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.

basic information
Why is the screw press method low-cost yet high-quality? Reasons for Low Cost: 1. Adoption of a special drill that generates no residual soil. 2. Realization of labor-saving with a dedicated machine operated by remote control (reducing the usual workforce from 4 to 2). 3. Incredible drilling speed! Continuous drilling up to 4 meters completed in just 2 minutes! Reasons for High Quality: 1. The pressing effect of the screw also compresses and strengthens the original ground. 2. A dedicated pressing pipe enables unparalleled pressing force for multi-layer compaction. 3. Air pressure prevents collapse and ensures the drilled hole stands more reliably. 4. Construction data is easily managed with a dedicated management device. 5. The crushed stone pile method also has the effect of suppressing liquefaction phenomena. 6. No cement is used, so there is no generation of hexavalent chromium. 7. Crushed stone incurs no future removal costs, and thinned wood is significantly cheaper compared to cement-improved piles.
