The building, which is about 40 metres high, was built in the 1970s. 202 balconies, distributed over the two building fronts, were to be renovated and repaired. The concrete surfaces of the balconies required renovation. For the typical concrete fascias, repair was out of the question. In order to save costs, the entire refurbishment was carried out with the aid of rope-operated suspended scaffolding. This was lowered from the roof which made it possible to renovate 13 balconies in one step.

Short description
The concrete surfaces of the balcony parapets were repaired and a surface protection was applied. This has a hardening effect, is alkali-resistant, open to water vapour diffusion and water-repellent. The prepared substrate was then painted with a mineral paint in accordance with a specified colour concept. In order to implement this individual concept, a special colour shade was produced that exactly met the customer's requirements. The balcony fronts were replaced and covered with a metal sheet.

The structure showed cracks in some places, for which there were different causes. Improved statics and higher load capacity were achieved by stiffening the structures, frictional connection of the disturbed foundation and decoupling the components gate, passage hall and gate houses components. Particularly on the western side, intense blackening of the rock surface had built up, which was strongly interlocked with the ground. The deposits were composed of a mixture of soot and plaster. The cleaning process carried out in 1990 with the help of water could only result in a superficial cleaning. In 2002, the newly developed method of particle beam cleaning and cleaning by laser 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.
