Geoss Good Practice For Installation Of Jacked Foundation Piles In Singapore Repack Jun 2026

A successful jacked piling campaign relies entirely on accurate desk studies and soil investigation (SI). GeoSS emphasizes that saving costs on SI frequently leads to project delays and pile damage. Soil Investigation Protocol

A successful jacked piling campaign begins long before the rig arrives on site. Detailed planning prevents unexpected refusal or excessive soil displacement.

The pile is jacked into the ground using a continuous, controlled force. The reaction for this force is provided by the self-weight of the rig and its kentledge (up to 600 tonnes for high-capacity systems). A successful jacked piling campaign relies entirely on
