Flood Barrier Bags, Water-Activated, 6 Pack 830x430mm

Water-activated flood barrier bags expand fast to help block incoming water at doors, garages, and basements without hauling sand. Just place the bags where you need protection, wet to activate, and let the superabsorbent gel swell into a tight, weighted seal. Built with high-density non-woven fabric and reinforced stitching, these reusable sandless sandbags are designed for quick deployment during heavy rain and storm events.

• Delivers rapid protection as each bag expands to 3–4 in (76–102 mm) in about 10 minutes after activation


• Blocks water with superabsorbent polymer gel that expands up to 58x its weight for a tight seal under pressure


• Replaces messy sandbags for cleaner setup at doorways, basement entries, garage doors, and low thresholds


• Resists tearing with reinforced edge stitching and durable high-density non-woven fabric


• Includes 6 reusable flood bags for quicker coverage when water levels rise

Keep these flood prevention bags on hand for unpredictable weather and fast-moving leaks—store compactly, then activate only when needed. Once expanded, they form a heavy, low-profile barrier that helps redirect water away from entry points. For best performance, use with fresh water only and avoid salt water, lime, or calcium, which can affect the absorbent material. Set up before water reaches your threshold, and grab yours today for a ready-to-go emergency barrier.
