Jacked piles (commonly known as "Jack-in Piles") are a widely used foundation system in Singapore, particularly for residential and commercial projects where noise and vibration must be minimized. Unlike driven piles which use impact, jacked piles are installed by hydraulically pushing the pile into the ground using static force.

: Operational use must not exceed 75% of the machine’s maximum capacity .

Static load tests are recommended to determine the ultimate pile capacity, ensuring that the piles are installed using the same method as in the tests.

Jacked piling uses hydraulic rams to press precast concrete or steel piles directly into the ground. This technique provides unique mechanical advantages and requires strict adherence to specialized operational parameters.

After placing or advancing a piling frame, an inspection and correction of the footing must be carried out to ensure stability.

Measures the jacking force continuously, providing immediate feedback on soil resistance.

Artificially inflates or reduces short-term resistance readings.

back to zero and immediately re-applying it without a pause. This multi-cycle compression ensures the pile pierces through temporary soil setup or skin-friction lockups to reach the true load-bearing strata.

:

Piling work must be supervised by competent and suitably qualified persons with comparable experience, as required by BS EN 12699. The site supervisor’s responsibilities include:

In Singapore, jacked piles are particularly advantageous in with nearby structures and sensitive residents. The jacked piling system uses dead weights to exert hydraulic pressure to push piles into the ground, producing less noise and vibration compared to driven piles, making it suitable for projects in urban areas where residents are sensitive to noise and vibrations.
