Compensation Grouting Win

Keller UK ("Keller") has been awarded the compensation grouting works at London Underground's Tottenham Court Road and Bond Street stations. The contract covers the installation of over 50 kilometres of specialist pipe (tube-a-manchette), through which grout will be pumped whilst the tunneling works are in progress, to mitigate any ground movement and protect the existing infrastructure.

Keller has also been awarded a contract for structural monitoring, geotechnical instrumentation and surveying works, employing Getec the monitoring system which was originally developed by Keller in Germany and recently introduced into the UK.

The two contracts will be undertaken in joint venture and have a combined value to Keller of around £30m. Work on both will begin shortly and will run through to 2014
