The fact that the plate at this point there is a special hole for the pipe. And the builders of his post-heating close up. So I was so – from above a small layer of plaster, and under it – different stones, ie, construction debris, which the builders probably swept into a hole with a broom. These stones I pulled his hands up until they dragged (to break the neighbors I did not, but maybe this is worth it to do). Furthermore, primed poured all plitonitom (plaster). I remember in one room (for two holes for pipes) took something around 4 kg plitonita.
You can imagine what it was voluminous and deep holes. 3) nadpolnye seams. This is a place under the baseboards, where the floor plate closer to the wall. It all started with that in the winter, we noticed that out of the plinth is the frosty air. When near the study found that under the thin and often broken plaster has large cavity, which is quite possible to stick a pencil, and in doing so he did not make it to the wall.
Of these cavities and the incoming cold fresh air. At first, I even had the assumption that it is a hole right through, ie on the street. But from the street, I saw nothing. These cavities are often spread not only inwards, but also down. I think they were good . and because of their terminations as needed for insulation and soundproofing. Closed up all the foam and topped again plitonitom.
