Many regions in Germany show a rising groundwater level. Hence, the load case of buildings concerned changes from non-pressing to pressing water. Residential buildings not designed for the load case of pressing water have to be refitted. Conventional sealing methods are often associated with high complexity and high costs as well as the loss of living space. Furthermore, in many cases, they do not consider the additional static load of pressing water at all. This paper presents a newly developed, subsequently applied sealing against pressing water. It is made of textile-reinforced concrete. Using this composite material, it is possible to produce a sealing system with a wall thickness of about 30 to 35 mm (1.18 to 1.38 in.). During the production of an exhibit wall, it became apparent that the spraying technique is an adequate and practicable method to produce a subsequent sealing of textile reinforced concrete. Initial observations of the wall subjected to hydrostatic pressure reveal the application potential of this construction.
