Flood damage countermeasures - Fill-type elevation method "Bulk Up Method" NETIS registered
Bulk-up construction method NETIS registration number KK-220071-A
A new method for raising buildings in flood-prone areas significantly shortens construction time compared to existing elevation methods, reduces the amount of work required for house relocation, and has a major impact on costs. Registered in NETIS.
Until now, elevation work in flood-prone areas has involved either moving buildings sideways or lifting them up and raising the ground with fill. When moving a building sideways, proper site preparation can be done, but in places where there is no space to move, site preparation is carried out under the lifted building, making construction difficult and often resulting in insufficient compaction. If water seeps in the future, there remains a risk of building settlement. The "Bulk Up Method" involves lifting the building along with its foundation, leveling it to the required height, and fixing it in place, while filling the space between the foundation and the existing ground with bulk-up material as a substitute for fill. **Features:** - NETIS registration KK-220071-A, recommended by the Ministry of Land, Infrastructure, Transport and Tourism - Since water cannot permeate, the ground does not loosen even if it is submerged. - Its lightweight reduces the burden on the original ground. - Reduces the cost burden of elevation work in house-moving projects. - Can be implemented in narrow spaces. - Shortens construction time. - Reduces damage to the building since it is lifted with the foundation. The bulk-up material is a cement-based filler that expands to 1.5 to 1.7 times its original volume after filling, leaving no voids. After elevating the building, surrounding exterior works and retaining walls can be constructed.

Applications/Examples of results
- When raising is necessary due to flooding - Raising in places where traditional house-moving methods are not possible (narrow spaces where the building cannot be moved, where raising the building prevents construction work, etc.) - Can also be implemented as a correction for settlement levels - Can be widely applied to structures and objects - When wanting to keep raising costs down - When wanting to shorten the construction period - When raising in conditions where sufficient embankment cannot be made - When there are concerns about consolidation settlement after raising a heavy building - If you are considering a raising method that minimizes damage to the building as much as possible
Detailed information
-
Lift the building along with its foundation to the high water line and secure the building level horizontally. By lifting the building with its foundation, damage to the building is minimized.
-
Formwork will be installed around the building. It will be placed slightly away from the foundation to allow for visual inspection of the filling.
-
The bulk-up material is filled from the outside and inside. The bulk-up material expands its volume by 1.5 to 1.7 times after injection, leaving no gaps. It is lightweight and strong enough to serve as a substitute for soil.
-
The formwork has been removed, and it is complete. After this, we will proceed with the surrounding embankment, water supply and drainage, and structural work. Since the building is already in place, construction will be easier.
-
It is a 60cm elevation. There is no water infiltration, and it has strength, so future consolidation settlement will not occur.

Company information
Founded during the Meiji era, we started as a scaffolding business. During World War I and World War II, we worked on repairs of bombed railways and bridges, as well as infrastructure projects. After the war, we dedicated ourselves to the reconstruction of the country, and in 1948, we carried out numerous repairs and relocations of houses during the recovery efforts following the Fukui earthquake. We also contributed to recovery work during the 2007 Niigata Prefecture Chuetsu-Oki earthquake and assisted with ground measures for nuclear reactors. Currently, we specialize in house relocation work, building subsidence correction, ground subsidence measures (utilizing house relocation technology to allow for construction even after new builds or renovations), comprehensive civil engineering and construction, ground improvement and investigation services, and heavy object relocation. In renovation projects, we assess the necessary work for buildings and propose optimal construction solutions. Our work in the repair of shrines, temples, and cultural properties has been highly regarded, and we have received numerous letters of appreciation. In recent years, we have carried out house relocation work for the major restoration of the Mieido Hall at the World Heritage Site, Nishi Honganji in Kyoto, and also completed object relocation work at the World Heritage Site, Kamigamo Shrine in Kyoto. Our company conducts comprehensive operations based on the rich experience and technical skills cultivated over many years of history.
