Straightforward Refurbishment of the Selzthaltunnel with MasterSeal 345

The Selzthaltunnel is a double-tube motorway tunnel on the A9 Pyhrnautobahn near Selzthal in Austria. After 40 years of operation it was in need of refurbishment. For this project the owner of Selzthaltunnel relied on MasterSeal 345: double bonding properties facilitate a reduction of the thickness of the secondary lining to retain the required minimum clearance, making replacements unnecessary.
