MasterRoc SLF 32

Foaming agent for soft grounds with low water inflows, readily biodegradable for Tunnel Boring Machines (TBM) applications

How does MasterRoc SLF 32 work?

MasterRoc SLF 32 is a foaming agent especially de-signed for soil conditioning in easy soft ground conditions, sandy soils with low water inflows. MasterRoc SLF 32 guarantees improved rheology of the excavated soil and facilitates extraction from outside the excavation chamber. MasterRoc SLF 32 is an eco-friendly foaming agent, being based on readily biodegradable raw materials.

What are the unique features of MasterRoc SLF 32?

MasterRoc SLF 32 is designed for sandy soils in any kind of environments, since it remains stable and homogeneous also when the temperature drops. MasterRoc SLF 32 can be used with the standard foam generators installed in all EPB machines. It can be injected at the cutterhead to the front, into the TBM working chamber and in the screw conveyor.

How does MasterRoc SLF 32 benefit customers?

Operational

• Optimized performance when mining in open and semi open TBM mode

• Facilitated muck extraction from tunnel and from the muck pit area

• Improved overall tunnel performance

• Reduced tunnel excavation time

• Reduced TBM maintenance costs

• Optimized muck logistics outside job site

Technical

• Creation of plastic deformation properties in the soil, which increases extraction

• Lower inner friction and lower abrasiveness of the soil at the cutterhead and shield
