Sandbags are bags filled with sand, often used for flood control, erosion prevention, and as barriers. They are typically made from durable materials like burlap or polypropylene, allowing them to withstand harsh weather conditions. When stacked, sandbags can create walls that help redirect water and protect properties from flooding. In addition to flood management, sandbags are also used in construction and military applications. In construction, they can provide temporary support or stabilize structures. In military contexts, sandbags are used to create protective barriers for personnel and equipment, enhancing safety in combat zones.
