ロンタイ List of Products and Services

Rontai offers proposals for weed control through greening! When it comes to weed control, we often think of "cutting," "killing," or "preventing"... Rontai suggests "growing"! By cultivating a special type of short-statured plant, we create an environment that is less conducive to weed growth. The benefits of using greening for weed control include: - Easier long-term management - Improved aesthetics - Erosion prevention Our company provides comprehensive support for the management of embankment greening. Why not aim for agriculture with less mowing together with us? *For more details, please download the catalog or feel free to contact us. -------------------------------------------------- Rontai conducts free slope surveys at construction sites.

When designing greening for cut slopes, "Are you worried about erosion caused by typhoons or heavy rain?" "There are variations in soil conditions even at the same site." "I want to carry out disaster recovery." "I want to shorten the construction period as much as possible." Do you have any such concerns? For those with such worries, Rontai proposes 'Ronkett DX'! Ronkett DX is a vegetation mat for soft rock I and hard soil. The special polyester non-woven fabric attached to the product alleviates the impact of raindrops on the slope over a long period, and the base material bag attached helps to reduce the flow velocity of rainwater on the slope surface. It is effective for sites where early prevention of slope erosion is necessary. Additionally, you can freely choose from four types of grades according to soil type, soil hardness, and slope gradient, so even if there are different site conditions within the same site, you can respond with products from the same series. Please feel free to contact us for more details! 【For such sites!】 ◎ I want to prevent erosion caused by heavy rain. ◎ I want to shorten the construction period. ◎ I want to prioritize early greening. ◎ I want to carry out disaster recovery. *We are currently providing materials that include necessary cross-sectional drawings, floor plans, and work quantities for design!

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.

"Shirokumatt" is a vegetation mat that uses natural palm netting as a covering material, which has thermal insulation, moisture retention, and erosion prevention effects.
