Building a house from foam blocks

Before calculating the cost of materials and making an estimate, it is reasonable to talk about the material itself from which construction is planned. The material in question is classified as lightweight concrete blocks.

Lightweight building blocks are divided into three types of building materials:

• foam concrete- the composition of this material includes two elements - a cement mixture with the addition of sand and a chemical reagent with which foam is formed. In order to give the resulting solution the desired shape, it is poured into special molds in which the process of heating it takes place. This material is easy to manufacture, so its production can take place during the construction process, directly on the construction site.
• Aerated concrete or cellular- this material differs in its properties from foam concrete, its hardening requires high humidity and high temperature. The advantages of this material include the fact that only environmentally friendly materials are used for its manufacture. The composition includes: water, sand, lime and cement. The structure of such material will be durable and strong, and the material is not subject to combustion and is well machined. Aerated concrete is on the same level as wood in terms of its environmental performance.
• Expanded clay concrete- the most common type of lightweight concrete.

This material is very competitive in the modern construction market. The most important advantage of the material is its low weight; during construction, less time is spent on work due to the convenience of working with light material.

In addition, aerated concrete houses are also popular because of their cost-effectiveness during operation. Profitability lies in the fact that heating such a house does not require a lot of energy, which cannot be said about brick houses.

Also, a house made of aerated concrete can be built independently, without resorting to the help of specialists. And the delivery of the material will not cause great difficulties for buyers.

If we consider the material from an environmental point of view, we can say for sure that it is environmentally friendly. It does not emit toxic substances, gases and suspension. Thus, the material is completely safe for the environment.

When laying the material, there will also be no difficulties. Due to the fact that it is of the correct shape, there will be no difficulties with the seams, and they will not be more than 4 mm. Aerated concrete retains heat well, so when building from it, there is no need for thick walls.

Pricing policy when building a house from aerated concrete

The price of the building will depend on two indicators - the density of the material and the thickness of the walls. Accordingly, with an increase in parameters, the price will increase, and, conversely, with a decrease, the price will also be lower.

On average in Russia, the project of such a house with an area of ​​350 square meters is 30 thousand per square meter. And since the material is easy to work with, there is no need to hire qualified specialists to lay it, and this will significantly reduce construction costs.

The type of foundation that is used in the construction of foam blocks and aerated concrete

Before starting construction, you need to choose a place for the building. With the help of official documents, it is necessary to find out the type of soil and the depth of groundwater, and using these data to determine what kind of foundation is needed for the selected area.

If the type of foundation is chosen correctly, then the structure will stand for a long time, and will not deform and collapse. The price of the structure will partly depend on the type of foundation chosen.

Construction stages

1. The first step in building a house is laying the foundation.
2. The second step is building walls. Before building walls, it is necessary to make waterproofing so that the house does not freeze through.
3. The third step is the reinforcement of aerated concrete. The mesh is laid between the finishing layers to prevent deformation of the structure.
4. Next is the installation of floors.
5. Construction is nearing completion interior and exterior decoration.

Foam concrete masonry

Recently, such material as foam concrete has become very popular. The reason for this was that this material is hygienic and has a low cost. Unlike other concrete materials, it has good vapor conductivity and capillarity.

Foam concrete differs from aerated concrete in that during laying, dimensional errors may occur, this is due to the technology of its production. It is for this reason that foam concrete is laid on a sand-cement mixture.

In the middle lane, when building a house, it is necessary to build one wall of foam concrete, which should be about forty centimeters and covered with a glass wool heat shield on the front side. The thickness of the heat shield should be five centimeters.

If we talk about foam concrete from a safety standpoint, then it is significantly ahead of brick materials in terms of its qualities.

Finishing of a building erected from foam blocks can be done at least six months after the completion of construction.

It is necessary to do this due to the fact that the foam concrete is reduced in size and because of this the finishing layer is destroyed. For the finishing layer, it is best to use drywall.

When finishing a foam concrete building from the outside, it is necessary to choose a material that will allow vapors to pass from the premises of the house.

Important! The exterior decoration of the building from foam blocks cannot be done using a film-forming composition, as well as plastering.

brick facade

A fairly optimal option for decorating a building is a face brick. Brick is the oldest material used to build houses.

The use of brick was due to the fact that it is strong enough and has little water absorption. Brick is also suitable for the implementation of various design ideas. It comes in various shapes and textures.

At the moment, the following forms of bricks are produced:

• rectangular;
• rounded;
• wedge-shaped;
• bevelled.

If we consider invoices, we can designate the following:

• corrugated;
• rough;
• smooth;
• chipped.

With such a variety of shapes and textures, it is possible to embody any design idea and fantasy.

Slab concrete foundation with monolithic concrete strip

The slab foundation is a reinforced concrete slab, which is installed along the outer perimeter of the walls of the building.

There are two options for installing a slab foundation:

• Unburied;
• Buried.

If the slab foundation is placed according to the second option, then it also acts as a foundation for the building. Foundation walls are placed on this foundation, and an underground floor is formed. The method of continuous concreting for the vertical parts of the foundation is used for shallow groundwater. In this case, it is necessary to carry out waterproofing measures.

If the soil is unstable or close to groundwater, then a non-recessed slab base is used. Such buildings are appropriate if you do not need a basement or cellar. This slab base is suitable for small buildings.

Important! There is a possibility of freezing of the foundation if the foundation slabs serve as the basis for the floor of the room and are above the freezing point of the ground.

To prevent freezing of the soil, it is necessary to make thermal insulation. Insulation is made under the base plate around the entire perimeter of the room. The strip of insulating material must be at least one hundred centimeters.

A good option for insulating material is a heat shield, which is made from extruded polystyrene. In terms of its properties, such a screen is better than other heaters, such as: glass wool, expanded clay granules and granulated foam, as it does not absorb moisture well and retains its thermal insulation properties for a long time.

Ceilings from prefabricated reinforced concrete slabs

Reinforced concrete slabs are usually used to create interfloor floors in brick houses. Plates are applied hollow.

The use of such plates is due to their positive qualities. They are well soundproofed, unlike reinforced concrete floors.

Ceilings are made according to a special technology, in which the initial tension of the concrete reinforcement is made, and the ceilings become more load-bearing, in contrast to those that are immediately made at the construction site.

Plates produced using industrial technology guarantee the specified performance properties and have a low price. Such ceilings are installed much faster.

Steel tile roof

Steel shingles are currently the most common roofing material. For the buyer, its acquisition will not create any difficulties, since it is produced by a large number of manufacturers. To install the roof, a solid frame is erected, which consists of a sheathing layer and truss elements.

A tile roof can be made with a different number of spans. For a private house, a two or three-span system is most often used. In such a system, internal load-bearing walls are erected, as well as rafter beams at an angle.

The base on which the rafters are attached is called Mauerlat. It is necessary to make an interval between the rafter beams, which varies in the range from 60 to 90 centimeters, if the thickness of the beam is 100 * 150 mm.

In the roof, it is necessary to make channels for ventilation, which will remove moisture from the premises of the building. The number of such channels depends on the area of ​​the roof and is 1/100.

Wooden windows with double glazing

Recently, wooden windows have become popular again. Now they are not made with inset glass, but, like plastic windows with double-glazed windows. The material for the manufacture of wooden windows is a glued timber profile. It is decorated with double glazing and equipped with modern fittings.

Wooden windows have a number of advantages, which are worth mentioning:

• The service life of such windows exceeds the service life of plastic ones;
• The windows have beautiful geometric shapes;
• Good at retaining heat indoors.

Since the window is equipped with modern fittings, there are several options for opening it to get air exchange with the outside world.

The most common options for air exchange when opening a window:

• Micro;
• slotted;
• Winter ventilation.

Existing ventilation options prevent condensation on windows in the cool sides of the glass or on slopes.
