It has ground support strength equivalent to high-quality sand and is highly durable.
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.

Company information
In recent years, awareness of environmental conservation and recycling has been increasing and becoming established. I believe that it is the responsibility of humans living in nature to protect natural resources and the environment—soil, water, and air—that are indispensable to daily life, as shared assets of the entire region and ultimately the entire planet. Tanaka Construction Co., Ltd. aims to contribute to local environmental conservation by developing, manufacturing, and selling recycling products that are beneficial for environmental preservation as a company that deals with "soil." As specialists in "soil," we want to contribute to the formation of a regional circular society by upholding the mottos: "No unnecessary 'soil' will be produced!" "Actively recycle usable 'soil'!" "Create high value-added 'soil'!" "Environmental regeneration!"
