ロンタイ List of Products and Services

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. --------------------------------------------------------------------------------

Rontai's "Killket M Type" is a vegetation mat for cutting earth that allows for greening while preventing soil erosion. The non-woven fabric for erosion prevention adheres closely to the ground, suppressing soil particles, thus demonstrating a high effectiveness in preventing sediment runoff. Additionally, this product includes a sheet layer containing seeds and fertilizers, enabling greening while preventing erosion. 【Features】 ■ High erosion prevention effectiveness ■ Greening while preventing erosion ■ Equipped with soil improvement materials (High moisture-retaining materials are used in the fertilizer bag, and high water-retaining materials are used in the substrate bag) *For more details, please refer to the catalog or feel free to contact us. -------------------------------------------------------------------------------- Rontai offers free slope surveys at construction sites.

"Kilket" is a vegetation mat with one of the largest erosion prevention effects in the Longtai region. By using a special non-woven fabric, it achieves both erosion prevention and greening! ◆ Proven through artificial rainfall erosion tests ◆ The photo on the left shows three beakers lined up, containing runoff water from the artificial rainfall erosion test. The runoff water from our product Kilket (in the center) was almost clear, and no erosion was observed. By directing clean water into rivers and oceans, we protect ecosystems, which in turn safeguards people's lives. 【Features of Kilket】 - Adheres tightly to the ground due to its weight when water is absorbed, demonstrating excellent erosion prevention effects - Achieves both erosion prevention and greening - Compatible with all types of cut slope surfaces - Can be selected according to site conditions -------------------------------------------------------------------------------- Longtai offers free slope surveys at construction sites. For more details, please contact your nearest branch or sales office. --------------------------------------------------------------------------------

At Rontai, we handle products that are active in "early slope greening." The erosion control vegetation mat "Kilket M type" is a product designed for cut slopes, boasting one of our highest levels of erosion control effectiveness. You can choose from three grades according to the site conditions. Additionally, the erosion control vegetation sheet "Kilket S type" is a product for embankments and cut slopes that demonstrates excellent erosion control effectiveness. It can prevent sediment inflow into rivers and other bodies of water, achieving both erosion control and greening! Both products use a special polyester non-woven fabric. 【Features of Polyester Non-Woven Fabric】 ■ Mitigates rain drop impact ■ Exhibits high erosion control effectiveness ■ Allows plants to penetrate and grow ■ Quickly drains excess water ★ We are currently offering materials rich in construction photos! Please check the download for more details.

This is a catalog introducing the Killket series, which has one of the highest erosion prevention effects among Longtai products. The non-woven fabric used in Killket has a special structure. Rainwater passes between the two layers of non-woven fabric, quickly draining excess moisture! This prevents rainwater from accumulating on the slope surface. The catalog includes results from erosion tests conducted using artificial rainfall. If you want to protect slopes before heavy rain... this is a product we highly recommend for those facing such concerns! -------------------------------------------------------------------------------- Longtai offers free slope surveys at construction sites.

The "Ronkette DX" by Rontai is a vegetation mat that enables stable plant growth on slopes where root extension is difficult, such as soft rock and hard soil, while preventing surface erosion. This product allows for the selection of the number of base material bags to be attached according to soil hardness and slope, making it adaptable to different construction conditions at the same site! Additionally, it is equipped with a highly water-retentive soil amendment that protects seeds from drying out like a cover soil, improving plant germination and growth. 【Features】 ■ Achieves early greening ideal for disaster recovery ■ Can be installed in narrow spaces ■ Initial erosion prevention effect ■ Compatible with wire mesh products *For more details, please refer to the catalog or feel free to contact us.

In Hiroshima Prefecture, there is a system for registering technologies that contribute to "longevity, efficiency, and advancement" at all stages of investigation, design, construction, and maintenance of public civil engineering facilities, referred to as "innovative technologies." Under this system, "Kilket" has been registered in the efficiency category as "Recommended Technology, Category 3." It has been evaluated as the highest grade of registration, recognized as "technology with particularly excellent effects of utilization." Kilket contributes to the efficiency of work processes, disaster prevention, and disaster recovery at various sites due to its high erosion prevention effectiveness and greening performance! *This document can be viewed immediately via "PDF Download."

When designing greening for embankments, Are you worried about whether plants will grow? Do you want to prevent erosion caused by rainfall? Do you want to choose a method that is inexpensive, safe, and environmentally friendly? If you have such concerns, "Ronkett Keeper" can solve them! Ronkett Keeper is a turf product for embankments made by combining "straw" and "special non-woven fabric." It not only prevents soil and seed runoff with its high erosion control effectiveness but also creates a favorable environment for plant growth with its insulation and water retention properties. It is particularly effective for weak soil types against rainfall, contributing to "early greening" and "erosion prevention"! Additionally, the "tension" of the non-woven fabric makes it easy to cut, improving workability compared to our conventional products. *We are currently offering materials that include necessary cross-sectional drawings, floor plans, and work estimates for design! Please feel free to contact us.

"Ronket Keeper" is an artificial turf that prevents soil erosion and supports plant growth by attaching non-woven fabric to straw. While fully utilizing the insulation, water retention, heat retention, and environmental conservation effects of straw, the excellent weather-resistant non-woven fabric prevents the outflow of soil and seeds over a long period. Furthermore, the non-woven fabric creates a suitable "tension," making installation work and cutting easier, thus enhancing workability. 【Features】 ■ The non-woven fabric flexibly conforms to small unevenness, enhancing erosion prevention effects. ■ Uses non-woven fabric that allows plants to penetrate through. ■ Achieves a favorable growth environment for plants with the water retention, heat retention, and insulation effects of straw. ■ Available for purchase at a low price. ---------------------------------------- Rontai offers free slope surveys at construction sites.
