PROBLEM TO BE SOLVED: To prevent a wall from being pulled and improve the stability of a light weigh banking structure by reducing a total contraction amount and enables the simplification of a work process and reducing an execution time at a site and further make use of a time spent in waiting by forming blocks in a plant or the like when construction work is not carried at the site due to bad weather in an execution method for the light weight banking. SOLUTION: Molded blocks of foamed polyurethane of predetermined shapes are laterally laid in parallel behind a wall, and liquid foamed urethane is injected between the adjacent blocks and cured to form layered structures, and these layered structures are upwardly stacked to form a banking structure.
