Jacked piles are typically prefabricated steel or concrete sections that are pushed into the ground using hydraulic jacks reacting against the weight of the rig or anchored to the ground. They are ideal for sites with sensitive adjacent structures, strict noise ordinances, or where vibration monitoring is critical.
: Jack-in machines are heavy and require a stable, reinforced working platform to prevent the rig from tilting or sinking during operation. Jacked piles are typically prefabricated steel or concrete
