The "Killket S Type" from Rontai is an erosion control vegetation sheet that allows for greening while preventing soil erosion. The non-woven fabric for erosion control adheres closely to the ground, suppressing soil particles, which results in a high erosion prevention effect against sediment runoff. Since the flowing water moves through the non-woven fabric, it is possible to suppress the occurrence of muddy water. In an erosion test conducted with artificial rainfall for one hour, the runoff liquid from Killket was almost clear, and no erosion was observed. 【Features】 ■ High erosion prevention effect ■ Greening while preventing erosion ■ Available in seed-containing and seed-free types *For more details, please refer to the catalog or feel free to contact us. -------------------------------------------------------------------------------- Rontai offers free slope surveys at construction sites.
