Company profile

WEMAS Absperrtechnik GmbH was established in 1971 and has grown into a full-range provider of certified passive mobile road safety equipment, including protective barriers, delineators, base plates, warning lamps and traffic cones. The company supplies both wholesalers and roadwork safety service providers serving the road safety, infrastructure and construction markets, predominantly in the DACH-region.

Investment rationale

The company operates in a growing market. Indeed, increasing traffic, growing investments in road infrastructure and safety concerns drive the need for safety products. WEMAS is well positioned to capture growth in the road safety market thanks to its fully integrated value chain and its focus on product innovation and value added services, including the highest number of certified road safety products in the industry and a wide range of customized products.

Growth strategy

Together with WEMAS’ ambitious and entrepreneurial management team, we will contribute to bringing the company to the next level and to helping realize its ambitions:

  • further growth of its passive mobile safety business in DACH and internationally
  • growth into adjacent road safety market segments, potentially through acquisitions

We are proud that we can use our network and our experience in building leading companies to co-shape the future of WEMAS.
