Unlike bored piling which generates wet soil slurry, jacked piling displaces soil laterally, keeping the job site dry and reducing waste disposal costs.

: Jacking rigs are exceptionally heavy, often weighing between 150 to 600 tonnes. The working platform must be designed and certified by a Professional Engineer (PE) to prevent rig tilting or ground bearing failure. Selection and Inspection of Materials and Equipment Increases risk of pile buckling or deviation under peak load

All jacked piles should be installed to an appropriate depth into a suitable bearing stratum as determined by the geotechnical engineer or local practice.

: Ensure the working platform is of high quality, specifically regarding compaction and site drainage , as jacked machines can be extremely heavy. The working platform must be designed and certified

The Geotechnical Society of Singapore ( GeoSS ) has established specific guidelines for the installation of jacked foundation piles to ensure structural safety and serviceability within Singapore’s unique geological landscape. Jacked piles are favored in urban areas due to their , negligible vibration , and minimal soil disposal . 1. Pre-Installation and Ground Considerations
