The Construction Ground Conference, accompanied by the Geotechnical Trade Exhibition, is one of the leading construction industry fairs and takes place every two years in the fall in Germany. This four-day event, organized by the German Geotechnical Society (DGGT), is dedicated specifically to the entire field of geotechnics. It provides a platform for exchanging the latest developments, research results, and established practices among experts and professionals. The fair serves not only as a showcase for innovative presentations but also as a forum for discussing current challenges and presenting innovative solutions. Participants can expect inspiring talks and stimulating discussions with leading industry figures. The program offers profound insights into topics such as soil mechanics, rock mechanics, and environmental geotechnics. A distinctive feature of the conference is its changing location with each edition, allowing participants to experience various aspects of geotechnics in different regional contexts. This enhances the understanding of regional geotechnical challenges and offers opportunities for professional networking and making valuable contacts. Highlights of the fair include special sessions on current topics, interactive workshops, and an extensive exhibition where companies and institutions present their latest products and services. The Construction Ground Conference is thus an indispensable event for all those active in or interested in the field of geotechnics. Already for the 39th time the Construction Ground Conference takes place on 4 days from Wed., 23.09.2026 to Sat., 26.09.2026 in Leipzig.
