Flood Bags are water-activated, sandless flood barriers designed to protect homes and property from rising flood waters. Easy to store and quick to deploy, they swell on contact to form a durable barrier without the mess of sand. Water-Activated, Sandless Design: Flood Bags absorb water on contact and swell into a solid barrier to stop and divert floodwater; not suitable for saltwater due to a reaction that causes deflation. Sizes and Swelled Dimensions: Standard bags measure 1 ft x 2 ft; Jumbo bags measure 1 ft x 4 ft; swelled size is 12 in x 24 in x 3.5 in for robust coverage. Capacity and Growth Time: Standard bags absorb about 4 gallons and reach full size within roughly 10 minutes; Jumbo bags absorb about 8 gallons and achieve full size in minutes. Materials and Safety: Contains a safe, non-toxic super absorbent powder that swells and gels water; environmentally friendly and designed to decompose over time. Deployment and Stability: Stackable in brick formations to increase wall height; eliminates the need for sand and heavy labor; suitable for ongoing protection when left in place. Pack Sizes and Storage: Available in 2-pack, 6-pack, 20-pack, and 120-pack; Grab & Go Buckets offer convenient storage and rapid deployment. These Flood Bags provide rapid, practical flood protection with minimal effort. They’re ideal for safeguarding entryways, basements, garages, and other vulnerable areas by creating a scalable barrier that expands as water rises. The sandless design simplifies preparedness—store them compactly, deploy quickly, and stack bags to match increasing flood threats. Safe for people and the environment, they offer a low-maintenance, repeatable solution for seasonal flood risk and emergency planning. Ships from supplier: Quick Dams
