The confined ground seismic damper is ground seismic dampening technology that mitigates the impact of earth movement and minimises displacement of structures, by confining the ground with a continuous wall made of the Implant Structure.

In order to prevent damage caused by liquefaction, the area surrounding the installation site can be enclosed using sheet piles. This method doesn't require any treatment to be done on structures such as facilities, railways, roads, etc. that are otherwise susceptible to liquefaction damage. It's a simple and cost-effective process that can restore the ground to its original state by removing the sheet piles. This environmentally-friendly method can be used to counteract liquefaction for all types of existing infrastructure, whether it's above or below ground.

With the synergistic effect of the “Ring Method”, which is used to control liquefaction by cylindrically enclosing the installation site of outdoor storage tanks such as those at a Petrochemistry complex, and the “Lateral Soil Flow Restraining Pile Method”, which minimises the lateral flow of surrounding ground, the entire facility is kept safe.

The embankment construction method has been widely used since ancient times, but has disadvantages, such as requiring a large amount of soil, which is taken from countryside areas with an abundance of nature, using a lot of energy, and requiring a lot of effort and time. Accordingly, we constructed a retaining wall with high earthquake resistance, by pressing in structural　members produced at the plant with the minimum necessary soil. Instead of using soil inside the wall, we used plastic bottles, urethane waste, plastic, etc, and so were able to complete the embankment rapidly without causing any further damage to the nature.

Towards the end of the 20th century at the dawn of the IT age, intelligent buildings were born one after another in cities. In the 21st century, in response to the rapid progression of IT, it is predicted there will be the advent of an age of super intelligent buildings with built-in underground shelters for protecting the irreplaceable assets of companies, such as the lives of employees and supercomputers. A lesson from the 9/11 terrorist attacks that shook the world was that it is necessary to be ready to deal with threats such as chemical and biological weapon attacks and cyber terrorism, as well as natural disasters such as fire and flood. Trust cannot be placed in companies that cannot guarantee safety. This should become common sense in the 21st century.

Provided you have an antiseismic foundation using the Implant Structure, it will function as a support for the building in normal times, while the internal space can be used for various purposes such as meeting rooms and underground parking, and in times of emergency, it can be used as an underground shelter.
