Water-Activated Flood Barrier Bags, 4 Pack, 1530 x 210 mm

Flood barrier bags activate with water to create a fast, sandless shield for doorways, garages, and basements during heavy rain or storm runoff. This 4-pack expands in about 10 minutes, rising to a 3–4 in barrier that helps block seepage and redirect shallow flooding. Built with high-density non-woven fabric, reinforced stitching, and a superabsorbent polymer gel core, they’re designed for quick placement, tight sealing under pressure, and cleaner storage than traditional sandbags.

Keep these water-activated flood bags ready for sudden downpours, rising groundwater, or storm-season protection. Place them across doorways, along garage openings, or at basement entry points, then activate with fresh water and let them expand to form a barrier. They’re a practical alternative to messy sandbags when you need quick deployment and reliable coverage. Note: do not use with salt water, lime, or calcium as reactions may reduce performance. Grab yours today and prep your home before the next storm hits.
