MasterRoc SLF 30

Soil conditioning foam for Tunnel Boring Machines (TBM)

How does MasterRoc SLF 30 work?

MasterRoc SLF 30 is a foaming agent especially designed for soil conditioning in shielded tunnel boring machines.

What is MasterRoc SLF 30 used for?

• Soft ground tunneling

What are the benefits of MasterRoc SLF 30?

• Improved soil behavior

• Easier ‘mucking’

• Reduced permeability and increased sealing at the face

• Creation of plastic deformation properties in the soil, providing even and controlled support pressure and increased face stability

• Lower inner friction and lower abrasiveness of the soil at the cutterhead through to the screw conveyor and conveyor, reducing power consumption, enabling soil extraction and conveyance, and reducing wear costs

• Reduced stickiness in certain soils, which would lead to blockage problems.
