The design of the sprayed concrete tunnel linings for Crossrail typically adopted the use of spray applied waterproofing membrane between two layers of permanent sprayed concrete. However structures on the west side of London were constructed through sandy clays, and therefore the risk of higher water ingress in the lower level tunnels drove the design towards conventional PVC sheet membranes. At Farringdon Station, BFK JV adopted the use of TamSeal 800 spray membranes for the higher level escalator and ventilation shafts as they were driven in the London Clay formation.
