Erosion control vegetation sheet "Kilket S type" for cut and fill.

■■Maximum erosion prevention effect of embankment products■■Prevention of sediment runoff into rivers and other bodies of water■■

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. For more information, please contact your nearest branch or sales office. --------------------------------------------------------------------------------

What are the reasons for recommending products with straw?

Straw has various effects such as erosion prevention, insulation, water retention, heat preservation, and environmental conservation!

Rontai offers vegetation sheets and turf made from the natural resource "straw." Natural straw decomposes and returns to the soil, creating an organic layer that serves as an effective growth medium for plants, making it the best material for greening cover. 【Characteristics of Straw】 ■ Erosion Prevention By protecting slopes with straw, it prevents rainwater from directly entering the ground. ◎ Mitigation of raindrop impact ◎ Reduction of surface water flow speed ◎ Decrease in surface water due to straw's water absorption ■ Insulation and Water Retention It blocks direct sunlight and regulates moisture in the ground. ◎ Suppression of surface soil drying ◎ Blocking of direct sunlight ■ Heat Retention It protects seeds from low temperatures in winter. ◎ Protection of seeds from low winter temperatures ◎ Maintenance of germination rates during winter ■ Environmental Conservation Straw contributes to the conservation of the surrounding environment. ◎ After plant establishment, straw decomposes into nutrients ◎ Does not affect the original surrounding environment or ecosystem ◎ Captures airborne seeds Straw maximizes the use of natural forces to promote seed germination and plant growth. *For more details, please refer to the catalog or feel free to contact us.

Ron Tai's straw-wrapped product lineup

Here is the list of products made using natural resource "Wara"! ◎

Rontai offers vegetation sheets and turf made from the natural resource "straw." Natural straw decomposes and returns to the soil, creating an organic layer that serves as an effective growth medium for plants, making it suitable as a greening cover material. We have a proven track record across various regions in Japan. 【Benefits of Using Straw】 ■ Erosion Prevention → Reduction of runoff water due to straw's water absorption, slowing down flow velocity → Moisture gradually seeps into the soil ■ Insulation and Water Retention → Suppression of surface soil drying, blocking direct sunlight → Straw supplies moisture to the soil, enhancing water retention ■ Minimal Environmental Damage → After plant establishment, straw decomposes into nutrients ■ Insulating Effect → Protects seeds from low temperatures in winter, maintaining germination rates during overwintering *For more details, please refer to the catalog or feel free to contact us.
