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.

TBM Products

MasterRoc ABR 5

MasterRoc ABR 5 is a liquid anti-abrasion agent designed to reduce the abrasive wear to the cutting tools, substantially reduce dust formation during excavation and cutterhead clogging in hard rock and earth pressure balance tunnel boring machines.

MasterRoc ABR 7

MasterRoc ABR 7 liquid foaming agent is specifically designed to reduce abrasive wear to the cutting tools in tunnel boring machines (TBM), and to substantially reduce dust formation during excavation.

MasterRoc ACP 127

MasterRoc ACP 127 is the second generation of anti-clay additives for tunnel boring machines. It is a liquid polymer, especially designed for clayey soils with high clogging and adhesion potential.

MasterRoc ACP 130

MasterRoc ACP 130 is specially designed to reduce the clogging and adhesion effects of clayey soils and clays that have a very high plasticity index.

MasterRoc ACP 143

MasterRoc ACP 143 creates a stable foam and can be used with the standard foam generators installed on EPB machines. It can be injected at the cutter-head, into the working chamber and screw conveyor.

MasterRoc BSG 1

MasterRoc BSG 1 is an extruder sealant for tunnel boring machines. It effectively protects the main bearing and prevents water, soil, and dust from entering into the main bearing sealing.

MasterRoc BSG 11

MasterRoc BSG 11 is an extruder grease for tunnel boring machines (TBM). It effectively protects the main bearing and prevents soil, water or dust ingress into the main bearing sealing.

MasterRoc EPB 11

MasterRoc EPB 11 grease is a multi-purpose EP2-grade grease designed for main bearing lubrication, as a screw conveyor drive assembly grease and as a rotary swivel grease.

MasterRoc SLF 30

MasterRoc SLF 30 is a foaming agent specially designed for soil conditioning in shielded tunnel boring machines. It is suited to soft ground tunneling and can be used with standard TBM dosing and foaming equipment.

MasterRoc SLF 41

MasterRoc SLF 41 is a polymer reinforced foaming agent specially designed for soil conditioning in shielded tunnel boring machines. It is suited to soft ground tunneling and silt to sand soils which may contain a high amount of water.

MasterRoc SLF 47

MasterRoc SLF 47 is a highly eco-compatible polymer-reinforced foaming agent especially designed for soil conditioning in tunnel boring machines.

MasterRoc SLP 1

MasterRoc SLP 1 is a lubricating polymer in liquid form, that is used to enhance the performance of MasterRoc SLP foam products under difficult ground conditions, e.g. ground containing fine sand, silt, or clay with high water content.

MasterRoc SLP 2

MasterRoc SLP 2 liquid polymer is used to enhance the performance of the MasterRoc foaming products in difficult ground conditions. MasterRoc SLP 2 liquid polymer is used in coarse soil with low fine content or saturated soil with high water pressure.

MasterRoc TSG 16

MasterRoc TSG 16 is a tail sealant for shielded tunnel boring machines with a brush seal system. It effectively seals together with wire brushes the gap between the shield tail and the concrete segments to prevent the ingress of water, grout and soil.

MasterRoc TSG 6

MasterRoc TSG 6 is designed for use in conditions where the ambient temperature will usually remain above 10°C. It is formulated to resist high water and ground pressures, and has excellent pumping properties and adhesion to all surfaces.

MasterRoc TSG 7

MasterRoc TSG 7 tail-shield sealant is used for shielded tunnel boring machines (TBMs). MasterRoc TSG 7 sealant effectively seals the gap between the shield and concrete segments to prevent the ingress of soil, water or grout.
