Sisgeo's Borehole Extensometers: comprehensive solutions for axial monitoring

(Chapters below) Understanding ground deformation is essential for the safety and performance of tunnels, earthworks, dams, slopes, and deep foundations. In this comprehensive webinar, geotechnical engineer Julien Prouvot presents a complete overview of Sisgeo borehole extensometers, explaining how these instruments allow engineers to monitor axial displacement with accuracy and confidence even in the most challenging geological conditions. You will learn how extensometers work, how their components interact, and how to choose the right system - single-point, multi-point (MPBX), chain extensometers, mobile probe systems, or in-place sensors - based on project requirements, accuracy needs, and ground conditions. The session highlights the importance of correct anchoring, grout selection, and installation techniques, as well as the benefits of pairing extensometers with digital dataloggers, wireless nodes, and advanced remote monitoring platforms. The webinar includes real examples from tunnels in rock and soil, earth embankments, landslides, retaining structures, excavation shafts, and underground works. Through practical insights and field cases, you will understand how extensometers support design verification, performance monitoring, and early-warning applications. This video is ideal for geotechnical engineers, instrumentation specialists, contractors, designers, monitoring service providers, and infrastructure owners interested in improving data quality, reducing uncertainty, and adopting reliable, standards-compliant monitoring solutions.
