The integrity and proper functionality of the foundation can be destroyed for reasons of a natural or construction nature. These reasons are absolutely independent of the quality of the construction and construction teams. Since the construction of the foundation and the house as a whole is usually carried out in the summer, summer overalls will be needed for those involved in the construction..
Among the first, the incorrectly selected type of foundation can be noted. It may not be enough to withstand the material, or it may not be suitable for the type of building. Sometimes they forget to check the reinforcement, waterproofing. Also, the quality of the foundation can suffer from excessive savings in materials, violation of the sequence of construction stages, technology, organization of the foundation, the presence of miscalculations in the design process. It is necessary to take into account the features of the site and the geology.
Natural reasons can rightfully be called: freezing, swampy soils, heterogeneous dynamic soil, intensity and volume of groundwater, changes in level, direction and movement. All these points must be taken into account in the design process and compilation of calculations of a sufficient type of foundation, preparation and strengthening. They can change when influenced by natural disasters..
Deformations can occur due to expansion, completion of the second floor, redevelopment, the use of heavy materials in the decoration of facades, replacement of the roof and other important changes that are carried out without strengthening the existing foundation.
