Soil Tech is a spray material developed for slope protection work. The erosion prevention type is used in greening methods such as seed spraying, topsoil spraying, and vegetation substrate spraying, protecting slopes and greening base materials from damage caused by rainfall, flowing water, and frost heave. <Features> 1. Low environmental impact Soil Tech is composed of biodegradable resin, which decomposes into water and carbon dioxide after a certain period due to the action of microorganisms. After the plants are covered, the spray material does not remain, making it effective as a microplastic countermeasure in river construction, hillside construction, and projects within natural parks, where consideration for the natural environment is necessary. 2. High soil improvement effect The granulated layer artificially formed by Soil Tech enhances the soil's water retention, thermal insulation, aeration, and nutrient retention, which are essential for plant germination and growth. The formed granulated layer will gradually be replaced by a natural granulated layer over time due to the action of the introduced plants and microorganisms, restoring the original natural environment. 3. Soil Tech has high binding strength, integrating soil and base material particles to protect slopes from damage caused by rainfall, flowing water, and frost heave. By adjusting the amount added during mixing, the erosion prevention effect can be enhanced according to the intended purpose.

Soil Tech (Sand Dust Prevention Type) is a biodegradable spraying material developed for the prevention of sand and dust. By creating a strong solidified layer on the surface, it prevents the occurrence of sand and dust in the surrounding area. The amount used can be selected according to the application site and prevention period, and after the prevention period, it decomposes due to the action of microorganisms. <Features> 1. Low Environmental Impact Soil Tech is composed of biodegradable resins, and after the sand and dust prevention period, it decomposes into water and carbon dioxide through the action of microorganisms. Since the solidified material does not need to be treated as industrial waste, it is suitable for temporary storage of excavated soil and within construction sites. It is also effective as a measure against microplastics, which have become a recent issue. 2. High Safety In the acute toxicity test for fish (medaka, static 96 hours: 10,000 ppm), it achieved the industry's highest survival rate of 100%. Since it does not contain harmful substances specified by the Industrial Safety and Health Act, there is no concern about soil contamination, making it safe for use near rivers, coastlines, and agricultural land. 3. Strong Durability Soil Tech has high solidification power, integrating soil particles on the surface by binding them together, thus preventing the occurrence of sand and dust.

Green pellets are spray materials for greening construction made from recycled cardboard. The wood fibers contained in cardboard, when used in conjunction with erosion control agents, prevent the loss of seeds and soil, and improve the soil's thermal insulation, water retention, and nutrient retention necessary for plant germination. <Features> 1. Environmentally friendly recycled material This is a recycled material utilizing the increasing amount of cardboard waste in recent years. The wood fibers that serve as the raw material for cardboard decompose after greening is completed, leaving no burden on the environment. 2. High expandability It is a dry type of curing material with low moisture content. After absorbing water, it expands quickly, allowing for a larger area to be covered with a smaller amount compared to wet curing materials. This can reduce transportation costs and labor. 3. Improved workability With a special tablet shape, there is no need to break it apart during material input, making it easy to measure. Additionally, it does not generate dust, preventing the material from scattering and dirtying the seeder or the site.
