ロンタイ List of Products and Services

Ronquet DX is a vegetation mat for soft rock I and hard soil. The special non-woven fabric made of polyester attached to the product alleviates the impact of raindrops on slopes over a long period, while the substrate bag reduces the flow velocity of rainwater on the slope surface. It is effective for sites where early erosion prevention on slopes is necessary! 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 location, you can use products from the same series. *Please download the construction case collection from the form below. 【Features】 ◆ Disaster recovery through early greening ◆ Achieves speedy construction ◆ Initial erosion prevention effect ◆ Compatible with various site conditions -------------------------------------------------------------------------------- Rontai offers free slope surveys at construction sites.

This document is a collection of case studies on the restoration of slopes that have collapsed due to natural disasters, using vegetation sheets, vegetation mats, and vegetation sandbags. We, at Rontai, have been manufacturing the above-mentioned greening materials for "vegetation work" to protect slopes for over 65 years. These products can be installed manually, eliminating the need for large machinery, allowing for rapid greening protection even in narrow or small areas. As a result, many of our products are actively used in disaster recovery sites. The appropriate products vary depending on the site conditions. We have created materials that allow for comparison with your challenging site and help visualize the post-greening restoration. We focus on products specialized for "early greening and erosion prevention," which are crucial in disaster recovery work, and also introduce economical products and user-friendly vegetation sandbags!
