TORKRET, repair of the U5/U8 connecting tunnel, Berlin, 2016/17

Repair of U5 / U8 connecting tunnel, Littenstraße Berlin (2016/17) TORKRET fully renovated the so-called Waisentunnel, a single-track metro tunnel in Berlin underneath the river Spree, in order to maintain the structure’s load-bearing capacity, serviceability and train safety for the long term. The restoration works covered several vaulted ceilings (856 m²), tunnel walls (427 m²) and a total of 21 cross girders. The work was carried out on interior scaffolding, with limited working height, using the back step method under full closure of the metro line.
