2. Historical development |
Many years, pipe rehabilitation was a completing division to the department of pipeline laying (division: PRT). By taking over the total shares of IMBEMA Group by Preussag Anlagenbau GmbH (today: PWR Wasser und Rohrtechnik GmbH), the divistion of pipe rehabilitation was further develop in 1989.
A contribution of this development was the takeover of "Klug" activities in the pipeline rehabilitation by IMBEMA in 1992. Simultaneously, 20% of the shares were sold to a private person. However, these were redeemed in 1994.
In 1992, the IMBEMA Rohrservice GmbH changed the name into Preussag Rohrsanierung GmbH.
In 1994, PWR got sole ownership again. PWR Wasser und Rohrtechnik GmbH implemented its activities in the pipe rehabilitation section into Preussag Rohrsanierung GmbH in 1997. Additionally, Preussag IMBEMA Klug GmbH and Imbema U-liners merged with PRS GmbH in the same year. It was the target to improve the market position of PRS by combining the activities in the pipe rehabilitation.
Berlin, Bad Friedrichshall and Spenge are further locations in Germany besides the official headquarters in Hanover.
The successful strategy of holding companies abroad has enabled the company to access to the local markets of their holdings during the past two years. These foreign holding companies contributed to the group´s turnover by approx. 50% in the financial year of 1998/1999.
