1. A modular foundation having a shape of a slab, the modular foundation including:
a plurality of prefabricated concrete modules defining:
an upper layer of modules including at least one internal passage opening onto at least its upper and lower faces, a height of the upper layer being less than a width of the upper layer and a length of the upper layer,
at least one lower layer of modules on which the upper layer at least partially rests, a shape of at least one of the modules of the at least one lower layer being different from a shape of at least one of the modules of the upper layer, including at least one internal passage opening onto at least one of its sides and onto at least its upper face, a height of the at least one lower layer being less than a width of the at least one lower layer and a length of the at least one lower layer,
the internal passage of said at least one lower layer communicating at a level of an interface between the upper and lower layers with the internal passage of the upper layer in such a manner as to form at least one global internal passage in the modular foundation, said internal passage opening onto at least one side and onto at least an upper face of the modular foundation,
at least some of the modules including a vertical cavity on at least two opposite sides adapted to form with an opposite vertical cavity of an adjacent module a vertical internal passage of greater section, or the modules of the lower layer or layers including at least one horizontal cavity on at least two opposite sides adapted to form with an opposite horizontal cavity of an adjacent module a horizontal internal passage of greater section.
