In late October 2025, the our after-sales service team successfully conducted a three-day on-site technical training session in Hanoi, Vietnam, focusing on the operation and application of the Ultrasonic Drilling Hole Monitor (UDM)—our advanced system for assessing borehole and diaphragm wall quality.
This comprehensive training program covered both software and field operation, providing hands-on experience and data analysis skills to ensure our client’s team can confidently and independently operate the equipment for their ongoing construction quality assurance projects.
The training was divided into three progressive modules, designed to take the participants from theoretical understanding to real-world mastery:
Each module was carefully structured to address different aspects of the ultrasonic testing process—from equipment setup and calibration to data interpretation and reporting.
The first day was dedicated to software operation and system familiarization. Our technical specialist introduced the fundamental principles of ultrasonic detection for drilled shafts and diaphragm walls, followed by a detailed demonstration of the TENSENSE Ultrasonic Drilling Hole Monitor software interface.
Participants learned :
During this session, our engineer also guided the team through troubleshooting procedures and signal interpretation basics, ensuring they could quickly diagnose and resolve common field challenges. The interactive Q&A session helped clarify several technical details, especially concerning signal waveform characteristics and calibration procedures.
The first day concluded with participants successfully completing simulated data collection exercises indoors, building a solid foundation for the upcoming field training.
The second day marked the highlight of the program—on-site field operation at a construction project in Hanoi. The field session aimed to give participants direct experience with the Ultrasonic Drilling Hole Monitor’s full operation workflow, from setup to data recording.
The TENSENSE service team demonstrated:
To ensure a fair and practical evaluation, the client arranged a performance comparison test between the TENSENSE UDHM and Japan’s Koden system, one of the internationally recognized brands in ultrasonic drilling hole testing.
Despite the challenging working conditions at the site, the TENSENSE system demonstrated stable signal performance, rapid data acquisition speed, and clear visualization of borehole profiles. The client’s technical team was impressed by the instrument’s operational efficiency and user-friendly interface, especially during the real-time comparison stage.
At the end of the field day, both teams discussed the testing results in detail. The client acknowledged the accuracy and reliability of the TENSENSE data, which aligned closely with reference readings while offering a more streamlined workflow.
The third day returned to the classroom for data interpretation and reporting. The focus was on helping participants master the Ultrasonic Data Analysis Software, which converts field-acquired signals into meaningful engineering information.
Participants were given real datasets from the previous day’s field tests to analyze independently, guided by TENSENSE engineers. This approach allowed them to experience the full cycle—from data collection to analysis—enhancing their understanding of how ultrasonic reflection signals correlate with actual borehole conditions.
By the end of the session, each participant successfully generated a complete quality evaluation report, marking the successful conclusion of the training program.
Throughout the three-day program, the client team demonstrated strong engagement and enthusiasm. Their cooperation and technical curiosity greatly contributed to the smooth progress and positive outcomes of the training.
In their closing remarks, the client’s project manager expressed appreciation for the professional support and in-depth technical sharing provided by the TENSENSE Geotech team. They highlighted that the training not only improved their operators’ skills but also increased confidence in adopting TENSENSE’s ultrasonic technology for upcoming quality control projects.
This successful training in Vietnam is part of TENSENSE Geotech’s continuous commitment to providing comprehensive after-sales service and on-site technical support to international clients. As infrastructure development continues to expand across Southeast Asia, ensuring the integrity of pile foundations and diaphragm walls has become increasingly critical.
Our Ultrasonic Drilling Hole Monitor provides contractors and testing companies with:
By offering both equipment and hands-on training, TENSENSE ensures that our customers not only acquire advanced testing instruments but also gain the necessary expertise to use them effectively.
Following this successful training, TENSENSE Geotech plans to expand localized service and support networks in Southeast Asia, providing faster response and more direct assistance to regional clients.
We would like to extend our sincere gratitude to our Vietnamese customer for their hospitality, cooperation, and dedication during the entire training process. Their professionalism and openness to learning played a key role in achieving this fruitful outcome.
As we continue to innovate and enhance our deep foundation testing solutions, TENSENSE Geotech remains dedicated to delivering accurate, reliable, and professional testing systems that contribute to safer and higher-quality infrastructure projects worldwide.
The Ultrasonic Drilling Hole Monitor (UDM) is an advanced non-destructive testing (NDT) system developed by TENSENSE Geotech for evaluating the integrity and geometry of boreholes and diaphragm walls. By utilizing high-frequency ultrasonic reflection principles, the system can accurately reconstruct the borehole’s cross-sectional profile, detect collapses or sedimentation, and assess the verticality and continuity of drilled shafts.
