I want to quickly repair the damaged drainage ditch! I want to shorten the construction period and fix the ditch cheaply in one day! If you're struggling with drainage repairs, this is a must-see! We will solve your problems with the "Neplus Method"!
Road damage has been increasing year by year due to the rise in vehicle traffic. Among these, damage to the upper part of roadside ditches has worsened the living environment for local residents due to accidents caused by uneven surfaces, as well as noise and vibrations during vehicle passage. The Neplus method is an environmentally friendly new technology that offers numerous benefits such as cost reduction, resource and energy savings, and shortened construction periods. It has been adopted in various locations including expressways, national roads, and prefectural and municipal roads. 【Slit Type Construction Example】 Restoration of ditches with uneven surfaces to a flat condition. → The work is completed in one day, ensuring peace of mind for delivery locations. 【Bolt Fixed Type Construction Example】 Construction is possible in areas where long-term traffic restrictions cannot be implemented. → The height adjustment feature allows for alignment with cross slopes. *For more details, please contact us or download the PDF materials for review.
