The Northern Line Extension is currently under construction from Kennington to Battersea, terminating at the redeveloped Battersea Power Station. The extension will form a continuation of the Charing Cross branch of the line. Tempo-PCE won the segment repair contract to support FLO, the Ferrovial Agroman/ Laing O’Rourke JV, with the repairs to the concrete ring segments constructed by the tunnel boring machines. Repairs include making good and waterproofing to cracks, gaskets, holes and any other damage through the entire length of the bored tunnels from Battersea to Kennington, both north and south bound. Repairs were completed with PU and acrylic resins.
