Summary

Newton Specialist Contractor, and injection resin specialist, ASF Waterproofing was brought in to repair structural cracks and concrete joints at Limehouse Link Tunnel. The busy London commuter tunnel that stretches beneath East London, was experiencing unwanted water ingress near the roof of the structure.

Context

The Limehouse Link Tunnel stretches 1.1 miles beneath East London, connecting The Highway to Canary Wharf in London Docklands.

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, a specialist in injection resins and structural repair work, worked with Newton Waterproofing to provide the waterproofing solution.

Solution

Following an initial investigation, ASF opted to inject PC Leakinject Uni 6816 E resin 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 was left with approximately a 4-hour window to carry out the works each night.

Outcome

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.
