The Foundation „Flucht, Vertreibung, Versöhnung" (Flight, Expulsion, Reconciliation) has now found a home with a documentation center in the listed Deutschlandhaus with its spectacular extension in Berlin Kreuzberg. Built in 1926 in the style of the new objectivity, the building was completely renovated and reconstructed in 2013-2020 after an eventful history. The documentation center was opened at the end of June.
In the course of the structural condition analysis for the renovation, it was discovered that the supporting pillars in the basement were heavily soaked. This is not uncommon in Berlin basements; often the groundwater is only 1.5 meters deep. The nearby Landwehr Canal did the rest.
The piers were not only wet, they also had cavities. A suitable remediation concept was drawn up. The cavities were first filled with the PU foam resin WEBAC 150, then a horizontal barrier could be installed with WEBAC 1401, a WTA certified PUR resin. In the exterior masonry, a surface waterproofing with WEBAC 240 was carried out. All three products have been tried and tested for years and could once again prove their performance.
