Activities related to the dissemination of road slope disaster prevention technologies and methods in the Kingdom of Bhutan.
Our company implemented the "Dissemination, Demonstration, and Business Development Project for Road Slope Disaster Countermeasures Technology and Methods in Bhutan" under the Japan International Cooperation Agency (JICA) from August 2019 to June 2023. The Kingdom of Bhutan has about 70% of its land in mountainous areas, exposing it to risks of falling rocks and landslides, with slope disasters frequently occurring on its main infrastructure, the roads. This not only causes human casualties and creates isolated areas, but also significantly impacts local industries due to road disruptions. Furthermore, the lack of specialized engineers for rockfall and landslide countermeasures in the country, as well as the absence of companies capable of designing and constructing countermeasure facilities, poses a major challenge. In response, our company has worked on local demonstrations of products to stabilize road traffic and support steady economic development. Specifically, we installed two products, "Geo-Lock Wall" and "Macro Net," on-site. These efforts contribute to reducing human casualties from slope disasters, improving logistics efficiency, and fostering regional economic growth through industrial development. Moving forward, we will continue our activities to promote slope disaster countermeasure technologies and methods on roads in Bhutan and surrounding South Asian countries, contributing to economic development.
