A method for hardening soft soils by injecting mortar, the method comprising the following steps: a) performing one or a plurality of soil perforations; b) introducing a central tube in each perforation for injecting mortar, a semi-permeable casing for storing the injected material, and one or a plurality of side sleeve tubes adjacent to the semi-permeable casing and located at the outer portion thereof; c) injecting the mortar by means of the central tube for forming a core for reducing deformities; and d) injecting a predetermined volume of mortar by means of the side tubes, in order to form lateral sheets protruding from the core. The cores along with the lateral mortar sheets are useful for transmitting to the subsoil the loads received from superstructures, the cores modifying the deformability of the soil mass so that reducing the effects of the differential deformities which may affect the structure, and the lateral sheets turning the cores into more efficient elements.
