Abstract: A system for injecting expanding resins into soils to be consolidated, includes a pump apparatus which is operationally associated, at a delivery port, with a tubular element which can be inserted into a respective hole defined in the soil to be consolidated and is adapted to send to the tubular element a mixture at a preset supply pressure. The tubular element has a number of holes, at least two of the holes including respective calibrated holes.

Abstract: An elongated connecting element for anchoring members, which is provided with a first anchoring end portion designed to be inserted into an anchoring region and a second end portion which defines a head, which lies opposite the first anchoring end portion and is designed to interact with an element to be anchored. The elongated connecting element includes an external tubular element which accommodates an internal elongated body, the external tubular element defining, at the head, at least one feeding port for a synthetic anchoring mix and, at the first anchoring end portion, at least one exit opening for the synthetic anchoring mix. The synthetic anchoring mix is configured to set, penetrating at least partially into the anchoring region and creating a stable connection between the anchoring region and the elongated connecting element and between the respective portions of the external tubular element and of the internal elongated body.

Abstract: A method for improving the mechanical and hydraulic characteristics of soils, including a step of providing tension members or nails which have an anchoring portion anchored in the soil to be improved and a second end portion fixed substantially at the surface of the soil to be improved; and a step of injecting cement mixtures or synthetic mixtures into the volume of soil to be improved below the surface. The mixture injection step is performed after providing the tension members or nails.

Abstract: A method for optimizing processes for increasing the load-bearing capacity of foundation grounds includes the following steps: detecting at least one part of a built structure and/or of ground; identifying at least one region to be treated of the foundation ground; and injecting, at least one injection point located substantially within the at least one region to be treated, a cement and/or synthetic mixture. The method further includes at least one second step of detecting at least one part of the built structure and/or of the ground that lies above the injected foundation ground. The method further includes a step of interrupting the injection step, and measuring at least one physical parameter that is susceptible of varying as a consequence of the injection step.

Abstract: A method for improving the mechanical and hydraulic characteristics of foundation grounds of existing built structures, includes the following steps: a first step of two-dimensional or three-dimensional sensing of at least one portion of the built structure; a step of identifying at least one region of intervention in the foundation ground beneath the at least one portion sensed in the first sensing step; and a step of injecting, through holes provided at least at a part of the intervention region, a cement or synthetic mix. The method further includes second steps of two-dimensional or three-dimensional sensing, mutually spaced in time, of the at least one portion during the injection step; and a step of interrupting the injection step on the basis of the information gathered during second steps of two-dimensional or three-dimensional sensing of the at least one portion.

Abstract: A method for water-proofing underground structures (10) comprising: a step of injecting an expanding compound adjacent to the surface (10b) directed toward the outside of an underground structure (10) to be waterproofed in order to form at least two confinement portions (2); a step of injecting a diffusing compound (4) intended to harden adjacent to the surface (10a) directed toward the outside of the underground structure (10) and at a completion region (3) that is delimited by said at least two confinement portions (2).

Abstract: A method for waterproofing below-grade structures includes at least one step of injecting at least one compound adjacent to the surface that is directed toward the outside of a region of soil arranged adjacent to a below-grade structure to be waterproofed. The method further includes at least one step of measuring the electrical resistivity of the at least one region of soil subjected to the injection step. The at least one measurement step is adapted to detect the portions of the region of soil that are affected by the injection of the at least one compound.
