In 1984 the well-known paver finisher manufacturer Hoes GmbH, bases in Wardenburg, was acquired. Later the Demag Schrader company was also acquired and integrated into the Mannesmann Demag Concern. The marketing and distribution of all Demag machines was handled by Demag Construction Düsseldorf.
After Mannesmann was taken over by Vodafone and the asset stripping of the construction equipment group Mannesmann-Demag, the roller / paver divisions were sold to Dynapac. The products, including rollers, are today still produced in plants in Lingen, Wardenburg and Sweden.
