In the above example of the incorrect laying of the base of the four -story building, in addition to the crack on the facade, a massive formation of cracks was observed in the middle part of the building. The ZGO was a consequence of the fact that the construction site was not planned, an uncleaned building material was lying around the structure, the drain pipes were not installed and rainwater was not discharged from the foundation, but fell under its sole. The sole of the foundation in the middle part of the structure was laid below the bottom of the pit by only 0.5 m, and the soil was not protected from freezing. The water that penetrated the sole of the foundation due to the inevitable freezing of the soil caused a weakening of its resistance to the pressure of the building and was the reason for the formation of numerous cracks in this part.
