DYWIDAG-Systems International (DSI) is a globally operating construction technology group headquartered in Munich, Germany. DSI produces and supplies high quality products for the mining and construction industry.
Starting in 1979, DSI’s origin lies in traditional construction systems. With the production of strata control products for the mining industry, DSI began to establish a new market segment six years ago. DSI now concentrates on two divisions.
The Construction division is focussed on DYWIDAG Post-Tensioning Systems, DYWIDAG Geotechnical Systems and on “Concrete Accessories”.
The Underground division is responsible for the development, production and supply of products and systems for mining and tunneling worldwide.
In cooperation with customers and business partners, DSI focuses on providing products and systems from a single source (one-stop-shop service). More than 2,000 highly motivated employees plan, develop, produce, refine, deliver and, if required, install DSI’s wide range of internationally standardized products and systems - always striving to exceed local, customer-specific demands and regional requirements.
DSI’s technical expertise and experience in planning and installation guarantee greatest flexibility and first grade security support for challenging engineering structures and mine roofs. DSI stands for total quality at all levels of activity.
DSI’s know-how is present on all continents and used in more than 95 countries worldwide by wholly owned subsidiaries, licensees, agents, and local production facilities. Thus, DSI provides short, customized supply channels - always in accordance with its slogan:
"Local Presence - Global Competence".
Research & Development
One of DSI’s primary goals is to contribute to a higher degree of quality and durability of structures.
DSI is committed to
- continually improving and adapting the existing DSI systems to the changing requirements of the world construction and mining markets
- research and development of new materials and components
- discovering advanced, efficient and economical systems and techniques.
DSI’s own laboratory closely cooperates with external research institutes, technical universities and numerous international technical committees and scientific organisations. DSI has a leading role in establishing quality levels and discovering new applications.
Quality Management

DSI is committed to exacting quality standards. In 1994, DSI received ISO 9001 certification for its own quality management system. The introduction, maintenance and updating of this system continually strengthens DSI’s fundamental corporate principle of meeting exceptional quality at all times.
Through its QM system, DSI ensures that all operations, including development, the sourcing of materials, the manufacturing of individual system components and the supply and implementation of DYWIDAG-Systems and Techniques are carried out in accordance with the principles contained in DSI’s QM Manual.
