Abstract: The present invention provides a method and apparatus for making a foundation by creating a block constituted by the ground itself, the method being characterized in that at least one deep anchor point is established by using anchor means (1/3) buried underground by pile-driving, which means (3) extend in the anchoring position up to the surface of the ground in order to project beyond the surface; a slab (10) is placed on the surface, the slab including at least one opening for passing extensions from the anchor means; and traction is exerted on the slab in order to presetress the ground by using means situated above the slab (10) to put the anchor means under tension until an in-service force is obtained suitable for holding the structure to be built on the surface.
