Richmond Upon Thames, London – Permanent sheet piled basement cofferdam with a silent and vibration-free piling rig
We were engaged by J Reddington Ltd to provide a water tight steel intensive sheet piled basement on the site of the old Teddington Studios, London. Some 750 piles in lengths between 6.5m to 12m were driven in 4 weeks. Two Silent and Vibration-free rigs were used to drive the piles after first pre-augering the granular soils overlying the London clay.
Due to the depth of the new basement the piles had to be propped in the temporary condition. However, as space to the perimeter allowed, on this occasion temporary ground anchors were utilised by being fixed through the concrete capping beam. To ensure water-tightness all the pile clutches were seam welded.
