The "Ishigaki PB" is a curved block with a cylindrical shape that allows for the filling of internal infill material. Due to its cylindrical shape, adjacent blocks can be arranged in contact with each other at any position within a 360-degree range. This allows for the formation of curves not only in the vertical direction of the retaining wall but also within the horizontal plane, enabling the construction of three-dimensional curved retaining walls. 【Features】 ■ Cylindrical shape ■ Can be filled with internal infill material ■ Can be arranged in contact with each other at 360 degrees ■ Capable of constructing three-dimensional curved retaining walls ■ Enhances the connection strength between adjacent blocks *For more details, please refer to the PDF document or feel free to contact us.

"My Dokko" is a foundation method designed for use on weak ground. Horyu-ji Temple's five-story pagoda, the world's oldest wooden structure. The 1200-ton pagoda has withstood wind, snow, and major earthquakes for 1400 years without experiencing differential settlement, and it still maintains its grandeur and beautiful appearance. The "stone method," which involves laying stones on the foundation ground, is the wisdom of our predecessors. The "Top Base Method 'My Dokko'" has revived this wisdom by harmonizing and rationalizing it with other excellent methods for modern use. [Features] ■ Safely supports superimposed loads even on extremely weak ground ■ Earthquake resistance can be expected due to vibration absorption and shock prevention effects ■ Construction is possible within buildings and on narrow sites ■ Reduces settlement and prevents differential settlement ■ Easy to install without the need for special machinery *For more details, please refer to the PDF materials or feel free to contact us.

The "V-Rock" is a block developed with a focus on improving workability, including safety during installation, fine adjustment movement during placement, and the fluidity of the core concrete. The protrusions and grooves provided on the block make it easy to position the blocks during installation, significantly enhancing workability as it can also accommodate curved sections. Due to the V-shaped design of the supporting beam, pouring the core concrete becomes easier, and the block masonry wall structure becomes highly integrated. 【Features】 ■ Large masonry blocks at 1.6 pieces/m² shorten construction time compared to conventional products. ■ It is self-supporting and level, ensuring safety during installation. ■ Positioning during installation is easy due to guide protrusions. ■ It can accommodate curved sections. ■ The block masonry wall structure has a high degree of integration. *For more details, please refer to the PDF document or feel free to contact us.

"Jelok" is a large connected block that integrates artificial rock blocks with beams. Due to its monolithic structure, there is no dimensional deviation, and it can be used on slopes from horizontal to a 10% gradient. The large void ratio allows plant roots to easily take hold, and the compacted soil is less likely to wash away, making it suitable for vegetation and greening due to its uneven shape. Additionally, the varied arrangement of artificial rocks creates a more natural landscape. 【Features】 ■ Strong connection structure ■ Accurate layout is possible ■ Effective greening is achievable ■ Harmony with the landscape is possible *For more details, please refer to the PDF materials or feel free to contact us.

The "Step Block" is a stair block utilized at the riverfront. The combination of "Slope Stepper" forms a connected structure, and the weight of each individual block contributes to the construction of a robust riverbank. Additionally, the arch-shaped recess on the front has an appropriate roughness that provides hydraulic effects. It is suitable not only for riverbank protection but also for recreational facilities such as parks, riverbanks for sports fields, fishing parks, boat landing areas, and spectator seats for event venues, as well as rivers and lakes that require fish habitat protection. 【Features】 ■ Construction of a strong riverbank ■ Establishment of a riverfront system ■ Ensuring safe ascent and descent ■ Providing habitat space for fish ■ Quality assurance through factory production *For more details, please refer to the PDF materials or feel free to contact us.
