Sievert

What Sievert does

Sievert SE is a Germany-based specialist for building materials and logistics solutions serving the construction industry, headquartered in Osnabrück with approximately 60 locations across Germany, Europe, and China and a workforce of more than 1,600 employees. The company operates a multi-brand product portfolio covering construction chemistry, insulation, facade systems, waterproofing, concrete repair, and garden/landscape construction under sub-brands quick-mix, akurit, tubag (with over 100 years of heritage), strasser, and hahne, manufactured across multiple German production sites including what the company describes as Europe's most modern dry mortar plant in Rosenau.

Revenue is generated through two streams: sale of premium building materials to construction professionals, landscapers, and dealers across German-speaking and broader European markets, and integrated logistics services under the Sievert Logistik brand. Logistics operations span a specialized fleet including silo vehicles, crane trucks, flatbed transport, and mobile forklift-equipped vehicles (Mitnahmestapler-Logistik) capable of on-site unloading, an uncommon capability that supports direct enterprise relationships as well as dealer distribution.

The company is legally structured as an Aktiengesellschaft (AG) registered at Amtsgericht Osnabrück (HRB 204128) but operates without public listing. Governance includes a Vorstand led by René Grupp (CEO) and Christian Schwarck alongside an Aufsichtsrat chaired by Prof. Dr. Norbert Winkeljohann with active Sievert family representation (Niklas Sievert, Gerrit Sievert, and Prof. Dr. Hans-Wolf Sievert as Honorary Chairman). Go-to-market combines direct field sales representatives (Gebietsleiter, Bauberater), dealer/merchant channels for building materials, application consulting services, and the Sievert Akademie education platform for trade professionals.
