The base on which a house or other structure is built or installed, connecting the structure and transferring its load to the ground. Questions using this tag should include additional tags to identify the type or material of the foundation.
Foundations serve as the base upon which a house, structure, patio, deck, or other structure is built, and connect the structure to the ground. The foundation transfers all the load of the structure to the ground, so must be able to withstand the large forces involved.
Houses tend to have concrete foundations, whereas patios or walkways may have layered foundations of stone and sand. In houses with basements, the foundation may refer only to the floor or may refer to the floor and walls of the basement.
