The TerraArmée method, invented in France 40 years ago, is a technique that allows for the vertical and high construction of embankments. By laying ribbed strips (band-shaped steel reinforcement) within the embankment and covering the surface with concrete skin (modular wall panels), it enables the creation of vertical and high retaining walls. This method is referred to as reinforced earth because it reinforces the soil with strips, and its principles have become the foundation for many existing techniques. Backed by years of know-how and reliability, the TerraArmée method is the most proven technique both globally and in Japan.

The Super Tail Arm Method is a next-generation tail arm construction method developed to reduce construction costs, improve workability, and enhance aesthetics in urban areas.

The Tail Arm Method, which has accumulated a wealth of experience over 25 years in a wide range of applications, demonstrates numerous excellent advantages as a Tail Arm retaining wall in land development.

The greening tail arm method, as its name suggests, is designed to allow for the greening of the surface of tail arm embankments. The basic principle of the method is the same as that of the tail arm method, but instead of using heavy concrete skins, it employs mesh panels and vegetation mats, making it even easier to construct. The greened embankment surface harmonizes with the surrounding environment in suburban and mountainous areas.

"TerraArm" is a reinforced soil wall construction method that has been officially certified for partial repair methods of wall materials in the "Reinforced Soil Wall Design and Construction Manual" published by the Civil Engineering Research Center. Traditionally, core sampling was essential for evaluating the integrity of reinforced soil, making the pull-out testing process cumbersome. However, with KD panels and TerraArm FS, simplified inspections are now possible. This allows for early detection of deterioration within the TerraArm and enables understanding of the internal conditions of the wall. It has demonstrated high seismic resistance even in areas affected by strong earthquakes such as the Tohoku Pacific Offshore Earthquake, the Niigata Chuetsu Earthquake, and the Southern Hyogo Earthquake. [Features] ■ Easy removal of wall materials and reinforcements ■ Possible repair work in small spaces ■ Ability to confirm integrity after use ■ Easier maintenance management *For more details, please refer to the PDF document or feel free to contact us.

Do you have any of the following concerns? ■ I want to know the features and application examples of the reinforced soil wall method concisely. ■ I want to explain the method overview to a newcomer, but I don't have the materials or time for training. We have created materials that can solve these concerns. The materials are available for free, so please feel free to share and use them within your company. 【Table of Contents】 "Introduction to Reinforced Soil Wall Method" 1: What is Reinforced Soil? 2: Scope of Application and Features of Reinforced Soil Walls 3: Types and Design of Reinforced Soil Walls 4: Case Studies of Reinforced Soil Walls *For more details, please download the PDF or feel free to contact us.

The case study collection introduces various examples. ■ How to address subgrade measures (soft ground, sliding measures, high embankments) ■ Construction challenges (ancillary work, proximity to obstacles, temporary structures) ■ What kind of structures should be built near water bodies, such as revetments (super levees, salt damage measures) ■ Can it be used in land development (consideration for landscape and residential construction regulations) 【Table of Contents (Partial)】 "Tail Arm Method Case Study Collection" 01 Land Development 02 Landscape Design 03 Greening 04 Subgrade Measures and Arc Sliding Measures 05 High Walls and Multi-layered Stacking *For more details, please download the PDF or feel free to contact us.

We would like to introduce our proposed riverbank protection tail arm method, "Aqua Tail 35." It ensures the durability of the wall panel against flowing water. It conforms to the structural model "stacking model" equivalent to large blocks in the "Ministry of Land, Infrastructure, Transport and Tourism River Erosion Control Technical Standards" and "Mechanical Design Method for Riverbanks." By using crushed stone as fill material below the river water level, it responds to rapid changes in water levels. 【Features】 ■ Ensures the durability of the wall panel ■ Adaptable to areas prone to salt damage ■ Achieves significant cost reduction and shortened construction time ■ Confirms safety during flooding ■ High stability during construction *For more details, please download the PDF or feel free to contact us.
