Specialist contractor Concrete Repairs has carried out the UK’s largest ever application of ultra high modulus composite reinforcement as part of the strengthening programme for the cut and cover tunnels on London Underground’s District Line.
CRL used 1,300m of Sika’s CarboDur UHM system to strengthen over 90 cast iron beams on covered ways CW17 and CW20 either side of Embankment Station.
The covered ways carry the weight of Embankment Gardens situated above the District Line tracks. With a reinforced steel element deemed too thick to be a viable option, a system that was thin yet extremely tough was required. Sika’s composite plates were 7.3m long, 200mm wide and just 4.7mm thick.
