A global leader in geotechnical and post-tensioning control systems

DYWIDAG was acquired by Triton Fund III in June 2011

DYWIDAG (formerly DYWIDAG-Systems International ("DSI") is a global market leader in geotechnical and post-tensioning control systems. Its products, which include bars, strands, are used in the construction and civil engineering industries.

DYWIDAG's history dates back to 1865. Today the company develops, produces and supplies systems in more than 90 countries and has 28 regional manufacturing sites. Services include the design, planning and installation of systems, as well as quality management and onsite supervision.

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. Triton had been following DYWIDAG since 2004 and had a good understanding of its potential. Triton took the view that the banks would not be long-term owners of DYWIDAG and approached them with a proposal in 2010.

The banks were keen to find a buyer with a record of being a solution provider to lenders and the ability to be a solid owner of DYWIDAG.

During the sales process, Triton built a strong relationship with DYWIDAG's management. This, together with securing guaranteed financing for the acquisition, was central to Triton acquiring DYWIDAG in June 2011.

DSI Underground, previously a business unit of DYWIDAG and a globally leading system supplier of innovative technologies for Underground Mining and Tunneling, has been carved out into a separate entity.
