A TBM creates a smooth, round excavation profile compared to the non-uniform profiles created by drill & blast and roadheader operations. This smooth profile reduces the amount of maintenance needed on the finished tunnel, as well as the amount of required ground support during tunnel excavation. If the tunnel is segmentally lined, a minimal amount of maintenance is required.
