DYWIDAG answers the growing need for global infrastructure investments

DYWIDAG was acquired by Triton Fund III in June 2011

From the steel in the first reinforced bridge in 1903 to railway sensors, DYWIDAG works with government authorities, asset owners, construction companies, and design offices to extend aging structures' lifespan and to build new infrastructure solutions to serve the growing demand for mobility and energy.  

DYWIDAG is working to answer the growing need for global infrastructure investments with products that create strong, safe and intelligent infrastructure. DYWIDAG is active across a dozen infrastructure sectors including bridges, slope stabilization, high rises, stadiums, nuclear, wind towers, and dams.

Its three main focuses:
Geotechnics: Rock and soil anchor systems for ground stabilization and infrastructure.
Post-Tensioning: Flexible load-bearing systems for bridges, wind towers and various other sectors in demanding environments.
Lifespan Management: Infrastructure Intelligence through maintenance, monitoring, and robotic inspections for every phase of life.

DYWIDAG’s systems are found in iconic projects such as The Golden Gate Bridge, Panama Canal, Kap Shui Mun Bridge, and Freedom Tower. With more than 1,500 employees and growing, the Group has 25 licensees in 50+ countries serving 10+ infrastructure sectors.

In 2010, DYWIDAG, formerly DSI, was taken over by its lenders after the company was unable to service the debt from a buyout in 2007.  During the sales process, Triton built a strong relationship with DYWIDAG's management. This, together with being a solution provider and securing guaranteed financing for the acquisition, was central to Triton acquiring DYWIDAG in June 2011.
