DSI and DYWIDAG Worldwide: A long Tradition of Innovation
The long tradition of the DYWIDAG license business began in 1950. It was based on the sale of know-how developed by DYWIDAG and was covered by a separate division within the company, the License Department. In order to meet foreign demand, DYWIDAG subsidiaries were founded in key markets.
As a consequence of the promising growth of this international business, DYWIDAG decided to co-ordinate these activities within a new, independent organization in 1979. The DSI Group was established in order to continue and further extend the successful worldwide marketing of DYWIDAG systems and technical know-how.
Nowadays, DSI is global market leader in the development, production and supply of Post-Tensioning and Geotechnical Systems as well as Concrete Accessories for the construction industry. Furthermore, DSI is a leading supplier of Ground Control Solutions for the mining and tunneling industries worldwide.
