At construction sites for "concrete work" such as roads, sewers, and waterways, there are numerous challenging issues such as cost reduction and shortening construction periods. Kitamura Concrete Industry, a specialized manufacturer of concrete products, offers a wide range of high-performance "concrete products" that help solve these challenges. In addition to the "Multi-Slit Side Ditch," which reduces formwork costs without the need for intermediate molds, there are many items available on-site to choose from, such as "manhole covers" and "assembly soil retaining walls." 【Here are some of our product lineup】 ◎ Multi-Slit Side Ditch ◎ Reinforced Concrete U-Shape ◎ Reinforced Concrete Side Ditch for Roads ◎ Round Manhole Slab ◎ Cover for Fence Beams ◎ Reinforced Concrete Assembly Soil Retaining Wall ◎ Rainwater Pit ◎ Floor Paving Blocks for Waterways ◎ T-Type Blocks, etc. Right now, we are offering a comprehensive catalog of over 200 pages for free! *Please download the digest version from the link below. *If you would like a printed copy, please feel free to contact us, and we will send it by mail.

We are offering a comprehensive catalog from our company, which handles a wide range of concrete secondary products! Among them, we highly recommend the "Multi-Slit Drain," which can be designed in an ideal type for side ditches. It does not require a hollow type like pipe channels or circular waterways; by simply increasing the number of lid forms, we can provide many variations to meet various site needs. Additionally, it accommodates both vertical and horizontal cross-use and free gradient ditches. It is especially suitable for places where landscape is a priority! Other products include road products, sewer products, manholes, and retaining wall products, among many others! 【Contents (excerpt)】 ■ Reinforced concrete U-shaped ditches (including JIS products) ■ Manholes for sewer systems ■ Assembled retaining walls ■ New ditches such as Multi-Slit Ditches, etc. *For more details, please download the catalog or contact us.

We will solve noise and dangerous slipping!

U-shaped gutters used in connection with roads, land, and drainage ditches. They conform to JIS standards.

Slim down the product, and the gray tin is fixed with bolts. The mound type can use boundary blocks that meet JIS standards.

The full-open slit structure improves drainage functionality. It eliminates mud accumulation on the surface of the gutter. The product is lightweight and reasonably priced.

The flat sides make compaction easier, eliminating shoulder drop in the pavement, and allowing for precise construction that fits perfectly with existing structures.

The cover is made of one piece, making it easy to install and economical.

Even when used on a central divider, the center line does not overlap with the product.

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.

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.

A side ditch used in connection with roads, land, and drainage channels.

The "Rain Collector" is a drainage facility created between the sidewalk and the roadway as a pipe to channel water discharged from permeable pavement that quickly absorbs rainwater. This product contributes to reducing car noise. The drainage holes are elongated, allowing water that has seeped into the base layer to be drained as well. The vertical grooves accommodate permeable pavement with a thickness of 25 to 30 mm. By efficiently draining water within the pavement, it helps improve the durability of the pavement. 【Features】 ■ Elongated drainage holes ■ Drains water that has seeped into the base layer ■ Accommodates permeable pavement with a thickness of 25 to 30 mm ■ Helps improve pavement durability *For more details, please refer to the PDF document or feel free to contact us.

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.
