The present disclosure discloses a system and a method for injecting a composition into soil. The composition is passed under pressure into a filler tube housed within an expandable element situated in a first hole. When the composition is pumped, therein the filler tube is raised and, the expandable element expands when the composition fills the expandable element, thereby solidifying the adjacent soil. Further, due to expansion, the structure above the ground is lifted. The rate of pumping the composition into the filler tube is determined by pressure of the composition, the type of soil, or by the chemical reaction detected by a first sensor and/or a second sensor present in a second or third hole. The material injected into the ground improves the soils beneath a structure, such as a house to create a resistance once the material permeates the soil and expands.

A method of treating particulate, in substance including selecting a load based on a planned in use loading of the particulate; applying the load to the particulate; injecting material below the load; and removing the load.

A method for lifting and repairing a foundation is disclosed. The method includes digging a well in at least one lateral surface of the foundation, installing a shear plate to the at least one lateral surface of the foundation inside the opening of the well, further digging the well to a maximum depth of 6 m, compacting a bottom surface of the well at the maximum depth of 6 m, forming a layer of gravel, compacting the layer of the gravel, placing a double column inside the well, pouring a plurality of gravel particles into the well, forming a cemented gravel layer by injecting cement slurry into the well to fill empty spaces among the plurality of gravel particles, installing a tensile system on top of the double column, forming at least a vacant space between the foundation and ground by lifting the foundation from the ground using the tensile system, and fixing the foundation by injecting cement slurry into the vacant space.

A cutting tool adapter for creating an underpinning structure and method of creating the underpinning structure are provided. In some examples, the cutting tool adapter may connect a cutting tool to a working machine arm to enable the cutting tool to cut and dislodge soil below an existing foundation or structure. As the soil is cut and dislodged, it is mechanically mixed with an additive, such as a cementitious material, via the cutting tool. The mixed soil and additive may then harden in the area below the existing structure or foundation to create an underpinning structure to provide additional support for the existing structure or foundation.

The invention relates to a soil working device for creating a substantially vertically running hole in the ground, which hole is provided with a slurry, said soil working device having a base body, a connection apparatus which is arranged on an upper end region of the base body, and a soil removal apparatus and/or a soil displacement apparatus, which is arranged on a lower end region of the base body. According to the invention is intended that, at a lower region of the base body, a first pressure measuring apparatus for measuring a first ambient pressure is arranged, and that at an upper region of the base body, which is vertically spaced apart from the lower region, a second pressure measuring apparatus for measuring a second ambient pressure is arranged. The invention also comprises a method for creating a substantially vertical hole in the ground by means of such a soil working device.
