The construction consisted of using an F111 Silent Piler, capable of handling 400mm wide sheet piles, to install U-shaped sheet piles (17–27 m long) to form retaining walls in the construction of a new factory building.
The Press-In Method for sheet piling installation was specified in the project plans due to the adjacent proximity to the existing factory.

The Philippines is exposed to a high risk of severe and frequent natural hazards due to its geographical location in Southeast Asia. Typhoons, heavy rains, earthquakes, floods, volcanic eruptions, landslides, and fires are among the natural hazards that affect the country. The Philippine government’s Mines and Geosciences Bureau (MGB) reports that the country ranks fourth among Indonesia, India, and China in terms of landslide risk, with up to 80% of its total land area susceptible to landslides. Today, Mayon Machinery (“MMRI”)is pleased to introduce a solution to minimize the damage by taking immediate action with implant restraining walls over all phases of landslide prevention from mitigation to recovery. The Implant Wall, constructed using the “Press-in Method” invented by Giken in 1975, acts as a restraining wall of the “Guard Method” or “Rescue Method”. These methods are designed to carry out protective work before and after the occurrence of unpredictable natural disasters.
What’s Press-in Method?
The Press-in Method is one of the pile jacking methods that use a static jacking force to install piles into the ground. Its environmental impact of noise and vibration is smaller than those of conventional piling methods using drop hammers or vibratory hammers.
One of the characteristics of the Press-in Method that provides an essential difference from the other pile jacking methods is that a reaction force is secured from the previously installed piles.
Therefore, the space for piling and the cost of temporary works can be significantly reduced.
Exposition of the Solution “Implant Landslide Prevention Method”
The combination of the Implant Deterrence Piles and Implant Retaining Walls will prevent landslides caused by massive earthquakes and torrential downpours. Large preventive piles, with a maximum diameter of 2500mm, are embedded into the stable ground to hold soils and allow excessive groundwater to flow down through the pile gap. The Implant Retaining Walls act as a mass gravity structure providing stability to slopes against debris fall. Retaining walls can be over 9 meters high and support slopes by resisting lateral movement and pressure. They are pressed-in from the top of pile walls without disturbing daily life and the surrounding environment.
Methodology To Be Adopted in the Philippines
To build a strong continuous wall, called Implant Wall, in a hazardous location where there is a possibility and/or occurrence of landslides due to torrential rain, etc., the GRB system is used to significantly shorten the construction speed and reduce damage to people and property. It minimizes the working area to just the contact surface of the piles on the ground and eliminates the need for a temporary platform, even on slopes, uneven ground, and over water. If the situation changes after restoration, the wall can be removed for other purposes or moved to another location.
“Implant Wall” as a Measure for Landslides
However, the GRB system is also used in auto to press-in a PC (Precast concrete) wall structure, etc., that is resistant to high temperatures, high-pressure steam, and volcanic gas, causing a pyroclastic flow down the mountainside when a volcanic eruption occurs.

What’s GRB system?
The “GRB™ System”, which allows all machines to self-move on top of the installed piles, enables construction work to be carried out even in disaster-affected areas, slopes, and narrow sites (Fig. 1). As the influenced area of work is limited to the width of the machines, the work can be carried out without disturbing the traffic flow around the construction site.

Although landslides usually occur without warning, it is important to understand this natural hazard and create a comprehensive landslide risk mitigation framework. Utilizing Giken’s Implant Landslide Prevention Method ensures the sustainability and expansion of landslide risk reduction. The method is proven to be so efficient and applied to over 36 countries worldwide.

The Philippines is an island country consisting of some 7,400+ islands and islets and have a coastline of approximately around 37,000 km. However, flood risks due to natural coastal hazards (surges, typhoon waves, and tsunamis) threaten the loss of life and damage to the properties of its residents. To minimize devastating consequences, a disaster prevention levee is an important coastal protection solution by Giken’sInnovative Technologies. Implant Levee that is securely integrated with the Earth is highly resistant to ground displacement caused by the motion dynamic loss of external force such as earthquakes, and tsunamis, thus, serving as a ”resilient” disaster-prevention infrastructure.

What’s Implant Levee?
An implant levee is solid and strong against complex disasters such as earthquakes, tsunamis, and land subsidence. For earthquake protection, an implant-structured pile continuous wall has a secure embedded depth that will not allow any large deformation. Also, as the side floating of liquefied soil is restrained, settlement of the levee body is restrained. Furthermore, by embedding the pile toe to the non-liquefied layer, subsidence of the pile itself will not occur, and the levee height may be maintained. With tsunami, even if the slope face collapses due to overflow, the pile continuous wall with the implant structure will keep its form, and thus maintain its levee function. After an earthquake, tsunami, or other disasters an implant levee may be used as an emergency transit route or drainage work base for fire engines by erecting a coverage plate using the remaining pile heads. This way, it becomes useful in the early restoration of disaster sites.
Coastal Levee Protection Methods
Two methods presented here are commonly applied in coastal levee protection in many countries, including Japan:
Twin Sheet Pile Walls
Tubular Pile Wall
Steel sheet piles are installed into the embankment to a depth determined for proper stability and/or cut-off of flow. Also, liquefaction of the levee can be prevented by enclosing it with twin sheet pile walls. Thus, the levee can withstand large external loading and the levee crest can remain in place, even in catastrophic events.
Steel tubular pile wall is a vertical barrier and can be installed in locations where space is scarce, such as urban environments or where the construction of a wide levee is not feasible. The piles are installed into the embankment to a depth determined for proper stability to withstand large dynamic and hydraulic loading.
Giken Reaction Base (GRB) System
Gyropress Method
The press-in machine utilizes reaction force from previously installed piles and performs piling work on top of the piles. With further development based on the principle of “reaction-based mechanism”, “the GRB System” was developed as a press-in system that performs all piling procedures such as; pile transportation, pile pitching, and press-in work, on top of installed piles. The GRB System consists of a Silent Piler in the front, a Power Unit as a power source, a Clamp Crane to pitch piles, and a Pile Runner to convey piles from the storage site.
Gyropress Method installs tubular piles with cutting bits attached on pile toe by the rotary jack-in system and travels on top of piles that are completely installed (completed piles). Gyropress Method allows the installation of tubular piles without prior removal of existing structures and/or obstacles.
