Greater London Authority Building

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.

Large holes were drilled through the concrete to allow room for service pipes and they were prone to leakage due to the high water pressures of the Thames River.

Solution

Kryton’s Krystol Concrete Waterproofing System for repairing cracks, joints and holes in concrete 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 Waterproofing System to stop all water from entering the service rooms.
