Rules laying silicate blocks

Rules laying silicate blocks

gazosilikata is a popular building material, so each builder, choosing the material, should know - like putting gas silicate blocks.

material is a kind of cellular concrete, a lightweight, but at the same time ensures the reliability of the house.

However, it is important to produce masonry blocks, so you should know the stacking technology.

Application Method

silicate blocks can be laid in two ways: on the glue or cement-sand mortar.

course, cement and sand will cost several times cheaper than the adhesive, but the solution flow rate exceeds the adhesive consumption up to 6 times.

When laying on a cement-sand mortar thickness of the seams will be 1.5-2 cm, which has adverse effects: increased transmission of cold air formed mold, fungus, condensate.

need to prepare a solution sand and cement in a ratio of 3: 1.Water is necessary to add that amount to the solution was the consistency of a cream.Cement should be not lower than the mark M 500.

preferred material laid on a special adhesive composition having high adhesion.When using glue joints thickness 3.2 mm, almost no heat loss.

If construction is carried out in the winter, it is necessary to choose the glue to antimoroznymi components.

Prepare the glue must be so: the water is poured into a container, then poured dry mixture and stir everything.For mixing, you can use an electric drill with a special nozzle.


amount of water and glue depends on the adhesive, so immediately before use is necessary to get acquainted with the instructions for use.

recommended to prepare the glue in small portions, so as the composition dries quickly.

Working with glue, should comply with certain safety rules.Due to the fact that the adhesive contains cement, while the need to wear protective gloves and spectacles plastic.

also need to protect the respiratory system, which is put on a bandage or respirator.

How is the masonry?

to perform masonry gazosilikata need to prepare the following materials:

  • reinforcing rods with a diameter of 8 mm;
  • waterproofing material: roofing felt, bitumen, polyurethane, etc .;
  • sand and cement;
  • glue.

also need tools:

  • rubber mallet;
  • spatula, brush;
  • hacksaw;
  • template for customizing blocks;
  • cement mixer or a drill with paddle for mixing glue;
  • plane, float;
  • level;
  • brush with soft bristles.

When all the supplies and tools ready, you can proceed directly to the installation work.

Any structure begins with the foundation.When the device of the foundation certain conditions must be met for the house of silicate blocks.

First row

It is believed that for the silicate walls do not require a solid foundation, but this opinion is erroneous.

Due to the fact that gas silicate blocks are not resistant to bending, when driving a light foundation wall will crack.

Be sure to check the levelness of the foundation, differences should not be more than 1-1.5 cm. Properly constructed foundation will facilitate the subsequent work.

When the foundation is laid, it is important to create a rectangular base.

foundation level should be such that the first row of masonry does not touch the ground, because the blocks are very hygroscopic.

upper basement level runs above ground level or plinth is laid with ceramic bricks height of 0.5 m.

When the base is ready, marking is carried out for quality masonry.To do this, mark the four corners of the building.marking accuracy is checked several times by measuring the base diagonal.

units should uphold the grounds on the edge of 4.5-5 cm. This is to ensure that rainfall does not trickled down to the junction of the foundation, and the blind area.Between the corner blocks stretched marking strong thread.

For the convenience of performing marking bars can be used with nails, you need to go a little further into the ground.


Also, these bars will be required to align the corner pieces, as they allow to change the position of the blocks.

The next step is the foundation waterproofing.You can use penetrating waterproofing mastic, roofing and other materials.

applied waterproofing directly to the base in one or more layers.

example, if a roofing material, it is performed in several stacking layers 15-20 cm overlap, and each layer of sand-greased grout layer 10 mm.Laying

waterproofing must be done bearing in mind that the coatings should be greater than the width of the width of the wall.For waterproofing of walls is not required.

When the base is completely ready, you can proceed to the brickwork.Silicate blocks are the right shape, so their masonry is quite simple.

key point is the first number, which must be done properly, because it will serve as the basis for the entire wall.Mounting

first row always carried out on a cement slurry as the cement surface can align horizontally.First corner blocks are stacked.

Laying begins with the highest angle.Excess cement is removed trowel.Then fit the remaining blocks of markup.Details laying of the first row is shown in the video.

Installation starts from the inner wall side of the wall.Advance on the floor and walls need to partition.

Installation of the second row starts with promazyvaniya adhesive or a solution of the first row of blocks.Glue or solution is applied to the previous row and the surface layer on the vertical faces of not more than 0.5-0.7 mm.

If you use blocks with tongue-and-groove design, the adhesive does not need to be applied to the ends.Clay protruding from the joints, removed trowel.

Masonry series runs only 2 hours after placing the previous series.Using a mallet to align the blocks on the level.If there are any irregularities, it is possible to eliminate their plane.

Laying all series starting from the corners, but the direction of the corner blocks should be changed.


For example, if in one row unit has been placed in the long part of the left side, then the other series it is necessary to place a long part of the right side.

Thus, all subsequent rows are shifted relative to the previous not less than 8 cm. Interleaving ensures increased strength of the walls.Masonry made with ligation half the block.

Never stack gas silicate blocks in the rain due to the fact that the blocks have a honeycomb structure, which absorbs moisture.

If you need a smaller unit, it is possible to saw electric saw, which allows you to make a rounded, sloping curve or shape.When

Laid window and door openings in the top of the opening to be stacked first steel angles, the length of which must exceed the width of the opening is not less than 40 cm, and only then proceeds masonry blocks.

number of openings made in the form termopoyasov, it needs to use a U-shaped hollow blocks.To the outside wall into the unit is mounted foam board.

important stage of laying gas silicate blocks is reinforcement, which should be done after the fourth row.

reinforcement as follows: for the entire length of the series need proshtrobit electric wall chaser.Stroebe length should match the length of the reinforcing rod.

of Stroebe then you need to remove dust hairdryer.Then moisten with water and half-fill the adhesive composition, and then put the valve with a diameter of 8 mm.

To prevent corrosion of the reinforcement Stroebe need to fill, it uses a special solution.


If blocks thickness of more than 400 mm, the reinforcement is better to lay in two rows.Stroebe angles should be rounded.

reinforcement can be used for reinforcing the grid which is attached to dowels blocks.If all conditions are met, the walls will last a long time.

detailed process of how to put gas silicate blocks, you can see the video in the article.
