Since its foundation in 2001, Rädlinger primus line GmbH is headquartered in Cham in the Upper Palatinate. In the recently renovated office building, the growing Primus Line team has enough space for further development in an attractive atmosphere. Here, both technical development of the technology for trenchless rehabilitation and project-related engineering take place.


The plant of Primus Line in Weiding nearby is full of surprises inside. The approximately 20 metre high building accommodates three vertical production lines including the unique circular looms for the production of the liner. Up to 4,500 metres of liner in one piece can come from one line.
