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

This flood barrier is a water-activated sandless solution designed to protect doorways, basements, garages and other vulnerable areas during flooding events.

Each barrier expands rapidly to 76–102 mm when activated with water, forming a tight seal against rising water. The four-pack includes barriers sized 1530 x 210 mm, ideal for standard doorway widths. The superabsorbent gel core expands up to 58 times its weight, creating a strong blockage that holds firm under pressure.

Deployment is straightforward: position the barriers in place and activate with water. Full expansion occurs within 10 minutes, making this solution practical for emergency response. The reinforced stitching along edges resists tearing and wear better than traditional sandbags.

After use, allow the barriers to air dry. They are fully reusable, collapsing back to compact form for storage. This saves considerable space compared to stockpiling heavy sandbags, and eliminates ongoing sand replacement and disposal costs.

Suitable for homeowners, renters and businesses seeking flood protection without the weight or mess of conventional sandbag systems. Works on concrete, tile and other smooth surfaces typical of home entrances.

To use: place barriers along the flood line, add water to activate expansion, and allow to set for complete protection.
