The Limehouse Link Tunnel stretches 1.1 miles beneath East London, connecting The Highway to Canary Wharf in London Docklands. The main contractor, RMS (A13) Plc, contacted Newton Specialist Basement Contractor ASF Waterproofing regarding repairs to the entrance of the tunnel, where there was evidence of water ingress.
ASF Waterproofing, who are specialists in injection resins and structural repair work, worked with Newton Waterproofing to provide a suitable waterproofing solution. Following an initial investigation, ASF opted to inject Newton 320-FP into the structural cracks and concrete joints.
As the water ingress was located near the roof of the tunnel, it needed to close for the repairs to be carried out. This was only possible between 11pm and 4am to minimise disruption to the roads of London.
ASF required a cherry picker and scissor lift to reach the area, so after set up and leaving time to clear the site, ASF were left with approximately a 4 hour window to carry out the works each night.
Newton 320-FP is part of TRADECC's high performance specialist injection resin range for water sealing, soil consolidation, structural repair and concrete repair products. Forming a hard, high-strength seal within structural cracks and joints, 320-FP penetrates deep into the substrate in order to stem the flow of unwanted water ingress and return the structure to full working order.
Considering the challenging time windows presented to ASF, the project was completed in a timely manner, with both the tunnel and the vehicles that use it now protected from unwanted water ingress.
