Reliable extension of a veranda to a house made of foam blocks

and receive painting as a gift. Until the end of the promotion:

EXTENSION TO A HOUSE MADE OF FOAM BLOCKS

Foam block is a reliable and durable building material that is extremely popular among developers. Foam blocks are light in weight and have the correct shape, so they are easy to build with and it is not difficult to erect a structure of any size and shape, including a two-story one.

They do not create a large load on the foundation, so for an extension it is not necessary to build a foundation that is costly and time-consuming. In addition, for the same reason, foam blocks are acceptable for use in loose and viscous soils. In terms of construction speed, foam block walls are comparable to frame walls.

An extension to a house made of foam blocks practically does not shrink and has no cracks that need to be additionally insulated. This is a solid, warm and durable structure, with a service life of at least 50 years. Like wood, this material “breathes”, which provides a pleasant microclimate in winter and summer.

Every owner dreams of a cozy veranda or terrace where they can relax after a hard day, sit and drink tea with the whole family. Most often, at the stage of building a house, they forget about it or there is simply not enough money for its construction.

To realize this dream, it is enough to make an extension. You can choose any material to build a veranda. This can be brick, timber, aerated concrete blocks and other materials. Adding a veranda to a house made of foam blocks would be the most suitable option. The veranda is a great place to relax and gather the whole family over a cup of tea in warm weather. Foam concrete blocks are a fairly new material.

They have a low cost. In addition, these blocks are light and easy to construct. To build an extension from foam blocks you do not need to have special skills. They are easy to saw, in addition, foam concrete does not absorb moisture, so it is perfect for external walls. Before you start adding a veranda, you need to collect some information about the main building: Scheme of adding a veranda to the house.

dimensions and type of foundation; condition of the walls; condition of the roof; soil properties. In addition, you need to think about the design of the extension itself. Will it look like a summer terrace, or will it be a covered veranda? As with any construction, you first need to decide on the size and layout of the future extension. You also need to answer the following questions: Is there a need to dismantle the existing roof or some of its elements? What will be the method of connecting the extension and the main building? How will the veranda be entered: a separate entrance or through rooms inside the main building? After answering all these questions and After collecting information about the house, you can begin construction.

Construction of a foundation for a veranda

Construction of the foundation for the veranda.

So, the veranda project has been chosen, you can start laying the foundation. You should examine the foundation of the house; for this you need to make a pit measuring about 1x1 m.

The depth of such a hole should be such that the base of the foundation of the old building is visible. It must be remembered that the foundation of the extension should be, if possible, the same type and depth as that of the main building. Otherwise, it is necessary to arrange an expansion joint.

Depending on the foundation of the old building, you can choose a columnar or strip type of foundation for the extension. The construction of a strip foundation is carried out by pouring concrete. The columnar foundation is made of brick. The latter will require less financial and labor costs.

After receiving information about the quality of the soil, you can begin digging a pit for the extension. Its depth should not be greater than the depth of the foundation of the main building. After installing the foundation, it should be covered with waterproofing.

Difficulties and errors

With a pre-created drawing and a well-thought-out plan for construction work, in principle, difficulties should not arise. But sometimes some people can make mistakes.

The most common of these are the following:

Incorrect use of blocks. This refers to the distribution of the material and its laying without technology, without maintaining the expansion joint and dressing rules.
Lack of use of reinforced posts, especially in floor areas. This can lead to complete deformation of the walls, even for single-story extensions.
Incorrect distribution of load on load-bearing walls. The blocks must be laid strictly according to technology, in accordance with the plan.
Not creating a reinforced concrete belt that will provide the walls with rigidity and strength.
Not strengthening the foundation makes it weak. Therefore, the foundation must be stable and strong. For light soils, strip and slab foundations are permitted.
Poor quality material. When purchasing, be sure to pay attention to the labeling and intended purpose of the foam blocks.
Ignoring styling techniques. The block should be laid only on the adhesive solution, with the exception of the first layer and the installation of side foam blocks to form corners.
Refusal to create sheathing and waterproofing, especially between the base and the walls, ventilation, use of vapor barriers for walls and thin waterproofing materials.
Carrying out construction in rainy weather. According to the rules, performing this action is strictly prohibited. It is better to choose dry weather, above + 5°C.
Calculations carried out with errors. It is necessary to calculate in detail the strength of the structure being built, taking into account future loads.

There is no need to make mistakes because you want to save money. You also need to comply with the standards of SP 339.1325800.2017.

When performing work, in order to avoid mistakes, you need to be very attentive to all the details and nuances of the work.

Construction of walls from foam concrete blocks

Scheme of constructing a veranda wall from foam concrete blocks.

First of all, you need to think about how to connect the wall of the main building with the newly erected wall. This can be done using metal brackets or fittings.

The construction of walls made of foam blocks (also brick and aerated concrete) must begin from the corners. For this, light solutions or special adhesive mixtures are used.

The surface of the block is smooth, which allows you to apply the solution in a thin layer. To improve adhesion, it is necessary to moisten the lower part of the foam block with water. The thickness of the seam of the first row of blocks should not be more than 3 cm.

Next, the verticality of the masonry is checked by level. Deviations can be leveled out with mortar by increasing or decreasing the thickness of the seam. Unevenness in masonry can always be removed with a grinding tool.

When building a veranda from foam blocks, it is necessary to follow the dressing rules. The second row of blocks needs to be shifted 10-15 cm relative to the first. This will make the structure more durable.

Finishing the extension

Light cement-based mineral plasters are ideal for finishing a veranda made of block materials. Their main difference from traditional mixtures is the type of sand used: instead of quartz, a light perlite filler is added to the composition.

Thanks to this, the finishing layer puts less load on the walls and has a high degree of vapor permeability and heat retention. Experts also recommend using this particular type of plaster, as it is quite resistant to cracks and other mechanical damage.

Important! During finishing, it is very important to maintain a constant temperature regime and not allow the finishing layer to dry out or freeze. Otherwise, cracks will quickly appear on the surface of the walls.

There is a certain order for finishing walls with a mineral mixture:

Clean the surface of the wall from dirt, level it using a mixture for laying blocks.
Use a float and brush to remove uneven surfaces after the reinforcing mortar has dried.
Apply the bottom layer of plaster using a float.
Lay out the plaster mesh, straighten it and press it into the uncured mortar.
Apply a second layer of plaster to the wall and smooth it with a trowel. Wait for the wall to dry.
Apply a final thin layer of finish and level it with a float, giving the surface the desired structure.
After the facade has completely dried, paint it with special paint for external work.

Extension to the house: additional points

Scheme of a veranda roof made of metal tiles.

Laying window and door lintels. For window and door lintels when building a veranda from foam concrete blocks, special U-shaped blocks are used.

They are lightweight, which makes it possible to avoid lifting equipment. In addition, such blocks make it possible to make openings longer than 1.75 m. For the lintel, it is necessary to install U-shaped foam blocks and formwork made of metal profiles and wooden beams.

Then reinforcement is installed into the groove of the block. The last step in installing the lintel will be filling the block with heavy concrete, which should be carefully compacted and leveled with the rest of the blocks. Installation of a reinforced belt. U-shaped foam blocks are also used to construct a reinforced belt.

Most often, the reinforcement is adopted with a diameter of 1 cm. Its ends are attached to the wall of the main building. The reinforced belt is designed to protect the walls from destruction and cracking.

Its installation occurs in the same way as the installation of lintels. Roof installation. The final stage of adding a veranda to the house is installing the roof. It can be made either single or double slope.

A pitched roof requires less financial investment, but this roof structure is cooler. In order to decide on the type of roof, it is best to contact specialists. In addition, it is better to insulate the finished roof, this will reduce heat loss.

Design and calculations for the construction of a veranda

At the stage of creating a project, first of all, you should decide on the dimensions of the room. The optimal width for such an extension is considered to be 3 meters. Large sizes will give the veranda a bulky look. The owner decides the length of the space himself - you can extend the room along the entire house or limit it to half or a third of the wall.

Next, select the type of foundation. The most successful way to build a veranda is to install it on poles. For this option, metal or asbestos pipes are laid. They are dug into the ground to the freezing depth and filled with a concrete mixture with a reinforcing rod. It is advisable to connect the protruding parts of the pipes around the perimeter with concrete tape. For a heavy terrace or with moving soil, it is advisable to lay a strip foundation.

For the walls of the terrace, a material similar to the walls of the house is most often used: foam blocks, bricks, beams. Each material has its own positive and negative qualities:

wood is environmentally friendly and budget-friendly, but needs special protection from decay;

concrete and brick are more difficult to work with and more expensive than wood;

metal is the most expensive, requires welding, gets very hot in the heat;

PVC deck boards are easy to process, do not require impregnation, and are cheap.

For a log building, a veranda made of polymer terrace boards is ideal. An extension to a brick house is made of brick if it does not overly burden the appearance of the structure in the complex. The construction of an open-type terrace requires moisture-resistant materials for interior decoration.

Roofs for extensions are usually pitched. Selecting material for this part of the veranda will not be a problem. Polycarbonate, transparent or colored, slate, tiles, galvanized would also look ideal. If the terrace roof extends the roof of the house, then it is more logical to use the same material. The width of the extension is small, so there is no need to make the slope large, otherwise the roof will lower the front part of the veranda too much.

Having determined the dimensions and selected the material, they draw up a drawing or sketch of the future extension. The finished veranda construction project must be approved by a government agency, whose employees, after studying the documents, will make corrections and issue a permit. It is better to do this during the winter season, as the procedure can last about 3 months. This step can only be skipped if the extension is planned without a foundation.

Next, you need to determine the location of the building, limit it with pegs and tapes to clarify the dimensions. The location is selected taking into account several factors:

location of the entrance door to the living space;
location of the building relative to the cardinal directions;
view from the future terrace;
the nature of the soil, which determines the type of foundation;
terrain features so that the general style of the site and the house is not disturbed.

To ensure that the building does not fall out of the general style, the design is developed in accordance with the appearance of the house. At the end of the preparatory stage, the budget for the construction of the veranda is calculated, the necessary materials, consumables, and tools are purchased.

Features of adding a veranda made of foam blocks to a wooden house

Based on materials from the site: https://ostroymaterialah.ru

The veranda in the house performs several important functions at once. Firstly, it protects the front door and hallway from rain and snow. Secondly, this light extension gives the building a harmonious and complete appearance.

And thirdly, the veranda is a very convenient place for summer outdoor recreation. A structure of this type must, of course, be built in compliance with certain technologies. Further in the article we will look into all the details of how to attach a veranda to the house correctly.

Choosing veranda sizes

The size of the veranda depends on the size of the house and is selected based on the maximum harmonious combination with the main building. However, some users approach the problem from an operational point of view. They consider functionality first, and appearance is considered last. This approach seems more rational, although architectural criteria should not be discounted.

As a rule, the veranda occupies the facade (entirely or only part). Less often, it is made into a corner, occupying a section of the facade and the end side of the house. The choice depends on the preferences of the owner and the configuration of the site - sometimes the distance from the walls of the house to the fence does not allow the construction of a full-fledged extension. Sometimes other buildings or landscaping elements get in the way. Therefore, when choosing a size, you should take all factors into account. It is recommended to draw up a site plan (to scale) and mark the proposed veranda on it. This will allow you to visualize the location and area of the extension, and ensure that the distances to the fence (at least 1 m) or other objects are maintained.

Work plan

Before you start building a veranda, you should definitely draw up a project.

It must include drawings of the structure from the two facades, as well as its plan from above. Of course, you must first make all the necessary calculations. This work is carried out guided by the following recommendations:

The foundation of the veranda should lie at the same depth as that of the house itself. If this condition is not met, in the spring the extension will simply move away from the wall. The roof of the veranda should be flatter than that of the main building. The walls of the veranda, like its foundation, are not rigidly connected to similar structures of the house.

These two structures have different weights, and therefore they will shrink differently. The gaps between the walls of the house and the veranda are closed in different ways, depending on the material used in construction. The dimensions of the veranda should not exceed 1/3 of the area of the house itself. Otherwise, this light extension will look ugly in the overall exterior of the building. It is best to choose the same material for the veranda that the building itself is made of.

This rule is especially true for houses assembled from timber or logs. A foam block or brick extension next to such structures will not look very nice. In this case, it is better to build a panel or log veranda.

The correct answer to the question of how to attach a veranda to a house (photos of beautiful and durable structures of this type can be seen on the page) - durable and comfortable - also lies in the selection of high-quality materials for it. Despite the fact that the structure is small and not as important as the residential building itself, it should be erected thoroughly, adhering to all recommendations.

Where to begin

Many owners of private houses ask the same question: “I want to make an extension to the house, where to start?”

You need to start by figuring out what size the building will be. We also need to decide what material we will build from.

If the main house is wooden, it is also better to build the extension from wood. If the main structure is stone, it would be more logical to choose brick or concrete blocks for the extension.

But there will be nothing terrible if you make an extension to a stone building from wood, and to a wooden one from brick. It will look normal and correct. There are many examples of such buildings.

Record the dimensions of the future extension on paper: make a drawing. It's not as difficult as it seems. It is necessary to draw a plan, that is, a top view of the structure and several sections - what the structures will look like if they are cut vertically. It will be useful to make drawings of individual joints of structural parts. Enter the dimensions.

A basic drawing is necessary for any construction. Having completed it on paper, you will already see what you will get as a result of construction.

Often masters of their craft say that they imagine everything in their heads and do not need drawings. This may be true, but there is a risk that you will still miss something, and then you will need to redo some of the work.

Possible options for the location of the extension relative to the main building.

We choose the location for the construction of the extension on the side where there are no windows. Usually the door to the house is inside the extension. That is, when leaving the house, we find ourselves in the outbuilding, and from the outbuilding we enter the plot. In this case, the extension serves as a veranda or entryway. This option is the simplest and most economical, but other schemes are also possible.

Pouring the foundation

When answering the question of how to attach a veranda to a house, first of all you should decide on the type of foundation for it. The foundation for such a light extension is usually made of columnar or strip. The choice of a specific variety depends on what materials are used to build the extension.

For panel and cobblestone construction, an inexpensive columnar one is also perfect. A strip structure should be erected under brick and foam block verandas. The order of work in this case will be as follows:

A trench is dug under the foundation, the depth of which should be slightly lower than the concrete base of the house foundation strip. A layer of sand is poured onto its bottom (to the level of the base) with compaction. Formwork from boards is installed on the sides of the trench. Wooden blocks 5 cm thick are laid on its bottom. A reinforcement frame is installed on them, knitted from a 12 mm rod. Then everything is filled with a concrete mixture (cement x sand x crushed stone in a ratio of 1: 3: 4).

The question of how to properly attach a veranda to a house also comes down to constructing a reliable foundation. Therefore, it is impossible to deviate from the technology described above.

The concrete mixture for the foundation of the veranda should be of high quality, and the reinforcement should be knitted from a fairly thick rod. The formwork is removed a day or two after pouring. After another 25-26 days, you can begin waterproofing the tape and building walls.

Video description

A veranda is considered a closed building, which is a continuation of the house with a common roof. The structure can be with solid walls or partial glazing. A veranda is usually added to a finished house to increase its usable area.

Extension to a cobblestone house

Well, the foundation is poured. What's next?

And then you can start building the walls. The technology of this process depends on the material chosen for assembly. First, let's figure out how to attach a veranda to a house made of timber.

This option will be an excellent solution for a wooden building. Cobblestone and log houses with such verandas look very beautiful. However, wood is a capricious material, and when using it, it is imperative to adhere to the prescribed technology.

First of all, you will need to choose the right timber itself. It is better if it is “winter”. This material cracks much less and shrinks less.

After the foundation is waterproofed with two layers of roofing material on bitumen mastic, you can begin laying the first crown.

It is attached to the base of the house using anchor bolts cast into the foundation. Next, the joists are installed under the floor. Then the walls are assembled, connecting the beams at the corners using the “half-tree” method.

If the veranda to the timber house is intended to be closed, the laying of the material continues up to the roof. If it is open - to the required height. In the latter case, at the next stage, racks are installed in the corners, which are best mounted on galvanized metal corners.

We create the perfect project

The location of the veranda is key: the extension should create a unified style with the house. This location will provide a shady area: you can relax without being exposed to excessive sunlight. Wind load is an important factor: the design must be reliable and safe, providing maximum comfort of use in any weather.

At your discretion, the entrance can be from the street, from the building part or through a through purpose. This option is predetermined by the operating format and the customer’s plans. In this case, it is necessary to provide for the situation with drafts, which are undesirable for any type of use of the living space.

Brick structures

Next, let's look at how to attach a veranda to a house made of brick or concrete. Of course, a light wooden veranda will fit well into the exterior of such a building.

However, a solid house will look much more solid with a brick extension of this type. It is not too difficult to build such a veranda yourself. The masonry mortar is prepared as follows: mix three shovels of sand and one of cement in some container and fill it all with water in such an amount to form a plastic mortar.

The laying of pillars is carried out with bandaging of seams, using plumb lines and orders. The thickness of the joints between bricks should be about 0.8-1 cm.

Long metal rods should be poured into the foundation at the location of the pillars (under the roof). The masonry is carried out around them using the one and a half brick method. The space in the center is filled with concrete.

The question of how to attach a veranda to a brick house also comes down to the construction of a reliable parapet.

Its assembly begins after the supporting pillars are ready. When assembling the parapet, a good solution would be to use some original masonry method. For example, with the installation of bricks at an angle of 45 degrees. The parapet can also be made of wood or a spectacular forged one can be installed.

Consumables and tools

What supplies and tools will be needed to build the extension:

Container, shovel, mixer for mixing solutions (cement-sand, as well as glue).
Tools for marking (construction cord, rulers (square), tape measure, levels, pencil).
Hacksaw for cutting blocks.
Trowel for tile work (with teeth).
Rubber hammer, foam concrete plane, brushes for moistening the concrete surface, trowel.
Cement, sand, gravel (up to 15 mm), running water, plasticizers for preparing cement mortar, pouring the foundation and backfilling the sinuses.
Wall chaser for making grooves.
Dry construction adhesive.
Reinforcement in the form of steel rods or reinforced mesh.
Materials for formwork for lintels and the formation of a concrete ring.

When performing masonry work, it is important to correctly fill joints and apply mixtures. It is especially worth paying close attention to the laying of the first tier of blocks.

The amount of materials and necessary tools is determined at the preparation stage.

Foam block buildings

This is also a good material for constructing a veranda.

Lightness, like wood, and durability, like brick, are its main advantages. Most often, closed structures are built from foam blocks. The only difference between such a veranda and an ordinary extension is its very large windows.

However, purely technologically, masonry from this material is somewhat more complicated than from brick. So, let's see how to attach a veranda to a house made of foam blocks. In this case, laying begins from the corners.

When using foam blocks, moorings must be installed. If even the slightest distortion is allowed during the masonry process, cracks may subsequently appear along the fragile walls due to the stresses arising in them. Each subsequent row is shifted by 10-15 cm relative to the previous one.

When laying, not a cement mixture is used, but a special adhesive solution. Only the first row of blocks is laid on cement. After the walls are built almost to the very top, an insulated armored belt should be installed on them.

Glazing

Glazing of the veranda is done in different ways: using metal-plastic, polycarbonate, PVC film, aluminum profile, wood. These days, the most popular are plastic windows.

The advantages of this choice include:

guaranteed long service life;
frost resistance;
dustproof;
the double-glazed window has good sound insulation;
do not deform under the influence of sunlight;
waterproof - unlike wood, they do not absorb moisture;
do not require painting, antibacterial or anti-corrosion impregnation;
ease of care;
easy to install.

Among the disadvantages, it should be noted that plastic is not a natural material; some types of it can release toxic substances. When purchasing a double-glazed window, you should ask the selling party for a certificate for the product, which indicates the hazard class. If the plastic is not of very high quality, over time it may lose its shine and become dull.

Pure plastic is weak and may not withstand the weight of glass, so metal-plastic bags are more often used for glazing. This structure is heavy and requires a load-bearing support. Non-reinforced plastic is used on lightweight structures; it has thin, non-tempered glass. Such windows are fragile and dangerous.

To install metal-plastic windows, wooden beams (100 by 150 mm) are suitable as supports. During the installation of double-glazed windows, special fasteners are used to connect the structure to the end of the frame. The resulting cracks are sealed with polyurethane foam.

The same rules apply when glazing the veranda ceiling, if necessary. The ceiling frame must be strong to hold metal-plastic bags, so it is easier to use polycarbonate. Sometimes they provide ceiling windows, which looks original. For ventilation using ceiling structures, a remote control is usually provided.

Plastic windows retain heat well and are suitable for winter verandas equipped with a fireplace or other heating means. Due to the nature of their manufacturing, metal-plastic structures cannot be too large. If you need floor-to-ceiling windows, you should select other materials (wood, aluminum).

Glazing of the veranda can be partial or panoramic. In the first case, windows are not installed on all walls. This is a cheaper option, but the extension will not be light enough. If the windows from the rooms face the veranda, the rooms will remain poorly lit. Panoramic glazing touches all external walls, sometimes even the ceiling. This extension receives the maximum amount of natural light.

Opening methods

Depending on the method of opening the frames, you can choose any suitable glazing.

The swing option is the most popular. The package consists of two or three parts, and only one or two parts can swing open, while the central one remains motionless. The ability to open a window increases the cost of the design, so not every section is ordered movable.
Sliding frames move on special skids in one or different directions. Each section overlaps the other when offset. This design is good for small verandas, as it does not take up much space.

Joining walls

Thus, we have figured out how to attach a veranda to a house using materials such as brick, foam blocks and timber.

However, the owners of suburban areas who decide to build such a structure will definitely have a question about how to properly join the walls. As already mentioned, the house and the veranda are not immediately firmly connected due to shrinkage. It is best to simply foam the gaps between the foam block or brick wall and the house.

You can also use special movable fasteners with grooves. If the veranda was built from wood, the gaps are usually covered with vertical beams. In most cases, a tarred board is laid between the foundations of the veranda and the house.

Deciding on the shape and design set

The idea of creating a built-in veranda is implemented at the design stage. The attached one is mounted on its own foundation. These options differ in installation specifics and cost, but, as experts note, this is due to the desire for increased living comfort.

Rectangular shapes are recognized as classic; their use is widespread due to their versatility. Round and semicircular shapes are usually used when creating classic exterior design. Polygonal shapes serve as a special structural element in complex designs.

A little bit about yourself

But first, let me introduce myself. My name is Pavel Usmanov, and I have first-hand knowledge of building houses. In 2006, I graduated from Arkhangelsk State Technical University with a degree in Industrial and Civil Construction.

Having received a diploma in construction, I began my journey of experimentation in search of the ideal field of activity. I was involved in the restoration of cultural heritage monuments, worked as a design engineer, and was engaged in panel housing construction. The practice was very varied.

However, I chose the construction of houses from aerated concrete blocks. “Plastic” building material allows you to implement the most daring architectural solutions. This freedom of construction thought fascinated and fascinated me.

Together with a team of experienced specialists, we created a company that is engaged in the construction of houses from aerated concrete frame blocks and other materials. Our catalog contains photographs of already erected buildings, as well as projects created by me even before the appearance of DST.

One-story houses made of aerated concrete with a terrace and veranda

To avoid confusion, I suggest you immediately understand what a terrace and a veranda are. Despite the abundance of conflicting information on the Internet, you should know that these concepts are not synonymous.

Photo 1. House with a veranda and terrace
What is a veranda

A spacious, completely enclosed, usually unheated terrace in the cold season.
In most cases, the veranda floor is installed at the same height as the floor in the entire house.
The lower part of the veranda walls is made of brick, aerated concrete, stone or wood. The top of the structure is panoramic glazing.
Usually a permanent roof is built for the veranda, which is part of the roof of the house.

Roof

The question of how to attach a veranda to a house also comes down to how to properly assemble its roof.

This structure is usually covered with a pitched roof. The racks are attached to the crowns of the cobblestone walls on one side. Next, the rafters are laid.

If the walls are brick, they can be fixed to ordinary corners, having first assembled the Mauerlat. If the building is made of cobblestones, it is better to use special “sled” fasteners. The fact is that cobblestone verandas shrink very strongly due to the drying of the wood.

The next step in assembling the roof should be waterproofing. To protect the tree from moisture, a plastic film is mounted on the rafters with a slight sag. Then the sheathing is filled and the roof itself is assembled.

Floors

At the final stage of construction, the floors are installed in the veranda (they can be assembled before laying the walls). If the structure is completely open, a decking board should be used to assemble them. This material is not at all afraid of moisture.

If this option seems too expensive to the home owners, you can take a regular edged board. However, in this case, when assembling the floor, it is worth leaving small gaps (2 mm) between the boards. Water that gets inside the veranda will go into them.

Well, we hope we have answered the question in sufficient detail about how to attach a veranda to a house with your own hands.

This matter is actually not particularly difficult. The most important thing is to adhere to the required technologies, and then you will get a beautiful, high-quality, reliable and durable summer extension to your house. Reliable extension of a veranda to a house made of foam blocks. Construction of a foundation for a veranda. Construction of walls from foam concrete blocks. Extension to a house: additional points. Features of adding a veranda from foam blocks to a wooden house. built, the garden plot is in order, but still something is missing. Every owner dreams of a cozy veranda or terrace where they can relax after a hard day, sit and drink tea with the whole family. Most often, at the stage of building a house, they forget about it or there is simply not enough money for its construction.

Why should you choose foam concrete for construction? This is a material made from natural ingredients: cement, sand and water; in addition, the mixture acquires special properties thanks to special foam. Due to its porous structure, the foam concrete block has some very important advantages:

Good thermal insulation and noise insulation qualities. Foam concrete will create a quiet and cozy room that will be comfortable both in winter and in summer.
Correct geometric dimensions. The foam block is larger in size than a brick, in addition, it has a completely flat surface. This speeds up and simplifies masonry, and even people far from the construction industry can handle it.
Strength combined with relatively low weight. Foam blocks have been used in low-rise construction for a long time, they have proven their effectiveness. With their help, you can build a reliable structure that will last for many years.

Design of a veranda made of foam blocks and construction of a foundation

A veranda made of foam blocks with your own hands is most often built on a strip foundation, which must be correctly attached to an existing foundation. The choice of connection depends on whether the extension was originally planned and when the main building was built. If the construction of a veranda was included in the project, both the house and the extension are built on a common monolithic foundation, which is a single concrete strip along the perimeter of the structures. It is possible to build a veranda on a strip foundation made of foam blocks, for example brand D1200.

If the house was first built, and then the question of creating a veranda arose, two options for attaching the foundations are possible:

If the house was built a long time ago, and the main shrinkage processes have been completed, then a rigid fastening can be used. It is created using metal pins that are inserted into drilled holes in an existing base.

They are then tied to the new reinforcement cage and it is poured with concrete. As a result, the new foundation will become a full part of the overall foundation of the house.

If the house itself was recently completed, a rigid grip is unacceptable. The processes of settlement of the building and veranda will continue, and they may proceed unevenly, which will lead to the appearance of cracks. In this case, an expansion joint is laid between them: for this purpose, a wooden shield can be used, which is laid between the foundations and filled with concrete.

The foundation is built in the same way as a regular strip foundation. A trench is dug along the perimeter of the building, into which special reinforcement with a diameter of at least 10 mm is installed, formwork is installed, and the trench is filled with concrete.

Step-by-step instruction

To make it easier to understand the nuances of individual stages of construction, see the instructions with photos for performing the main types of work. In addition, in addition to step-by-step recommendations, a video is attached with an overview of the technological nuances associated with arranging the foundation and erecting the walls of an extension to a house made of foam blocks.

Project development and territory marking

First of all, draw up a diagram of the location of all load-bearing walls and partitions, taking into account the necessary layout of the future extension. Make design drawings to scale in relation to the actual dimensions of the structure and the existing building.

After clearing the area and removing the fertile soil layer, transfer the center lines of the future foundation to the area. The correct geometry of the extension to the house depends on the accuracy of the work at this stage.

You can check the accuracy of angles using the well-known Pythagorean theorem, and you won’t have to remember your school math course and calculate anything; there is a simpler way. Place points on two walls at a distance of 3 and 4 m from the corner; the measurement between them should show 5 m. In this case, you can be sure that the angle is exactly 90 degrees.

Pouring the foundation

Using the completed markings, we dig a trench under the foundation. Its width should be 5-10 cm greater than the thickness of the wall. In some cases, when exterior finishing is planned using heavy materials (stone, tile, brick), the width is increased taking into account the insulation so as to provide support for the cladding.

We make the formwork from boards; you can use used lumber and plywood left over from the main construction. For the convenience of pouring concrete with mortar and speeding up work on arranging the foundation, we align the top line with a level.

Construction of walls from foam concrete blocks

Scheme of constructing a veranda wall from foam concrete blocks.

First of all, you need to think about how to connect the wall of the main building with the newly erected wall. This can be done using metal brackets or fittings.

The construction of walls made of foam blocks (also brick and aerated concrete) must begin from the corners. For this, light solutions or special adhesive mixtures are used.

How to build correctly: do-it-yourself installation technology

The step-by-step instructions for constructing an extension first consist of performing the preparatory work:

Assess the condition of the house to which the structure will be installed.
Determine the areas where communications and utility networks will pass.
Make a project and have it approved by the architect's office, receiving an certifying document and making notes on the house plan.
Mark the foundation that will be connected to the foundation of the main building in accordance with the drawing.
Purchase the required amount of consumables and prepare tools.
Prepare the soil, foundation pit, in accordance with regulatory construction rules, pour the foundation onto pre-installed metal reinforcement and backfill the sinuses. If the project includes iron piles, install them.

After the preparatory work and the completed foundation, the construction installation of foam blocks begins.

Necessary:

Mark the installation of foam material.
Prepare a sand-cement mortar, pour it under the markings, placing the first layer of blocks on it.
Pay special attention to laying the corners, securely fixing them according to the plan, maintaining the level and tension of the cord along which the laying will be done.
Prepare the adhesive solution according to the manufacturer's instructions.
Perform installation by shifting each subsequent row by half the length of the block. Apply the glue with a notched trowel, spreading it evenly over the bottom surface.
Carefully cut off the excess parts of the foam block with a hacksaw.
After laying the lintels over the windows and doors, by pouring concrete into the installed formwork, the openings are blocked to continue further installation of the blocks.
After the masonry is completed, an armored belt is formed along the plane of the walls at the end and the overlapping structure is assembled.
After the work is completed, you can go over the cracks with sealant.
To improve thermal insulation, a second layer of foam blocks is laid.
In areas with high humidity, they are laid with waterproofing material.
After the completed construction, you can already carry out finishing work.

Many craftsmen recommend using reinforcement with steel rods during the installation process. This will make the structure even stronger and more stable.

Features of construction for a wooden building

When building an extension to a wooden building:

Determined by the method of docking and the level of pairing.
The bases are rigidly fixed with reinforcing rods.
An expansion seam is formed.
perform foundation work.
After installing the base, the blocks are laid according to the technology indicated above, so the laying rules are the same for all types of houses.

Correctly applied adhesive composition reliably connects the blocks and reduces the thickness of the seams.

Why foam block

Foam concrete as a building material

Foam concrete blocks are almost ideal building materials, this is especially true for those cases when a house is built independently, with your own hands. Foam concrete blocks are lightweight and easy to process; for example, they can be easily sawed with a regular hacksaw. Also, their installation does not require special skills, unlike laying bricks.

Foam concrete material is quite easily delivered to those settlements that are considered inaccessible. Comparing foam concrete and other similar building materials, we can highlight higher strength qualities, as well as relatively low cost .

When comparing foam concrete and gas silicate blocks, attention is drawn to the fact that their environmental, fire-resistant, heat and sound insulation parameters are almost at the same level.

But gas silicate blocks have a very porous structure, and therefore higher water absorption. Also, compared to foam concrete blocks, the frost resistance of gas silicate is low, so it is most often used for internal partitions.

The properties of foam concrete and its brand are determined by the density of foam concrete. The best heat and sound insulation qualities are for the material whose density is lower, but with increasing density, its strength increases.

When choosing a brand of foam concrete, it is worth deciding what the purpose of the material is. For load-bearing walls, in the case of building a two-story house, it is worth choosing stronger ones, which are structural or thermal structural. Well, in the case when the question of how much it costs to build a bathhouse from foam blocks is being decided, then you can settle on heat-insulating blocks.
