"PoliSoil Greening Works" is a slope greening method that firmly coats earth and sand slopes with an acrylic resin, providing rapid erosion prevention, guaranteed full greening, and high cost-effectiveness. *NETIS Registration: KT-210082-A As an early greening countermeasure after landslide disasters, it is effective in preventing erosion and muddy water generation during the restoration work period. << Examples of Adoption at Landslide Disaster Sites >> ■ Order: Mie Prefecture, October 2020 ■ Target: Emergency work at a hillside collapse site due to Typhoon No. 14 This method has a rapid erosion prevention effect, and by spraying it onto the soil, it dries and solidifies naturally within 1 to 3 days, making it resistant to being washed away even in heavy rain with hourly rainfall of several tens of millimeters. 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.

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.

We would like to introduce a case where our Polysoil Greening Work was implemented at a solar power plant. "Polysoil Greening Work" is a slope greening method that firmly coats soil and sand slopes with an acrylic resin, providing quick erosion prevention, reliable full greening, and significant cost-effectiveness. *NETIS Registration: KT-210082-A 【Challenges Before Construction】 Due to the geology of the entire area being sandy soil, soil would wash away with every rain, resulting in muddy water. 【Results After Construction】 - There was no runoff at all even during heavy rain on the third day after construction. - Full greening was achieved in about one month. *For more details, please refer to the materials available for download in PDF format or feel free to contact us.

In the construction sites of solar power plants, the runoff of soil and the collapse of slopes are significant challenges. Particularly, when natural disasters such as heavy rainfall or earthquakes occur, the risks increase. The stability of the slopes is crucial for the safe operation of the power plant and for considering the impact on the surrounding environment. PS Tensar Greening works to enhance slope stability by combining high-strength geogrids, rebar insertion, and polysoil backfill. 【Usage Scenarios】 - Construction sites of solar power plants - Areas requiring slope protection - Areas at risk of soil runoff 【Benefits of Implementation】 - Improved slope stability - Reduction of soil runoff - Long-term slope protection - Consideration for the surrounding environment
