After a period of engagement, the marriage followed: a joint venture with HOBAS was the result.

The management in Wietersdorf realised the potential of CC-GRP (centrifugally cast glass fibre reinforced plastics) Pipes and strove to establish a legally binding business with HOBAS. In 1984, this led to the joint venture with HOBAS. Today, the Wietersdorf holds 100% of the shares in HOBAS, managing this branch with a very successful team. The foundation for this positive development was laid way back in the 80s.
