The invention relates to a method for repairing damage (2) to constructions in particular to pipelines (1) or ducts, wherein the damage (2) is temporarily at least mostly sealed to the environment by means of a repair device (3) and a mineral-based injected agent (17) introduced to the damaged point (2) and a corresponding two-component injected agent (17). The injected agent (17) is made from a cement component (Z) and an accelerator (B) containing a cement hardening accelerator (E), mixed in an injecting buffer (3) directly before application, for example, in a static mixer (16) and then applied to the damaged point (2). A long processing time for the individual components (Z, B) is thus achieved and a rapid bonding of the prepared injected agent (17), such that a rapid work progress can be achieved. The cement components (Z) containing cement and water and optionally bentonite and a solvent. The accelerator components (B) are made from the hardening accelerator (E), water and a latent hydraulic material, such as, for example, fly-ash or optionally bentonite. An approximately equivalent volume and similar flow properties can thus be achieved for both components (Z, B) with a high solids fraction and good reactivity. |
