How to calculate the number of bricks per house - construction and cladding. Brickwork calculator and calculation of the amount of materials Basement brickwork calculator online

Despite the rich assortment of building materials intended for the construction of one's own housing, brick does not lose its leading position to competitors. The demand for bricks when laying a house is due to many factors, ranging from the possibility of a wide choice of its types to a variety of laying methods.

Types and sizes of bricks

The start of construction is preceded by the calculation and purchase of the required building materials. Correctly carried out calculation will prevent the shortage of material during construction or its surplus in large quantities. Experts recommend purchasing bricks one time to avoid discrepancies in color. To carry out calculations by the amount of material, the following information will be required:

type of bricks used;
masonry method, determined based on the optimal thickness of the walls of the future housing;
the area of internal partitions and external walls of housing is calculated separately;
dimensions of future windows and doors are taken into account.

Depending on the purpose of the building, in what climatic conditions it will be located, choose the type of brick. According to the material of manufacture, it is classified into the following types:

Adobe products consist of clay and all kinds of fillers.
The most common ceramic material is fired clay.
Sand-lime brick includes sand and lime.
The hyperpressed material includes lime and cement.
Clinker bricks are produced on the basis of special baked clay.
Refractory clay is the source of making fireclay bricks.

Depending on the purpose of use, a brick can be:

Construction (ordinary). Suitable for interior and exterior walls of buildings. Given its unattractive appearance, the likelihood of minor chips, when used outdoors, the walls of future housing are insulated and protected. The external condition of the product does not reduce its strength.
Facing (facade, front) material is characterized by an ideal surface and the absence of defects. Ceramic, silicate and hyperpressed products can act as a facing material. The maximum deviations in dimensions according to GOST are 2, 3 and 4 cm in height, width and length, respectively.

In places of high humidity (lowlands or natural areas with a cold climate), ceramic material is best suited due to its slight hygroscopicity. In this case, it is better to refuse the option of silicate brick because of its hydrophobic properties. The most suitable operating conditions for silicate material are dry and hot latitudes. Facing brick, in turn, is divided into textured and facade material.

Depending on the filling, the brick is divided into solid and hollow.

Important ! For the load-bearing walls of multi-storey buildings, only full-bodied material is used. Hollow products are great for interior partitions, increasing the sound insulation of rooms.

The size of all bricks produced by different manufacturers has established standards: the width and length of the product does not change and is 120 and 250 mm, respectively, the thickness is presented in 3 versions:

single - 65 mm;
one and a half - 88 mm;
double - 138 mm.

From an aesthetic point of view, single brick masonry is the most attractive. One and a half and double thickness of the product contributes to the simplification and acceleration of the process of housing construction. In addition to this, there is a significant savings in the consumed solution.

Masonry methods

To calculate the amount of material needed, the masonry method is of paramount importance. The main types of solid masonry are represented by the following options:

The thickness of the half-brick wall is 12 cm. This method is used exclusively for internal partitions.
A wall of 1 brick has a thickness of 38 cm.
51 cm - wall standard in 2 bricks;
The wall thickness of 64 cm indicates a laying of 2.5 bricks.

The walls of housing are subjected to loads in three directions: for compression, sideways rotation or displacement. In the first case, the vertical forces from the structures above tend to flatten the wall. In low private houses, these loads are small and the side surfaces have a sufficient margin of safety for compression. Rotating and horizontal impacts result from ground pressure on the basement wall or increased crosswinds. Such loads tend to move the wall section from its place. Housing with thin walls is at risk of cracking or even breaking. To ensure a margin of resistance to displacement forces, an increased thickness of the outer side surfaces is included in the design calculation. Given the climatic features of the Russian regions, the most acceptable is the laying of 2 or 2.5 bricks.

Method of calculation

There are two main options for determining the amount of bricks needed for housing construction:

the thickness of the connecting seams is not taken into account;
taking into account the size of the mortar joint, which ranges from 5 to 10 mm.

The calculation according to the first option usually leads to the formation of excess building materials. The second option is more economical, but 10-15% is added to the result in case of possible losses during construction.

We will give the calculation procedure using an example with specific data:

it is planned to build a 1-storey brick house 9x10 m, 3 m high;
laying of external walls in 2 bricks, 1 door 1x2 m and 4 windows 1.2x1.5 m are provided;
a single brick is used, the thickness of the mortar joint of the outer side surfaces and partitions is 7 mm;
internal partitions in half-brick, two 10 m long, one - 9 m;
partitions have 5 doors 1x2 m;

First of all, the amount of material for the outer side structures is determined. The calculation algorithm includes the following steps:

Perimeter of load-bearing walls: (9+10)x2=38 m.
The total area of the outer side structures: 38x3=114 m 2 .
The total area of window openings and doors: 4x (1.2x1.5) + 1x2 \u003d 9.2 m 2.
Net masonry area of the outer walls: 114-9.2 = 104.8 m 2.
To calculate the amount of building material in 1 m 2, we determine the area of \u200b\u200bthe end part of one product: 0.12x0.065 \u003d 0.0078 m 2, respectively, in 1 m 2 there will be 1 / 0.0078 \u003d 128 products. Taking into account the laying method, the value doubles and it turns out 256 pieces per 1 m 2.
For the construction of load-bearing side surfaces, you will need: 104.8x256 \u003d 26829 copies of the product.

Similarly, the amount of material for internal partitions is calculated:

Total area of internal structures: 2x(10x3)+9x3=87 m2.
The area of internal doors: 5х1х2=10 m2.
Net area of partitions: 87-10=77 m2.
Area of 1 product (spoon part): 0.25x0.065 \u003d 0.01625 m 2.
Quantity in 1 m 2: 1 / 0.01625 \u003d 61.5 pieces.
For all partitions: 77x33.3 = 4736 pieces.

Determine the total amount of material for the outer and inner walls: 26829+4736=31565 pieces.

In the second option, when calculating the area of a brick, we add the value of the mortar joint:

For external walls: (0.12+0.007)x(0.065+0.007)=0.00914
Quantity in 1 m 2: 1 / 0.00914 \u003d 109.4 pieces, taking into account laying in 2 bricks: 109.4x2 \u003d 219 pieces.
Total quantity for exterior walls: 104.8x219=22951 pieces.
The area of the spoon part of the brick for internal partitions: (0.25 + 0.007) x (0.065 + 0.007) \u003d 0.0185 m 2.
Quantity in 1 m 2: 1 / 0.0185 = 54 pieces.
Total quantity for internal partitions: 77х54=4158 pieces.
Total for exterior and interior walls: 22951+4158=27109 pieces.

The results of calculating the total area of the outer side surfaces allow you to purchase insulation, if it is provided for by the project. If you do not want to make calculations on the number of required bricks on your own, an online calculator will come to the rescue.

Nowadays, individual construction is developing at an impressive pace. Despite the abundance of modern materials, brick remains the most popular in the construction of a private house. It is still valued for its environmental friendliness, strength and durability. Often, the owners build their own house on their own. And if you have a house project, then the next important step at the stage of its construction will be the calculation of the required amount of materials. You can calculate how much brick you need for a house yourself without using special building calculators on the relevant sites. In our article, we will look at how to do this using the example of a 100 m² house.

Material consumption depending on the dimensions

Before you calculate how many elements are required for a house of 100 sq.m., you need to decide on the thickness of the outer walls. So, for a square house measuring 10x10 m with a thickness of enclosing structures of two stones, much more material will be required than for the construction of a building of the same size with a masonry thickness of one stone.

Important: usually the outer walls are made 380 or 510 mm thick with insulation from the outside or 640 without insulation. The choice of their thickness is made based on the characteristics of the operation of the building and the climatic conditions of the region.

In addition to the thickness, the size of the block itself also affects the number of bricks. So, you can build a house from the following wall elements:

a single stone has dimensions of 250 mm x 120 mm x 65 mm;
one and a half elements for masonry - 250 mm x 120 mm x 88 mm (they can be hollow and solid);
double brick is distinguished by the following dimensions 250 mm x 120 mm x 138 mm.

When choosing a size, it is necessary to take into account the thickness of the enclosing structures. If you need to make a house as quickly as possible and the dimensions of the building envelope allow, choose larger blocks, so you will save on mortar and speed up construction.

Tip: it is believed that with the use of double stone, it is more difficult to get a beautiful facade of the house, and it is also technically more difficult to perform. However, in this case, it can be advised to use a beautiful cladding at home.

Many builders use a simple table that makes it easy to determine how many bricks are needed per square meter of masonry. You may also need such a table, so we provide data from it (the number of bricks is given in brackets, taking into account a 10 mm seam):

To perform 1 m² of masonry with a thickness of 120 mm, that is, a stone floor, you need 61 (51) single blocks, 45 (39) one and a half products, 30 (26) double elements.
For 1 m² of construction with a thickness of 250 mm, you need 128 (102) single, 95 (78) one and a half and 60 (52) double blocks.
For one square meter of enclosing structures with a thickness of 380 mm - one and a half bricks, you need 189 (153) single elements, 140 (117) one and a half stones, 90 (78) double blocks.
An area of \u200b\u200b1 m² with a thickness of 510 mm, that is, in two bricks, can be laid out with 256 (204) single, 190 (156) one and a half or 120 (104) double elements.
For a square meter of masonry 640 mm thick, 2.5 bricks will require 317 (255) single blocks, 235 (195) one and a half stones or 150 (130) double elements.

Doing our own calculations

Now, knowing how many blocks you need to complete a square meter of masonry with a given thickness, you can calculate how many bricks you need per house. You can use a simple home calculation, which involves a number of calculations:

To find out how many bricks per house you will need, you first need to find the perimeter of the house. Since we use a specific example for calculation, namely a house measuring 10x10 m, then its perimeter is 10+10+10+10=40 m.
Now we need to find the area of all external building envelopes minus doorways and windows. Suppose the floor height of the house is 3 m, the wall area is 40x3 \u003d 120 m². If your house has two or three floors, then the resulting number must be multiplied by 2 or 3, respectively. Next, you need to find the area of \u200b\u200ball openings and subtract it from the total area. For example, 120x2-16=224 m².

Important: if your house has a pitched roof, then do not forget to take into account the surface of the gables when calculating the area. Usually they have a triangular shape, so to find the area, it is enough to multiply the height of the pediment by the width of the wall, for example, 5: 2x10 \u003d 25 m². If there are two gables, we multiply the resulting number by two: 25x2 \u003d 50 m².

Next, to find how many bricks you need per house, you need to multiply the total area of the external building envelope, minus openings, by the tabular value of the number of bricks, which you can determine by the width of the wall and the dimensions of the stone. Suppose that the thickness of the walls will be 2 bricks, and we are going to carry out the masonry from a single block, which means that we need 204 elements per square meter, taking into account the thickness of the seam. The total area of the walls, taking into account the gables, is 224+50=274 m². We multiply this number by 204: 274x204 = 55896, that is, approximately 55900 pieces. So many stones will be needed to build a two-story house with gables of 100 m².

Tip: if you need to find the number of facing bricks, then we multiply this area by 51 - facing the floor of a brick made of a single stone, we get 274x51 = 13974 stones.

But it should be understood that we only found the number of bricks for building a box at home, and besides this, you will need elements for the installation of internal load-bearing walls and partitions. We perform their calculation in the same way, that is, first we find the area of \u200b\u200bmasonry with a thickness of 120 mm and multiply by the tabular value for the structure in the floor of the block, depending on the element used. We also find the area of walls with a thickness of 250 and 380 mm and calculate the need for material. Adding all the values found, you will find the total number of wall stones that you will need to build a house.

Attention: after determining the total number of elements, 10% of the margin must be added to this value, because the blocks may be damaged during transportation. And so you will definitely be sure that you have acquired all the necessary material.

Other payment methods

However, the obligatory calculation of bricks can be done in another way, if you know how many elements of a certain size are required to complete one cubic meter of masonry. To do this, you can use ready-made values (values are given in brackets, taking into account the seams):

To complete a cubic meter of masonry from a single product, you will need 512 elements without taking into account seams or 400 blocks, taking into account a seam 10 mm thick.
The same amount of masonry can be made from 378 (302) one and a half bricks.
If you use a double element, then you will need 242 (200) stones to complete a cubic meter of masonry.

First, we find the total surface area of the house minus all openings and do not forget about the gables. How to do this correctly, we described in detail in the previous paragraph. Thus, we know that the area of the outer wall structures of our house measuring 10x10 m is 274 m². This number must be multiplied by the thickness of the external building envelope (the value must be in meters). Suppose that we will make walls with a thickness of 510 mm, which means we get: 274 * 0.51 = 139.7 m³.
Since we will lay the masonry from a single stone, according to the tabular values for 1 m³, we need 394 elements, taking into account the seam. Thus, we can find the total number of bricks for building a box at home: 139.7 * 400 = 55880 pieces. As you can see, this number is not much different from what we found by doing the calculations in the previous way.
We find the number of facing bricks as follows, we need to multiply the area of \u200b\u200bthe external enclosing structures by the thickness of the facing (1 brick): 274 * 0.12 \u003d 32.88 m³. Further, the resulting number must be multiplied by the number of products in a cubic meter of masonry, since we will use single elements for cladding, we get the following number: 32.88 * 400 = 13152 pcs.
Similarly, we calculate the need for bricks for the implementation of internal load-bearing and non-bearing wall structures, as well as partitions. To do this, you need to find their total area with the same thickness. Multiplying the resulting value by the thickness in meters, you will get the number of cubes. So we find separately the volumes of wall structures with a thickness of 120, 250 and 380 mm. After that, all the numbers obtained can be added up and multiplied by the number of bricks in a cubic meter of construction, which we find, taking into account the dimensions of the stone used.

Facing your own home always begins with calculating the cost of work, it’s understandable, it’s always a costly pleasure, but in order to bring everything into one estimate, we need to know how to calculate the amount of facing bricks per house.

You can do this in two ways:

On one's own. Having calculated all the necessary values, taking into account all the nuances of the walls.
With the help of special calculators, in which you just need to “drive certain data.

We consider the facade and walls of the house

Let's immediately decide that we are going to the whole house, and not just its facade. So it will be easier to visually and by example show how the calculations work, and from what moments we will move back.

For an accurate calculation, we will need two quantities:

Size, dimensions of the material used.
The size of the patch. In this case, it is a little difficult to guide it accurately, but we will start from the average thickness.

The standard size of stone used in building cladding is 250*120*65mm, we need the length and height, so we take the values 250*65mm. We will try to reduce the size of the stitching to the denominator - 10 mm, this is the best option for masonry.

Important! It cannot affect the total amount of material in any way, so this indicator should not even be considered.

Standard sizes lead us to 51-52 pieces facing material in 1 square meter. In principle, by entering this data into the calculator for calculating facing bricks for a house, everything will be calculated instantly, but this will be the total area of \u200b\u200bthe walls and the total amount of material.

And here's the thing, the walls of any house are not only a solid surface, and we will have to count everything with our own hands, based on the fact that there are dimensions:

Window openings. They are not always standard, and the shape and area of \u200b\u200bsuch an opening may be different on different sides of the building or on different floors, this will also have to be taken into account immediately when calculating.
doorways, we have at least two doors, entrance and back, plus, possibly, a balcony.

Knowing how to calculate the amount of brick for facing a house, and knowing all the parameters of the walls, we get the final figure. Here you can immediately make a small footnote, the total area of windows and doors can be from 20% of the entire quadrature of the walls of the building.

architectural nuances

We often say that facing material must be bought with some margin. It is clear that the most obvious reasons are stone breakage, or deformation, improperly behaved masonry.

However, there is another reason, these are architectural nuances that look great on paper, but are sometimes quite difficult to work with.

Even if the base of the walls is a double silicate brick M 150, the material is unpretentious and simple, even they can make small ledges, parapets, extensions, that is, change the even plane of the walls.

By repeating the contour, we will have to take all this into account in the calculations, and even if very small changes, they will still require an additional brick.

Windows and rustication of corners

So, we figured out the walls, now let's move on to the window openings, because we can't leave them “naked”.

And for the rustication of the corners of the house and for framing the window opening, one simple formula can be used.

In it, the calculation of facing bricks is based on the length of linear meters of openings and its division by the height of the facing material.

We explain. First, we measure all openings. Once again, it reminds us of linear meters, that is, everything here is just plus. Next, we have the height of the stone, this is always the standard size, even if building bricks are used, 65 mm.

In addition, we add the thickness of the seam, 10 mm, and we get the following formula 1m / (0.065 + 0.01). According to calculations, this is 13, 33 bricks per 1 linear meter.

We carry out exactly the same calculations when we need to calculate the rustication of all corners, by the way, there may not be 4 of them.

Subtotal

We can reduce our calculations to several main positions, these are:

52 pieces per square meter of wall.
14 pieces per linear meter of windows and corners.
The working surface of the walls.

Knowing all the parameters, we can easily come to the necessary numbers.

Additional calculations

If we have a terrace, for example, or a canopy, an open-type veranda, then there are decorative columns, pillars, which are also included in our calculation of the number of facing bricks per house, as they should be in the same style direction as the facade.

A column measuring 38x38 centimeters, as the most common for a veranda and a canopy, will require us to have 4 in one row with a standard size 250*120*65 .

Again, we take into account in our calculations the thickness of the seam, which we try to keep within 10 mm. In general, the instructions are quite simple.

It is 118 bricks that we need for one column. Actually, knowing this figure, we further consider how much it will take for the rest of the columns.

There is one nuance here, which depends on the size of the pillar, if everything is simple with the walls, and there can be only one option for both calculations and masonry, then we can lay pillars in several types.

Advice! Do not pay attention to the mismatch in the size of the facing bricks. Just for walls, you can use standard dimensions, and for columns choose a torn corner brick, its dimensions are 220 * 90 * 65. In this case, the number of pieces of material will not change, only the size of the column itself.

Conclusion

Such close attention to the calculations is due to the fact that the price of the material is not the cheapest, and it is necessary to understand how much material to buy at once. This is where color plays an important role. We have noted more than once that bricks from different purchase lots may differ in color.

Conclusion

Knowing how to calculate the facing brick for a house, we can independently start the rest of the work, and keep the result in mind when choosing a material at a cost. The price per brick is always per piece. In the presented video in this article you will find additional information on this topic.

Happy building!

Let's say you decide to build a house with your own hands. However, before construction begins, it is imperative to calculate the amount of building material. Currently, building bricks are quite expensive, an accurate calculation will significantly reduce your costs.

A preliminary calculation is necessary in order to be able to purchase the material of one batch. This will avoid trouble with different shades in different batches.

Note! The use of building material of different batches will not have the best effect on the appearance of your building. This is due to the fact that it is practically impossible to produce an artificial stone from clay of the same color in different batches, since both the composition of the clay and the firing temperature may differ slightly.

Below is a table that shows the correspondence of these parameters.

Table 1

Calculation procedure

Stages

The following steps must be followed:

To correctly calculate the number of bricks per house, you need to know its dimensions, such as length, width and height.

After calculating the perimeter of the building, the resulting number is multiplied by the height. As a result, we get the area of the constructed surface.
Next, you need to calculate the area of \u200b\u200bwindow and door openings, subtract the resulting number from the total area.

It is also necessary to decide on the choice of one or another type of stone, which happens:

Single. It has dimensions of 65 by 120 and 250 mm;

. It has dimensions of 88 by 120 and 250 mm;

Double. It has dimensions of 138 by 120 and 250 mm.

Using one-and-a-half or double silicate bricks M 150, you can build walls much faster, but you should be aware that this may worsen the appearance of the building. The price of a double and one and a half is of course higher than the price of a single. Many people think that a single one looks much prettier, but the idea of \u200b\u200bbeauty is a rather controversial issue.

To make a more accurate calculation, you need to add to the height of each stone 10 mm. This is how much the thickness of the seam is. You should also add about 5% per fight.

table 2

Type of masonry, stones	Stone size	Including seams, pcs.	Excluding seams, pcs.

Note! Quantity data in table 2 are given without taking into account door and window openings, the dimensions of which are individual.

This instruction will allow everyone to understand how to calculate the number of bricks on their own. There is nothing difficult in this.

Simple example

An example of calculating the material for the construction of a house 12 by 12 m, having 2 floors:

Determine the perimeter of the house. Add up its length and width. We get: 12+12+12+12=48 m;

We count the area. To do this, multiply the perimeter by the height. Let's say that the height of each floor of our house will be 3 m, the total height is 3 + 3 = 6 m. As a result, the area will be 48 * 6 = 288 m 2 ;
The next steps depend on what kind of masonry you will perform. Let's say we perform laying in 2 stones and facing in 0.5 stones. According to table 1, we see that the wall thickness in this case will be 640 mm. According to table 2, we see that in this case there are 204 pieces per 1 m 2 ;

Let's count the ordinary stone. For this, the number of pieces per 1 m 2 multiply by the area of the walls. We get: 288*204=58752 pieces;
Let's calculate . According to table 2, it can be seen that they reach 1 m 2 only 51 pieces. As a result, we have: 288 * 51 = 14688 pieces.

Internal partitions are calculated in a similar way. You can make several calculations with different types of masonry and decide on the best option.

An online calculator will help you understand how to calculate the amount of bricks for building a house. It is a specially designed program that performs all calculations automatically. You only need to enter the dimensions of the building and select the type of masonry.

Conclusion

It is not at all difficult to calculate how much material is needed, even by purely mathematical methods. Always try to complete all the necessary miscalculations first before you start building a house. This will allow you to rationally spend your money and reduce the occurrence of unexpected expenses.

It is possible to estimate how much it will cost to build a house only when calculating the consumption of the main material and auxiliary substances. All future owners, according to the available data, make estimates and prepare for the purchase of building materials. A non-professional can help in obtaining such an assessment with a special calculator for calculating bricks or blocks for building a house. A simple introduction system allows you to easily understand the operation of the online application.

How to calculate the number of bricks to build a house?

First of all, you need to enter the parameters of the house: the perimeter indicator and the height. Corner laying in most cases does not require a special consumption of material, therefore, only the sum of the length and width of the building should be indicated in the online brick calculator. The height can be any, but you need to remember about the possible construction of an attic, where additional building material consumption will be required. The calculator calculates for buildings in the form of parallelepipeds.

The number and parameters of doors are especially important when creating not only the main entrance, but also the exit to the backyard. It should be noted that the application will calculate the consumption for products with identical parameters. If the dimensions of the doors are different (the entrance doors will be made to order), you should indicate the height and width of the smaller one.

When installing different windows, you must also select medium and small options and specify them. Excess material after such calculations may be useful for the construction of an extension. And the disadvantage is reflected in the need for additional purchases, which is not convenient for all owners. That is why in the calculator for calculating bricks for building a house, it is necessary to take into account all the nuances. This will allow you to get an approximate result with a minimum error.

Entering data on masonry and the main building material

The exact calculation of blocks or bricks per house in the online calculator is based on the dimensional parameters of one unit and the amount of mortar used. It is important to indicate the thickness of the masonry, which will allow you to find out exactly how many bricks or blocks you need to get it. Further, the previously summarized parameters of windows and doors will be subtracted from the total number (compiled according to the parameters of the building itself). The end result will indicate the approximate amount of building materials required to build a brick house.

Users should remember that the brick calculator gives the result required to build a box house. Any stylistic additions, completion of the attic, the creation of small extensions or thickening in the basement area must be added separately.

In addition, you need to know how to calculate the number of facing bricks per house. It is this material that is used by most developers and allows you to additionally protect the building, give it an attractive appearance. The calculation of the cladding is made according to the thickness of one element and indicates the additional amount required for external finishing work.
