• Special Construction Method

Improvement of construction-generated soil is carried out using stabilization treatments such as quicklime; however, there are limitations to the improvement efficiency for high water content clay. Granular improved soil (super soil) is created by granulating the soil with a polymer modifier called Soil Hard, and then solidifying it using quicklime. This process allows low permeability sandy soil and high water content clay to be reused as high-quality sand. For more details, please contact us or refer to the catalog.

• Water Supply Facilities

The weed prevention greening method combines weed prevention soil and creeping thyme to create a beautiful environment and achieve an eco-friendly solution that is gentle for everyone in the future. The raw materials for the weed prevention soil are purified sediment from the Tedori River water supply and construction waste soil. By mixing in a lime-based solidifying agent, we have reprocessed materials that would typically become industrial waste into soil that suppresses weed growth. Additionally, by mixing in tile waste, we can create color and also produce cushioning effects. Creeping thyme is a perennial plant from the family Lamiaceae, native to subtropical regions from Southeast Asia to South America (it grows wild in Okinawa, Japan). As a seedless plant, it helps protect native species in Japan. The effectiveness of the weed prevention greening method lies in the synergistic effect of the weed prevention soil that suppresses weed growth and the creeping thyme that inhibits the growth of other weeds, making it possible to promote greening in an environmentally friendly and economical way.
