TamSoil 267CF is a polymerised soil conditioning system specifically developed to be used on a tunnel boring machine (TBM). It acts as a soil conditioner for various types of soil conditions, especially below ground water table. TamSoil 267CF gives the excavated soil the necessary plastic properties and reduces wear at the cutterhead. TamSoil 267CF 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.
