Microtunnelling is one of the pipe jacking excavation methods. Our microtunnelling machines has slurry system in which the excavated material is transported from the face in a slurry. We manufacture various cutting heads which are available to suit a broad range of ground conditions. The pressure of the slurry is used to balance the ground face pressure. There is a lubrication system in our microtunnelling machines which injects a clay-based lubricant into the pipeline to be jacked freely through a fluid.
