Flood damage countermeasures - Fill-type elevation method "Bulk Up Method" NETIS registered

Flood damage countermeasures - Fill-type elevation method "Bulk Up Method" NETIS registered

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.

Impact on the durability of the coating / Preparation of the substrate is necessary.

Impact on the durability of the coating / Preparation of the substrate is necessary.

Proper adjustment of the substrate is essential for maintaining the durability and lifespan of the paint.

The lifespan of metal coatings is generally considered to be around 10 to 30 years. The factors that influence this lifespan can be broadly categorized into the following four: Surface Preparation: Proper adjustment of the metal surface before painting is crucial. Cleaning and treating the surface improves the adhesion and durability of the coating. Number of Coats: It is also important to adhere to the appropriate number of coats. Ensuring sufficient coating thickness enhances the corrosion resistance of the metal. Type of Paint: The type of paint used significantly affects the lifespan. It is necessary to select appropriate paint that matches the metal's usage environment, considering factors like weather resistance and chemical resistance. Painting Techniques, Climate, and Surrounding Environment: The skills used in the painting process and the construction environment are also important factors. By employing appropriate painting techniques and considering climate conditions and the surrounding environment, the quality and lifespan of the coating can be improved. By properly managing these elements, the lifespan and corrosion resistance of metal coatings can be maximized. For more details, please refer to the PDF below.

Primer required, prevents peeling.

Primer required, prevents peeling.

If you apply topcoat paint without a primer, it will peel off. Compared to products that have both primer and topcoat, those without primer have weaker adhesion to the substrate, making the paint film more prone to peeling.

When comparing products that only have a topcoat without a primer to standard painting products that include a primer, it was found that the products without a primer easily had their paint film peel off. Primer paint has the dual effect of preventing rust and strongly adhering to the substrate and base material, so it cannot be omitted. Although the primer is not visible, it plays an important role in maintaining corrosion resistance. Additionally, if the primer is not applied properly, the topcoat may be applied unevenly or show inconsistencies, resulting in an unattractive finish. Furthermore, the primer enhances the permeability of the paint, allowing the topcoat to adhere better, which can improve the durability and anti-corrosive properties of the paint film. In other words, the primer is a crucial step that significantly affects not only the appearance but also the performance and lifespan of the paint. Therefore, omitting the primer greatly increases the likelihood of having a paint job that peels easily or products that are prone to rust, making it essential to always apply an appropriate primer.

The relationship between blasting and painting.

The relationship between blasting and painting.

In painting, proper surface preparation (substrate treatment) is essential to achieve a good finish. The most effective method for surface preparation is blast treatment.

"Surface preparation" refers to the process of preparing the underlying material or substrate. Metals are melted, cooled, and solidified during the manufacturing process, but when exposed to high temperatures, they combine with oxygen in the atmosphere to form a film known as an oxide layer. If painting is done without removing this oxide layer and impurities, contaminants will mix between the paint and the substrate, leading to poor adhesion. Additionally, the functionality of the paint will not be realized due to the influence of impurities, preventing it from performing as intended. However, by using blasting to prepare the substrate, the surface oxide layer, rust, and other contaminants can be completely removed. Furthermore, by using angular abrasives, countless fine irregularities are created on the substrate, increasing the surface area for paint adhesion and preventing peeling. By cleaning and preparing the substrate with blasting before painting, the lifespan of the paint film can be extended two to three times, providing long-term economic benefits.

Pre-boring foundation stabilization method "NEW Super FK Method"

Pre-boring foundation stabilization method "NEW Super FK Method"

Supports a wide range of variations! Simple construction that meets the needs of the times.

The "NEW Super FK Method" is a pre-boring ground improvement method that integrates the foundation with the ground using segmental piles to develop bearing capacity. Since it involves straight excavation, the construction process is not complicated, which improves construction efficiency. Additionally, high blast furnace cement is used for the pile-fixing fluid and the ground improvement fluid, contributing to a circular economy through resource recycling. 【Features】 ■ By using an expansive admixture in the injection fluid, high frictional force is generated. ■ Pile sizes can accommodate from 300450 to 10001200. ■ Connection between intermediate and upper piles is possible for three types of pile diameters (shaft diameter, intermediate diameter, and segment diameter). *For more details, please download the PDF or feel free to contact us.

STJ Method for Expanding and Reinforcing Underground Excavation

STJ Method for Expanding and Reinforcing Underground Excavation

Excavated soil is natural soil! A reliable method for constructing expanded bulb foundations through the middle excavation and reinforcement technique.

The "STJ Method" is a construction technique that involves high-pressure injection of cement milk from an STJ bit to create an enlarged bulb, integrating it with the ground to develop bearing capacity. By switching the auger's rotation to a low speed and jetting cement milk from two high-pressure injection nozzles while pulling it up at a constant speed, it is possible to reliably construct an enlarged bulb. Compared to the pre-boring method, it is a low-discharge method, and the discharged soil is natural soil, contributing to a circular economy. 【Features】 ■ Low noise and low vibration method ■ Reliable construction of enlarged bulbs ■ High bearing capacity ■ Rapid construction ■ Low construction costs *For more details, please refer to the PDF materials or feel free to contact us.

Pre-boring expansion grouting method "Hyper-Straight Method"

Pre-boring expansion grouting method "Hyper-Straight Method"

Simple construction! Pre-boring enlarged foundation method using standard prefabricated concrete piles.

The "Hyper-Straight Method" is a pre-boring expansion solidification method where the ground is first excavated using an auger, followed by the injection of solidification liquid and pile surrounding fixation liquid, allowing the pile to be inserted into the designated support layer by self-sinking or rotation to a depth of 1D or more. Using a drilling and mixing device composed of an auger head, screw, mixing rod, and connecting rod, the construction is carried out through a sequence of steps from excavation to the injection of solidification liquid, repeated solidification of the solidified section, injection of pile surrounding fixation liquid, repeated fixation of the surrounding section, and installation of the pile. Additionally, by introducing a construction management system that supports high precision and efficiency, real-time management of the solidification bulb section and support layer is conducted to ensure quality. 【Features】 ■ Pile tip bearing capacity coefficient α=363 ■ Simple construction ■ Use of standard precast concrete piles ■ High bearing capacity at low cost ■ Construction management *For more details, please refer to the PDF document or feel free to contact us.

Pre-boring expansion grouting method "High Beam Method"

Pre-boring expansion grouting method "High Beam Method"

Proposal for "High Support Capacity Pile Design" with consideration for the environment! Introduction of the Pre-Boring Expansion Foundation Method.

The "High Bearing Capacity Pile Method (H・B・M)" enables the reduction of pile diameter and the number of piles used through high bearing capacity pile design, achieving a shortened construction period for foundation work and a reduction in excavated soil. By adopting HB piles with enlarged diameters, it obtains the specified values of the astonishingly high bearing capacity coefficients α, β, and γ (as per the Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1113). To match the large ground bearing capacity, ultra-high-strength concrete piles with a strength of over 105 N/mm² have been developed, and a group of manufacturing factories affiliated with the association provides high-quality products. 【Features】 ■ Ensures ultimate α, β, and γ values ■ Constructs environmentally friendly foundations ■ High-quality construction covering all of Japan ■ Concrete pile materials entering a new era ■ 8 types of selection variations *For more details, please refer to the PDF materials or feel free to contact us.
