• UV-Light liner

Braumann favours UV-Light liners – a state-of-the-art pipe line technology.

Braumann relies on UV-Light liners, an advanced pipe liner based on state of the art technology. Under factory conditions (consistent wall thickness) glass fibre  and polyester resin are pre-assembled in pipe liners that are storable for up to six months.


The pipe liner is pulled into the segment to be rehabilitated by winch. Then it is positioned with compressed air. The hardening is ensured by  a UV-Light chain pulled through the liner at a defined constant speed. The UV-Light liner can be applied to nearly every nominal width, even to egg-shaped and special profiles.


The essential advantages: a short construction time and minimal water control provisions. Plus: the possibility to control and reposition the liner before the hardening is initiated.

• Felt liner

In this case the liner is soaked with resins at the construction site and inserted into the rehabilitated pipe by an inversion drum.

Then the liner is inflated either with water air and pressed onto the pipeline wall till the hardening is completed. A form- and force-locking pipe-in-pipe system is built.

• Specific sewer rehabilitation

  • Short-Liner technology
  • Quicklock-socket rehabilitation
  • Robotic techniques


These ways of rehabilitation are recommended to remove damages in a single segment when punctual repairs are more economical. They are performed with Part-Liner, manchette or robotic techniques.
