Visqueen Building Products is proud to be a part of the ventilation and access shafts project at Crossrail Contract 360 Eleanor Street and Mile End Shafts, on the route between Whitechapel and Liverpool Street stations.
Crossrail awarded the project to Costain Skanska JV in 2012. Worked started towards the end of that year and has seen two shafts built to around 30 metres below ground. The shafts will house ventilation and emergency exit facilities between Stratford and Whitechapel stations.
At Mile End, work included the relocation of a coach park and all-weather football pitch plus ensuring continued access to the Mile End Park Leisure Centre for the local community throughout the project.
The ventilation shafts along the Crossrail route have been designed to ensure optimal air movement within the tunnels. As Crossrail trains will be air-conditioned, they will release warm air. The shafts will help extract this warm air out of the tunnels.
SIG Construction Accessories in Thurrock, stockists of Visqueen Building Products tanking membranes, supplied the project with Visqueen TorchOn Tanking Membrane and the Visqueen TreadGUARD1500 protection board.
Two layers of the TorchOn Tanking Membrane have already been installed; this has then been protected by TreadGUARD 1500 to ensure the membrane is protected during construction of the RC Slab.
Additionally, CSJV will be using a circular GX Hydrocarbon Damp Proof Course preformed unit around the tops of the Shaft walls, effectively linking the vertical polymeric Membrane in the shaft to the tanking membrane under the slab.
