MasterRoc SLF 43 – Soil conditioning foam for Tunnel Boring Machines (TBM)
How does MasterRoc SLF 43 work?
MasterRoc SLF 43 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 43?
- Improved soil behavior.
- Easier ‘mucking’.
- Reduced soil permeability.
How does MasterRoc SLF 43 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.
