Contributing to vibration, liquefaction, and differential settlement measures! WIB method [Helpful materials provided]

Can be used for residential areas, facilities, and roads! Enhances the bearing capacity of weak ground and prevents building settlement and liquefaction.

The "WIB method" is a ground vibration mitigation technique that constructs a rigid plate-like or wall-like cellular structure (WIB structure) at the required depth underground using ground improvement piles. This method reduces environmental vibrations from road traffic, railways, construction work, factories, events, and seismic forces on structures during earthquakes. It consists of a replacement soil (vibration isolation layer) that suppresses and blocks the propagation of ground vibration waves, and a cellular structure (damping layer) that absorbs and blocks vibrations. The combined effects of vibration isolation and damping achieve the target vibration reduction. Additionally, it simultaneously exhibits the effects of "vibration mitigation" (improving vibration environments and reducing seismic motion), "liquefaction countermeasures," and "uneven settlement countermeasures," thereby keeping the overall ground improvement costs low. 【Features】 ■ Usable for residential areas, facilities, and roads ■ Reduces seismic forces on structures during earthquakes ■ Enhances the bearing capacity of soft ground, preventing building settlement and liquefaction ■ Keeps overall ground improvement costs low *For more details, please refer to the PDF materials or feel free to contact us.

Improved Ground Improvement Method "WIB Method" [Helpful Materials Available Now!]

Simultaneously achieve environmental vibration reduction and liquefaction prevention in transportation, factories, and construction! Reliable technology for safety measures! This is our company's unique improved ground improvement method.

E&D Tech Design Co., Ltd.'s "WIB Method" is an improved ground method that reduces environmental vibrations from traffic, factories, and construction, as well as seismic shaking, while addressing liquefaction and enhancing and stabilizing the bearing capacity of weak ground. By using a rigid cell-type plate or wall structure, it simultaneously achieves liquefaction prevention and differential settlement prevention, making it a cost-effective method overall. Additionally, it can also address micro-vibrations that interfere with the operation of precision machinery and medical devices in high-tech industries. 【Features】 ■ Liquefaction prevention through strain suppression of the ground using a cell-form structure ■ Differential settlement prevention through improved horizontal bearing capacity of the ground using a plate structure ■ Vibration reduction value prediction and design based on ground surveys, achieving set targets ■ Recipient of the Minister of Education, Culture, Sports, Science and Technology Award for Scientific and Technological Achievement in 2011 ■ Capable of addressing micro-vibrations that affect medical devices *For more details, please refer to the catalog or feel free to contact us.
