Block and redirect slow-moving water without hauling sand or shovels. Flood Hero barriers store flat and lightweight, then expand when activated with fresh water, making them practical for doors, leaking appliances, garages, and other vulnerable areas.
Key features
Sandless non-woven fabric barrier filled with water-absorbing gel.
Activates in fresh water in about 5–10 minutes and expands up to approximately 3 inches high.
Dry barriers weigh less than 1 pound each for easier transport and compact storage.
Puncture-resistant outer fabric and gel filling designed to stay in place after activation.
Use indoors or outdoors for rain, household leaks, sprinklers, and general flooding.
Available in multiple lengths and pack sizes, including 2-, 6-, and 16-pack options depending on the selected configuration.
Lay the barrier in the path of slow-moving water or pre-soak it in a bucket before placement. Avoid chlorine and salt water, which can interfere with activation. These barriers are for water control, not a substitute for evacuation or professional flood protection during dangerous conditions.
