ABSTRACT:
A method of raising a building with respect to the ground; the method including the steps of: forming a mat having a number of through holes; inserting a foundation pile through each hole; fitting each foundation pile with a lifting device; exerting thrust on the foundation piles by means of the lifting devices to raise the building with respect to the ground; and fixing each foundation pile axially to the mat once the building is raised; the lifting devices are divided into three equivalent, symmetrical, independent work groups; and the lifting devices of one work group at a time are activated simultaneously, so that the building is raised isostatically, by simultaneously activating the lifting devices of one work group at a time, while the lifting devices of the other two work groups are left idle.
