Research & Development - Patents

In 1979, DYWIDAG-Systems International (DSI) was founded to distribute products for construction and geotechnical applications based on DYWIDAG patents. DSI engineers soon began to further develop this “inherited” know-how with their innovative ideas, thereby constantly improving the original products and developing new ones. 

DSI permanently monitors, amends, reviews, tests, and adapts its wide product range to meet new regulations and official approval requirements. DSI attaches great importance to R&D in order to continuously provide high quality products to its customers. About 100 employees around the world are focused on R&D and engineering.

Research & Development

The systematic research in materials, structural engineering and construction methods is coordinated in the regional headquarters, thereby pooling and combining the global know-how from all sectors of the group for the benefit of all customers.

Consistent with DSI’s strategy “Local Presence – Global Competence”, competence centers are located throughout the world.

Patents

The consistent protection of developments through patents and utility models has been and remains a priority for DSI.

At the beginning of 2016, DSI held 56 basic patents in the Post-Tensioning & Geotechnics sector.
