One of M.J. Eriksson's areas of competence is the Micro Tunneling process of piping for drainage and supply lines.
Micro Tunneling means that we drill and establishes a tunnel underground, and thus replaces an open excavation of large areas. Tunneling is unique due to it tunneling applications of through densely populated settlements and under buildings. This may also be applicable for the situations where you want to avoid closing a train or road stretch.
M.J. Eriksson's tunneling machine makes it possible to establish Concrete or HOBAS pipes with diameter from 600 mm up to 4000 mm, to a distance of 1,000 meters from the starting pit for receiving pit, construction of new pits if there is a need for longer passages.
