Rhomberg Group: From Bregenz to Global Sustainability Preduce!
The Rhomberg Group has been fundamentally transformed since the 2000s and is a global rail technology and sustainability pioneer. Founded in 1886 in Bregenz, Austria, and now internationally in the construction, resource and rail technology sector, the company employs around 4,000 employees. The strategic realignment, which is particularly evident in the railway technology area, sets new standards in the industry.
An important step in development was the takeover of Bahnbau Wels GmbH in 2002 under the direction of Hubert Rhomberg. This increased the strategic importance of the railway technology area. In 2012, Rhomberg merged with the Swiss Sersa Group to the Rhomberg Sersa Rail Group (RSRG), which has now become one of the company's strongest pillars. In the 2024/25 financial year, the RSRG generated sales of 816 million euros, an increase of 56 million euros compared to the previous year.
Growth and innovation
In the 2022/23 financial year, over 50% of group sales came of approximately 1.4 billion euros, which means an increase of 7.5% compared to the previous year and is considered the highest sales in the company's history. In this context, the Rhomberg Group is active in important international infrastructure units, including the Koralmt tunnel, Semmering base tunnel and the Stuttgart 21 project, also in international space, especially in Canada, Germany and Switzerland, the company continuously expands its projects and market shares.
The Rhomberg Group increasingly relies on innovative and sustainable wood system solutions. This can be seen in leading projects such as the construction of a daycare center for Porsche and an office building in Ravensburg, as well as environmentally friendly residential complexes. A forward-looking project in Dornbirn is the stigling project, which includes 14 microapartments, equipped with photovoltaics and sustainable energy supply.
Sustainability in focus
Sustainability has established itself as a strategic leitmotif of the Rhomberg Group. The company focuses on wood and hybrid construction, recycling solutions and energy-efficient building concepts. The resource centers, such as the Rheintal Center Resource, set standards in the circular economy and process around 500,000 tons of excavation material annually, with over 50% of the building materials from recycling sources. In addition, climate -positive buildings are being built within the "Rhomberg Energy" program, which are equipped with modern technologies such as photovoltaics and heat pumps.
External awards such as the Trigos Award and Gold rating at Ecovadis confirm the company's efforts in the field of sustainability. The construction industry, which is responsible for a significant part of CO₂ emissions worldwide, is moving towards considerable reductions in greenhouse gas emissions. The Rhomberg Group plays an active role here by using resource -saving raw materials and integrating the last developments in the industry in order to continuously minimize their ecological footprint.
The future of the Rhomberg Group looks promising. The clear internationalization strategy and a large number of significant projects in countries such as Great Britain, Ireland, Australia and Canada show the potential for further expansion. The cost -effective use of raw materials and the focus on sustainable solutions position the company as a pioneer in an industry that urgently needs to change.
