Short description
The neo-baroque parish church of St. Martinus was built as a skeleton structure in a concrete / reinforced concrete construction. The exterior façade showed cracks in the wall shell, plaster and concrete. In addition, cavities, shearing off and spalling of concrete mouldings as well as iron corrosion were found. For a long-term restoration and preservation of the building, the concrete shell was partially replaced by a brick shell. In the course of the renovation, all corroded iron structures were also treated and corrosion protection was applied. Cracks and crevices were filled and decorative elements were preserved or restored. The plaster surfaces were reconstructed according to historical models. They were given a completely new coat of paint for a uniform overall appearance.

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.
