Foam additive TamSoil 265CF

soil conditioning

TamSoil 265CF is a soil conditioning foam with water sucking properties specifically developed to be used on a tunnel boring machine (TBM). It acts as a soil conditioner for various types of soil conditions, especially saturated coarse soils. TamSoil 265CF gives the excavated soil the necessary plastic properties and reduces soil stickiness at the cutterhead, working chamber and screw conveyor. TamSoil 265CF also creates a homogeneous and compressible spoil in order to reduce the cutterhead torque and secure a constant earth pressure in the working chamber during the excavating process. Key Benefits Reduce wear of discs and other parts of the mucking system Efficient mixing with the excavated soil, reducing cutter head torque Significantly decreases soil permeability Improves spoil rheology Environmentally safe and non-toxic Typical Applications EPB tunnel boring machines
