Under the motto "New Challenges, Underground Solutions", this year's congress focused on how underground infrastructure can contribute to addressing future social, technical and environmental challenges. Sustainable construction methods, innovative materials and modern technologies played a particularly important role. The demands placed on underground structures continue to grow: they must not only meet the highest technical standards but also remain safe, reliable and resource-efficient over the long term. For SEALABLE, the event provided a valuable opportunity to explore these developments and gain new perspectives for its own areas of expertise. In tunnel construction, high-quality and durable sealing solutions are an essential component of reliable infrastructure. Exchanging ideas on new technical approaches and industry-specific requirements provides important impulses for continuously improving existing solutions and developing innovative concepts to meet future challenges.
