88 Wood Street, London

Famous for its ventilation tunnels, 88 Wood Street is in the heart of the City of London. Beneath the building is a tunnel constructed of pre-cast concrete that holds plant etc.

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.

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.
