The popularity of brick buildings is explained by a number of positive properties of this building material. In the first place is sustainability. Brick houses with the correct laying date will last the last century. And there is evidence for that. Today you can see strong buildings built several centuries ago.

Dense brick perfectly resists the “attacks” of the weather. It does not collapse under the rain streams, does not crack due to the temperature drop and is resistant to both severe frost and burning heat. Immune to stone and sunlight.

In favor of the brick says resistance to biological destruction. In addition, the stone is fireproof. Even with prolonged exposure to open fire, walls are not destroyed. Architects love this building material because it allows you to realize interesting architectural solutions.

Today, not only white silicate and red bricks are produced, but also multicolored, making it possible to create original colored facades. Brick houses look solid, reliable, like a real fortress from a famous saying.

**What does it depend on?**

First of all, the need for **bricks for building** a house depends on the dimensions of the walls, more precisely on their thickness. The thicker the walls, the more building material they will need. The thickness of the walls is determined by the type of masonry. Their variety is limited.

** **

**Depending on the number and location of stones, there are masonry in:**

- half-stones (masonry is used for partitions, since half-stone buildings are not built in half-stone);
- one (masonry is used for partitions, sometimes for garden houses, where there is no heating);
- one and a half (suitable for the construction of buildings in a warm climate);
- two (suitable for the construction of buildings in central Russia, Ukraine, Belarus);
- two and a half (usually used in the construction of private houses and cottages in zone II climatic zone);
- three (now practically not used, but found in buildings from the past, before previous and earlier centuries).

The stones themselves vary in size. According to existing standards, all manufacturers produce building materials of identical dimensions only in length and width. The first parameter (length) is 25 cm, the second (width) – 12 cm. Differences consist of thickness.

**The following thickness dimensions are made for:**

- ankle – 6.5 cm;
- one and a half – 8.8 cm;
- double – 13.8 cm

**Bricks of the same or different types can be used in masonry.** If after construction you do not plan to cover the facade with plaster, then a single brick is most preferable, because it will look great.

Often a single view is used for the cladding and the inside of the masonry consists of thickened (one and a half) or double bricks. The cumulative use of two types usually takes place if you want to save. After all, a double brick in volume is much cheaper than one or a half.

**Special functions**

To correctly calculate the need for a brick for building a house, you need to know its dimensions. Most of the time, newcomers to construction make mistakes and get a much larger amount of building material than they actually need.

The fault is that mortar joints are not taken into account. Meanwhile, the layer of mortar between the bricks is a significant amount. If you miss the number of stitches, the result will differ by at least 20 percent.

As a rule, seams have a thickness of not less than 5 and not more than 10 mm. If you know the size of the base material, you can easily calculate that a cubic meter of masonry is 20 to 30 percent of the volume of masonry mortar. An example for different types of stones and the average thickness of the mortar joint. Practice shows that for one cubic meter of masonry there are 512 individual bricks, 378 thickened or 242 double bricks.

**Taking into account the amount of the solution is significantly reduced: some** bricks required 23% less, that is, only 394 pieces, one and a half, 302 and double – 200 pieces respectively.The calculation of the required number of bricks for building a house can be done in two ways.

In the first case, it is possible to take a brick that is not of a standard size, but with surcharges equal to the thickness of the mortar joint. The second method, taking into account the average consumption of building material per square meter of masonry, is more preferable. The problem is solved faster and the result is quite accurate.

Deviation in one direction or another is no more than three percent. Agree that such a small mistake is quite acceptable. Another example, but not based on volume, but on an area of the wall is a calculation that takes into account the method of laying 0.5, one and a half, two or two and a half brick.

Laying in half-stone is usually done when using beautiful, opposite brands.

** **

**For 1 m2, taking into account the required seams:**

- single – 51 pieces;
- thickened – 39 pieces;
- double – 26 pcs.

**For laying 1 brick per square meter you need:**

- single – 102 pieces;
- 78 thickened;
- double – 52 pcs.

The wall thickness of 38 cm is obtained by laying one and a half brick.

** **

**The material requirement in this case is:**

- single – 153 pieces;
- thickened – 117 pieces;
- double – 78 pcs.

** **

**For 1 m2 masonry in 2 bricks you need to spend the following:**

- single – 204 pieces;
- thickened – 156 pieces;
- double – 104 pcs.

**For thicker walls of 64 cm, builders per square meter need:**

single – 255 pieces;

thickened – 195 pieces;

double – 130 pcs.

**How to count?**

In order to properly perform the operation to obtain the required **number of bricks** for the construction of the house, the work must be divided into several stages. No matter which house it is decided to build: a small low or large two-storey house with an attached garage, a winter garden or a terrace, the principle of calculation is the same. First you need to calculate the area of the outer walls. A similar calculation of the area has been made for interior walls.

Then you need to calculate the part of the window and the doorways. In the project, as a rule, no areas are indicated, but linear dimensions. To calculate the area, you need to use the school’s well-known formula, multiplying the height by the width. If the openings are the same, you can find the area of one opening, for example, a window, and multiply the result by the number of future windows.If the dimensions in different rooms are different, you need to perform the calculations for each separately.

All resulting openings are added and subtracted from the area obtained for the walls. Find out how much brick ends up in a known volume or area, quite easily. For example, 200 square meters. m laying in 1 standard (single) brick goes without seams 61 x 200 = 12 200 pieces, and taking into account the seams – 51 x 200 = 10 200 pieces.

We give an example of calculating the consumption of stones. For example, it is planned to build a two-story brick house. The width of the building is 9 m, the length is 11 m and the height is 6.5 m. The project provides for the laying of 2.5 bricks and an exterior cladding of 0.5 bricks on the outside, and the main wall is made of double bricks. Within the wall thickness of the building is a brick. The total length of all inner walls is 45 m. In the outer walls there are 3 doors 1 m wide and 2.1 m high. The number of window openings is 8, their dimensions are 1.75 x 1.3 m. Inside there are 4 openings with parameters 2.0 x 0.8 m and one 2.0 x 1.5 m.

**Determine the area of the outer walls:**

9 x 6.5 x 2 = 117 m2

11 x 6.5 x 2 = 143 m2

117 +143 = 260 m2

**Doorway area:** 1 x 2.1 x 3 = 6.3 m2

**Area of window openings:** 1.75 x 1.3 x 8 = 18.2 m2

To correctly determine the completely solid surface of the exterior walls, the area of all openings must be subtracted from the total area: 260 – (6.3 + 18.2) = 235.5 m2. We determine the area of the interior walls, taking into account the the fact that the brick walls are only on the first floor with a ceiling height of 3.25 m: 45 x 3.25 = 146.25 m2. Without gaps, the area of the walls in the room will be:

146.25 – (2.0 x 0.8 x 4) – (2.0 x 1.5) = 136.85 m2

**It remains for us to calculate the number of bricks on the basis of the aforementioned consumption per square meter:**

- double: 235.5 x 104 = 24,492 pieces;
- opposite: 235.5 x 51 = 12.011;
- Single: 136.85 x 102 = 13,959 pcs.

The number of units is approximately, rounded to one.

With the same overall dimensions of the house, we calculate by volume. First we define the volume of the walls. For this, the length of one of the sides of the house (for example, a smaller one, 9 meters long) we fully accept it and calculate the volume of two parallel walls:

9 (length) x 6.5 (height) x 0.64 (thickness 2.5 bricks) x 2 (number of walls) = 74.88 m3

The length of the second wall is reduced by (0.64 mx 2), ie by 1.28 m. 11 – 1.28 = 9.72 m

**The volume of the remaining two walls is equal to:**

9.72 x 6.5 x 0.64 x 2 = 80.87 m3

Total cubic capacity of the walls: 74.88 + 80.87 = 155.75 m3

** **

**The number of stones depends on the selected type and is for:**

- single: 155.75 m3 x 394 units / m3 = 61,366 units;
- thickened: 155.75 m3 x 302 pcs / m3 = 47 037 pcs;
- double: 155.75 m3 x 200 pieces / m3 = 31,150 pieces.

As a rule, construction material is not sold individually, but is put on a pallet by the party.

**For corpulent stones, you can focus on the following number in the pan:**

- only – 420 pieces;
- one and a half – 390 pieces;
- double – 200 pcs.

To order a batch of building material residues to determine the number of pallets.

**In our last example, the demand for bricks will be:**

- single: 61 366/420 = 147 pallets;
- one and a half: 47 037/390 = 121 pallet;
- double: 31 150/200 = 156 pallets.

**Tips and tricks**

It is believed that all bricks in size meet the established standards. However, there are tolerances and different batches of products may vary slightly. The structure will lose perfection when using different blocks. For this reason, it is recommended to order the full amount of building materials from one supplier at a time.

Only in this way will the guaranteed material purchased differ in size and color tones (for other brands). The estimated amount should be increased by 5%, due to the inevitable losses during transportation and construction. Correct calculation of the required bricks will avoid unnecessary downtime and save the developer’s finances.
