The Brandenburg Gate in Berlin was built between 1788 and 1791. As well as being the city’s most important landmark, it is also a national symbol that is associated with many important events that shaped Berlin, Germany, Europe and the world at large in the 20th century. The building in the early classicist style marked the border between East and West Berlin. Until reunification, it was an emblem of the Cold War. Since 1990, the Brandenburg Gate has symbolised the reunification of Germany and Europe.

Short description
For various reasons, the structure was beginning to crack in some places. The structural stability and load-bearing capacity were improved by bracing the structures, creating a force-fit bond at the damaged foundations and decoupling the gate, passage hall and gatehouses. On the western side in particular, the stone surface had darkened considerably over time, with the subsoil sticking to it firmly. The deposits consisted of a mixture of soot and plaster. Cleaning was carried out in 1990 using water, but this only had a superficial effect. In 2002, the newly developed process for particle jet cleaning and laser cleaning made it possible to remove soot and plaster without destroying the original surface.

On the façade surfaces of Kaispeicher A, there was a lot of efflorescence and lime aging, both signs of penetrating moisture. The damage patterns indicated a lack of frost resistance as well as no protection against driving rain. The listed façade required extensive frost and moisture protection, but was not allowed to undergo any visual changes.

The pool is permanently exposed to positive and negative water pollution. It was therefore important that an expansion zone remains in the middle of the joint seal, which allows the structure to work and provides an optimal surface. The joints should still be reliably sealed. Both the crack repair and the concrete repair were carried out in accordance with the classic procedure in accordance with the repair guidelines, in which cracks are closed by injecting epoxy or polyurethane resin using a drill packer. The concrete surfaces in particular had to be protected against chemical attack, especially against the high ammonium pollution from the connected meat industry.
