Keller secures Polish contract

Keller has been appointed to construct access ramps and tunnel boring machine (TBM) launch and receiving shafts for Poland’s first TBM-driven tunnel.

Under the £30M deal, Keller will construct diaphragm walls to support the access ramps and chambers for the project to construct a 12m diameter, 1.1km long road tunnel below the Dead Vistula river in Gdansk. Keller will also use its jet grouting capabilities to install large diameter soilcrete columns for the scheme.

Work on the access ramps and chambers will start soon and is expected to be completed in spring next year.
