b/s/t.
The pioneer. Family business in the fourth generation.

Today, the family business b/s/t is managed today by the brothers Sebastian and Johannes Koch, who are following in the footsteps of their father Hans-Jürgen Koch (†2021) and continuing the family business in the fourth generation: "Our company history is characterized by innovative new developments. Our great-grandfather originally developed cars. Our grandfather revolutionized flat roof waterproofing. Our father shaped textile architecture alongside the further development of b/s/t with his sister company Koch Membranen GmbH. The two brothers say: "We sons are looking forward to continuing the family history and leading the company into the digital age - without neglecting the values of our ancestors." With a great deal of passion for the family business, they are now leading the traditional company into a promising future in plastics and metal processing with state-of-the-art technology and contemporary thinking.

b/s/t products have always been simple, technically good, unpretentious and practical. The products fulfill a highly functional task by providing solutions for critical details and interfaces in the waterproofing of flat roofs. Although the accessories only make up a small part of the construction performance, the consequences for the entire building can be enormous if something goes wrong. "That's why functional quality is always our top priority. This high standard of performance can only be guaranteed through the use of highly efficient machinery in combination with the careful craftsmanship of our products," explains Michael Zimmermann, who is responsible for machinery and production processes, among other things, in the technical team. The innovative technology enables consistent product processing with the highest precision and under controlled conditions; for product solutions that are characterized by a long lifetime in all components.

The success of b/s/t is based on the simplicity, flexibility and individualization of its products. A high level of depth of production and experienced, well-trained employees ensure first-class product quality at any time. Despite increasing internationalization, b/s/t relies on local production in Rimsting am Chiemsee. A strong network of long-standing suppliers and partnership-based cooperation create security for customers. These advantages of regionality, together with personal contacts in sales and technology, ensure the desired quality and service standards as well as absolute delivery reliability. Meanwhile this is the case in over twenty countries. Sabedin Vokrri, responsible for international sales, reports: "We offer our customers the full range of accessories for their flat roof. Our products are customized. Our clientele now extends far beyond Europe. We speak our customers' language and know their country-specific needs - often for decades."

If necessary and technically possible, b/s/t products are delivered within 24 hours according to the specific requirements of the respective project. In this way, the processes on the construction site can be supported in the best possible way - even when time is of the essence. Maximilian Schöll from the technical team explains: "A large proportion of the products, especially the plastic parts, are manufactured in-house. If necessary, our specialists can adapt the products by hand to the customer's wishes." Marcus Kusian, also from the technical team, adds: "In some cases, production is even changed to meet specific customer requirements. We have a very diverse and experienced team to be able to implement individual requirements." And Markus Mayer, authorized signatory and sales manager, defines the task of his sales team as follows: "Service means being able to offer customers what they need. Not necessarily always what they want. Finding out the difference is our job and an important step in guaranteeing quality."

Most b/s/t products are developed out of the application. They are designed to be simple and functional. Each mounting part is provided with a connection collar. This enables quick and safe installation. Matthias Dircks, responsible for quality assurance in the technical team, explains: "The technical team provides technical support on application guidelines and standards for all planning tasks in the flat roof sector. We prepare calculations for the drainage of flat roofs or the positional stability of roof waterproofing. The correct dimensioning of drainage is very important. Incorrect results can be dangerous in practice."
