    MasterRoc® SLF 41 – Soil conditioning foam for Tunnel Boring Machines (TBM)​

    How does MasterRoc SLF 41 work?

    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, and can be used with the standard TBM dosing and foaming equipment.

    What are the unique features of MasterRoc SLF 41?

    • Improved soil behavior.
    • Easier ‘mucking’.
    • Reduced soil permeability.

    How does MasterRoc SLF 41 benefit customers?

    • Creation of plastic deformation properties in the soil, which provides an even and controlled support pressure and increased face stability.
    • Lower inner friction and lower abrasiveness of the soil at the cutterhead.
    • Reduced stickiness of certain soils, which would lead otherwise to blockage problems.
