The "Soil Coat Spraying Method" is a technique that uses a mixed material consisting of the acrylic resin "PoliSoil α" combined with wood-based fibers to strongly coat soil slopes. It demonstrates effectiveness within 1 to 3 days after application, and the effects can last for about six months to one year. This method contributes to preventing erosion and soil runoff during construction, such as large-scale slope excavations. Since it can be applied using simple machinery, it is a method that can be easily adopted by contractors engaged in civil engineering work. 【Features of the Soil Coat Spraying Method】 ■ Achieves rapid effectiveness in erosion prevention and long-term durability ■ Prevents soil runoff even during heavy rains of several tens of millimeters ■ High cost-effectiveness and excellent economic efficiency ■ Compatible with various soil types ■ Since it becomes less prone to erosion, it allows for substantial slope reinforcement work to be carried out after the entire project is completed *For more details, please refer to the PDF materials or feel free to contact us.

The "PoliSoil Soil Improvement Method" is an effective slope greening technique that offers rapid erosion prevention, reliable full greening, and high cost-effectiveness, even for rock and hard soil. By adding acrylic polymer resin to the soil material, a solid foundation is achieved. It protects the surface by spraying it onto rock slopes or soil slopes. Since fertile black soil is solidified with acrylic resin and soil granulation agents, it is not washed away by rain. 【Features】 - Soil material: High-nutrition foundation of black soil, bark compost, and wood-based fibers - Rapid effectiveness that demonstrates erosion prevention within 1 to 3 days of natural drying after construction - Forms a robust greening foundation that combines erosion prevention and permeability - Protects slopes with a coating effect that does not wash away even in heavy rain with rainfall rates of several tens of millimeters - Its effects last approximately six months to one year, ensuring reliable greening regardless of the construction period ★ For soil slopes, we recommend the cost-effective "PoliSoil Greening Method." We also provide a catalog along with the "PoliSoil Soil Improvement Method," so please refer to the PDF materials for more details or feel free to contact us.

Moreover, the effective duration of its effect varies depending on natural conditions and soil types, but it is generally effective for about 6 months to 1 year, allowing for reliable greening even during unsuitable periods for vegetation work. 【Method Features】 Rapid erosion prevention / Guaranteed full greening / High cost-effectiveness *For more details, please refer to the PDF materials or feel free to contact us.

• Civil Engineering Method

The "BSC method" focuses on the fact that soil algae and other organisms that form BSC at the beginning of natural vegetation succession have an erosion prevention effect. It is an environmentally considerate technology that aims to establish BSC with native algae earlier to initiate vegetation succession. The presence of surrounding plants promotes the formation of natural vegetation according to soil conditions and climate. It avoids environmental impacts on native species, eliminates issues of genetic disruption for clonal propagation, and is easier to implement in areas with environmental conservation regulations. 【Features】 ■ Prevents the expansion of rill erosion (gullies) ■ The invasion of vegetation is influenced by surrounding environments, vegetation, and weather conditions ■ Construction is also possible in areas with snowfall *For more details, please refer to the related link page or feel free to contact us.

• Paving Materials

"Eco Clean Soil" is a natural soil-based paving material that preserves the natural landscape. The moisture retained by its water retention properties provides a cooling effect on the surface when it evaporates, and its permeability allows rainwater and other moisture to be supplied to the planted trees. Additionally, since its main component is natural soil and it does not contain harmful substances, it can be crushed and returned to the soil after use. The installation is simple, requiring only the preparation of the base, spreading the product, and watering. 【Features】 ■ Excellent landscape ■ Mitigation of global warming ■ Contribution to greening ■ Returnable to soil ■ Easy installation *For more details, please refer to the related link page or feel free to contact us.
