Masonry of gazoblokov why attempts to make warmer end in failure

Aerated concrete blocks walls made noticeably warmer and thinner. Perfect steel and construction technology of ASG. Despite this, the problems associated with the human factor, more serious. Because of the freeze wall and even crack installation errors.

The main problem of the walls of aerated concrete

The most budget option - laying on a solution. But thick seams literally cut "warm" gas silicate grid of cold bridges. Skilled craftsmen are trying to make them as thin as possible. But strong divergence in geometry cheap blocks forces increase seam. No matter how hard you try, from cold bridges can not escape.

Masonry glue theory and practice diverged

In theory units intended for laying on adhesive mixture substantially differ in size (within each size). Tolerances - a few millimeters. They are easier to mount, and seam thickness becomes 2.3 mm. In practice, not all so rosy as we would like.

No matter how hard manufacturers, block sizes are far from ideal. To display a flat bed, the masons have to carefully shkurit surface. Masters who value their name, do so. Obtained smooth, thin seams (in theory). But often you can find a different picture.

Masons laying do hastily. The most popular method of filling of joints - abundantly cover up blemishes on the outside. As a result, we overpay for "flat blocks" to buy expensive glue mixture, and the seams are thick. The same with the heat engineering problems, just more expensive. Another characteristic of the jamb at a laying on glue - pustoshovka on vertical joints. By the way, is not the best way of organizing the house ventilation.

What pitfalls to expect from the adhesive foam

The problem is the same - a theory at odds with the practice. When builders follow the technology to build a smooth wall is obtained. And if not, the error is more serious price.

On the strength of the foam can not be compared with cement mortar. Serious error - to compensate for her uneven horizontal joints. Currently there are no loads, everything looks fine. The fun starts after loading the walls.

Thick foam joints are compressed under a load, and in the field inclines blocks begin to work on the cut. When the load reaches the limit, there are cracks. We wanted to make a perfect home, and got the freshly wreck ...

Apply modern technology can and should be. Only this should be done wisely. Expensive materials and budget masters - not a good combination!
