Construction of an extension to the house of foam blocks

Foam concrete is one of the latest construction developments. This material has many indisputable advantages and is very popular. Its cellular fractional structure is characterized by low thermal conductivity, which allows not to spend money on additional insulation. Low weight and dimensions exceeding the size of a brick or sawn stone, (standard foam block size - 600x300x200) allow you to significantly save sand and cement during construction.

Due to its unique porous structure, foam blocks have good sound insulation. The same properties create the effect of the "breathable" wall, which protects the extension from the occurrence of condensate, provoking the formation of mold or fungus. Environmentally friendly natural components are used to produce blocks from foam concrete.

Planning and drawings extensions from foam concrete to the house

First, decide on the place of extension, its size and height. It is important that the roof of the facility is a bit below the roof of the house.

1. Provide and plan the communications runs. It must be done at the initial planning stage, otherwise you will come across the problem of their gasket after the construction of the walls.
2. It is also required to envisage the possibility of a deformation seam in the splicing places of an extension and the main structure.
3. The doorway in the extension can be equipped in the place where the window is located on the outer wall of the house, and can be cut into the bearing wall. In this case, consider external loads.

Foundation arrangement for construction

We build an extension to the house from the foam blocks with your own hands is easier than from traditional materials. The foundation for an extension of foam blocks is made by the belt filling method from concrete or from the elements of the future design.

1. The depth of the base depends on the height and mass of the extension. For a small structure, it is sufficient to dull 50 cm deep in the perimeter and the width to half a meter. At the time of bookmarking the foundation of foam blocks, it is important to pay attention to the insulation and waterproofing of the underground part of the structure. The foundation is subject to influence of groundwater and temperature differences.
2. Having absorbed in the material moisture in winter can freeze and contribute to the destruction of the base, and the condition of the walls depends on its strength. At the time of the start of construction, on the zero cycle, work on insulation and waterproofing begins. For insulation, polystyrene foam, minvatu, penplex and other materials are used.
3. Laying heat-insulating plates is performed directly at the time of waterproofing. The fusion foundation is deceived by water-repellent mastic. The heat insulation plates covered with hot, about + 70 ° C, bitumen are attached to it. Bashed them additionally there is no need. When dripping the trenches, the Earth will press the insulation to the base. Elements of heat-insulating material should perform above the ground level by about 50 cm.
4. There is another type of foundation insulation - polyurethane foam. This is a new and more expensive means, but its application solves the issue of maintaining the temperature and waterproofing at the same time. Through a special machine, a polyurethane is sprayed with a layer of up to 5 cm on the foundation surface. The coating of such a thickness corresponds to 12 cm of conventional polystyrene foam.

These materials successfully cope with the task of insulation and waterproofing at home and prevent the occurrence of the bears of cold, which, in turn, protects the living room from the occurrence of mold and fungus on the interior walls.

Erecting walls for an extension of foam blocks

On the frozen and high-end perimeter of the base, it is possible to packeroid or a scheduling. Such a layer, laid in terms of the level of "Rosa", prevents the penetration of moisture above the floor level.

1. When laying a first row of a wall of foam blocks, a conventional cement solution is used. Construction, as usual, should be started from the corner. 3-4 horizontal rows of foam concrete blocks are laid out and the time is given to them to grab. This is from an hour to three to four, depending on the cement adhesive used.
2. In places of adjoining an extension to the wall of the house, binding mortgages are driven. For them, cropping a metal rod or reinforcement with a diameter of 8 - 10 mm and about 30 cm with a length of a rod is driven into the wall to half the length, and its protruding part should definitely fall in the seam between the foam concrete blocks.
3. When the walls are erected, constantly check the horizontal of the rows and the vertical structure of the design and plumb. The last row of the walls are made taking into account the laying of rafting beams for the roof. It is possible to make a two-tie or single-table, as well as a cascade roof of an extension.

Outdoor and interior wall decoration from foam concrete

1. Foam concrete itself has all the necessary technological properties to build any structure. When creating attachments from foam blocks, the outer walls need only in decorative cladding.
2. The outer walls can be placed, the solution sticks well to blocks from the foam concrete and during the operation of the building does not appear. A good option is to separate the construction of siding. It all depends on the outdoor coating of the structure will be combined in style with the main structure.

Interior decoration is made as in an ordinary house. A plaster layer is applied, which then puts out under painting or wallpaper. Consider the options for internal design by plasterboard or wooden panels.
