This is a circular drainage channel that demonstrates the drainage function of permeable pavement. It features a design structure with optimal drainage capabilities based on rainfall experiments. The inlet structure pursues the thinning of the permeable pavement layer at the collection area of the circular drainage channel. The circular drainage channels are strongly connected to each other with bolts. It is a design structure that comes as a set with the circular drainage channel and a dedicated catch basin.

By stacking the plastic rainwater storage material "Sun Geocube" and surrounding it with a waterproof sheet (or permeable sheet), a highly voided underground rainwater storage tank is formed. By combining sheets, it is possible to construct three types of systems. 【Basic Structure】 1. Storage System → By laying a waterproof sheet on the bottom and walls, rainwater can be stored and slowly drained or utilized for water use. (The waterproof sheet is protected by a protective sheet.) 2. Infiltration System → By laying a permeable sheet on the bottom, ceiling, and walls, rainwater is temporarily stored. The rainwater gradually infiltrates into the soil through the permeable sheet. 3. Storage + Infiltration System → By making only the lower part of the structure a permanent storage type, a certain amount of stored water can be secured for utilization. Additionally, the upper part functions as a storage facility. *For more details, please download the PDF or contact us.

Traditionally, protective fences that have rusted and corroded have been discarded and replaced with newly manufactured ones. However, the "Reuse Handrail" proposed by Soil Industry Co., Ltd. can transform existing handrail materials into like-new condition through surface treatment, without the need to manufacture new protective fences. This not only provides the same corrosion resistance as new ones but also allows for improved aesthetics through painting treatment. By reusing existing handrails, we can achieve CO2 reduction and lower lifecycle costs, enabling the maintenance of safe and comfortable bridge protective fences.

FabriForm, which uses high-strength synthetic fibers and is also known as fabric formwork and concrete mat method, is a technique where concrete is injected into factory-made FabriForm mats based on design drawings and allowed to cure on-site. Compared to traditional cast-in-place concrete and the laying of precast blocks, it enables construction with fewer personnel and in a shorter time frame. Since underwater construction is possible, it eliminates the need for switching work and water-stopping work, resulting in shortened construction periods and enhanced economic efficiency. It adapts well to complex slopes with varying gradients, achieving a uniform thickness. Due to pressure injection by pumps, it can cover a wide area at once, regardless of slopes or flat areas. The FabriForm mats are lightweight, allowing for safe construction and easy transportation and storage. The water-cement ratio is significantly reduced, leading to particularly high initial strength and a shortened curing period. We offer a wide range of options tailored to usage conditions, including filter point type, no-filter type, and greening type. For more details, please contact us or refer to our catalog.

Bentfix is a waterproofing material made from natural clay bentonite (Na type) in sheet form. Due to its flexibility and durability, it is now used worldwide for leak prevention and greening in park ponds, biotopes, reservoir ponds, and river embankments, as well as in various fields such as waterproofing for waste disposal sites, capping, contaminated soil measures, and waterproofing for underground structures. In 1994, it obtained ISO 9001 certification, making it a highly reliable natural waterproofing material internationally.

The FD drain, which serves as a curb and drainage channel for bridges, features a double safety structure that prevents the cover from bouncing up and scattering. The underlying SG (melted zinc-aluminum alloy) coating has several times the corrosion resistance of standard hot-dip galvanized coatings, providing excellent rust prevention. Additionally, it has superior adhesion to various types of paint, ensuring that there is no concern about peeling over time. The nylon 12 coating maintains an average thickness of over 300μm, effectively blocking moisture from the iron substrate and underlying coating, thus achieving a long lifespan. Its excellent wear resistance means that even in harsh environments like road shoulders, it is less likely to chip or peel. For more details, please contact us or refer to the catalog.

GeoWeb adapts to any site environment with a short construction period and easy installation. It is a geocell product made from high-density polyethylene (HDPE) sheets that are continuously bonded into a three-dimensional honeycomb shape using high frequency. By filling the cell structure with filler material, it becomes a strong structure. Additionally, it is lightweight and flexible, making installation easy, and it is effective for various applications such as slope protection, riverbank reinforcement, and improving the bearing capacity of roadbeds.

The "Waters" automatic flushing toilet is a clean and hygienic self-contained toilet. As long as there is power, it can provide a sanitary flushing toilet even in areas without a sewage system. Unlike conventional toilets that use a combined septic tank, it is self-contained and does not require a discharge point for treated water. Therefore, it has an extremely low impact on the surrounding environment and does not require application to local governments for installation. The bio-type septic tank "Bain System" equipped in Waters was developed as a toilet for the Japan Ground Self-Defense Force's field training sites and has been introduced to military bases nationwide as a procurement item by the Ministry of Defense since fiscal year 1992. Its durability for continuous use by large numbers of people has been proven during the Great Hanshin-Awaji Earthquake and the Winter Nagano Olympics. Since fiscal year 2001, it has also been recognized as a product for improving the image of construction sites by the Ministry of Land, Infrastructure, Transport and Tourism, contributing to the improvement of labor environments. Because "Waters" is a self-contained unit, it is easy to install and can be relocated after installation. It is effective for installation in riverbeds where relocation is anticipated and in disaster response bases, among other locations.

The "Smart Drain E-100 Type" is a steel side ditch that maintains a constant slope, ensuring safety. By having a consistent cross slope, the need for a street apron is eliminated, allowing for a 40 cm increase in the width of the roadway and sidewalk. Additionally, despite its lightweight and compact structure, its water flow capacity is approximately twice that of conventional L-shaped street ditches. 【Features】 ■ Improved safety ■ Increased road width ■ Approximately double the water flow capacity ■ Lightweight and strong compact design ■ Cost-effective *For more details, please refer to the PDF or feel free to contact us.

The steel side ditch for shoulder drainage, Smart Drain, ensures safety and allows for road width expansion. It also excels in water flow capacity and features a compact and space-saving design. Smart Drain is available in three types: S-type, E-type, and C-type, which can be selected according to the shape of the road. It can eliminate puddles on sidewalks and shoulders, allowing for manual installation with minimal excavation. This significantly shortens construction time and minimizes the impact on the surrounding area. For more details, please contact us or refer to the catalog.
