"Compass" is a vibration-damping joint fitting that protects homes from various vibrations. The rubber part absorbs seismic energy. Major damage or collapse of buildings is largely caused by the failure of joints in columns and beams, but this product does not experience issues such as screws coming loose, even during significant earthquakes. Additionally, it can be installed without protruding from columns or beams, eliminating the need to create new walls. Therefore, it allows for ample openings, such as windows. [Features] - Reduces building sway caused by earthquakes and prevents collapse - Reduces vibrations that occur in daily life - Does not interfere with design - Can be installed under various conditions - Easy to install, suitable for both new constructions and existing buildings *For more details, please refer to the PDF document or feel free to contact us.

"Expanded Polystyrene Particle Lightweight Concrete" has moderate fluidity and can be poured into free shapes. It is possible to design a mix that has underwater non-segregation properties. Unlike lightweight mixed soil, EPS lightweight materials, concrete materials, and natural ground materials, it is a uniform ground material that can be adjusted to appropriate unit weight and strength, making it effective in reducing ground consolidation settlement. [Features] ■ It is possible to design a mix with underwater non-segregation properties. ■ It has moderate fluidity and can be poured into free shapes. ■ It is possible to design to reduce slip failure stress. ■ Bagging improves workability and shortens construction time. *For more details, please refer to the PDF document or feel free to contact us.

The "Expanded Polystyrene Light Drain Civil Engineering Method" is a disaster recovery and disaster prevention technology that enhances performance and effectiveness by adding drainage functionality to a modified structure built with expanded polystyrene blocks. As a result, it offers higher workability, performance, and effectiveness compared to other drainage materials. Additionally, since the construction is done manually, there is no need for specialized workers or special machinery. 【Features】 ■ Adds drainage functionality to a modified structure built with expanded polystyrene blocks ■ Higher workability, performance, and effectiveness than other drainage materials ■ Pre-cut products delivered to the site from an expanded polystyrene molding factory ■ No need for specialized workers or special machinery as the construction is done manually *For more details, please refer to the PDF document or feel free to contact us.

The "Light Drain Columbus Method" uses EPS in a shape developed by our company, laid under the foundation and floor slab. By placing a thick layer of EPS (air layer) between the foundation concrete and the ground, it cuts off the edges and reduces vibrations (horizontal and vertical) from the ground. This prevents resonance in vibrating buildings and minimizes the energy of the vibrations. Additionally, during disasters or prolonged power outages without heating or cooling, it effectively utilizes natural energy, allowing for comfortable living without strain. 【Features】 ■ Utilizes natural energy ■ Enhances the durability of the foundation (floor slab) ■ Protects buildings from the ground during frequent earthquakes ■ Minimal temperature difference between the underfloor and indoor spaces ■ Allows for integrated use of underfloor and indoor spaces *For more details, please refer to the PDF materials or feel free to contact us.

"Light Filter" is a drainage material used in construction that requires backfill drainage materials, serving as a substitute for backfill gravel. It is lightweight yet has self-supporting properties (plate-like) and high compressive strength. Additionally, when it needs to be removed, it has excellent recycling characteristics, allowing it to be reused in plastic products, fuel, power generation, and more. 【Features】 ■ Reduces initial costs ■ Shortens construction time ■ Lightweight yet self-supporting (plate-like) with high compressive strength ■ Large voids (void ratio: approximately 30%) ■ Provides cushioning equivalent to or greater than EPS, contributing to improved seismic and vibration resistance of structures *For more details, please refer to the PDF materials or feel free to contact us.

"Light Drain Columbus" is a ground replacement method that was born from a shift in thinking to replace the surface ground with lightweight materials, thereby reducing the burden on the ground. Please consider this method in cases where the depth of the soft layer is deep, making piling costs excessively high, or in "soft ground" where cement-based improvements are difficult, as well as in "narrow sites" where the entry of large machinery such as pile drivers is challenging. 【Consider this method in the following situations (partial list)】 ■ Soft ground ■ Transition from pile foundations to direct foundations ■ Liquefaction ■ Archaeological designated areas ■ Earthquakes *For more details, please refer to the PDF materials or feel free to contact us.

"Magellan" has been developed not only to protect steel and wooden structures from earthquake damage (such as severe destruction or collapse) but also to minimize damage to non-structural components, serving as a multifunctional disaster mitigation reinforcement material that excels in property preservation and corporate business planning. We offer two installation methods: the "brace type" for use at column-beam joints and the "strut type" for openings and walls. It enhances structural strength, absorbs energy, suppresses interlayer displacement, and reduces the anxiety of shaking. [Features] ■ Effective for seismic resistance and vibration control ■ Installation methods include brace type and strut type ■ Maintenance-free ■ Applicable to over 90% of the floor area of steel buildings ■ Lightweight and cost-effective *For more details, please refer to the PDF materials or feel free to contact us.
