Why the press-in method?
Conventional piling drives the pile in with impact or vibration. That energy does not stay in the pile. It travels into the ground and into everything standing on it. Near housing, historic buildings or a live railway line, that is often the reason a project cannot go ahead as designed.
The press-in method removes the source. The SILENT PILER ™ grips the piles it has already installed and uses them as its reaction force, pressing the next pile in with static hydraulic force. No hammering, no vibration cycle.
Benefits of press-in piling on site
Work close to buildings and railways
Low noise and low vibration make it possible to build where conventional piling would be refused permission. Work can proceed next to residential streets, historic buildings and active railway lines without shutting them down.
A smaller machine and a smaller site
Press-in machines are lighter and more compact than conventional piling rigs. Less space is needed for the equipment itself, and less for the working area around it.
Stability from the piles already installed
The machine holds onto the piles it has already pressed in. This removes the risk of overturning and allows work on steep slopes, under bridges with limited headroom, and in narrow spaces.
Less disturbance to the ground
Static pressing causes significantly less ground disturbance than impact or vibratory methods, which matters where existing structures, embankments or buried services are close by.

GRB System
GRB stands for Giken Reaction-Force-Based System. The entire operation runs on top of the piles that have already been installed, and the working platform moves forward as the wall advances.
This removes the need for temporary access roads and work platforms. The area occupied by the site shrinks, fewer machines are involved, and there is no risk of the equipment overturning. On riverbanks and in built-up areas, where a conventional site would need to take over a large footprint, this is often the deciding factor.
