Impact Mole

This allows the laying of pipelines of 90-180 mm in diameters which are realized through dry-drilling by means of compressed air thrust systems, from an entry pit to an exit pit. The pipe is laid directly during drilling, by connecting it to the mole extremity using appropriate fittings of small dimensions.

As it is not possible to effectuate significant corrections to the drilling direction, this should be appropriately orientated at the right depth from the onset.

Its utilization is optimal for limited laying lengths and in urban environments due to the reduced dimensions of the machinery,  while it is conditioned by the presence of boulders of significant dimensions compared to those of the machinery.
