The project of a country house from foam blocks 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.

Why foam blocks are good

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.
  • Inexpensive.
  • 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:

  • Cannot bear heavy loads.
  • Slowly gain strength, and at the same time shrinkage will occur, and as a result, there is a possibility of cracking.

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.

Details

Foundation

As a rule, when building a country house, a shallow strip foundation is used. It can be done in different ways.

  1. Of assembly blocks that are laid without joining, freely.

  2. From blocks, with a reinforced belt device under the blocks and above them.
  3. Of rigidly connected blocks of reinforced concrete.
  4. Made of monolithic reinforced concrete.

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:

  • The project of a country house from foam blocks Stake out.
  • Trench development - if the soil does not crumble, then the trenches will be arranged in the width of the base, and from the wall they will act as formwork.
  • Next, backfill 0.

    3 meter sand and gravel cushion in layers with compaction of each layer, and the thickness of each layer should be 10 cm.

  • This is followed by laying the waterproofing material on the walls and bottom of the trench.
  • The next step is to install the formwork under the above-ground part of the base (that is, the basement).
  • Installation of fittings.
  • Pouring concrete.

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:

  • Correctly selected proportions of the components in the concrete mixture.
  • In no case should there be air bubbles in the concrete (that is, voids), and in order to achieve this, usually a vibrator is used for this or concrete is bayonetted with a metal rod.
  • There should be no breaks during pouring.

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.

Wall masonry

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.

  1. Find the highest point of the base with the level. The first block will be placed in the corner closest to this point.
  2. Next, place blocks in all other corners.
  3. Between the blocks of the corner type along the outer edge of the wall, pull the cord0 mooring. It is required to fill in the first row.

  4. If any irregularities appear in the masonry, they will be removed with a sanding board or plane. Dust and dirt are removed with a brush.

Let's look at the second step.

Reinforcement

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.

  • The project of a country house from foam blocks Using an angle grinder, you need to make grooves measuring 4 * 4 cm at a distance from the edge of the blocks at least 6 cm.
  • Remove dust from the grooves and then moisten with water.
  • Cement mortar must be placed in the groove at half the total depth.
  • Place a rod that has been dampened with water.
  • The recess must be completely filled with mortar.

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.

Mortar

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.

Cutting blocks

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.

Load-bearing walls

After laying the first row, you need to wait 1-2 hours until the mortar has set.

After laying the walls will continue.

  • Insert corner blocks, align.
  • Stretch the dock.
  • The row must be filled with foam blocks.
  • Irregularities are eliminated with a sanding board or planer.

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.

Partitions

Now, one more thing:

  • On the load-bearing wall surface, you need to mark the junction of the partition.
  • In such a place in the seam it is required to lay out flexible ties (anchors) made of stainless steel.

    One end is in the load-bearing wall, and the other in the seam of the partition.

  • Anchors must be secured with nails.

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.

  • Mark the cuts on the foam block.
  • Saw through the grooves, break off the inside with a construction hammer.
  • Hollow blocks in the form of a letter P, which is inverted, are laid over the opening on wooden supports. These can be beams or boards, and the supports can be nailed to the side opening walls.
  • Reinforcement must be laid inside the cavity 1.

    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.

Roof

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.

Outdoor finishing

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:

  • Wall cladding, which will be installed with a gap (decorative panels, siding, lining with a bar imitation).
  • Decorative type of plaster.
  • Composite type panels.
  • Stone of artificial and natural origin.

  • Staining with silicone paints and varnishes.

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.
