The ISTT is delighted to announce that Mark André Haebler (AATT, Austria) has been confirmed as the new Chair of the Society. This confirmation took place at the ISTT International Council Meeting, held on 26 October 2025 at the Vancouver Convention Centre, where representatives from 18 Affiliated Societies around the world gathered to shape the future of trenchless technology.
We are also pleased to share that Carlos Andres Munera (LAMSTT, Latin America) has become the new Vice Chair of ISTT.
We extend our sincere gratitude to Keh-Jian (Albert) Shou (CTSTT, Taiwan) for his outstanding leadership and dedicated service as outgoing Chair. Under his leadership, ISTT enhanced international collaboration and continued to promote sustainable trenchless technology worldwide.
The Society further wishes to express its heartfelt appreciation to Jari Kaukonen (FiSTT, Finland), who has now completed his term on the ISTT Board of Directors. As Past Chair, Jari made remarkable contributions to the ISTT community, notably leading the successful International No-Dig 2022 in Helsinki during the challenging COVID-19 period. His steady leadership and commitment helped ensure the event’s success in uncertain times.
The meeting also included the election of new members to the ISTT Board of Directors. We are pleased to welcome:
- Wing Chang (CHKSTT, Hong Kong) – re-elected for a second term
- Börje Persson (MATT, Malaysia) – elected for his first term
Congratulations to everyone! We look forward to ongoing growth, innovation, and collaboration within the global trenchless technology community.
