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.
