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.
