A global leader in strata, geotechnical and post-tensioning control systems


DSI was acquired by Triton Fund III in June 2011
Dywidag-Systems International ("DSI") is a global market leader in strata, geotechnical and post-tensioning control systems. Its products, which include bars, strands, wires and meshes, are used in the construction, mining, tunnelling and civil engineering industries.

DSI'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. DSI employs 2,138 staff.

In 2010, 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 DSI since 2004 and had a good understanding of its potential. Triton took the view that the banks would not be long-term owners of DSI 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 DSI.

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

Key events since Triton's investment

  • Prior to its investment DSI was distracted by over-leverage and an uncertain ownership. Triton has given support and certainty and the company has de-leveraged. This combined with a strengthening of the management team and board has allowed the business to refocus on industrial decisions.
  • DSI has acquired majority stakes in the UK mining contractor Drill Trek Systems, and in the Russian mining consumables distributor DSI Techno. It has also acquired 2 mining consumable businesses in the US.
