Water-Activated Flood Barrier Bags, 8 Pack, 480 x 435 mm

Water activated flood barrier bags expand fast to help block water at doors, garages, and basements without heavy sand. Each barrier uses a superabsorbent gel core that swells on contact with fresh water to create a tight seal under pressure. Designed for quick emergency flood protection, these reusable flood bags deploy in minutes and store compactly until needed. Reinforced stitching and high-density non-woven fabric help reduce tearing during setup and handling.

Keep these flood prevention bags on hand for storm season, plumbing leaks, or sudden runoff. Lay them where water enters, add fresh water to activate, and let the barrier build height and weight for a stable blockage. After use, allow them to dry for storage and reuse when conditions allow. Note: not recommended for salt water or exposure to lime/calcium, which can affect performance. Grab yours today and prep your home before the next surge.
