BRAWOLINER® is a division of the Karl Otto Braun GmbH & Co. KG (KOB).
The parent company KOB was founded in 1903. Today KOB is the world’s leader in the manufacturing of special elastic fabrics used for medical and technical purposes. The company has a workforce of about 650 employees and production facilities of over 90,000 square meters.
Inspired by a case of damage in their own production line, KOB developed the first flexible textile seamless liner that enables the rehabilitation of pipes with bends up to 90° and can change in 2 different dimensional changes by using a special liner.
Specialising in small diameter pipes, BRAWOLINER® has become one of the leading system suppliers in the drain and sewer renovation industry. Beside the consumable liner and resin, the company also provides appropriate installation equipment and purpose-built, fully equipped vehicles and trailers.
Continuous research and innovation in the in-house research center enables us to consistently provide products that are used worldwide. A modern and vertically integrated production facility ensures complete control over all aspects of manufacturing. Well trained, efficient and qualified staff provides quality assurance of the highest standards.
Quality plays a significant role in the sewer rehabilitation. As the pipes in the ground are difficult to control, it is important to choose long-lasting and high-quality materials.
BRAWOLINER® follows the strict quality assurance standards of the medical industry. The KOB quality control department employs qualified staff and the necessary equipment to carry out all technical and chemical tests with ultimate professionalism. Constant quality assurance checks before, during and after production coupled with comprehensive documentation of the material properties guarantee consistently high product quality. For quality assurance purposes all products are clearly marked with batch numbers which allows all test results to be traced for many years after production.
As the first liner system BRAWOLINER® received the DIBt approval for the rehabilitation of small dimension sewerage systems in 2004. Today BRAWOLINER® is DIBt-approved for the renovation of underground pipes (permit number: Z-42.3-362) and of pipes laid inside buildings (permit number: DIBt Z-42.3-499).
