FX permeable gutter and variable gutter
A structure that maximizes retention and infiltration capacity! It excels in maintenance management, functionality, and workability.
We handle "FX permeable gutters and adjustable gutters." The FX permeable gutter adopts a slit hole structure that does not get blocked by crushed stone. In construction work such as land development and parcel consolidation, as well as in large store parking lots, making these gutters permeable is essential for drainage improvement, allowing for significant design changes without compromising aesthetics while effectively controlling rainwater runoff. Permeable gutters can widely permeate relatively shallow ground, providing moisture to trees and being effective in preventing global warming. 【Features】 ■ Adopts a structure that does not hinder permeability ■ Resistant to clogging ■ Cost reduction ■ Excellent in maintenance management, functionality, and workability ■ The FX permeable gutter adopts a slit hole structure that does not get blocked by crushed stone *For more details, please refer to the PDF materials or feel free to contact us.

Slit gutter "Bicycle-friendly gutter"
A drainage system ideal for bicycle path development. Compliant with the "Guidelines for Creating a Safe and Comfortable Bicycle Use Environment."
The "bicycle-friendly gutter" is an optimal slit gutter for bicycle path development in accordance with the "Guidelines for Creating a Safe and Comfortable Bicycle Use Environment" presented by the Ministry of Land, Infrastructure, Transport and Tourism. The exposed width of the gutter is extremely narrow at 90mm, allowing for a wider paved area. Bicycles can travel on the asphalt pavement, making it safer compared to typical L-shaped street gutters (with an exposed width of 500mm and a cross slope of 6%). Additionally, like our "urban-type gutter," it can continuously collect water through the slits, eliminating the need for expensive grating. In terms of management, the gutter's cross-section is oval, which increases the flow velocity during low flow conditions, preventing sediment accumulation and reducing cleaning costs. We have posted a video of the bicycle-friendly gutter on the construction technology and method video site of Kentsu Shimbun. By watching it, you can earn CPDS/CPD credits. https://cpds.kentsu.co.jp/technology/detail?id=115 *For more details, please refer to the PDF materials or feel free to contact us.
