Building a house of gas silicate blocks

In the light of the constant appreciation of real estate and building materials, all those who wish to build their own house are forced to look for a cheap and high-quality alternative to brick. Build a house of gas silicate blocks. Today we will try to point out some of the nuances of erecting such houses, and also point out the frequent mistakes.

In particular, many beginning builders believe that under such a cottage you can lay a light foundation. Despite the low weight of this material, this should not be done. The fact is that the gas silicate block is a material that has an extremely low bending strength, and therefore the use of a light columnar foundation can lead to the appearance of cracks. And because the house of gas silicate blocks should not be built on a cheap basis.

The most universal and reliable option will be a foundation reinforced slab. It will be cheaper to use a simple ribbon foundation mounted on a cushion of large river sand. If the money is sufficient only for the columnar foundation, then it should be tied with a massive reinforced concrete belt. However, it's time to talk about how to build a house of gas silicate blocks. Please note that this material is highly hygroscopic, and therefore in no case should it be placed close to the ground.

To avoid unpleasant consequences, you can do two things:

• The easiest way is to fill the foundation itself so that its base is above the ground level.
• If it is initially flooded by the level of the earth, then you will have to lay out the basement of high-quality brick. The first row of blocks should be placed at a level not less than half a meter from the ground.

Waterproofing is first done. So, for this, a ruberoid is laid in two or three layers on the first row of the foundation. The first row is laid out using a conventional sand-cement mortar. It is very important at this moment not to make a mistake by making everything as neat as possible. Take into account that the blocks should be laid as evenly as possible, so that the whole house of gas silicate blocks in the subsequent did not sideways.

First put the corner blocks. Having installed a laser pointer or using the "grandfather" cord for this purpose, we put all the remaining blocks on it. All seams in the first row should be filled with special glue. To ensure that the blocks are as level as possible, they should be replaced with a rubber kiyanka.

If, due to your carelessness or poor quality of the material, irregularities appear on the top of the row, then use a special planer to eliminate them. We must do this, as we have already said that because of the fluctuations the blocks of the subsequent rows simply crack, making the house of gas silicate blocks not very attractive outwardly.

All subsequent series are laid out only for special glue. Note that for its ideal homogeneous consistency it is necessary to use a special nozzle on the drill, since it is virtually impossible to do this by hand. The glue must be applied with a special notched trowel. Before applying the adhesive, be sure to remove dirt from the blocks, sweeping them with a whisk. In any case, they build a house from gas-silicate blocks (reviews of such buildings speak for themselves) professionals.

We strongly advise against using sand-cement mortar. Firstly, the thickness of the seams in this case will exceed 10 mm. The thermal conductivity of the material rises sharply, and because of the absorption of moisture, it will quickly break down in the winter.
