TamSoil 265CF


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.
