Ground improvement work without using cement: Screw-Press method

Are you still satisfied with the conventional ground improvement methods using cement?

The implementation area is currently expanding sequentially, focusing on the Hokuriku and Kanto regions! The screw press method improves ground bearing capacity and achieves a "seismic-resistant ground." It creates a compaction phenomenon by pushing the surrounding soil with the volume of the screw itself, resulting in a stronger foundation. Since there is no generation of excavated soil, construction time is significantly reduced compared to conventional methods, allowing for low-cost construction. Additionally, there is no need for soil treatment that would become industrial waste, greatly contributing to environmental conservation. 【Features】 ○ Zero excavated soil ○ Significant reduction in construction time and costs ○ Environmentally friendly low-carbon ground improvement method ○ Pile formation using thinned wood or crushed stone is possible ○ Crushed stone piles are strong against earthquakes and significantly reduce liquefaction phenomena For more details, please contact us or download the catalog.

Liquefaction that struck the metropolitan area: Adding stability with 'ground improvement'!

Liquefaction that struck the metropolitan area: Adding stability with 'ground improvement'!

Introducing a method for artificially improving the ground without causing environmental pollution.

The Great East Japan Earthquake highlighted the damage caused by tsunamis, but the significant damage in the metropolitan area was due to "liquefaction." Liquefaction occurred not only in coastal reclaimed land but also in inland areas, affecting residential neighborhoods. This frightening liquefaction can be prevented in advance through our company's "ground improvement." "Ground improvement" refers to the construction work done to enhance the stability of the ground on which buildings are constructed, making it less susceptible to ground subsidence and differential settlement by artificially improving the ground. There are various methods for improving the foundation ground, including crushed stone pile method, surface improvement method, columnar improvement method, and steel pipe pile method. Our company recommends the "HySPEED method," which uses only natural crushed stone as a material, making it an environmentally friendly method. 【Features of the HySPEED Method】 ■ Strong against seismic shocks ■ Environmentally beneficial method ■ No waste disposal costs incurred ■ Contributes to the Earth through reuse ■ Liquefaction countermeasure method *For more details, please refer to the PDF materials or feel free to contact us.

Renewal method for existing gutters: 'W2R (Double Two R) Method'

Renewal method for existing gutters: 'W2R (Double Two R) Method'

It is a renewal method for existing gutters that excels in workability and is very environmentally friendly.

The "W2R Method" involves cutting unnecessary parts of existing drainage ditches from the inside using a specialized cutter called the "W2R Cutter," and then installing a precast concrete cover known as the "W2R Drain Cover" to renew the ditch. This method has very little impact on existing sidewalks, private properties, and surrounding residents, making it very environmentally friendly. The cutting surface of the W2R Cutter is smooth, and by installing the Pca cover after cutting, it enhances workability and reduces construction time. 【Features】 - Very environmentally friendly method - Excellent workability, reducing construction time - Can cut from the inside without damaging the ditch - Improves the three major issues of traditional methods (noise, dust, and debris) - The W2R Drain Cover excels in workability, walkability, and drainage performance For more details, please contact us or download the catalog.

Crack Detection Coating System for Concrete Structures - Cladis Method

Crack Detection Coating System for Concrete Structures - Cladis Method

Solving the issues of structural inspections! A method where cracks in structures glow under ultraviolet light.

The Cladis method is a painting system that detects "cracks" that occur on concrete surfaces. By applying this paint to structures in advance, cracks will emit light under special ultraviolet rays, making inspection tasks very simple, accurate, and cost-effective. The frequency of inspections can also be increased, allowing for precise understanding of structural changes. Emergency inspections immediately after disasters such as earthquakes or floods can be conducted swiftly. The two-layer coating emits light only at the cracked areas when exposed to ultraviolet light during inspections. The painting does not require special techniques or tools, making the inspection process straightforward and reducing work time. 【Features】 ○ Easy to apply ○ Glows under ultraviolet light ○ Easy crack detection ○ No oversight during inspections ○ Increased inspection speed For more details, please contact us or download the catalog.
