BRAWOLINER® and Spray-Liner® are divisions of the Karl Otto Braun GmbH & Co. KG (KOB). The parent company KOB was founded in 1903 with seat in Wolfstein / Germany. Today KOB is the world's leader in the manufacturing of special elastic fabrics used for medical and technical purposes.
Inspired by a case of damage in the own production line, KOB developed the first flexible textile liner that enables the rehabilitation of wastewater pipes with bends up to 90° and dimensional changes (BRAWOLINER®).
The KOB GROUP took over the Spray-Liner GmbH in January 2017. Spray-Liner GmbH is a specialist for sealing damaged wastewater pipes within buildings (so-called in-house rehabilitation). At the core is an epoxy resin, which is sprayed onto the faulty sections of pipe from the inside.
The combination of BRAWOLINER® and Spray-Liner® is the ideal solution for renovation of damaged buried wastewater pipes and pipes within buildings with a diameter between DN 50 and DN 250.
During the exhibition showcase the Spray-Liner method will be introduced and samples of renovated pipes in combination with BRAWOLINER® and Spray-Liner® will be presented.
