Commercializing optimal drainage structures based on experimental data from industry, government, and academia. A circular waterway that maximizes the functionality of drainage pavement.

【Features】 ○ Improved traffic safety ○ Barrier-free compatibility ○ Drainage holes adjusted to pavement surface thickness ○ Technology based on joint experiments between industry, academia, and government ● For more details, please download the catalog or contact us.

Based on the consensus of member companies nationwide, the waterway developed by the association, incorporating the know-how accumulated over the past 30 years, has become the "Unified Circular Waterway."

【Lineup】 ■ Type I ・Standard type ・Barrier-free type ・Type V, cross type ■ Type II ■ Type III ■ Type IV ■ Type V ■ Urban type *Available in areas excluding the Kinki region. ● For more details, please download the catalog or contact us.

It has a double safety structure to prevent the lid from popping up and scattering.

【Features】 ○ Double safety structure to prevent the lid from flipping up and scattering → Lid flipping prevention mechanism → Scattering prevention by chain ○ Surface treatment can be selected according to environmental conditions → SG plating + nylon coating Exhibits excellent corrosion resistance and outstanding rust prevention even in harsh environments → Nylon 12 coating Ensures an average film thickness of over 300μm, achieving long lifespan → Hot-dip galvanizing Maintains minimum rust prevention at a low cost ○ NETIS registration number: CB-060010-A 【Product Lineup】 ○ Florida type ○ Flat type ○ Block type ○ Mountable type ○ Expandable section / Flow pipe ● For more details, please contact us or refer to the catalog.

We will introduce examples of smart drains installed in roads, sidewalks, parking lots, and parks.

【Features】 ○ Ensures safety and allows for road width expansion ○ Excellent water flow capacity ○ Compact and space-saving design ○ Eliminates puddles on sidewalks and shoulders ○ Manual construction possible with minimal excavation area ○ Significant reduction in construction time, with minimal impact on the surrounding area ○ Three types available to match the road shape: S type, E type, and C type ● For more details, please contact us or refer to the catalog.

Simple structure and high durability. Steel side ditches with a reduced cross-section design.

【Lineup】 (Excerpt) ○ Type C → Available in types compatible with permeable pavement (drainage pavement) and for management inspection → Cost reduction achieved through smaller cross-section → Lightweight design allows for easy installation → Strength meets the reliable T-25 specification (for longitudinal use) → Effectively collects surface drainage in limited installation cross-sections ○ Type S → Available in types compatible with drainage pavement and for management inspection → Slit structure minimizes impact on landscape while achieving smaller cross-section → A truly multifunctional gutter that integrates drainage capacity, aesthetics, and ease of installation ● For more details, please download the catalog or contact us.

There are no gradient breaks, and the safety of the road shoulder is improved! The water flow capacity is about twice that of the conventional L-shaped drainage channel.

【Other Features】 ■ No height difference at the boundary between the pavement and the street drainage apron ■ Quickly drains rainwater from the slit drainage channel ■ Eliminates puddles, creating a comfortable road without splashing ■ Reduces excavation volume, leading to shorter construction periods ■ Can use general-purpose blocks, making repairs and replacements easy ■ Small but strong T-25 design ■ Large water flow even with a small cross-section, improving cost-effectiveness *For more details, please refer to the catalog or feel free to contact us.

12% cost reduction compared to conventional methods! Achieving a large-capacity and reliable wide collection slit!

【Features】 ○ Revolutionary water collection structure → The newly developed "comb-shaped interlocking structure" enables a large capacity and reliable wide water collection slit. ○ Easy maintenance management → The upper and lower split structure allows for quick adaptation to sudden planning changes. Replacement during damage can be handled by simply exchanging the upper part. ○ Abundant variations → Utilizing the advantages of the split structure, we offer a wide range of variations. We can also accommodate region-specific specifications upon request. ○ Variable slope compatibility → By using a deep-type lower section, it is possible to change the road slope and the water flow slope within the channel, enabling "variable slope compatibility." ○ Achieving low cost → Our unique shape, which does not use extra parts and employs a pouring method, has achieved overwhelming low costs compared to conventional methods. The uneven shape serves as a guide during construction, allowing for quick and accurate installation. For more details, please download the catalog or contact us.
