Performance results of rockfall prevention construction methods for seismic resistance.
No changes even at seismic intensity 7! We would like to introduce the seismic performance results of our rockfall prevention construction method.
We would like to introduce the "Seismic Performance Achievements" of Daini Kensetsu Co., Ltd. Our rockfall prevention method is designed to withstand massive earthquakes and has proven effective in various locations across Japan. It showed no deformation even during the Great Hanshin-Awaji Earthquake, which registered a magnitude of 7 in 1995, and has successfully endured numerous earthquakes since, including the 2000 Tottori Prefecture Western Earthquake and the 2007 Noto Peninsula Earthquake. If you have concerns regarding rockfall prevention methods, please feel free to consult with us. 【Seismic Achievements】 ■ Great Hanshin-Awaji Earthquake (Magnitude 7) ■ Tottori Prefecture Western Earthquake (Magnitude 6+) ■ Geiyo Earthquake (Magnitude 6-) ■ Noto Peninsula Earthquake (Magnitude 6+) ■ Great East Japan Earthquake (Magnitude 6-) ■ Kumamoto Earthquake (Magnitude 7) *For more details, please refer to the PDF document or feel free to contact us.

Company information
The construction method described here prevents loosening of the bedrock due to weathering by sealing crack openings and dispersing concentrated stress in the area, making it highly durable against repeated loads such as earthquakes, and demonstrating a strong rockfall prevention effect. The features of this method include: 1. It can be applied to large rocks and high-altitude rocks that have high potential in mountain slopes and similar areas. 2. It can secure natural rock formations in their current state, and the construction traces harmonize with the landscape, making it particularly effective for use in natural parks and scenic areas. 3. Since there are no alterations to the natural features or new structures required, and the construction equipment is minimal, it can be easily combined with other methods.
