Enhancing Safety at the Auerberg Tunnel with Advanced Geotechnical Monitoring
At maxGEO, we are proud to support the Auerberg Tunnel project, a critical infrastructure development aimed at improving traffic flow and safety on the B23 near Garmisch-Partenkirchen. This tunnel will help reduce congestion and enhance mobility while navigating complex geotechnical conditions.
For HTB Bau, we have installed two three-point rod extensometers at depths of 40 m and 50 m, equipped with vibrating wire displacement transducers. These highly sensitive geotechnical instruments provide real-time data on ground movement and deformation, helping to mitigate risks at the retaining structure near the tunnel portal.
What are rod extensometers?
Rod extensometers are essential for measuring subsurface displacement in soil and rock. By tracking movements at different depths, they provide critical insights into ground stability, allowing engineers to detect potential deformations early and take preventive measures. The vibrating wire sensors ensure precise long-term monitoring, even in challenging conditions.
With the Kramer Tunnel facing geotechnical challenges and project delays, our monitoring solutions play a key role in ensuring safety and stability during and after construction. We are proud to contribute to this important project with advanced geotechnical instrumentation!

Recently, maxGEO successfully deployed an advanced geohazard monitoring system for Austrian Railways (ÖBB) in Styria, near Retznei, addressing a critical slope failure that posed a significant risk to railway operations. The installation of Senceive’s InfraGuard system, equipped with high-precision tilt sensors and draw-wire sensors, now enables continuous, real-time monitoring of slope movements and crack openings, providing early warning of potential failures.
The region of southern Styria is characterized by complex geological formations, including sedimentary rocks, marls, and clay-rich layers prone to slope instability. Weathering, seasonal groundwater fluctuations, and ongoing natural erosion contribute to an increased risk of landslides. In railway corridors, where cuttings and embankments intersect these vulnerable geological layers, proactive geohazard monitoring becomes essential.
Rail infrastructure is highly sensitive to even minor ground movements, which can compromise track stability and safety. Traditional inspection methods, while valuable, cannot provide the real-time data needed to detect rapid changes. By implementing wireless sensor technology, ÖBB now benefits from:
✅ 24/7 remote monitoring of slope movement and crack development
✅ Automated alerts for early warning and risk mitigation
✅ Data-driven decision-making for maintenance and safety strategies
As geotechnical risks continue to challenge critical infrastructure, maxGEO remains at the forefront of innovation, delivering solutions that protect railways and enhance operational resilience using Senceive’s advanced monitoring technology.
