Abstract
Cellular foil (3) is unfolded between the surface of earth base course (1) and the first floor layer (5) during building the subsoil, which cellular foil (3) is poured over with fill (4) from loose material at least up to filling the compartments. A bedding (2) from loose material, optimally from sand, is created under the cellular foil (3). Geotextile (6) may be incorporated to the area under the cellular foil (3). Bedding (2) of lower grain size than that of the fill (4) is preferably used, wherein the fill (4) has optimal grain size of 8 to 63 mm. Compaction is done by at least eight travels of roller of 10 to 11 tons weight, also including vibrations when the height of fills is exceeding 25 cm above the cellular foil (3).

Method of making a flat foundation for a floor without substantial excavation in which the floor subsoil for buildings, particularly halls and assembly shops, is built on made-up earth base course (1), when the floor is shallow founded in that way that the first floor layer (5) from concrete-based material is laid on modified background, characterized by that at least one layer of cellular foil (3) in unfolded state is laid down onto the background before laying down the first floor layer (5), than this cellular foil (3) is overfilled with fill (4) from loose material reaching at least up to the height of the cellular foil (3), thus filling the cavities in its chambers, the fill (4) is compacted and the first floor layer (5) is laid down only now onto this compacted fill (4).
