Added construction results for stone wall (stone masonry) repairs【Odawara Castle Goyomei Kurwa】.
The Rock Bond DK method is a technique that stabilizes unstable rock masses by bonding them to stable bedrock using an adhesive material (DK Bond Mortar). Since the first public works project implemented in Okayama Prefecture in 1977, there have been approximately 3,700 construction achievements across all 47 prefectures in Japan by June 2020, spanning over 40 years. In addition to construction on rock masses and boulders, there has been an increase in requests for construction on stone walls due to the inconspicuous nature of the work. This time, we carried out construction at the rice granary of Odawara Castle. *Please refer to the related catalog for construction photos.

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.
