Jacked-Down Piles
So, What Is Jack-Down Piling?
Jack-down piling (also known as hydraulic jacked piling) involves pressing piles into the ground using hydraulic jacks rather than driving or drilling. The pressure is applied gradually and precisely, using the structure or platform’s weight as a reaction force.
This method is especially effective where vibration or noise must be avoided, and where working platforms — like barges or jetties — are used.
How We Solve Your Problems
✅ Need Zero-Vibration Installation?
Jack-down piling is completely vibration-free — ideal for working near sensitive structures, utilities, or in urban environments.
✅ Working Over Water or Soft Ground?
This system excels in marine and soft ground conditions where driven or bored methods aren't practical or permitted.
✅ Worried About Noise or Community Disruption?
Jack-down systems are exceptionally quiet, making them a top choice for inner-city, residential, or live operational areas.
✅ Not Sure if It’ll Work on Your Site?
Our experienced team will assess the load requirements and platform constraints to determine if jack-down is the right fit — and if not, we’ll recommend the best alternative.

Frequently asked
questions
Why is this method considered vibration-sensitive?
Jacked-Down Pre-cast Piles are installed without the need for heavy impact driving, significantly reducing vibration and making them suitable for sensitive sites.
How does using Jacked-Down Pre-cast Piles minimise disruption to surrounding structures?
This method uses hydraulic jacking to press piles into the ground quietly and smoothly, avoiding vibrations that could disturb nearby buildings or infrastructure.
What are the advantages of using pre-cast piles over other piling methods?
Pre-cast piles offer consistent quality, quick installation, and high load-bearing capacity, along with reduced noise and vibration during installation.
How deep can Jacked-Down Pre-cast Piles typically be installed?
These piles can generally be installed to depths of up to 12 meters, depending on soil conditions and load requirements.
What types of soil conditions are suitable for this type of piling?
Jacked-Down Pre-cast Piles are suitable for various soil types, particularly in firm to stiff soils and in conditions where low disturbance is essential.
