Tunnel Boring & Grouting

By Chris on 22-10-2020

The entrance of a tunnel being created by a tunnel boring machine can be as fascinating as the TBM itself.  Countless systems are being fed and networked to workers miles away.  That intricacy doesn’t just stop there. Even a seemingly simple task like routine maintenance can be a complex undertaking.  When poor ground conditions and or water is encountered, the engineering and coordination involved get taken to the next level.  Utilizing polyurethane injection, grouting contractor Sub-Technical, Inc. consistently provides engineered solutions in ground and water control for the tunneling industry.
