"Eco Choi-Nose" is an environmentally friendly block that improves construction efficiency through horizontal stacking and ensures construction safety. With a shape designed for a 5-degree and 3-degree slope in horizontal stacking, it excels in both workability and safety, and the use of foundation blocks further enhances construction efficiency. Additionally, the product allows for the creation of diverse environments while ensuring the safety of the embankment. [Features] ■ Improved workability through horizontal stacking ■ Ensures construction safety ■ Enables the creation of diverse environments ■ Wall weight is greater than that of conventional block masonry ■ The width of the wall vegetation section is a maximum of 20mm, preventing the outflow of filling materials *For more details, please refer to the PDF document or feel free to contact us.

The "TB (Touch Bond) Method" is a seismic jointing method that achieves resistance to level 2 earthquake motions by connecting with a one-touch joint and bonding with a highly elastic adhesive that excels in elongation capability. Connection is completed simply by pushing the joint bar into the socket, and then injecting the high-elasticity adhesive into the designated space. Compared to conventional methods, this significantly reduces the amount of work required, improving construction efficiency and cost-effectiveness, and shortening the construction period. 【Features】 - Improved construction efficiency and cost-effectiveness, shortened construction period - Clears level 2 earthquake motions - Continuity, water tightness, and seismic resistance on all bonding surfaces - Water tightness equal to or greater than elastic sealing - Accommodates shear displacement *For more details, please refer to the PDF document or feel free to contact us.

• Earthquake-resistant construction method

The "H-type PC pile" is a small-diameter concrete pile used for ground reinforcement in small-scale buildings such as single-family homes. The construction method for the "H-type PC pile" has obtained a building technology performance certification from the Japan Building Disaster Prevention Association, ensuring high reliability. It is a PC pile with a concrete compressive strength of Fc = 50 N/mm², which excels in impact resistance and poses no risk of cracking during handling. Due to its H-shaped cross-section, it has greater surface friction than cylindrical piles, supporting the building through the tip resistance of the ground and the surface friction force. It is produced under strict quality control in a JIS-certified factory, making it a highly reliable ground reinforcement material. 【Features】 ○ H-PV method GBRC performance certification No. 05-17 revised 2 ○ H-AP method GBRC performance certification No. 06-23 revised ○ The pile driver is compact, allowing for construction in narrow sites ○ The hydraulic insertion method enables construction with low vibration and low noise For more details, please contact us or download the catalog.
