The "FPU Side Ditch" is a type of ditch that utilizes a deep groove design, allowing for easy slope adjustment on-site. By utilizing the alignment prevention section between the ditch and the cover, it is possible to collect surface water into the ditch through the cutout on the side of the cover. Additionally, since the cutout on the cover is vertical, it allows for the linear collection of surface water, making it less prone to clogging. 【Features】 ■ Soundproofing function ■ Water collection function ■ Cost reduction ■ Adjustable slope ■ Barrier-free *For more details, please download the PDF or contact us.

• Gutters and U-shaped gutters
• Road construction

"JNS" is a large (jumbo) NS drainage channel developed as a rational and economical product primarily for longitudinal vehicle use, suitable for various purposes. Rubber sheets are fixed during molding in the lid section to prevent noise. Additionally, the height of the drainage channel is designed in 10 cm increments, similar to conventional products, allowing for flexible drainage gradients. 【Features】 ■ Drop lid type structure designed for 20-ton vehicles ■ Water flow cross-section is a vertical rectangular section ■ Proper design of flowing water gradients is possible ■ Compared to U-shaped channels with lids, the amount of lids is halved, reducing noise ■ Rubber sheets are embedded in the main lid section for further noise reduction ■ Inserts are embedded in the lid plate to streamline installation *For more details, please download the PDF or contact us.

The "Slim Block" is a self-stabilizing block that can be used with traditional design methods for masonry blocks. It can stand independently at a 5-degree slope and can be easily constructed with machinery, even without specialized masonry skills. This allows for labor-saving and faster construction, as well as reduced costs. 【Features】 ■ By using a dedicated lifting device for installation, the placement of the blocks becomes more reliable, easier, and quicker. This also improves workability and safety. ■ Natural stone surfaces are adopted to better match the natural environment. ■ The foundation part is precast, further enhancing labor-saving and shortening the construction period. *For more details, please download the PDF or contact us.

The "Porous Slim Block" is an environmentally friendly block that adopts a natural stone surface and is designed in dark colors to blend with the surrounding environment. The foundation part has also been precast, achieving both larger size and labor-saving efficiency. Additionally, it can be used for riverbank protection and road retaining walls, allowing for the habitation of plants and microorganisms in rivers, while also providing sound absorption effects on land. 【Features】 ■ The block length is 35 cm, and it can accommodate slopes from 1:0.3 to gentle slopes. ■ Improved workability - Two blocks can be easily installed by machine for every 1.0 m². *For more details, please download the PDF or contact us.

• Earth retaining wall/foundation reinforcement

This product is a central divider that creates a boundary on sidewalks while preventing the growth of weeds. Conventional products allowed grass roots to grow freely, but this product interlocks concrete precast products with asphalt and concrete, eliminating gaps and making it difficult for weeds to grow. By eliminating weeds, the landscape improves, and it also leads to a reduction in mowing costs. 【Features】 ■ Protrusions inhibit grass growth ■ Enhances the landscape ■ Reduces mowing costs related to maintenance ■ Same workability as conventional products *For more details, please refer to the catalog or feel free to contact us.
