Due to the relatively high mountains and rivers in Korea, landslides and road loss are frequently caused by natural disasters such as floods and typhoons. As a result, various structures such as embankments, waterways or roads, slopes, and retaining walls of rivers and reservoirs are provided.

In general, structures such as the retaining wall have been conventionally installed by concrete construction. Such concrete construction is preferred in that it can form a structure suitable for the construction site, and can be firmly constructed. However, concrete structures require long periods of construction due to the ground conditions, and construction costs are expensive due to the stabilization work of the site and earthwork for installing various structures. In addition, the concrete structure is difficult to harmonize with the surrounding environment, and also caused the environmental destruction due to the difficult development.
