The substructure of a building transfers the load of the building to the ground and isolates it horizontally from the ground. This includes foundations and basement retaining walls.
It is differentiated from the superstructure which is the portion of a building which is constructed above the ground level.
It safeguards the building against the forces of wind, uplift, soil pressure etc. and it provides a level and firm surface for the construction of superstructure.
It also prevents unequal or differential settlement and ensures stability of the building against sliding, overturning, undermine due to flood water or burrowing animals.
