TBM Tunneling in Cohesive Soils


Sticky clays are one of the most challenging ground types for soft ground TBMs to excavate in. This webinar will highlight MAPEI’s chemical solutions to use when particularly cohesive soils are encountered in both EPB-TBM and slurry TBM. Laboratory tests and project references will be shown.

Learning Objectives:
Attendees will learn:

  • How to choose chemical products to manage clogging issues during TBM excavation;
  • How to apply anti-clay foaming agents and polymers;
  • And why the application of the right products and methods can improve the TBM production.

This is a presentation with Tunnel Business Magazine.
