"Super Doma" is a groundbreaking construction method that supports floor concrete with a frame-type improved wall. It allows for easy adjustments to floor loads, including changes in building usage, rearrangement of materials, and additions. Furthermore, it can support regardless of the depth of weak ground. Since it is supported separately from the building foundation, it provides a damping effect during earthquakes. 【Features】 ■ Alternative method for structural slabs ■ Numerical verification through stress analysis ■ Can support floors regardless of the ground type *For more details, please refer to the PDF materials or feel free to contact us.

The "Super Cube" is a patented method by Rias that surrounds the ground with a frame-type improved wall to prevent lateral movement of soil and to prevent ground subsidence. The frame-type improved wall is constructed using the "MMB method (slurry additive block-type mixed treatment method)," which has obtained construction technology certification from the Japan Building Center. 【Features】 ■ Alternative method for surface ground improvement ■ Creates a homogeneous improved body using the MMB method ■ Allows for numerical analysis to confirm floor deformation and stress ■ Versatile applications such as preventing the tipping of pile drivers and cranes *For more details, please refer to the PDF materials or feel free to contact us.

"Land Guard" is fundamentally a structural countermeasure method that suppresses ground deformation by enclosing the building foundation ground in a frame shape with a continuous underground wall. It is suitable for soft ground measures, seismic retrofitting, and liquefaction countermeasures. Additionally, our company also offers "Multi Guard," a standalone method for soft ground measures. [Features] ■ Fundamentally a structural countermeasure method ■ Suppresses ground deformation by enclosing the building foundation ground in a frame shape with a continuous underground wall ■ Suitable for soft ground measures, seismic retrofitting, and liquefaction countermeasures *For more details, please refer to the external link page or feel free to contact us.

The "MMB Method (Multi-Mixing Bucket Method)" is a block mixing treatment method suitable for supporting buildings and structures, as well as for soft ground countermeasures using a slurry addition approach. It can be implemented on slopes and can accommodate changes in the depth of the supporting ground. It is applicable to independent foundations, strip foundations, and mat foundations. Additionally, with a dedicated management device, reliable construction management and highly dependable ground improvement can be achieved. 【Features】 ■ Applicable to a wide range of geological conditions including sandy soil, clayey soil, and loam ■ Ground improvement can be achieved up to a depth of 5 meters ■ The bearing capacity after improvement can reach approximately 300 kN/m² for the long term ■ The supporting ground and the mixing condition can be visually confirmed directly ■ Low vibration, low noise, and dust-free *For more details, please download the PDF or feel free to contact us.
