The "CR Slab Type II" is a technology for remodeling weathered or damaged drainage ditches. It has insert nuts embedded in the four corners, allowing for height adjustment of the product. It comes in three different lineups to accommodate various channel widths and wall thicknesses. Using non-shrink mortar to integrate the site-cast drainage ditch with the CR Slab Type II shortens the period until release. 【Features】 ■ Height adjustment of the product using adjustment bolts ■ Compatibility with channel widths and wall thicknesses ■ Integration of existing site-cast drainage ditches with the CR Slab Type II ■ Maintenance and management of drainage channels *For more details, please refer to the PDF document or feel free to contact us.

• Gutters and U-shaped gutters

The "Easy Grating Type II" is a technology for remodeling weathered or damaged cast-in-place gutters. The top part of the gutter is removed, and a grating with adjustable bolts is set in place and adjusted for height. Concrete is then poured around it to complete the process. It is suitable not only for road longitudinal sections but also for road cross sections and sidewalks. 【Features】 ■ Compatible with road longitudinal and transverse sections, as well as sidewalks ■ Remodeling of weathered or damaged gutters ■ Grating with adjusters *For more details, please refer to the PDF document or feel free to contact us.

• Gutters and U-shaped gutters

"WP" is a construction method that ensures the protrusions of the blocks fit tightly with the pavement, preventing the growth of stubborn weeds that thrive on roads. It can be installed using the same method as conventional techniques. It effectively prevents cracking and shifting of the pavement. It is resistant to temperature changes and vibrations, making it difficult for weeds to grow. 【Features】 ■ Improves the landscape of roads and enhances the environment ■ Contributes to a reduction in traffic accidents ■ Reduces grass cutting costs ■ Installation of blocks is the same as conventional methods ■ Installation length has an overwhelming track record of several hundred kilometers *For more details, please refer to the PDF materials or feel free to contact us.

This technology involves removing only the weathered or damaged upper part of an existing cast-in-place drainage channel through cutting or chipping, and then placing a precast product called "CR Slab Type II" on top. It integrates the upper and lower parts with non-shrink mortar to remake the drainage channel. 【Features】 ■ Height adjustment of the product is possible with adjustable bolts ■ Compatible with channel widths of 200mm to 500mm ■ Integration with existing cast-in-place drainage channels ■ Maintenance and management of the drainage channel ■ NETIS registration CG-120034-A ■ Certified by the Tottori Prefecture New Technology and New Method Utilization System ME240928-46 *For more details, please refer to the PDF materials or feel free to contact us.

The "Weed Prevention Method WP" is a construction technique that strongly inhibits the growth of weeds proliferating on roads. The protrusions of the blocks interlock firmly with the pavement, making it difficult for them to separate even with temperature changes or vibrations, thus creating an environment unsuitable for plant growth. 【Features】 ■ Improved landscape and road environment ■ Contributes to a reduction in traffic accidents ■ Reduces grass cutting costs ■ Installation can extend for several hundred kilometers ■ Registered with NETIS *For more details, please refer to the external link or feel free to contact us.

The long-neglected and damaged drainage ditches not only create a rattling noise every time a vehicle passes but also pose a risk of pedestrians falling and getting injured, as well as detracting from the landscape. The "drainage ditch repair method" proposed by Nikkon involves leaving the undamaged lower part of the ditch intact while only repairing the damaged upper part. We introduce various types of "Easy Grating Type II" that accommodate T25 cross-section, standard mesh, and fine mesh loads, as well as the "CR Slab Type II" that integrates the upper and lower parts with non-shrink mortar, and the "CR Slab for Cross-Section" that collects water through a central grating. 【Features】 ● No need for complex formwork, leading to reduced construction time. ● The material for the receiving frame is high corrosion-resistant galvanized steel plate (ZAM), making it resistant to rust and highly durable. ● The length of the receiving frame is a four-sided frame of L2015, designed to accommodate two L995 main units. ● Height adjustment sections are provided at four points on the four-sided frame, allowing for fine height adjustments after installation using adjustment bolts. ● Adjacent receiving frames can be connected and integrated with bolts. ● The grating body is fixed with bolts. NETIS Registration Number: CG-170001-A *For more details, please refer to the catalog or feel free to contact us.
