With HAW Linings GmbH in Bornum (Harz) the GBT group has brought the inventor of the industrial rubber lining into its ranks. Patented in 1920, it was this technology, which today's chemical industry in Germany must be thankful for in enabling it to achieve its leading position. 

In its highly specialised area of technology, HAW Linings GmbH has made its mark in many ways. Including, for example, the largest autoclaves for vulcanisation and the largest centre with own rail connection for rubberised tank wagons in Europe.
