It acts as a soil conditioner for various types of soil conditions ranging from wet to sandy clay type. It creates a necessary cohesion and plastic properties of excavated soil as well as a reduction of wear at cutterhead. It reduce the cutterhead torque and maintain constant earth pressure in working chamber during excavation process.
