ABSTRACT:
A method of constructing a foundation 10 for a building includes forming in the ground a grid 12 of intersecting foundation trenches 14, 16. The grid 12 is made up of two sets of substantially parallel trenches, the trenches of the sets being respectively designated 14 and 16, each trench 14, 16 of each set intersecting at least one trench of the other set. Settable material, eg concrete, is continuously cast within the trenches 14, 16 to obtain an integral grid 18 of two sets of intersecting foundation between 20 (in the trenches 16) and 22 (in the trenches (14). The spacing A between adjacent pairs of trenches 14 or 16 and between adjacent pairs of parallel beams 20 or 22 of the grid 18 is 1,5 meters. A covering of concrete is continuously cast over the beams 20 and 22 and integral therewith, to obtain a slab 24 (FIG. 3) covering the beams and the ground 26 between the beams 20 and 22, the slabs having a flat upper surface 28 (FIG. 3).
