Mega mole measuring 13 m in diameter for the excavation of this railway tunnel in Poland. It is the largest machine operated by SELI Overseas.

This project demonstrates how SELI Overseas knows how to meet a general contractor’s needs when they are looking for a company specialising in the operation of TBMs for critical works.

The large mole, measuring 13 m in diameter, is in fact used for the construction of a railway junction in the city of Lodz; the tunnel underpasses other railway and civil infrastructure with not many overburdens.

This work extends SELI Overseas’ expertise to mega moles, a sector that is also growing in terms of the number of applications around the world.
