Underpinning can be done in one of two ways: one, improve the foundation system by enlarging the existing foundations or adding new foundations, and two, to improve the properties of the soil below the foundations without touching the building at all.
The foundations of houses, as a rule, are made of stone or concrete (less often – of wood). They are prefabricated, monolithic and precast monolithic. On abyssal soils, the building structure is laid below the depth of freezing of the soil.
On non-porous, slightly shallow foundations are used (foundations with a laying depth above the freezing level of the soil are used only for light buildings. Depending on the design, the foundations are: pile, pile-grillage, columnar, tape and slab. In the construction of individual residential buildings, the last three are most often used.

Why is Underpinning Necessary?
There is a variety of reasons why underpinning might need to be carried out. These are usually related to subsidence issues. Some examples of why underpinning might be necessary are:
- A change in soil conditions under the foundation.
- Soil characteristics were not properly taken into account during the design phase.
- The original foundation is no longer suitable/strong enough.
- The construction/repair/excavation of neighboring structures endangers the current foundations.
- Additional floors are to be constructed underground
