Koster Bauchemie AG

Andrew & Jamie were recently invited to attend the Koster Bauchemie AG factory in Aurich, Germany.

Koster Bauchemie AG is a manufacturer of waterproofing systems and one of the companies RTC use for their specialist waterproofing applications.

Along with some other leading specialist contractors across the UK, the visit consisted of an introduction to Koster Bauchemie AG and their 40-year history of being at the forefront of technology and innovation. There were a number of in-depth presentations on the products and their uses, technical information about the products, and case studies of where their products have been used on prestigious contracts around the world.

The visit also consisted of hands-on, in-depth training on the products’ applications, product knowledge and the application process. Here at RTC, we believe that we are always learning and developing. Product knowledge, as well as building relationships with key partners, is a vital part of staying at the forefront of our industry.

The visit was completed with a tour of Bremen, which is a fantastic city, steeped in tradition and history.

All in all, it was a great experience, and we would like to say a big thank you to both Delta Membrane Systems and Koster Bauchemie AG for a fantastic visit.
