Construction of a country house from foam blocks
Country houses from foam blocks have a small weight, and they are also fireproof. Due to the huge block size and precise dimensions, erection is carried out at a high speed. You can easily build a house in one summer.
The use of foam blocks in the construction of various buildings guarantees thermal savings and a fast pace of work. A country house made of such material will cost much more than wood, but much less than, for example, brick.
The advantages of building materials such as foam blocks are as follows:
- They have a precise geometric shape, and the dimensions are perfectly kept. For this reason, they can be installed quickly.
- Moisture resistant.
- Over time, their strength will only increase.
- They have a low thermal conductivity, and because of this it is the best material for construction.
- They have a low specific gravity, and therefore they are made with a sufficiently large size, and this has a positive effect on the speed of building walls.
- Easy to handle.
But there are also some disadvantages:
Use high-quality autoclaved foam concrete - it is much less susceptible to shrinkage, and the strength of the material is quite sufficient for building one-story country houses. In this case, it is required to strengthen the upper supporting row by means of reinforcement.
As a rule, when building a country house, a shallow strip foundation is used. It can be done in different ways.
The selection of the method is made depending on the soil qualities, and the version of the reinforced tape is suitable for both planting and also for highly heaving soils. A tape in width is made with an excess of the wall thickness by 10-20 cm, and the depth of laying is up to 60 cm.
The basement can be within 40 cm. By the way, on heaving soils, it is imperative to equip a pillow of frost-free material.
Construction of the foundation
Stages of the strip foundation of the reinforced type with a shallow deepening:
3 meter sand and gravel cushion in layers with compaction of each layer, and the thickness of each layer should be 10 cm.
Now let's talk about how to make the foundation look good.
Conditions for the quality of the foundation
The project of a country house made of foam blocks does not make sense if the base is of poor quality. To build a high-quality foundation, the following conditions must be observed:
After the pouring process, until the concrete hardens, it requires maintenance. It is required to cover it from the sun, water it in hot weather. In cold weather, insulation is required. A roll material for waterproofing is laid on top of the base, but the overlap of the strips should be at least 0. 15 meters.
It should be remembered that the foundation for a foam block house is the main supporting part of the house. For this reason, you do not need to save much on it. An equally important part of the house will be the roof.
Before starting to build walls, it is necessary to check the levelness of the base. The permissible height difference is 3 cm, and if necessary, leveling with a cement mortar is required.
The upper block plane, laid on the surface of the walls, must be horizontal. That is, not just the edges that go along the walls should be horizontal, but also those that go across. Horizontal control is carried out by means of a building level. The position of the blocks is corrected, if necessary, with a rubber hammer.
The first row and its laying
The first row must be laid out especially accurately - the accuracy of the construction of the house as a whole will depend on this.
Let's look at the second step.
The reinforcement is laid on the surface of the foam blocks filling the first row, and then after the laying of each 4th row. A smoothly bent twig is laid in the corners.
Make a monolithic belt at the slab level. It will bind the load-bearing walls along the common perimeter and impart spatial rigidity to the structure as a whole.
For laying a country house from foam blocks it is required to use:
- Cement-sand mortar ...
- A solution of sand and cement with the addition of lime.
- Adhesive composition for blocks of laying walls.
A solution in which there is lime will not set so quickly, and also has excellent plasticity. The adhesive composition makes it possible to make thin seams, and it has a fairly liquid consistency and does not set for a long time.
As a rule, it is impossible to lay walls using only whole blocks.
We have to supplement it with cut ones. You can cut blocks with a hand saw, and the cutting line must be drawn with a pencil on two adjacent sides in order for the cuts to be accurate. The cutting surface is leveled with a planer or sanding board. A smooth surface is required for excellent adhesion between the block and mortar.
After laying the first row, you need to wait 1-2 hours until the mortar has set.
After laying the walls will continue.
The ligation of the seams should be at least 10 cm, and the minimum length of the blocks (outermost) - 11. 5 cm. Internal load-bearing walls should be connected with external ones by means of dressing.
Now, one more thing:
One end is in the load-bearing wall, and the other in the seam of the partition.
Anchors must be inserted into the load-bearing wall surface every 1 row. It is allowed not to fix them with nails, but simply press them into the solution.
Window and door openings
Jumpers for floors can be purchased from the factory, and can also be made of hollow-type foam sides, which look like the letter P in cross section.
2-1. 6 cm, concrete is poured. The supports will remain until the concrete hardens.
Foam blocks can be laid over the opening and on metal corners.
For arranging floors in a country house from foam blocks, the construction of which is not as burdensome as it might seem at first, wooden beams are usually used.
The type of roof, its shape and design may be different, and its construction is not much different from this type of work in the construction of houses using other building materials. Living in a country house requires you to have your own car. And it definitely requires a garage. To avoid problems in the future, you should find out in advance about the disadvantages of such houses.
Although foam concrete is not soaked to a great depth when exposed to moisture, but the surface layer will absorb it well enough.
For this reason, if the walls are not covered with outdoor decoration, they begin to darken and begin to collapse. In the role of exterior finishing of foam block walls, the following can be used:
Building a country house will be relatively inexpensive, and at the same time building a house will be quite quick. If you have certain building skills, then it is quite possible to make such a house with your own hands.
