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.

The "Corrosion Doctor" is an ultrasonic diagnostic device that qualitatively and easily examines the extent of corrosion damage at the pavement boundary (around GL-40mm) of road accessories (such as steel signposts and lighting poles). Using SH wave transducers and analysis software, it can diagnose whether the condition is corroded or sound without excavating the pavement boundary. Please feel free to contact us if you have any inquiries. 【Detailed Information】 ■ Application Range - Poles with a diameter of 100mm or more - Pole embedment depth up to GL-900mm (base plate type, embedded type) - Asphalt pavement, concrete foundation, interlocking pavement, underground, etc. ■ Outside Application Range - Cases where the pole itself is strongly constrained by embedded concrete, making the embedment depth unclear, or where there is significant acoustic noise - Poles with a diameter of 100mm or less - Bent poles due to external forces *For more details, please download the PDF or contact us.

The "GR-U" is made of ductile cast iron, the same material as manhole covers. Its load-bearing performance complies with T-25 based on the Road Bridge Design Guidelines, ensuring that it does not suffer from damage or deformation even in harsh road environments where large vehicles frequently pass, preventing any rattling. Additionally, the surface's anti-slip structure reduces the risk of slipping. 【Features】 ■ Stable drainage performance ■ Slip prevention ■ Prevention of entrapment ■ Clogging prevention ■ Prevention of rattling and scattering due to steep slope support structure, etc. *For more details, please download the PDF or contact us.
