Ground improvement agents that enable various eco-friendly improvements and soil paving without harming the environment!
Corn α is a new type of improvement material made from food additives and organic acids. By adding Corn α, it increases adhesion, accelerates compaction through rolling, and subsequently stabilizes these effects through microorganisms, enabling various improvements and soil paving that do not harm the environment. Waste soil can be treated as general leftover soil, eliminating the need for industrial waste disposal. 【Features】 ■ Harmless improvement material for humans and animals ■ Different improvement method from conventional solidifying agents ■ Reduction of leftover soil through improvement ■ Ensures permeability similar to natural ground ■ No impact on vegetation *For more details, please request materials or view the PDF data available for download.

basic information
【Features】 ○ Harmless improvement material → Composed mainly of malic acid, citric acid, and glucose, it is a food additive with organic acids that poses no risk of soil contamination. ○ Disposal of leftover corn α improved soil → Discarded soil can be treated as general leftover soil, eliminating the need for industrial waste disposal. ○ Improvement method different from conventional solidifying agents → The material and compaction accelerate consolidation to ensure and maintain the required strength. ○ Reduction of leftover soil volume through improvement → Unlike conventional solidification, corn α densifies through accelerated consolidation, resulting in a reduction in volume and soil quantity. ○ Ensures permeability similar to natural ground → Despite being high density, the material maintains permeability after improvement due to its effects. ○ No impact on vegetation → The initial pH of corn α improved soil is 4 to 6, becoming neutral through bio-proliferation. → The bio helps decompose nutrients for plants to absorb, resulting in optimal conditions for vegetation. *For more details, please contact us or download the catalog!

Company information
Ohsaki Construction Co., Ltd. was founded in 1902 by the first president, Kizō Ohsaki, who started a civil engineering contracting business in Kokura. Through the Tobu Railway Asakusa extension project in 1930, the company established itself as a specialized contractor. After World War II, it was one of the first in the industry to transition from manual labor to large construction machinery, leading to a significant increase in productivity during the subsequent period of rapid economic growth. Since then, as we moved from the Showa era to the Heisei era, the company has been involved in a wide range of construction projects, including high-rise buildings, temples and shrines, railways, highways, airports, and energy-related works. With over 100 years since its founding, our company has consistently built advanced technology and skills, along with tradition, to meet the needs of our customers as a specialized contractor in earthworks and structural works.
