VEVOR Flood Barrier is a 4-pack set of water-activated flood bags designed to help block flooding around common entry points. Each bag measures 5 x 0.7 ft and uses a sheet water-absorbing gel filling to expand when exposed to water, forming a sandless barrier for practical flood prevention.
Built with high-density non-woven fabric and reinforced stitching, these absorbent barriers are made for repeated use in home environments such as doorways, basements, and garages. Before water absorption, each piece weighs 0.73 lbs, and after absorption it can reach 26.81 lbs per piece, with a maximum expanded height of 3-4 in. When not in use, the bags remain compact for easier storage and handling.
