It demonstrates its power even in sudden guerrilla downpours. Even when leaves and debris accumulate, it maintains drainage performance to solve road flooding!

"Kansuke" is a product that combines L-shaped drainage channels for fallen leaves and flood prevention with universal design grating for bicycles. It can also be installed using the Neplus method for repairing roadside ditches. Even if clogging occurs on the grating, drainage is maintained through the drainage holes on the vertical sections. **Features of Kansuke** - **Enhanced drainage performance at the L-shaped channel curb!** To address flooding caused by sudden heavy rain or concentrated downpours, drainage holes have been added to the curb section to improve drainage performance. This prevents flooding even when there are obstacles like fallen leaves or newspapers and magazines that could hinder drainage, thanks to stable drainage performance. - **Compatible with the Neplus method (drain cover repair)** The Neplus method, which has brought innovation to roadside ditch repair work, allows for the replacement of only the damaged parts, shortening construction time, reducing waste, and requiring fewer materials, making it a groundbreaking method. - **Supports safe cycling** By changing the shape of the grating to a triangular pitch, it prevents wheels from getting stuck or falling in. Additionally, the incorporation of anti-slip protrusions in the components has improved slip resistance. *For more details, please contact us or download the PDF materials for further information.*

The Neplus Method National Association is an organization that promotes the expansion of the "Neplus Method" for the repair of the upper part of drainage ditches, provides technical support, manufactures and supplies products, and offers technical assistance to construction partners. The Neplus Method involves removing only the damaged upper part of the drainage ditch with a specialized cutting machine and installing new repair products to renew the ditch. The construction period is quick, allowing for immediate traffic reopening if about 10 meters are completed in a day. Additionally, it can be easily implemented even in ditches close to structures or underground installations without the need for excavation. We have handled numerous drainage repair projects to date. If you have any issues with drainage work, please feel free to contact us.
