We will quickly replace the deteriorated drainage cover.

As a feature, the upper part of the drainage ditch is cut with a specialized horizontal cutting machine, and after removal, a new cover plate is installed to complete the process. We have numerous construction achievements in updating the aging cover plates of drainage ditches in front of stores, on sidewalks with heavy pedestrian traffic, and across roads. Our company provides construction proposals for each site to various municipalities, including the Ministry of Land, Infrastructure, Transport and Tourism, primarily in the three prefectures of Hokuriku.

Our company, based in Ishikawa Prefecture in the Hokuriku region, specializes in the W2R method, a waterway regeneration technology. We carry out the renewal of existing gutters, including maintenance and repair, lid replacement, and the development of barrier-free sidewalks. The low-noise W2R horizontal cutting machine (gutter horizontal cutting machine) operates very quietly and is environmentally friendly, significantly reducing construction time compared to conventional gutter maintenance and repair projects. Please feel free to contact us if you have any inquiries.
