88 Wood Street Tunnel

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 3,500 litres/hour and the entire area was under 44 mm of water during the rainy season. All joints were treated with Xypex Patch’n Plug, Dry-Pac and FCM. Xypex Admix C-1000 NF was then used in the new concrete fill.
