If you have a house from slag blocks, the upper corner has moved in it, a through crack has formed, moreover, not one, what to do? In your situation, the most correct one will now find this a specialist who will come to you and will assess the situation on the spot. After all, now the most important thing is to find the reason why you have cracks in your house. Well, when the reason wakes up, known, then you will make a decision.
In any case, the reasons can be diverse and to the banal simple. We include the absence of a blind area against the wall of the building and the flow of water from the roof in the same place, which ultimately leads to soil soil and the subsidiary of the foundation.
One of the reasons may also be the absence of a monolithic belt in the upper part of the wall. The monolithic belt distributes more evenly the load from the ceiling and the structure of the coating (roof) on the walls and further on the foundation. If your crack is opened from the bottom up, then this is a clear indicator of the absence of a monolithic belt, and the load from the roof, especially in winter, when snow lies on the roof, is transmitted to the wall of the building and tears it away from the main box of the building. Then in this situation you will have to make a roof for a new one, only in order to carry out a strapping of walls in the upper part.
Therefore, we repeat once again, find a specialist of the designer, hang him into a place to identify the causes of cracks in the house, and listen to his recommendations on how to do it. After all, to demolish the wall and the foundation or make out the roof, it all pulls financial investments, or maybe it will be cheaper for you to put screeds now and start building a new house.
