PURPOSE:To provide the water-stopping structure and water-stopping method of lightweight foamed body, which prevents the generation of cracking due to the initial drying of the lightweight foamed body employed for a fill or backfill and the like effectively. CONSTITUTION:In a water-stopping structure A for lightweight foamed bodies 1, placed in a construction area S, a water-stopping layer 3 consisting of a primary coating layer 3a, produced by anionic or nonionic asphalt emulsion, and a secondary coating layer 3b, produced by cationic asphalt emulsion and applied on the outside of the primary coating layer 3a, is formed on the surface of the light foamed bodies. |
