In the Westphalian town of Versmold, the refurbishment of the urban sewage treatment plant was pending. Although the pools were in an astonishingly good overall condition after 40 years, all surfaces had to be refurbished. Damage to the joints and numerous cracks in the substance were particularly evident.

Short description
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.

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.
