The Federal Association of Concrete Sewer Systems (FBS) is a new member of the Solid Unit innovation network. This move brings together a Germany-wide industry association for underground infrastructure construction with the nationwide network for sustainable and climate-neutral construction using mineral building materials.
“With the FBS, we are gaining a partner with technical expertise in the field of underground infrastructure,” emphasizes Thomas Zawalski, Managing Director of Solid Unit. "Robust, resilient drainage systems play a key role, especially in the context of climate adaptation. In view of the increasing number of heavy rainfall events, we need hydraulically and statically resilient solutions that will function for generations to come. They protect habitats, infrastructure, and the environment—and are therefore an indispensable part of public services.“
Dr. Markus Lanzerath, Managing Director of FBS, explains: ”Membership gives us the opportunity to raise even greater awareness of the prospects for underground infrastructure construction in terms of urban drainage and rainwater management. Mineral building materials stand for proven sustainability, durability, and high technical performance. The context of climate resilience in particular shows how important permanently efficient drainage and rainwater systems are for cities and municipalities. Together with Solid Unit, we want to further develop these strengths and make them more visible."
Since 1987, the FBS has represented almost all manufacturers of concrete pipes, manholes, and rainwater solutions and has been involved in all issues relating to quality and product standards in underground infrastructure construction. As a manufacturer-neutral competence center, the association supports public clients, planning offices, and construction companies in the use of concrete as a material. In view of growing climatic and ecological requirements, the member companies are working on CO₂-reduced manufacturing processes, innovative product solutions, and sustainable technologies. In addition, the association provides technical advice through its own field staff, is intensively involved in marketing concrete as a material and in training, and is active in international regulatory work. The FBS also carries out educational work—for example, on microplastic abrasion or possibilities for sustainable tendering practices—and promotes innovative topics such as artificial intelligence and building information modeling.
Solid Unit brings together players from the construction industry, the building materials industry, science, research, chambers, and start-ups. The network aims to promote innovation in solid construction and strengthen the transfer of knowledge between research, practice, and politics.
