The "Disaster Prevention Wall Method" is a hybrid retaining wall with a tandem structure. To effectively utilize 100% of the backfill gravel as self-weight, the thickness of the retaining wall is reduced, significantly decreasing the excavation width and volume of excavated soil. Additionally, each tier of the back blocks has drainage and collection functions, allowing any groundwater that emerges from any part of the slope to be drained to the front of the wall, making it a "groundwater discharge type retaining wall." It has also been developed to meet other criteria such as integration through cast-in-place concrete and safe emergency construction responses. 【Features】 ■ Cost-reducing method ■ Groundwater discharge type retaining wall with high drainage functionality ■ Strongly integrated retaining wall ■ Enables safe emergency construction ■ Reduces complaints about backfill gravel settling *For more details, please download the PDF or feel free to contact us.

• Special Construction Method

The "Toris Method" is a system that involves creating holes in newly constructed vertical precast concrete retaining walls and setting "soil column blocks" that can be used for nesting on the back side, thereby supporting breeding. The main target birds are the "kingfisher" and the "dipper." By using soil column blocks manufactured in a quality-controlled factory, there is no need to check the materials for the nesting area or manage the construction, as the nesting area is secured simply by installation. Additionally, since the surface is concrete, there is no erosion from rainwater like on a cliff with exposed soil, allowing the nesting function to be maintained for a long time. 【Products Offered】 ■ Soil column blocks for kingfishers ■ Soil column blocks for dipper *For more details, please download the PDF or feel free to contact us.

• Special Construction Method

The "Eco Waterway Construction Method" consists of three types: bottom hole type, horizontal hole type, and combined type, which can be used according to the situation. The bottom hole type provides a habitat for bottom-dwelling organisms such as crabs and loaches by allowing sand and gravel or water to accumulate at the bottom of the waterway. The horizontal hole type creates a still water area, ensuring a habitat and refuge for juvenile and small freshwater fish. Additionally, the combined type incorporates both of the aforementioned types. The main body of the waterway uses conventional materials, making it economically feasible and easy to install a "multi-functional environmental waterway." 【Features】 ■ Direct use of conventional waterways that are 20cm deep ■ Entrance and exit secured with filler blocks ■ Ramp for small animals (soft slope) *For more details, please download the PDF or feel free to contact us.

This document introduces the "Weed Prevention Method and Weed Block." The "Weed Prevention Method and Weed Block" is a technology that has a "weed prevention function," which prevents the growth of weeds by eliminating gaps between concrete products such as pedestrian and roadway boundary blocks and pavement, allowing weeds to naturally wither. In Series 1, we explain the mechanism and features of the method, while Series 2 includes follow-up surveys and construction results. We present this information clearly using photographs. Please take a moment to read it. 【Contents】 ■ Series 1. Mechanism and Features of the Method - Explanation of the "three major mechanisms" that prevent weed growth and cause them to wither - Features of the "Weed Prevention Method" and Weed Block ■ Series 2. Follow-up Surveys and Construction Results - Follow-up survey on the Weed Prevention Method and Weed Block (Part 1) - Follow-up survey on the Weed Prevention Method and Weed Block (Part 2) - Follow-up survey on the Weed Prevention Method and Weed Block (Part 3) - Follow-up survey on the Weed Prevention Method and Weed Block (Part 4) *For more details, please refer to the PDF document or feel free to contact us.

• Civil Engineering Method

The "Wide Wall Method" is a cost-reduction construction technique that allows for the easy completion of sidewalk, roadway, and residential land widening simultaneously with the installation of large block masonry, significantly reducing total costs. By adding a vertical wall in front of the conventional cantilevered retaining wall, this innovative method enables the widening of shoulders and land above the retaining wall without significantly altering traditional methods. Additionally, by using it in residential areas, it allows for the construction of retaining walls with vertical faces at low cost without the need for L-shaped retaining walls. 【Features】 - The lower and front sections can use the "large block masonry" that has been traditionally used as is. - Reinforcement bars can be added as needed. - High safety is ensured. - Patent obtained.
