Foundation contractor Kvaerner Cementation Foundations is stabilising a deteriorating 120 year old embankment on the main freight line from London to the Channel Tunnel using its new CemRailBeam system.
Working for programme management partnership Railtrack/ Laing at Lenham, between Maidstone and Ashford in Kent, the firm is due to complete the £1. 65M contract - from site investigation and design through to construction - in less than six months. With rapid growth in freight traffic in the area, much of it supplying the Channel Tunnel Rail Link projects, improving the stability of the 800m stretch of embankment either side of an underbridge was critical. Remedial work involves 1,200 vertical piles and 400 raking piles topped with a reinforced capping beam serving as a retaining wall at track level,10m above the base of the bridge. CemRailBeam is a precast capping beam system developed on Cementation's London Underground projects. The firm says that the system has allowed it to keep the contract on programme, despite one of the wettest springs on record.
