Stone masonry (stone wall) repair and restoration using the Rock Bond DK method.

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 rock bonding DK bond method is a technique that stabilizes unstable rock masses by using an adhesive material (DK bond mortar) to bond and integrate them with stable bedrock. 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, requests for construction on stone walls have also increased due to the inconspicuous nature of the work. This time, we carried out construction at Asaharubashi in Takaoka Kojo Park, Takaoka City, Toyama Prefecture. DK bond mortar was filled into the empty spaces of the bridge pier. *Please refer to the related catalog for construction photos.
