All's well, that ends well: The BRAWOLINER's flexible range of pipes containing multiple bends makes it possible!

PKT - Rohr Frei has been working with BRAWO® SYSTEMS for over 20 years. Together with the company LTS Lilie from Gnoien, the sewer rehabilitation expert from Paderborn carries out projects in cooperation in the North of Germany

PKT - Rohr Frei from Paderborn carries out inspection and rehabilitation work with the help of market-leading application technology. The two companies PKT - Rohr Frei and BRAWO® SYSTEMS have been in a partnership over more than 20 years. As part of a current project in Stade, PKT Rohr Frei and LTS Lilie worked together to rehabilitate a 63m old pipe with a pipe diameter of DN  150 and several changes in direction from shaft to shaft. Due to the many bends, the two companies rely on the long-established, flexible epoxy resin liner from BRAWOLINER®.

The 63m long old pipe had already been prepared for rehabilitation the day before: Any obstacles and deposits were removed in advance and the residents were informed about the pending rehabilitation and possible short-term restrictions at an early stage. In addition to that various draining pumping systems were installed.
On the day of the rehabilitation, work began a little earlier than usual: Due to the large length, the liner was laid out on a large foil in front of the rehabilitation truck and then impregnated with epoxy resin. Meanwhile, the old pipe was cleaned once again before the actual rehabilitation.

After that  the liner could be inverted easily and cured with hot water. After the fast and problem-free rehabilitation, the inlets in the pipeline were milled again. The result was then checked and recorded via TV inspection. 

At the end of the day, site manager Karsten Wachs, LTS Lilie and engineer Sebastian Michel,PKT - Rohr Frei, look back on a trouble-free project. "We are enthusiastic about the fast and trouble-free rehabilitation with the BRAWOLINER®, which convinced us in this project, as usual, with its flexible range of pipes containing multiple bends . Together with my colleague Karsten Wachs from LTS Gnoien, I am already looking forward to many more projects with the BRAWOLINER®", summarizes Sebastian Michel, PKT - Rohr Frei  the rehabilitation project.
