to shrinkage.
The load-bearing row of masonry must be reinforced with reinforcement.
Foundation for a house
The optimal foundation option for country house from the material in question is strip base. The foundation structure must be reinforced.
The dimensions of the tape are quite standard. The width of the tape should be 100-200 mm greater than the thickness of the walls of the house. The depth of the slab is up to 600 mm. Base – no more than 400 mm.
The foundation is built in a few simple steps.

First step
Mark the base in accordance with the layout of the future country house. For marking, use any suitable pegs and ordinary rope.
Second step
Dig a trench according to the markings. Install the formwork.
Third step
Fill the bottom of the trench with a 30 cm layer of sand and gravel mixture. The backfill must be compacted well. Fill in layers of 100 mm.
Fourth step
Cover the walls and bottom of the pit with moisture-proofing material.
Fifth step
Lay the reinforcing layer. Assemble a mesh from 10-12 mm rods with cells no larger than 15x15 cm. Tie the joints of the reinforcing bars with steel wire.
Sixth step
Pour the concrete. It is important that there are no air voids in the fill. To eliminate voids, use a vibrator or pierce the fill with a reinforcing rod.
Seventh step
Cover the frozen foundation with moisture-proofing material (roofing felt). Lay the strips with a minimum of 15 cm overlap.

Construction of walls
Start building walls. First make sure that the foundation structure is horizontal. It is important that the height difference does not exceed 30 mm. If there are more significant deviations, level them out using cement mortar.
It is important that the foam blocks are laid strictly horizontally along the longitudinal and transverse edges. Use a level to check horizontality. If distortions are detected, correct the position of the foam block with an ordinary rubber hammer.
Video - Laying foam blocks
The starting row of foam blocks must be laid out especially carefully. The accuracy of the construction of the entire country house directly depends on the correctness of its installation.
First step. Find the highest point concrete base. A level will help you at this stage.
Second step. Lay first building element
in the corner least distant from the highest point of the base.
Third step.
Install foam blocks in the remaining corners of the base. Fourth step. Stretch the rope between the corner foam blocks along the top edge of the wall.
Fifth step.
Fill the initial row with foam blocks in accordance with the stretched cord. If any kind of irregularities in the evenness of the masonry are detected, eliminate them using
sanding board
, and even better - with a plane. Remove dirt with a brush.
Reinforcement
After the first row is completely filled, reinforcing bars should be laid on top of the foam blocks. In the future, the reinforcement must be laid after installing every 4th row.
Place a smoothly curved steel rod in the corners.
First step. Using a grinder, prepare grooves measuring 40x40 mm at a distance of at least 60 mm from the edge of the building block.
Second step.
Clean the grooves from dust and moisten them with clean water.
Third step.
Fill the grooves with cement mortar to about half the volume.
Second step.
Place stainless steel anchors in the designated area. Place one end into the load-bearing wall, secure the other end into the seam of the partition. Such fasteners must be inserted into the load-bearing wall through one row of blocks.
Third step.
Secure the anchors with nails. It is also allowed to simply press the anchors into the solution without using nails.
Openings for windows and double-glazed windows Buy or make lintels yourself from hollow foam blocks for arranging the floor. The cross section of such jumpers should look like the letter P. Mark the cut areas on the foam block, then remove
inner part
using a hammer.
Install hollow foam blocks that look like the letter P on top of the opening being constructed. Install on wooden supports. For example, timber or boards will do.
Attach the supports with nails to the side walls of the opening. Place reinforcement in the inner strips and pour concrete. Do not remove supports until the poured concrete has gained strength.
Also, foam blocks can be laid on top of the opening being constructed on metal corners. Roof structure Arrange the roof of the house from
wooden beams
- and start building the roof.
- Choose the shape and type of roof at your discretion. The procedure for arranging the roof remains the same:
- rafters are installed;
- the sheathing is stuffed;
the necessary insulating materials are laid;
The final roof covering is installed. Choose roofing material according to your personal preferences and available budget. The surface layer of foam blocks is characterized by fairly intense moisture absorption. That's why
finished walls must be covered with external finishing. Otherwise, they will darken very quickly and begin to rapidly collapse. For exterior finishing walls can be used
various materials
. Choose according to your taste. The most commonly used solutions are: Choose the exterior finishing option that best suits you and get the job done.

Foam blocks are a modern and highly sought-after building material. This joint development of engineers and manufacturers is inexpensive, allows the construction of a structure in the shortest possible time, is safe from an environmental point of view, reliable and durable.
It is not surprising that more and more people are building residential buildings and dachas are made from this material. In this article we will look at popular projects of country houses made of foam block, and find out what nuances there are when using this material.
Description and features
Foam blocks are good because they have decent dimensions, allowing you to erect a building in a very short time. This makes the construction process quick and at the same time quite simple.
In general, in terms of speed of construction, no other building material can compare with houses made of foam blocks. In one summer you can build a country house, and in the fall you can celebrate your housewarming: with foam blocks this is a completely common situation.
A big advantage of the material is that immediately after building the frame of the house, you can begin installing communications and interior decoration.
The production of foam blocks is elementary, simple, but at the same time very interesting process. To prepare this building material, cement mortar is mixed with sand and water, supplementing all this with a special foaming agent. The last component gives finished material specific porous structure. But how the construction of a bathhouse from foam blocks occurs, and how this happens, you can understand by watching the video
In the video - how to build a country house from foam blocks:
The weight of one block is about 25 kg. It is necessary to take into account that this is a rather voluminous element. One block has the following standard parameters: 20x30x60 cm. Based on these figures, you can accurately calculate how many blocks will be needed to build a house of any size. Please keep in mind that the construction of one square meter The walls take approximately 8.3 blocks.
Foam blocks are fastened not with cement, like bricks, but with a special glue that reliably and firmly holds the wall elements in one plane.
Pros of foam blocks
Let's find out what advantages this unique building material has.
Foam blocks are inexpensive, which is very important nowadays. Of course, it is recommended to purchase this material with a reserve of approximately one-third due to its certain fragility, but even in this case, foam blocks are beneficial.
The blocks weigh a little, which makes the construction process easier. In addition, this advantage does not create a strong load on the foundation. Due to the fact that the foam blocks are of decent size, the process construction is underway at a fast pace.
The material is easy to process: it can be cut, sawed, hewn, giving it the required shape.
The video shows the advantages of foam blocks:
Foam blocks are environmentally friendly, safe for health, do not cause allergies, and maintain an excellent microclimate in the building. They contain only water, river sand and cement.
Thanks to their porous structure, the blocks provide excellent thermal insulation for a country house. Except this the most important characteristic foam blocks also protect interior spaces from external sounds.
The speed of construction of foam block houses is truly unique. So, a couple of working hands can cope with the construction of an average size country house from foam blocks in one summer.
Due to its lightness, the material does not require a solid foundation, which reduces the cost and speeds up the construction of the building. Building a house from foam blocks is like playing a real-time construction game.
It is very easy to decorate the outside of a country house made of foam concrete. After the walls are erected, workers receive a finished, flat surface that only needs to be painted. If there is a need and desire for a more thorough finishing, then you can easily decorate the outer walls of foam blocks with siding, lining, panels, or a block house.
The blocks have standard sizes and precise, regular geometric shapes, very convenient for construction.
Minuses
To complete the picture, it is also necessary to familiarize yourself with the shortcomings of the material.
Foam blocks are quite fragile - this is their main drawback. They easily crumble, break, break and become deformed when dropped. This is precisely the reason why when purchasing material it is recommended to immediately purchase a third more than the required quantity.
The material is highly susceptible to damage by water. Therefore, it is recommended to cover the outside of the house with protective material, as well as provide the building with high-quality waterproofing. Blocks are not the most durable building material. It is guaranteed to serve for 50 years, and then depending on your luck: it all depends on external conditions
, compliance with construction technology, careful operation, tightness of the protective cladding.
Due to the significant volume of blocks, the finished building turns out to be quite “clumsily” made and rough. This material cannot be used to make small, elegant parts. However, the problem is largely solved by the final external cladding of the house: it can be siding, lining, decorative rock, other interesting material.
House projects
House 6x8
A country house made of foam blocks with such parameters is a quite popular project. Such compact house will not take up much space on the site, and the saved usable space can be used for beds with vegetables and berries.
As a rule, house designs with an area of 6x8 are distinguished by their simplicity of design, the absence of “bells and whistles” and decorative excesses. Elements such as a terrace, attic, balconies, bay windows and others in in this case rarely used due to the need to save space.
But despite small sizes on an area of 48 m2 you can create a completely comfortable living space. And modern developers have come up with many projects for such small houses made of foam blocks, which provide all the necessary functional rooms. What will the extension look like? wooden house made of foam blocks, can be seen in the photo

This structure can be made in different architectural solutions, due to which the cost of construction can vary significantly. Therefore, choose a project based, among other things, on financial considerations. If you are building cottage, but if you plan to subsequently build on an attic or second floor, lay the required level of load in the foundation in advance.
This article will help you understand what they look like and how difficult it is to build such a structure.

Size 8x12
A house made of foam blocks with such parameters is modern and profitable solution housing issue. On a decent size area it can comfortably accommodate big family: there is enough space here for personal premises, and for common ones, and for utility rooms.
An 8x12 house made of foam blocks will cost much less than a brick one, and will even surpass it in thermal insulation properties.
In a house made of 8x12 foam blocks, you can completely equip comfortable life. The material allows you to maintain an excellent microclimate in the rooms, the walls breathe. The environmental friendliness of foam blocks is beyond doubt and has been scientifically proven by many tests. In this regard, blocks are superior to brick, to which various suspicious, untrustworthy additives are often added. But this article will help you understand how to do it correctly.
Size 8x12
Standard designs for 8x12 foam block houses are developed taking into account climatic zones and soil characteristics in these areas. Such a building contains all the necessary functional premises. Usually this:
- bedrooms (up to three separate rooms);
- large common living room;
- comfortable spacious kitchen;
- bathroom;
- utility room-storage room.
Without a doubt, various projects include different quantities rooms and differ different layouts. The choice is really large: it is possible to choose the ideal house project in each specific case.
You can quickly build a reliable, warm country house using foam blocks as a material. Block foam concrete has several varieties, differing overall dimensions, physical indicators.
The use of foam blocks is justified when constructing a building up to a 2-story size.
Quality indicators of foam blocks
The qualitative characteristics of the material have the following advantages:
- high thermal insulation performance;
- environmental friendliness;
- lightness, allowing the installation of lightweight types of foundations;
- ease of installation;
- increased sound insulation;
- moisture resistance.
The time spent on the construction of panel-block structures is significantly reduced. One-story houses They build literally in 3-4 weeks.
The cost-effectiveness of the material allows you to significantly reduce the budget costs required to build a full-fledged house.
Distinctive characteristics of foam concrete blocks are:
- high resistance to mold and fungal infections. Unlike wood, foam block is not subject to rotting;
- increased fire resistance also distinguishes foam blocks from wood.
The disadvantages of the materials are:
- the need for facade finishing;
- need for insulation;
- If installation technology or waterproofing is performed incorrectly, cracks appear and the material collapses.
D sip panel houses
Sip panels are high-tech elements ready for direct assembly. The construction period for a country house from such material is only 2-3 weeks.
The many advantages of the panels in question popularize the technology in modern low-rise construction. Walls erected by craftsmen from combined SIP panels have significant quality indicators:
- speed of assembly;
- no need for a monolithic, massive foundation;
- no shrinkage;
- possibility of construction in any season convenient for you.
Heat capacity
The increased heat capacity of SIP panels exceeds this indicator frame house by 50%. The absence of cold bridges guarantees long-lasting heat retention throughout the entire wall area.
Strength
A country house built using the material in question is more durable than frame structures.
House weight
A house with an area of up to 200 square meters weighs about 10-15 tons, which is up to 20 times less weight similar in quadrature and thermal conductivity to a brick structure.
Increased area
Due to the small thickness of the SIP panel, the area of the house being built increases. For example, standard wall thickness brickwork is 510mm. The thickness of the SIP material is 174mm.
It turns out that a house with dimensions of 10x10 made of brick will have an area of 80.64 m2, and of sip panels - 93.12 m2. Almost 13 squares - the difference is significant; they can accommodate any room, bathroom, utility room.
Country house made of sandwich panels
Sandwich panels are understandably popular in the construction of country houses. Multilayer material is easy to install; such a house does not require a massive foundation.
Photo 6 - Dacha. Sandwich panel house
Ease of house assembly is ensured by factory preparation structural elements: by cutting slabs into certain sizes, making grooves, fastening holes, helps builders assemble an object like a construction set.
A structure made of sandwich panels does not require facade finishing. Domestic Finishing work can be made using all kinds of materials without restrictions.
If you additionally insulate the walls with polystyrene, then the owner will significantly save on heating. A house built from the material in question requires 5 times less energy consumption than a structure made from traditional brick, reinforced concrete, or blocks.
