This event has now ended

You can catch-up on details or any broadcast and downloads here.


Christian Gilbert of SYSTRA will introduce the ground freezing process and associated techniques, review the main design parameters as well as basic rules of thumb and risks.

A number of projects showing versatile use of the method will then be presented with a specific focus on  Metro Line 14 Clichy Saint-Ouen, Paris. With urban conditions and numerous complex constraints including railway proximity, this detailed case study will set out associated measured data and durations. 

Post-lecture drinks and food will be served at the ICE bar.

The drinks are sponsored by Systra and the food is sponsored by Tunnel Skills.
