Simultaneously achieve environmental vibration reduction and liquefaction prevention in transportation, factories, and construction! Reliable technology for safety measures! Our company's unique improved ground construction method.
E&D Tech Design Co., Ltd.'s "WIB Method" is an improved ground construction technique that reduces environmental vibrations from traffic, factories, and construction, as well as seismic shaking, while addressing liquefaction issues 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, allowing for overall cost reduction. 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 ■ Prediction and design of vibration reduction values 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.

Company information
E&D Tech Design Co., Ltd. is a company that theoretically creates stable ground that is resistant to shaking and less prone to liquefaction by using its advanced proprietary technology known as the "WIB method." Focusing on vibration control, vibration reduction, and soundproofing against low-frequency vibrations from transportation, construction work, and factories, as well as seismic resistance and isolation against earthquakes, we conduct measurement surveys, simulation analyses, and design and construction of countermeasure methods. We aim to protect a comfortable environment through ground design and assist in creating happiness.
