Sometimes it is necessary to consolidate very old structures, consolidating not only the foundations, but also the structure, but without making it too rigid. In these instances, injections of lime whitewash are applied, which is slightly unusual in most cases.
A significant number or underpinning are made using micropiles for foundations where existing structures need to be supported due to building refurbishments with increased load needed on the foundations, to avoid or control settlements, as a preventive measure to give extra capacity before executing nearby infrastructure or deep excavations for underground parking lots construction.
