Steel side ditches that ensure drainage capacity in a limited installation cross-section.
The drain creator uses high-tensile steel for the beam members that support the load, allowing for a larger water flow cross-section. Even with a small cross-section, it has a significant drainage effect and load-bearing capacity, and its lightweight design enables efficient construction without heavy machinery. (T-25 design)
The running is different! By storing and infiltrating rainwater, it helps restore the natural cycle.
The box drainage system "Polacon All Weather" features sides made of Polacon, providing excellent permeability. By storing and infiltrating rainwater, it helps restore the natural cycle. The number of side drainage holes designed to accommodate permeable pavement has been increased, allowing for more uniform and efficient drainage. 【Features】 ■ The position of the side drainage holes can accommodate various pavement thicknesses. ■ To enhance the drainage capacity of the apron section, options for pavement drainage holes and grating-covered ditches are available. ■ The bottom of the pipe channel is shaped in an R design to ensure smooth water flow during low water levels, minimizing sediment accumulation even during prolonged dry weather. *For more details, please refer to the PDF document or feel free to contact us.
A circular water channel with continuous drainage ditches in the longitudinal direction.
It is a product that possesses five features: economic efficiency, functionality, high constructability, high quality, and beauty.
The twin side ditch has a high drainage capacity and is a buried type that is not exposed on the road surface.
【Shoulder Clarity】 【Bicycle Path, Bicycle Lane Compatibility】 The twin side ditches are equipped with continuous water conduits and drainage holes just below the surface of the permeable pavement, providing high drainage capacity by draining water within the permeable pavement layer downward. Additionally, the top surface of the side ditches is not exposed at the edge of the roadway, and the pavement surface uniformly continues up to the boundary blocks between the pedestrian and vehicle areas.
General-purpose pedestrian and vehicle boundary blocks are available! Narrow apron width pipe-type ditches.
The "Line Drainage Block - V Type 300" is a compact channel-type gutter that creates a safe and comfortable road space. It eliminates cross slope breaks, ensures flatness, and resolves steps and grooves that hinder passage. Additionally, the finely pitched independent slit design makes it difficult for bicycle tires entering at an angle to get stuck. 【Features】 ■ Improved safety for shoulder riding ■ Elimination of water puddles & suppression of water splashes ■ Compact with high workability ■ Reduction of traffic regulation area ■ Reduced risk of interference with underground installations *For more details, please refer to the PDF document or feel free to contact us.

Slope-compatible roadside drainage ditch that can be installed without gradient changes on roads with a slope.
The "FR (Free Rotation) Cross Drainage Ditch" is a drainage structure used at crossing points. Traditionally, ditches were constructed horizontally, resulting in changes in slope. However, by using this product, it allows for smooth vehicle movement across the crossing without any changes in slope, thereby improving safety. 【Features】 ■ Seamlessly accommodates the longitudinal slope of the road ■ Achieves smooth vehicle movement without changes in slope ■ Reduces the impact on the ditch during vehicle passage, thereby suppressing deterioration of the ditch and eliminating noise *For more details, please download the PDF or feel free to contact us.
Secure a wide shoulder width! The upper and lower split cassette type accommodates various sites.
"CS Sokkō" is a new type of slotted drainage developed based on our extensive track record of urban slotted drainage, adapted to the guidelines for creating bicycle-friendly environments. It features a narrow apron width and a wide shoulder width, ensuring that the grating of the management drainage section does not protrude into the roadway, thus not obstructing bicycle passage. Additionally, by simply changing the upper cassette (for longitudinal, transverse, or UD access) for a single lower drainage channel, it can accommodate various situations. 【Features】 ■ Split design ■ Ensures a wide shoulder width ■ Upper cassettes that can be selected based on site conditions ■ Secures a rich flow rate ■ Allows for the pouring of inverted concrete *For more details, please refer to the PDF document or feel free to contact us.
It is a circular drainage channel for road stormwater that has a small installation space and excellent economic efficiency.
The economy drainage channel "e-Suru" is a circular waterway for road rainwater drainage that enhances compact installation space and cost-effectiveness through the thinning and lightweight design of the product. There are three types: S-type for mounting, flat T-type for entry points, and R-type for entry points (buried specification). It is compatible with T-25 parallel loads for general vehicles. (It cannot be used for road crossings.) The catch basins and boundary blocks are specialized. 【Features】 ○ Box girder structure ○ Achieves thin and lightweight cross-section ○ Compact installation space and excellent cost-effectiveness ○ Dedicated boundary block installation requires no dry mortar and uses a bolt structure ○ NETIS registration number KK110014-A For more details, please contact us or download the catalog.
The soundproof structure of the lid and main body prevents rattling and suppresses noise!!
■The FX side ditch prevents rattling and suppresses noise by ensuring line contact between the curved surface of the main lid receiving part and the slope at the bottom of the lid. ■The FX side ditch has flat side surfaces, allowing for close construction to adjacent structures, enabling sufficient compaction, and preventing pavement settlement. ■Compared to conventional drop lid U-shaped side ditches, the FX side ditch is lighter and slimmer for both the ditch and the lid, allowing for smooth work during installation. ■The FX side ditch can be equipped with drainage filters for drainage products, making it compatible with permeable pavements. ■The FX side ditch offers a wide variety of components, not only for standard longitudinal use but also for "entrance/exit," "one-sided earth pressure," "corners," "sediment traps," and "manholes."
Hybrid structure of concrete, ductile, and steel grating!
The "Paybubble Series" is a hybrid cross-section and utility pole avoidance ditch that enhances the freedom of surface paving, improving the safety of snow removal operations and the workability of pavement replacement without changing the flow cross-section. By adopting ductile slabs, it ensures the same effective cross-section as the PU3 type ditch and the necessary pavement thickness for milling overlay work. We offer the underground type "Paybubble Cross Ditch," which considers road maintenance in snowy areas, and the "Paybubble Utility Pole Avoidance Ditch," which can effectively utilize narrow streets. 【Features of the Paybubble Method】 ■ Difficult to slip ■ Eliminates noise and cover damage ■ Road surface markings are possible ■ No grating damage ■ Safe snow removal operations *For more details, please refer to the PDF materials or feel free to contact us.
【Mud Prevention Measures】Collect rainwater that has seeped into the ground into the drainage ditch and discharge it to the drainage facility.
The "FVP Series" is a drainage channel designed to accommodate heavy vehicles. It can be used in various locations such as roads, parking lots for general and heavy vehicles, around buildings, and on grounds. With a rich lineup ranging from 300 to 1000mm in 100m increments, it can also accommodate variable slopes by pouring inverted concrete. It not only collects rainwater and surface water through the slits in the cover but also quickly drains rainwater that has permeated the ground from the sides (Polacon surface) into the channel and to the drainage facilities. 【Features】 ■ Structure designed for heavy vehicles ■ Accommodates variable slopes ■ Rich lineup ■ Prevents mud *For more details, please refer to the PDF document or feel free to contact us.
