The solution
Thor Helical Remedial and Shire Piles were chosen by the project archaeologist and CADW for the foundation reinforcements. The Shire Piles were the preferred choice due to the minimal ground disturbance caused by the low displacement of the Helix product.
Contractors Antares Construction set the Piles to depths of 4-6 metres, giving compression capacity in excess of 50kN. The Piles were used in the ancient dock walls in addition to supporting the foundations of a new revetment being built within the existing moat. |
