Galliford Try success with new tidal technique

Contractor Galliford Try has just completed work on four tidal wall upgrades on the River Thames for the Environment Agency.

Work on the Vaizeys Wharf site made use of a a Giken vibrationless piling rig to repair the dilapidated 25m frontage of the pub car park and upgrade it with a biodiversity terrace.

According to Galliford, the site at Vaizeys was very small and it was essential that the work did not impact on the pub’s business during the construction, which meant the vibrationless system was the most suitable method. There were also archaeologically significant sailing ship timbers immediately to the front of the site on the foreshore and part of the challenge was to carry out the work without disturbing these.

The other three sites at Moreden Wharf, Laporte and Rainham also involved repairing the old sheet piled frontages. At Rainham, Galliford carried out the work by welding new steel plates to the face of the existing sheet piles along a 500m frontage and filling the space between with concrete.
