The joints of the pre-cast unit, and the basement core on level 4 of this service tunnel suffered water ingress.

During the repair of the tunnel, water ingress measured 3500 litres/hour and the entire area was under 44 millimetres of water during the rainy season. All joints were treated with Xypex Patch'n Plug, Xypex Dry-Pac and Xypex FCM. Xypex Admix C-1000 NF was then used in the new concrete fill.
