The "Multi Slit Gutter" is a road product handled by Kitamura Concrete Industry. It does not require a hollow type like pipes or circular water channels, and by simply increasing the number of cover molds, it can offer many variations, reducing mold costs and improving productivity. Additionally, a cost-effective Type II gutter has been standardized, following the JIS design as a dedicated cross-section gutter, allowing for the construction of slit gutters at a low price. It meets various site needs with multiple functions such as free slope, drainage pavement, barrier-free compliance, prevention of cover rattling, and prevention of grating protrusion. 【Features】 ■ Achieves low cost ■ Functional to accommodate various situations ■ 7 variations compatible with T-25 vertical and horizontal cross-sections ■ Ministry of Land, Infrastructure, Transport and Tourism NETIS registration number: KK-980098 (technology with expired NETIS listing period) ■ New technology organization number by the Japan Highway Public Corporation: 200200002 *For more details, please refer to the PDF materials or feel free to contact us.

• Concrete sheet piles and piles

To respond to flooding caused by guerrilla rainstorms and concentrated heavy rains, we have installed drainage holes in the green stone section to enhance drainage performance. The crown cover minimizes the inflow of fallen leaves and debris. Additionally, by replacing only the damaged upper parts, we shorten the construction period, reduce waste, and use fewer materials through the "Neplus method (drainage repair)," which also accommodates special and integrated drainage systems. The universal design grating prevents bicycle wheels from getting stuck or falling in, supporting safe riding. 【Features】 ■ L-shaped drainage systems that prevent road surface flooding from typhoons and guerrilla rainstorms ■ Enhanced drainage performance of the L-shaped green stone section ■ Compatible with the Neplus method (drainage repair) ■ Supports safe cycling "Crown Support" is a product that combines L-shaped rainwater drainage systems and street drainage systems made of concrete secondary products with universal design grating for bicycle path measures. It can also be constructed using the Neplus method for drainage repair work. *For more details, please refer to the PDF materials or feel free to contact us.

• Road construction

The "Neplus Method" is a revolutionary drainage repair technique that only replaces the damaged upper part of the drainage channel. Since the lower part can be used as is, it reduces construction waste by 80% compared to conventional methods. For construction lengths of 8 to 10 meters, the work can be completed in as little as one day! By reducing the number of work processes, significant cost savings on construction expenses are achieved. 【Features】 ■ Use of undamaged lower parts, reducing construction waste by 80% ■ No excavation required, no excess soil disposal! ■ Cutting from the inside of the drainage channel, no impact on nearby structures ■ No need for temporary drainage channels, reducing expenses ■ NETIS registration: HR-060021 *For more details, please download the catalog or contact us.

• Gutters and U-shaped gutters

The "Neplus Method" is an innovative drainage repair construction system that has been welcomed with great interest in the field of road maintenance, responding to the demands of the times. The development of the Neplus Method was a significant turning point, driven by the need to solve societal problems and challenges through technological advancement. There are various construction types available, including soundproof, slit, buried, and circular drainage options, allowing for the selection of the most suitable method for each construction site. 【Features】 ■ 80% reduction in construction waste compared to traditional methods ■ 100% reduction in excavated soil compared to traditional methods ■ Can be constructed even when structures are close together ■ Immediate traffic reopening for resident peace of mind ■ Significant reduction in construction costs ■ No need for temporary drainage, resulting in cost savings *For more details, please refer to the PDF document or feel free to contact us.
