Jet grouting is a ground improvement technique used for a wide range of underground structures, including tunnelling projects. We encourage you to advance your tunnelling knowledge with our CPD-certified Online Tunnel Engineering course, designed for engineers and professionals worldwide. 👉 https://tunnel.engineering/TE-training-academy/course/c8fdcce2-1ca8-49e3-a122-9238e57dc318/tunnel-engineering-course/ We also deliver CITB Temporary Works Coordinator (TWC), Temporary Works Supervisor (TWS),

The Sun shines because of quantum tunnelling ☀️ Jim Al-Khalili illustrates this phenomenon, where a particle passes through an energy barrier like it's "tunnelling" through a wall. Watch the full talk: youtube.com/watch?v=k-0pky806Fo | Royal Institution of Great Britain

A tunnelling project in Austria. Did you know the NATM tunnelling method is originated in Austria? The NATM (New Austrian Tunneling Method) originated in Austria in the 1950s. It was developed by Austrian engineer Ladislaus von Rabcewicz, together with other engineers like Leopold Müller and Franz Pacher. The method revolutionised tunnel construction by emphasising flexibility, adapting to ground conditions, and using systematic observational techniques during excavation. NATM has since been wid
