laying walls with foam blocks, price in estimate

Building a house from aerated concrete is considered one of the most economical options for private construction, based on the low cost of foam materials. But the construction of the box is only 30% of all work.

A huge part of the funds is allocated to the construction of the roof and finishing. It all depends on the complexity and intricacy of the project, the chosen type of foundation and roofing material, finishing work and progressiveness of building materials, number of floors, total area and other structural features.

An example of calculating an estimate for the construction of a house made of foam concrete blocks

The choice of foam blocks for building a house indicates reasonable savings for the developer. To assess the benefits of such a solution, you should first calculate the turnkey estimate. This will help plan future expenses and find out whether there is enough savings for construction in the family budget. In addition, a detailed listing of materials gives an objective picture of the upcoming construction and suggests ways to save money without damaging the house.

Sample estimate for the construction of a house made of 6×8 foam blocks on a turnkey basis

Estimates are drawn up based on the house design. As an example for independent calculation of materials, consider a small building made of foam blocks on a strip foundation, consisting of three rooms, a kitchen and a terrace.

Construction of the foundation

The foundation for a lightweight house made of foam blocks, built on dense soil, will not be too expensive. A one-story building can even be installed on poles, if the soil allows it, and for more difficult construction conditions, a monolithic reinforced concrete strip is suitable. We include it in the estimate as a sample.

We take the depth to be 60 cm plus 40 for the base part, and the width of the tape will depend on the masonry method and the chosen wall decoration. For a house made of foam blocks with brick lining, when built with half a stone, you need a strip foundation half a meter thick. According to the project, its total length will be 48.6 m.

Read about the features of choosing a foundation for a foam concrete house in this article.

Material consumption for construction:

• 195 m of d-10 reinforcement and 253 m of d-8 vertical jumpers, plus 220 m of tying wire.
• Concrete M300 (it is better to specify the brand when calculating the weight of the building) - 24.3 m3.
• Sand and gravel (2.5 m3 each) to form a cushion, wooden formwork.

All bulk goods must be ordered in reserve, as they are partially lost during unloading and during construction. Reinforcement is purchased taking into account the loss of footage at overlaps.

Roof

A simple and neat option for building a house is a gable roof. Its entire frame will be made of lumber of various sizes, which will not place excessive load on the foam block:

1. Mauerlat 28 m – timber 150x150.

2. Ridge 8 m – beam 120x150 mm.

3. Frame - taking into account the outlets, you will need a 4-meter beam of 50x150 mm with an installation step of approximately 1 m. That is, you will need to form at least 9 pairs of rafter legs (72 m or half a cube of timber).

4. The logs for the attic floor can be made from 100x150 mm timber, but you will have to look for 6-meter products. Their construction will require 0.7 m3.

5. 30x100 mm boards for roof sheathing and floor/ceiling installation on wooden floors are calculated based on the area of ​​each surface.

The arrangement of the insulating layer and the choice of roof covering is at the discretion of the owners. We insulated our sample with mineral wool and a wind-moisture-proof membrane over the entire area of ​​two slopes (64 m2); We will cover it with metal tiles.

Estimate for the foundation

Since foam concrete is a lightweight material, screw piles can be used when constructing a bathhouse, summer kitchen or small cottage. According to experts, for building a house of 1-2 floors, a strip foundation is more suitable. It can be monolithic or prefabricated, recessed or shallow. Such a foundation for a house looks quite labor-intensive and expensive, but it has a big advantage. A strip foundation makes it possible to lay a basement or cellar under a residential building made of foam block.

A monolithic base, which is difficult to manufacture and reliable in operation, is well suited for the sample. The estimate for construction work will contain all the costs of its installation.

1. For an area with non-heaving soil, we select a shallow foundation 0.6 m deep. The trench needs to be dug 20 cm deeper to make a sand cushion.

For blocks measuring 600×300×200 mm, we set the width of the base to 0.5 m. The foundation for the house will be poured from the outside into the formwork, so its final height is 0.6+0.4=1.0 m.

2. Determine the length of the tape:

The total length is 48.6 running meters.

4. In the construction estimate, we list the components necessary for mixing it yourself (if desired, you can order a ready-made, factory-made solution). Their quantity is determined based on the concrete grade M300. For 1 m 3 of mixture you will need:

To find out how much of each material is required, we multiply the standard filling parameters by the filling volume:

5. We calculate the amount of sand for filling under the foundation of a house made of foam blocks:

6. When building a monolithic foundation, reinforcement is always necessary. For our sample, we select a frame from two longitudinal rows, 2 rods each with a diameter of 12 mm. For transverse rows, reinforcement with a cross section of 10 mm will be required. With a jumper pitch of 0.5 m, the cross section of the frame is 30 × 0.65 m, the length of the rods is 0.35 m (horizontal) and 0.7 m (vertical). In total, for one structure (ring) you will need 0.35 × 2 + 0.7 × 2 = 2.1 m. In addition, for the joints on the jumpers you need to provide tires 3 × 4 = 12 pcs. 1 m each. Total 12 meters or 2 rods 6 m each.

7. We determine the total amount of reinforcement for the estimate for the construction of a house made of foam concrete: 48.6 × 4 + 12 = 206.4 m or 35 rods of 6 m each with a diameter of 12 mm.

8. Calculate the number of rings for jumpers: 48.6/0.5+1=98 sets or 35 rods of 6 m each.

9. To knit the reinforcement, use soft steel wire at the rate of 0.5 m for each connection. For jumpers you will need 98 × 4 = 392 pcs, for tires 12 × 4 = 48 pcs, a total of 440 ties × 0.5 m = 220 meters.

Estimate for foam concrete blocks for building a box

In the 6x8 house project, we plan to lay load-bearing walls in half a block. For internal partitions, a quarter of a stone is enough.

1. In a house made of foam blocks, choose a wall height of 2.8 m. It will require 14 elements in half a block. Taking into account the seam joints (14 pieces, 0.5 cm each), we get 2.87 m. In fact, the height of the walls inside the room will be 2.6-2.7 m (reduced due to the ceiling and screed).

(8+7.3+8+6+4+1.3)×2.8 m=96.88 m2 – area of ​​load-bearing walls.

For construction you will need: 96.88/0.06 (S spoon) = 1615 pieces of half-stone foam blocks.

3. In total, in the construction estimate we indicate the following number of foam concrete blocks: 1615+218=1833 pieces.

Important calculations: prices and required number of foam blocks, drawing up construction estimates

Block material has recently been increasingly used in the construction of residential buildings.
This is due to good performance characteristics, as well as low cost. To plan the construction of a house, it is necessary to prepare a project and calculate the consumption of foam concrete for the construction of walls.

Ready-made indicators will help you find out how much money you need to spend on purchasing materials.

What determines the cost of foam concrete blocks?

The price of foam concrete consists of several factors. Firstly, the initial cost is set by the manufacturer . Depending on what technology was used in production, whether new materials were used, modern equipment and improved molding techniques - all this directly affects the price indicator.

Since foam concrete is supplied for sale to warehouses in packages, its price also affects the final cost of the stone. For example, the packaging material used is stretch film, special tapes that are used to tie the blocks, as well as pallets on which the material is transported.

Several more factors that make up the price of blocks:

Foam concrete is divided into 3 groups according to density and strength. This indicator is designated by the letter D and indicates the density of the material. Structural blocks are the most expensive, their density is D1000-D1200 .

Structural and thermal insulation stones are considered average in price. Their density is D600-D900. The most affordable compared to previous options will be thermal insulation blocks with a density of D300-D500. They are inexpensive and are used to insulate monolithic walls from the outside.

The dimensions of foam concrete also affect the final price: the larger the block, the more expensive it will cost . When purchasing block material from a factory, the price will be 10-15% cheaper than when purchasing from intermediaries. It is better to find factories that independently produce foam concrete and offer it for sale.

Average prices for foam concrete by size

To build a box house, you need to understand how much you will have to spend on construction. To do this, check out the prices for the material. This table shows prices for 1 piece, 1 m 2 and 1 m 3, depending on the size of the foam block.

Attention! The table shows the price of foam blocks with a density of D600. If the density of the material is higher, its cost will also increase.

Laying cinder block walls

Cinder block wall

several decades earlier, it was built from a completely different material, because ferrous metallurgy waste in the form of blast furnace slag was used to produce this material. The predecessors of modern cinder blocks were aired in an open space for six to seven months in order to rid them of harmful substances as much as possible. Today, cinder block construction, which is considered one of the most popular and in demand among other building materials, appears to us in a completely different light.

Modern cinder block wall masonry

from which it is produced in a short time, is practically safe for human health, since its constituent elements are only pure materials. The masonry of cinder block walls, like the masonry of many other materials, is durable, economical, reliable, frost-resistant and affordable. For such irreplaceable qualities, cinder block has gained great popularity among lovers of private, country life, dacha lovers and gardeners.

Insulation of cinder block walls

It is best to carry out it from the outside, since insulating cinder block walls from the inside over time can lead to the accumulation of fungus due to high humidity between the wall and the coolant. All work related to the laying of cinder blocks and its subsequent finishing must be carried out by experienced craftsmen, because only by knowing modern technologies and the nuances of this construction can a high-quality result be achieved.

How to calculate how much is needed to lay the walls of a house?

To determine the number of foam blocks for building a house, you need to take into account several indicators :

All these parameters can be taken from the house design and the foam concrete dimensional grid.
The masonry scheme is determined before the construction of walls begins .
The height and length of the walls are indicated in the project, if it has been prepared. You also need to know the thickness of the walls: for example, for laying external walls they use a greater thickness than for laying interior partitions.

The number of window openings and doorways will help determine where the masonry will not go through, and will also make it clear where it is necessary to perform reinforcement, bandage the masonry and install lintels.

An example of calculating the required quantity

It is impossible to say exactly how many foam blocks will be needed to build a box at home.

When making calculations, you need to take block material with a reserve. During transportation, some blocks may become unusable due to destruction.

For example, you can take a two-story house with walls measuring 2.5 meters high and 12 meters long. The layout will be standard: 1 load-bearing wall per side and partitions. For the construction of external walls, a block of 600x400x200 mm will be used.

The calculations look like this:

This is exactly how many cubes of material will be needed to lay one floor, but door and window openings must be subtracted from this indicator.

To do this, calculate the perimeter of windows and doors, convert them to square meters and subtract the resulting number from 148 sq.m. (masonry area of ​​the first floor).

Master class on laying cinder block walls

Good day!
Many of us are involved in construction, and often, to save money, we do everything ourselves. The author of this article invites us to get acquainted with his master class, where he will tell you in detail how to properly lay cinder blocks, and perhaps this information will greatly help you in your construction affairs. In order to start building walls, you need to lay a foundation; in this case, a type of foundation was used, such as a strip foundation, which was leveled in advance using brickwork.

Let's start by removing any debris from the surface of the foundation using a regular broom.

In order to remove all unevenness that could appear on the foundation, we use a solution of thin consistency. The grade of cement we use is M400. Take a mixture of sand, mortar, water, and mix.

Use the resulting solution to smooth out all the unevenness.

Before we start building walls, we need to put waterproofing on the surface of the foundation. To do this, take roofing material and cut it to the required dimensions.

If you are doing this alone, then it is best to use one simple method; for this we need nylon thread and a brick.

We roll out the roofing material on a flat surface, and on top of it in the middle we place a nylon thread, which is tied to the brick.

Next, you need to bend the roofing felt in half, according to the dimensions we need.

Then we take the other end of the thread in our hands, so that the rope does not cut our hands, we tie a small wooden handle.

Next, you need to step on the folded roofing felt, take the end of the rope in your hands and pull it towards you. In this way you can cut the roofing material in half.

When we have cut the required number of strips of roofing felt, we begin to lay it on the foundation.

We fix the laid sheet of waterproofing with a cinder block, simply placing it on the surface, this is so that the wind does not blow it away.

You can start laying the walls; to do this, stretch the twine, thereby setting the level for the cinder block.

When all the corners are set and the diagonals are checked, let's start laying. Spread the solution evenly over the block. In order for there to be adhesion between the blocks, the solution must be placed on the end of the block itself, as shown in the photo.

Next, we place the block on the solution and press it against another block; if necessary, you can lightly tap on its surface with a mallet, this is in order to adjust the block in height and horizontally, so the block will settle to the level we need.

In order for the wall to come out smooth, the masonry must be laid using the so-called mooring cord, which we attach to a bent bracket, it is made from a rod from electrode No. 3.

We stretch the cord along the entire length of the wall, fix the brackets at the corners with bricks.

The cord should be as tight as possible, like a string.

The consistency of the mortar that we use for masonry should not be too liquid, and in order to save money, we place the mortar only on the area of ​​​​contact of the block with the surface we need.

After we place the block, the solution itself will fill all the voids.

We place the next block in its place; it may turn out that the block is higher than the stretched cord, this is due to the fact that the solution is not liquid.

In order to set the desired level, we use the same mallet, tap it, and the block will drop to the desired level, the excess solution will simply be squeezed out from under the block.

We remove excess solution using a trowel.

Using the same scheme, we place block by block until we reach the wall height we need. As a result of all these actions, we received a reliable design that will last for a very long time. Thank you all for your attention! Source Delivery of new homemade products to the post office

How to calculate construction costs?

To independently calculate the costs of foam blocks and workers’ compensation, you can use the prices given on average for Russia. For example, according to the calculations above, in order to lay out one floor, you will need about 60 cubic meters of foam block.

With the cost of a foam block in Moscow being about 3,000 rubles per 1 cubic meter, you will have to spend about 180,000 rubles for 60 cubic meters - this cost is approximate.

Masonry work per cubic meter is priced at an average of 1,800 rubles per cubic meter . The house on the ground floor has 60 cubic meters. From the formula you can understand that this is 108,000 rubles. Here you can add the cost of work on reinforcement, construction of openings and passages.

Estimate for building a house made of foam blocks

Before you start building a house, you need to assess your strength both physically and financially. An estimate for the construction of your house from a material such as foam blocks will help you do this.

Today, more and more people are striving to leave their city apartments and live outside of cramped and stuffy cities.

Some build cottages for permanent residence, others, due to various circumstances, want to acquire a country house for a summer vacation. In both cases, it is necessary to decide on materials and make a preliminary calculation of construction costs.

According to experienced, professional developers, foam blocks are the most profitable building material in all respects. Well, the estimate for building a house made of foam blocks will help in the correct distribution of money.

Based on real possibilities, everyone decides for himself whether to order turnkey construction of a house or build the structure himself. But, one way or another, it all starts with drawing up a clear plan of action and an estimate for the house.

House made of foam blocks: you need to calculate the estimate

Estimate for the construction of a house made of aerated concrete 10x10

A 10x10 meter house can be one-story, with an attic (f.1) or built on two floors (f.2). Such a building can easily accommodate a family of 4-6 people on its territory. Let's try not to miss any important points when creating an estimate for the construction of a house made of 10x10 aerated concrete. The construction of such a building must be divided into stages in which it is necessary to adhere to manufacturability and the period for the “duration” of the foundation.

1. Site preparation and foundation laying

To perform this type of work, you need to select the type of foundation. Due to the lightness of foam blocks, any type of base will do. The most acceptable is considered to be a strip or monolithic type of foundation with waterproofing of the base (forms 3,4). The budget for foundation construction consists of:

• conducting survey studies of terrain and soil;
• territory planning with axis breakdown;
• carrying out excavation work (mechanized or manual digging of a ditch, installation of a sand base with a tamper, a layer of crushed stone);
• installation of formwork;
• construction of a belt of intertwined reinforcement;
• pouring concrete.

Photo 1 - Strip type foundation

Photo 2 - Monolithic slab foundation Photo 3 - One-story house with an attic

Photo 4 - Two-story house made of aerated concrete

This takes into account the cost of renting formwork and the price of building materials:

• class A500 reinforcement with a diameter of 12-16 mm and d8mm reinforcement for tying or binding wire d6-8 mm;
• concrete;
• waterproofing;
• sand, crushed stone.

When determining the cost of materials, you need to take into account the cost of their delivery and, in some cases, unloading.

2. Construction of the frame

When drawing up an estimate for the construction of a house made of 10x10 aerated concrete, the cost of materials and work on their installation, delivery, and unloading are taken into account. To build a frame, calculate the cost:

• aerated concrete blocks;
• glue;
• work on laying cellular aerated concrete;
• materials for constructing a reinforced belt or installing columns;
• metal for window lintels.

Recently, a popular construction technology is the construction of a monolithic foundation connected together with corner columns or pylons. For a 10x10m house, the construction of 4 load-bearing columns will be sufficient. They are erected using special sets of column formwork. A 10x10 house with a wall height of 3 meters will occupy 10x4x3 = 120 sq.m of load-bearing wall area, excluding openings for windows and doors. Suitable for construction are gas blocks with a density of D500 and a thickness of 375 mm. For partition walls, use blocks with a smaller thickness. Knowing the size of the blocks offered by the best manufacturer, you can calculate the amount of material needed. The amount of glue is determined based on the manufacturer's recommendations.

Photo 8 - Sample estimate. Section 3. Walls and partitions

3. Installation of floors

To make the house strong and reliable, it is connected together by a frame. At the bottom, the structure is strengthened by a foundation, on the sides - by columns, and at the top - by a monolithic ceiling. This technology has proven itself and is today used in private, low-rise construction and in the construction of high-rise buildings and industrial facilities. When planning an estimate for the construction of a house made of 10x10 aerated concrete, you should determine the cost of the floor, which includes:

• formwork for floors;
• fittings and binding wire;
• concrete;
• insulation laid around the perimeter of the building.

An experienced team of builders will complete the monolithic vault quickly and efficiently.

4. Roof installation

The most important and costly step is installing the roof. In connection with the chosen option of hip, hip, multi-gable, dome roof, the cost of materials and components is taken into account. The main components in the estimate are the cost:

• covering material (metal tiles, slate, tiles);
• rafter system;
• components for drainage and other elements;
• structures for chimneys, ventilation;
• nails, screws.

5. Facing

Gas silicate blocks quickly absorb dampness, so experts recommend not tightening the outer cladding of the building (f.5). It can be done with insulation and facing tiles. You can simply cover the house with plaster and paint it. Therefore, the estimate for cladding includes the cost of:

• external facing material;
• interior plaster with wall and ceiling finishing;
• floor devices;
• windows, doors;
• stairs.

Planning the construction of a house made of foam blocks

Before you begin drawing up an estimate for building a house from foam blocks, purchasing building materials and, directly, building a house, you need to collect all the necessary documents. The main stage is the development of the project.

Its cost varies from 500 to 5000 dollars. First, a rough sketch is made - a sketch from which the designer can understand what the finished house should look like. Based on this sketch, the specialist creates a working drawing.

If you have certain knowledge and skills, you can draw up a house project yourself, then register it with the appropriate authority, after which you can begin drawing up an estimate and, in fact, the construction itself.

Important: if you are not given a building permit (passport for your own housing project), subsequently you will probably have difficulties connecting all the necessary communications to the house (electricity, water, gas, etc.).

When independently developing a project and drawing up an estimate for the construction of a house made of foam blocks, it is necessary to take into account the features of the landscape, the proximity of groundwater, soil type, climate zone, etc. nuances.

All this will help in the correct choice of building materials, both for laying the foundation, erecting the “box”, and for subsequent finishing work.

Approximate cost of a country house made of foam blocks

As a rule, a small private house costs 300-600 thousand rubles. This amount includes laying the foundation, erecting the “box,” installing the basement and roof. Additional costs will be for the installation of windows, doors, roofing and finishing.

Also, the final cost of building a house from foam blocks will depend on the number of rooms (the more isolated rooms inside the house, the more material will be spent on interior partitions and doors).

Another important factor is the region in which construction is planned. For example, in the middle zone the price tag for foam blocks ranges from 3 to 3.5 thousand rubles per cubic meter (28 pieces). At the same time, in the northern regions the cost of this building material will be slightly higher.

Estimating the cost of a foam block house foundation

How the constructed building will behave depends on the method of laying the foundation, its type and quality. The type of foundation is selected in accordance with the characteristics of the soil and the material from which the walls will be built.

Since foam blocks are lightweight building materials, a reinforced foundation is not required.

Accordingly, the cost of the house will be slightly lower than a building made of stone or brick. To build a house made of foam blocks, a simple strip foundation is quite suitable.

However, do not forget about the reinforcement ligament - even when constructing a light structure, it is necessary.

As for the region in which construction is planned, it is very important to take into account the degree of soil freezing in winter - this also determines what type of foundation should be.

The safest thing to do would be to consult on this issue with specialists who will be able to select the ideal base option for the future structure in accordance with the data specified in the project passport for a private residential house.

When applying for services from construction organizations, the cost of constructing a foundation, depending on its type, will be (approximately):

If you install a standard strip foundation yourself, construction costs will be approximately 2-3 thousand rubles per linear meter.

When the base is ready, you can begin building the basement. This stage is necessary because walls are not built directly on the foundation. The base will cost approximately 40,000 rubles.

Building your own home is cheaper than buying a ready-made one. True, for this you need to approach this process correctly. Using cinder blocks will significantly reduce costs. Next, we'll look at how much it costs to build a cinder block house and what you can save on.

Cinder block house

General information

Many people believe that building a house on their own is very time-consuming and expensive; it’s easier to buy a ready-made one. In reality this is not the case.

Of course, you will have to carry out all communications yourself, build a fence, and much more. But in the end you will get what you want. Sometimes it takes longer to find a suitable home than to build a new one.

First of all, you should understand that building a house is a step-by-step action plan and only strict adherence to it will allow you to save on construction. The first point of this plan is to calculate the cost.

Please note that if you do not have a plot, then its price should also be added to the cost of construction. It is difficult to give any figures here; it all depends on its area and location. In addition, costs in addition to construction should include the design of the house.

So, to find out how much it will cost to build a house, you need to find out how much you will have to spend on:

• Construction of the foundation.
• Construction of walls.
• Roofing installation.
• Construction works.

Calculation of construction costs

Foundation

The costs of constructing a strip foundation largely depend on its type, as well as on geological conditions. In most cases, a pile foundation is cheaper, but before you decide which type to choose and start making calculations, you need to obtain geological surveys.

Therefore, we will calculate the cost of a strip foundation. The first cost item will be site planning. First you need to remove the top fertile layer to level the area for marking. You can save on this operation if you do it yourself.

Calculation of the cost of a strip foundation is carried out as follows:

• The perimeter of the foundation is calculated.
• The volume of trenches is calculated.
• The required volume of concrete and the cost of its purchase are calculated.
• The required amount of reinforcement and boards and their price are calculated.
• All costs are summed up and the cost of construction work is added.

The perimeter of a house consists of the sum of its sides. For example, let's take a small house 6*4. Its perimeter will be (6+4)*2=20 m. Then the resulting figure should be multiplied by the depth, which in our case is 1.2 m and the width of the foundation is 0.5 m.

Thus, the volume of the trenches will be equal to - 20 * 0.5 * 1.2 = 12 m³. Please note that the width of the foundation is 0.4 m, the rest of the volume will be taken up by formwork.

Accordingly, to calculate the volume of concrete, you need to multiply the perimeter of the house by the depth and width, i.e. 20*1.2*0.4=9.6 m³ of concrete. Accordingly, this figure must be multiplied by the price of one cubic meter of concrete.

Since the foundation will require formwork, you need to calculate the side areas. The perimeter must be multiplied by the depth and the resulting value doubled. The result of the calculations can be used not only to calculate the forest, but also for the waterproofing area.

Once you know the price, you can easily calculate the cost of the material by multiplying it by the resulting figure. Don't forget to add shipping costs as well.

All that remains is to count the reinforcement. You will need vertical pins, which are installed in pairs every half meter. Accordingly, the calculation will be as follows - 20: 0.5 * 2 = 80 rods of 1.2 m each, i.e. 96 m, plus two “threads” - 20 * 2 = 40 m, which in total will be 136 m of reinforcement.

Walls

Next, you should find out how much cinder blocks cost for your future home. To do this, you need to count their number.

Cinder block dimensions

The sizes of foam block, gas block and cinder block are different. The standard size of cinder blocks is 390x190x188 mm , but there are other sizes - 400x200x200 mm . In addition, there are semi-blocks measuring 390x120x188 mm . They are also called partition blocks. In addition, they can vary in the degree of voidness: from solid to 40% voids .

Based on the size of the block, you can determine how many pieces will be needed to build a house, then find out how much 1 cinder block costs and calculate the total cost.

To do this you need:

• Calculate the area of ​​the box of the future building and calculate the area of ​​the openings. We multiply the length of each wall by the height, and then sum up the data of all the walls. From the obtained value, the area of ​​window and door openings should be calculated.
• Calculate the area of ​​the outer edge of the block.
• Divide the resulting value of the area of ​​the box of the future house by the area of ​​the block’s edge.
• Multiply the resulting value by the cost of one cinder block.
• Calculate the cost of masonry.
• All costs are added up.

For example, if the cinder blocks are of a standard size and placed with a wide edge outward, then the area of ​​one block will be 390 mm * 190 mm = 0.0741 m2. From this it follows that for one square meter of wall you will need: 1 / 0.0741 = 13.49, if you round it up, you get 14 blocks.

5% should be added to the resulting figure, since the possibility of combat during transportation must be taken into account. Then you need to find out how much one cinder block costs and multiply this figure by the number of blocks needed for one square meter of wall.

Wall masonry

This way you will find out how much a cinder block costs for one square meter of wall. We multiply the resulting figure by the number of square meters of the box of the future house and thus find out how much money will be spent on purchasing the material. However, procurement is not the same as building walls.

If the masonry will not be carried out independently, then you should find out how much it costs to lay a cinder block. Since one square meter of wall consists of 14 blocks , we multiply this value by the number of square meters of the box and by the price of laying one block.

The advantages of cinder blocks include the fact that their laying does not require high professionalism of a mason. Accordingly, the price for it will be lower, as well as for the blocks themselves.

Advice! You can save money by adding a plasticizer to cement. This will not only reduce cement consumption, but also increase its frost resistance.

Metal roofing

Roof

The cost of the roof is largely influenced by the shape of the roof, as well as the material that will be used. This determines what additional roofing elements that perform fastening and decorative functions will be needed.

The instructions for calculating the cost of a roof are similar to calculating walls. First of all, it is necessary to calculate the area of ​​the roofing. For example, if the roof is made of metal tiles, then you need to calculate the required number of sheets and multiply this value by the price of one sheet.

Roof installation

In addition, you should calculate the cost of purchasing wooden elements that will be needed for the construction of the frame and sheathing, as well as thermal and waterproofing. This also includes ventilation devices, a drainage system, roof windows, stairs and snow guards, as well as all kinds of decorative elements.

By adding up the cost of all the elements, you will find out the total amount that you will have to spend on roofing materials. As a rule, installation costs correspond to the cost of materials. If expensive elements are used, then the teams can make a concession and reduce the installation price.

Advice! The construction of the roof should be carried out in the same season as the construction of the walls to reduce the risk of snow or rain falling on the walls.

Conclusion

By approaching the calculation of the costs of building a house in stages, you can step by step calculate the cost of constructing various elements of the structure, then add up these indicators and get the total cost of building a house. This will avoid purchasing excess material and overspending.

Estimate for the construction of walls and roof frames

It is worth considering one more nuance. If you decide that the house will be one-story, with an ordinary non-residential attic, then at this stage everything is going correctly.

Well, if you want the building to have an attic, you should think about strengthening the foundation, since arranging an attic floor means increasing the load on the foundation.

In addition, to finish the attic, additional materials will be required that will provide the house with the necessary protection from the cold (thermal insulation).

You should also take into account the height of the ceilings in the house and the overall height of the building as a whole. The optimal ceiling height is 3 meters.

With these parameters, each floor of a house with an area of ​​10x10 m will require, on average, 28 cubic meters.

Thus, the cost of one floor of a building without finishing and without installing windows and doors will be about 100,000 rubles.

The type of roof, its shape and roofing materials are a purely individual question. Here everyone chooses what they like best: straight, broken, triangular or trapezoidal.

The material is also chosen at will: ondulin, metal tiles, etc. One way or another, according to average calculations, the construction of a roof frame is always equal to approximately 5% of the cost of building a box.

Cost of building a foam block house: estimate

Cost calculation for a foam block house box

As an example, let's take a house with an area of ​​100 m2, where each side is 10 m, and foam blocks with dimensions of 600x300x200 (mm).

We will carry out the calculation for 5 walls 3 m high - one main and four external, based on prices for 2016-2017.

Calculation of the number of blocks for external walls:

Important: the above calculations do not take into account window and door openings and external walls; they will need to be subtracted from the total area, the calculator will help with this

Number of blocks for the construction of a main wall:

To make it easier to calculate the cost of the total number of blocks, let’s convert the pieces into cubic meters: 27.7 pieces fit in 1 m3 (600x300x200).

We divide the total number of blocks by 27.7 and get 43.5 m3.

If we consider that the house will have at least 2-3 windows and at least 2 doors, then the resulting number of blocks comes with a margin.

Here you can do different things: either calculate the required number of blocks with an accuracy of 1 piece, or purchase materials with a reserve.

The second option is preferable. Thus, the approximate cost of the box is 130-500 thousand rubles.

Calculation of the number of cinder blocks per 1 m2 of wall

Cinder block is a building material for the construction of foundations, walls and partitions, buildings and industrial facilities.

It is made by pressing a slag concrete solution prepared from: cement, sand, volcanic ash, granite crushed stone, broken glass or brick, crushed stone, crushed concrete, fine expanded clay, river gravel, slag.

To calculate the required number of cinder block units per 1 m2, simple calculations are used.

Calculation of the amount of cinder block per square meter of wall

According to the requirements of GOST 6133, a standard cinder block is made with dimensions of 390x190x188 mm and has a volume of 0.014 sq. m. Based on the known size of the block, you can accurately calculate the volume of required building materials and the amount of cinder block. To calculate the approximate number of blocks in 1 sq. m, use simple mathematical techniques.

Option 1 - a wall as thick as half a block or 190 mm

Wall as thick as half a block

Knowing that the height of the cinder block is 188 mm and the length is 390 mm, its lateral area is calculated (after converting all values ​​to the SI system):

Slateral surface = 0.188 * 0.39 = 0.073 sq. m.

Now, knowing the area of ​​one block, you can calculate how many blocks will be needed to build 1 square meter. m. walls.

Nblocks in 1m2=1/0.073=13.64 pcs.

The resulting value is slightly larger than the actual value, since we did not take into account the thickness of the mortar joint.

If we take into account the seam thickness of 8–10 mm, then in reality we will need not 13.64 pieces, but exactly 13 pieces.

Option 2 - a wall one block or 390mm thick

A wall as thick as a block

The calculation algorithm is the same.

Slateral surface = 0.188 * 0.19 = 0.036 sq. m.

Nblocks in 1m2=1/0.036=27.99 pcs.

And taking into account the mortar joint, we will need 26 pieces of whole blocks.

This is the initial stage of calculations. To find out a more accurate quantity and consumption of building materials for the project, you need an estimate for construction work, that is, you need to calculate how many cinder blocks may be needed to build the entire house.

The total scope of work determines the total cost of the object, which consists of:

1. 30% - foundation, concrete mortar (adding cement, sand, water, slag aggregates), reinforcement frame, excavation work.
2. 45–50% - walls of the facility, including load-bearing structures and lintels.
3. 20–25% - roofing.

Let's assume that the entire volume of construction work will be based on the use of cinder blocks - the construction of a foundation, walls and partitions. To calculate the number of products pressing on the foundation, you need to know the weight of the load-bearing wall, which depends on the type of cinder blocks used. These can be either solid or slotted blocks. Their weight varies from 11 to 28 kg.

Calculation of the amount of cinder block per house

As a basis for calculations we take:

• Standard unit dimensions are 390x190x188 mm.
• The mass of the block with two voids is 17 kg.
• The dimensions of a one-story house are 8x8x3 m (Length x Width x Height).

Counting by rows of masonry - how many units of wall stone fit in one row. To do this, you need to know the dimensions of the block and the dimensions of the house. Then we will calculate how many cinder blocks per 1 sq. m. will be needed to build a supporting box.

1. To do this, we calculate the perimeter of the house: P house = 8 * 4 = 32 m.
2. To find out the number of units of products in one row, you need to divide the perimeter of the house by the length of the block: N pieces in 1 row = 32/0.39 = 82.05 pieces.
3. Next, we calculate the total number of rows. The height of the walls is divided by the height of the building block: N rows = 3/0.190 = 15.78 rows.
4. We find out the total number of blocks per house by multiplying: Ntotal=Npieces in 1 row*Nrows=82*16=1312 pieces.

Based on the results, you can calculate the weight of the building that will put pressure on the foundation: weight 1 pc. - 17 kg multiplied by the total number of units, we get 22304 kg. Since the preliminary calculation was carried out without taking into account window and door openings, they should be subtracted in the process of a more accurate calculation, just as their weight should be subtracted from the total weight of the load on the foundation.

To calculate the amount of mortar or glue for laying a cinder block, you should proceed from the thickness of the seam. For glue, the thickness of the seam is 2–3 mm, for mortar — 5–10 mm.

Since cinder blocks are usually stored on pallets, it is recommended to calculate the required number of pallets before purchasing them. One pallet holds 60 units of products. Therefore, based on the example above, a house measuring 8 x 8 x 3 m would require approximately 20 pallets.

For the foundation, the most optimal material will be blast furnace slag; for the walls, you can use any filler - ash slag, brick or stone rubble, crushed stone or gravel. To obtain a solid product, it will take 0.011 m3 of working solution to produce one unit of building stone. That is, from a bag of cement you will get 36 units of standard size with a bag weight of 50 kg.

The more accurately the equipment is configured, the less mortar will be consumed for laying blocks in rows, and the more products will be produced from one bag of cement.

Other materials: calculation

So, the calculation of the cost of the box is completed, now you can start calculating the costs of other elements.

Estimate for building materials

Even experienced builders will not be able to calculate how much money can be spent on, so we will proceed from approximate data, namely, we multiply the number of windows and doors by the average cost of materials.

If the work is carried out independently, this amount will be final. If you order services from construction organizations, you will need to add the cost of installation services.

Now you need to calculate the cost of floor coverings. If you want to end up with a durable building, then it is best to use monolithic concrete slabs for floors (in the case of building a two-story house).

If the building is one-story, you can use wood for the ceiling. Here it is worth paying attention to the need for wood processing, because its durability directly depends on the quality of the material.

Floor coverings for a one-story house will cost approximately 5-10 thousand rubles (depending on the region), while the construction of a two-story house can cost from 10 to 50 thousand rubles.

On average, to build a box at home you will need 100 bags of cement. The price of one bag ranges from 200 to 300 rubles. Total cost – 30,000 rubles. maximum.

Tip: it is better to use sifted sand for the solution. A ton of such material will cost 3,000 rubles.
