Abstract: The present invention relates to a method and a system for making prefabricated foundations ready to be driven into the ground, these foundations have the fundamental characteristic of increasing the size of the reacting pressure “bulb” in the ground compared to the currently known fixed foundations, in fact, compared to a traditional foundation fixed in the ground, in which the area of the foundation section is constant, the present invention allows to increase this area by increasing it during the insertion of the foundation itself.

Abstract: The invention has for object a system and a method for the realization of floating platforms formed by the aggregation of floating forms in reinforced concrete, the union set of the modules is made integral forming a single plate inserting and pulling special steel cables that cross the entire platform in sheaths arranged in the walls of the modules themselves, the pulled cables, locked in this position, compress the plate to increase resistance, the present method and system are also characterized by the fact that the quota of the platform does not vary with the tides and the loads to which it is subjected.
