Effective for drainage, permeability, and greening! High-performance slope protection method.
The "Sprayed Porous Concrete Method" uses a honeycomb-shaped flexible formwork (TerraCell) to spray porous concrete inside the formwork. This method forms a permeable, porous concrete that allows drainage across all cross-sections, preventing the retention of groundwater and suppressing the accumulation of spring water, thereby preventing loosening and collapse of the construction surface. When planting vegetation, it allows for easy greening promotion without hindering the establishment of the vegetation substrate. 【Features】 ■ Balances slope protection work and greening work ■ Vegetation is maintained over the long term ■ Lightweight and flexible, providing good workability ■ Allows drainage of water to the back across the entire slope ■ Controls the height of plants, reducing maintenance costs such as mowing *For more details, please refer to the PDF document or feel free to contact us.
