DSI and DYWIDAG Worldwide: A long Tradition of Innovation

 

The long tradition of the DYWIDAG licence business began in 1950. This was based on the sale of know-how developed by DYWIDAG and was covered within the company by a separate division, the Licence Department. To meet foreign demand DYWIDAG subsidiaries were founded in key markets.

 

Following the promising growth of this international business DYWIDAG decided in 1979 to co-ordinate these activities within a new, independent organization. The DSI Group was established in order to continue and further extend the successful worldwide marketing of DYWIDAG systems and technical know-how.
