features and Benefits

carefully designed to optimise muck flow properties for best
advance rate and excellent EPB pressure control.
Specific benefits Helps to create plastic flow conditions in the
absence of natural clay lubrication. Reduces cutterhead wear.
Reduces torque by improving muck lubrication within the cutterhead
and plenum. Eases feed to screw. Plasticises self levelling sludge.
Curbs water flow. Creates very stable, viscous foam.
