The "Tail Alme FS" is a construction method that allows for the safe visualization of abnormalities within embankments through fail-safe and fail-sensor functions, moving beyond the previous approach of determining abnormalities based solely on surface information. The "fail-safe function" ensures that if the function of the targeted component is lost, a separate component that is not active during normal conditions will take over, preventing any impact on the reinforced soil wall. The "fail-sensor function" visualizes abnormalities within the Tail Alme embankment. 【Features】 ■ Technology aligned with the basic plan for infrastructure longevity promoted by the Ministry of Land, Infrastructure, Transport and Tourism (H25) ■ Received the Excellence Award at the 3rd Infrastructure Maintenance Awards ■ Among similar maintenance management technologies, it has a simple structure that does not require power sources ■ Construction and durability are comparable to standard Tail Alme systems *For more details, please refer to the PDF document or feel free to contact us.

The "Taille Armée" is a technology that stabilizes soil particles through the friction of strips (strip steel) and retains the soil with a skin (wall material), forming a vertical and stable wall surface. Unlike gravity retaining walls, it does not suppress the soil but utilizes the flexibility of the soil, making it a flexible structure that is resistant to earthquakes and suitable for the natural conditions of our disaster-prone country. This technology can be applied across various fields such as architecture, civil engineering, and landscaping, enabling flexible designs that align with the specific plans and designs of various facilities in Japan. 【Features】 - It is the only reinforced soil wall that has obtained ministerial certification as a "Taille Armée retaining wall," allowing its use in highly important areas such as residential land development. - Being a vertical retaining wall, it maximizes the effective use of residential land. - Unique "free linear expression" characteristic of Taille Armée. - By flexibly responding to the choice of materials and colors for the skin and adding expressions, it harmonizes with the surrounding landscape. *For more details, please refer to the PDF materials or feel free to contact us.

"TerraVeil" uses mesh panels as wall materials in the tail-arm method, allowing for greening of the walls when combined with vegetation mats. With a simple component structure, it is possible to construct green reinforced soil at a low cost. The wall materials are made of lightweight reinforced mesh, enabling manual construction without the need for special techniques. By incorporating a sliding function of about 100mm during the assembly of the mesh panels, it can adapt to the deformation of the embankment. By restricting the connection points of the reinforcement materials and wall materials to four, it suppresses the protrusion of the wall and ensures the quality of the wall's finish. [Features] ■ Easy and economical construction ■ Flexibility that matches the characteristics of reinforced soil walls ■ Reliability that can be achieved because it is a tail-arm method ■ Creation of spaces that blend naturally into the landscape *For more details, please refer to the PDF document or feel free to contact us.

The "Terra Armé Method" is a reinforced soil wall construction method with a proven track record worldwide, developed in 1963 and implemented globally. Our company is developing new construction methods based on the principles and concepts of the Terra Armé Method. These new methods are registered in the Ministry of Land, Infrastructure, Transport and Tourism's information provision system for the utilization of new technologies (NETIS) and are being utilized as valuable new technologies. We promise to continue evolving in a more efficient and robust manner according to various environments, contributing to the creation of a better future for humanity. 【Features】 ■ Strong against disasters due to its resilient structure ■ Easy to construct with a simple component configuration ■ Versatility to accommodate various applications ■ Easy detection of anomalies due to its flexible structure *For more details, please refer to the PDF materials or feel free to contact us.

"Aqua Tail 35・14" is a reinforced soil wall construction method developed for river and bank structures, based on the reliability of the tail arm method, which boasts the highest track record in Japan. For areas affected by river water levels, we use "Aqua Tail 35" with a wall thickness of 350mm, ensuring high durability against collisions and wear from floating debris. Additionally, in areas not affected by water levels, we combine it with "Aqua Tail 14," which has a wall thickness of 140mm, achieving an economical structure while maintaining a sense of unity in the landscape. Moreover, by adopting precast concrete panels, we can reduce labor and shorten construction periods compared to cast-in-place retaining walls. The high permeability of the fill material and the wall structure allow for rapid response to sudden water level fluctuations, and safety has been confirmed through various tests and analyses. This reinforced soil wall construction method is suitable for waterfront environments, achieving shortened construction periods and cost reductions while maintaining high reliability. 【Features】 ■ High stability against flowing water and applicability to salt damage areas ■ Confirmed high safety against collisions with floating debris ■ Sufficient impact resistance of wall panel materials ■ Use of highly permeable "coarse aggregate" for fill materials *For more details, please refer to the PDF materials or feel free to contact us.

【Tail Arme FS】Visualizing Deformation and Abnormal Loads of Reinforced Soil Walls - The failure sensor function allows for visual confirmation of deformations within the reinforced soil. - The long-hole structure enables a slide of about 20mm, allowing the wall surface to tilt functionally, making it possible to confirm abnormalities from the outside. - Achieved without electricity, through the improvement and addition of existing materials. Maintenance management can be done at a low cost. - Additional implementation is possible at a low cost even at sites where design has already been completed. - Can be utilized for determining the timing of detailed investigations of reinforced soil walls and for planning repair strategies. - Registered technology in NETIS (QS-170031-A) and awarded the Excellence Award at the 3rd Infrastructure Maintenance Awards. 【Steel Corrosion Detection Sensor】Visualizing the Progress of Corrosion in Steel Components such as Reinforcements - Used in conjunction with the KD panel of Tail Arme to monitor the progress of corrosion in reinforcements and to determine the timing for sample collection. - A corrosion detection sensor for underground steel materials utilizing plastic optical fibers. - When the reduction in thickness due to corrosion reaches a predetermined depth, corrosion is detected by light blockage. - Utilizes natural light, eliminating the need for battery replacement or wiring. - Can be judged visually, and no specialized measuring instruments are required. Remote monitoring is possible through combinations with photography or remote cameras. - Can also be used for corrosion management of other underground steel structures such as steel pipe piles and steel sheet piles.

The Tail Arme All-Precast method is a reinforced earth wall construction technique that has transformed the top and foundation sections, which were traditionally constructed using cast-in-place concrete, into precast products. It was registered with NETIS (KT-210058-A) in October 2021, contributing to improved construction efficiency and quality. By combining a long-neck skin for the top section, precast foundation concrete, and precast cap concrete, it significantly reduces the need for formwork work, concrete placement, and curing time on-site. This leads to shortened construction periods, increased productivity, and enhanced safety, making it suitable for sites facing labor shortages or challenging construction conditions. Its adoption is also expanding in locations where traditional methods struggle with process management, such as cold regions and tiered sections. It represents a next-generation Tail Arme method aimed at balancing labor reduction and construction quality.
