The depth of the foundation is a projected value that depends on the type of building or structure, the climatic zone, the soils on the site, and the level of occurrence of groundwater. This value is also affected by the construction of the building (with or without a basement), the principle of its use (with or without heating), storeys and mass.
If to speak in detail, this is the value on which it will be necessary to bury the foundation, in order that it provides a stable support for the structure. There are two types:
- deep laying;
- shallow or unshaded.
