Welcome to the Tunnelling Podcast

The Official Podcast of the British Tunnelling Society

Every day, beneath our feet, teams of men and women dedicate their lives to unearthing the underground space. As growing populations and urbanisation mount pressure on the already strained infrastructure of our cities, these men and women work round the clock to relieve the surface from our roads, rail, waterways and more. Tunnelling is still a young industry, with tunnellers carving our future landscape as they expand our use of underground space.

In this podcast, brought to you by the team behind the Engineering Matters podcast, and in partnership with the British Tunnelling Society, we go to the cutting edge of tunnelling, we see how digital technologies are making a young industry safer and helping bring projects to life that were previously thought impossible or unaffordable.

We explore advances in tunnelling technology, improvements in safety, we hear from leading experts, and industry disrupters. We share lessons from failures and celebrate successes. We tell the story of how far this industry has come and where these tunnellers are taking us next.

We do all this in The Tunnelling Podcast.
