Giken SuperCrush Silent Piling Solutions For a vibration-free and ultra-low noise installation of steel sheet piles into hard ground.

Standard press-in piling uses hydraulic force to push sheet piles into the ground. Supercrush adds an integral rock auger housed within a casing, which works immediately ahead of the pile as it is pressed in. This reduces resistance at the pile toe and extends the press-in method to harder ground where additional penetration assistance is needed.

Supercrush is designed to assist sheet pile installation in hard or challenging ground, including suitable rock conditions. It can be used in both cohesive and granular soils. Suitability depends on the ground profile, rock properties, pile specification and required depth, so the ground investigation must be reviewed before confirming the installation method and equipment.

No. Auger assistance can help with challenging ground, but it does not mean every buried obstruction can be passed safely or without additional work. Information about existing foundations, buried services and other obstructions remains important. Ivor King reviews the available site information to assess whether Supercrush is appropriate and whether further investigation or preparatory work is needed.

Supercrush can be considered where reducing pile-driving noise and vibration is important, including near residential properties and basement works. It combines hydraulic pressing with augering instead of conventional impact or vibratory driving. Supporting plant and site activities still generate noise, and the working method must account for nearby structures, ground conditions and the project’s specific constraints.

Yes, where the site and piling arrangement are suitable. GIKEN equipment can work remotely from access roads and is used for installations over water or where working space is limited. The initial setup, pile deliveries and supporting equipment still require planning. Ivor King assesses these practical requirements alongside the ground conditions before recommending the system.

Useful information includes the ground investigation and any rock testing, proposed pile line, sheet pile sections and required depths. Details of buried services, known obstructions, nearby structures, access and the construction programme also help. Where piles must carry vertical loads as well as retain ground, share those requirements so they can be considered in the design.
