Tunnels & Subways

Greater London Authority Building: Underground Tunnels
London, England

BACKGROUND
A state of the art office building with shops and restaurants, the Greater London Authority Building is also home to the Major’s office along the Thames River, next to the Tower of London.

The underground concrete tunnels and transformer room were constructed using conventional waterproofing systems but leaks occurred through the cold joints and cracks.

SOLUTION
Kryton’s “Krystol Concrete Waterproofing System” for repairing cracks, joints and holes in concrete (Specification No.1) was applied from the inside against the water pressure to eliminate water entry.

The drilled holes for the service pipes were filled with Krystol Baricote followed by a slurry application of Krystol T1 and T2 to stop all water from entering the service rooms.
