Technologies - TBM

Highly efficient products optimize TBM performance

The MasterRoc product range offers a single source of solutions for shielded TBM(tunnel boring machine) excavation in soft ground and hard rock, increasing TBM advance rate and improving operational efficiency:

• MasterRoc SLF range of ground conditioning foams give maximum efficiency for every soil type encountered during EPB tunneling.
• MasterRoc SLP range of polymers enhances the MasterRoc foams in difficult conditions.
• MasterRoc ACP range of anti-clay agents reduces clogging and adhesion on metal surfaces on soft and hard rock TBMs.
• MasterRoc TSG range of tail sealants is well proven and cost-effective.
• MasterRoc BSG range of main bearing sealing greases give effective main bearing protection with outstanding properties resistant to wash-off.
• MasterRoc EPB high quality EP2 greases.
• MasterRoc ABR unique anti-wear and dust suppression technology is designed for hard rock TBMs operating in abrasive ground.
