Hydroment

Hydroment refers to special plasters for damp and salty masonry. A special chemical composition enables this plaster to be used primarily for the renovation and repair of damaged wall surfaces. Hydroment has been around since the 1940s. After temporarily disappearing from the market, this material was produced and used again from the 1970s.

The auxiliary construction material shown here should not be confused with a hydraulically controlled tool range of the same name .

history

Scientific advances in the first half of the 20th century prompted chemists, primarily on behalf of architects, builders and preservationists in cooperation with the building materials industry, to develop a special plastering mortar that can stop existing structural damage and at the same time provide new, full protection for the Represents building areas. The name hydroment of the building material thus created was derived from Hydro ~ (Greek for water) and cement . It consists, among other things, of sand , cement and special pore-forming admixtures such as expanded glass, which allow water vapor to easily pass through and thus prevent salt formation in the plaster. Hydroment is therefore also simply called dehumidifying plaster . It is applied one after the other in several layers up to 20 millimeters thick because of the better effect. Even after moisture penetrates later, it adheres firmly to the substrate.

This special plaster gradually lost its importance after the Second World War due to larger new buildings and newer materials . It was no longer offered in the following years. It was not until the 1970s that the production of this special plaster was resumed in the Federal Republic of Germany . It received the patented name Hydroment® Transputz , bears the CE mark and corresponds to the European standard DIN EN 998-1 for plaster mortar. According to a manufacturer, several million square meters of damp masonry, mostly in Germany, have already been successfully renovated. It has been continuously developed since then.

Formerly a hydroment plant in Berlin

In the 20th century, a production facility for Hydroment was built in the Berlin-Rummelsburg district of today's Lichtenberg district of Berlin . The designs for the production buildings come from the architect Georg Leowald . This factory called Hydromentwerk Rummelsburg was located in the immediate vicinity of the Klingenberg power station . She received the necessary raw materials on the waterway. After the end of the Second World War, production was temporarily stopped due to the destruction of the factory buildings. The Soviet city command used the remains of the building from 1947 to 1949 as a command building . The remaining war-related damage was repaired from 1949. In 1951 the new hydraulic plant started again with the production of binders . In 1964 it became part of the VEB Zementwerk Rüdersdorf and only continued grinding operations in Rummelsburg. 1972 presented the binder production entirely, but took in 1974 the production of cement again and stepped on the market as VEB concrete factory Rummelsburg on that specializes in the production of finished concrete slabs specialized for housing. After the end of the GDR , the plant was privatized and technically modernized and turned into a cement plant in Berlin .
