Ivor King are industry leaders in the use of Giken Supercrush Silent Piling technology – a further development of the vibration-free piling process, utilising an integral rock auger housed inside a casing to penetrate hard ground.
The press-in action is carried out while simultaneously augering the ground immediately ahead of the sheet pile. This technique enables silent piling into hard or challenging ground, up to and including rock, and allows sheet piles to be designed to take significant vertical loads.
This technology uses the unique concept of ‘Coring Theory’ whereby the hydraulic press-in simultaneously takes place with augering. This makes sheet pile installation possible in very hard ground conditions, enabling the vibration-free installation of sheet piles in otherwise impossible conditions.
This method allows silent/vibration-free pile installation in both cohesive and cohesionless soils, with SPT values from N = 0 – 100+ and hard rock with UCS results up to 90MPa.
