Company information
The construction method of this technique closes cracks and openings to prevent loosening of the rock due to weathering, while also dispersing concentrated stress in the area. It exhibits excellent durability against repeated loads such as earthquakes and demonstrates a high rockfall prevention effect. When applying this method, its features 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 fix 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, and the construction equipment is minimal, it can be easily combined with other methods.
