Underground Solutions - Tottenham Court Road Station

Built over 100 years ago, the Tottenham Court Road underground station was not designed to cope with the level of passengers it experiences today. Areas of damp regulating layers were found within the tunnels prior to waterproofing. Instead of penetrating the concrete substrate for injection, MasterRoc TSL 865 was used. Once tacky, MasterSeal 345 was then sprayed over the full tunnel section, consequently reducing time spent on the activity and costs involved. A total of 124 tonnes of MasterSeal 345 and 2.5 tonnes of MasterRoc TSL 865 were used within the SCL tunnels at Crossrail’s Tottenham Court Road.
