Development Report on the Alternative Method for Kagomatto: "River Web Method"

The alternative method to the Kagomatto construction method, "River Web Method," has been completed. It enables labor-saving and shortening of construction periods.
● Lightweight and Compact
Geo Web is lightweight and compact, making storage and transportation easy.
● Easy Construction and Shortened Construction Period
The construction method involves repeated tasks of unfolding, filling, and installing cover materials, allowing for a reduction in construction time. Compared to conventional methods, it can be constructed at a speed 4 to 6 times faster, contributing to a shortened construction period.
● Flexible Structure
The material is a honeycomb structure made of high-density polyethylene (HDPE), which excels in durability and flexibility. Additionally, Geo Web can be easily cut to the required dimensions on-site, allowing for construction that fits the site shape.
● Suitable for Riverbank Protection
When using a cover type, the cover material and Geo Web are integrated with connecting materials, making it adaptable to maximum flow rates of approximately 5 m/s. (Note: The applicable flow rate may vary depending on design conditions. Please consult us during the design phase.)

The River Web Method is a bank protection technique that combines three-dimensional geocells and stone materials to provide a landscape that considers the natural ecosystem. When using a cover type, it is possible to prevent the outflow of infill materials by connecting the cover material to the geoweb. (Applicable slope is less than 1:1.5)
