The Fenger Group was founded by Torsten Fenger in 1988. Since then, the construction company has grown steadily and is now active in various areas related to concrete and building materials. The Fenger Group produces and controls the divisions at 7 locations. The group of companies consists of the areas of prefabricated basements, concrete and gravel, logistics and real estate. The Fenger Group started with the logistics of building materials in 1988 with one vehicle. Fenger Beton und Kies was soon added, where up to 300 different types of concrete are produced for customers in mixing plants.

The plants required the expansion of the logistics division, since the company's own building materials had to go to the customers and the raw materials for production also had to go to the mixing plants. After continuous development, Fenger Fertigkeller was founded in 2004, thus expanding the spectrum of building materials manufacturers and logistics service providers to include building contractors.
