DYWIDAG Post-Tensioning Systems are world renowned for reliability and performance, most suitable for all applications in post-tensioned construction. They embrace the whole spectrum from bridge construction, buildings , to civil applications, above and underground.
The first ever structure built with a prototype DYWIDAG Post-Tensioning System using Bars was the arch-bridge Alsleben (Germany) in 1927. From that time on DYWIDAG has continuously improved its systems to keep up with the growing demand of modern construction technology.
In addition to the traditional post-tensioning system using bars, that is mainly geared towards geotechnical applications, building rehabilitation and strengthening, DSI offers a complete product line in strand post-tensioning (bonded, unbonded and external) as well as stay-cables being able to fully serve the post-tensioning construction.
DYWIDAG Post-Tensioning Systems have always combined highest safety and reliability standards with most economical efficiency in their research and development.
Dependable corrosion protection methods of the DYWIDAG Post-Tensioning Systems contribute to the longevity of modern construction. High fatigue resistance is achieved with optimized material selection and cautious detailing of all the components especially in their system assembly.
We look back on many years of valuable experience in the field of post-tensioning which leads to our extremely versatile product range that offers economical solutions for practically any problem. This includes our highly developed, most sophisticated equipment which is easy to operate in all phases beginning with assembly, installation, stressing and finally grouting.
