ITTC 2025 would be held from April 23 to April 25, 2025 in Suzhou International Expo Center, which is guided by China Society for Trenchless Technology (CSTT), International Society for Trenchless Technology (ISTT), Japan Society for Trenchless Technology (JSTT), Malaysia Society for Trenchless and Tunneling Technology (MSTTT), Turkish Society for Infrastructure and Trenchless Technologies (TSITT), China Hong kong Society of Trenchless Technology (CHKSTT), and supported by German Confederation of Small business and Skilled Crafts (ZDH China), China Association for Engineering Construction Standardization, Pipeline Inspection and Repair Professional Committee of China Municipal Engineering Association, Zhengzhou University, China University of Geosciences (Beijing) - College of Engineering and Technology, China University of Geosciences (Wuhan) - College of Engineering, Chengdu University of Technology, Tongji University College of Civil Engineering, Jilin University College of Construction Engineering, China Petroleum Pipeline Scientific Research Institute, Beijing University of Technology, Harbin Institute of Technology, etc.



On April 26, 2024, the three-day 27th ITTC came to a successful conclusion. The exhibition covered an exhibition area of 20000 square meters, and the organizing committee selected over 120 companies from the industry to showcase their latest products and technologies on site. Among them, 24 companies participated in the exhibition for the first time, accounting for 20% of the total exhibitors. 95% of the participating companies brought dozens of physical products for exhibition, and all the raw spaces were specially decorated, and all the products on site were sold out. 3718 professional visitors from 19 countries and regions, including 32 provinces and autonomous regions across China, registered to visit the exhibition. The three-day exhibition received 8080 visits, and 172 registered to attend the seminar.

ITTC is showcasing the vibrant vitality and potential of China's Trenchless Industry with a scale that exceeds expectations and a wealth of cutting-edge technologies. With the end of the epidemic, the Chinese economy is taking the lead in global recovery. The feedback from exhibitors and visitors reflects the growing demand for trenchless technology in China's national economic development. The active participation of foreign experts and reporters demonstrates the attention of international peers towards the continuous expansion of China's trenchless market. Driven by favorable domestic policies, the sustainable improvement of sewage treatment plants nationwide is being carried out in parallel with the improvement of pipeline quality and efficiency, as well as pipeline repair work. Faced with the huge market of urban pipeline maintenance and repair, municipal enterprises or emerging enterprises have joined the trenchless industry, and the number of exhibitors in pipeline inspection and repair has surged.


ITTC is an important platform for getting acquainted with new customers, meeting old friends, delivering information on industry trends, and sharing future technologies. We are full of confidence in the future, and the global economy is gradually recovering. In 2025, we will continue to arrange exhibition halls according to the classification of trenchless technology, providing visitors with a better exhibition experience. In order to achieve this goal, we will continue to work hard.


Here, we sincerely invite relevant companies and professionals in the trenchless industry to participate in conferences and exhibitions. We look forward to discussing the prospects of the trenchless industry and discussing business with you in Suzhou!
