Product Details
  • WATER-ACTIVATED FLOOD BARRIERS: Fresh water-activated in 5–10 minutes for fast, reliable protection against flooding and leaks around entryways, sliding doors, garages, storage units, and other at-risk areas.
  • NO SAND REQUIRED: Pre-filled with water absorbing Sand Gel that expands and stays in place—no sand, shovels, or heavy lifting. Folds flat and is lightweight before deployment for compact, easy storage.
  • ADAPTABLE COVERAGE: Expands up to 5 H inches—taller than the other guys—to absorb and divert water. Use singly, line up, or stack for larger zones around doors or leaking appliances; buy multiple for more coverage.
  • HEAVY-DUTY BUILD: Thick, puncture-resistant fabric is built to last unlike traditional sandbags that rip and leak. Sand Gel filler solidifies once set to resist leaking for dependable performance indoors or outdoors.
  • EASY TO USE: Lay in the path of slow-moving water to activate, or pre-soak in a bucket to prep for fast-moving water. Avoid contact with chlorine or salt water, which can prevent activation or deactivate the gel.

These sandless, water-activated flood barriers are must-have hurricane supplies for any storm prep kit. They lay flat for storage and expand on contact with fresh water, growing up to 5 H inches to help contain and redirect water quickly. Lightweight and compact when dry—often under 1 lb—they’re easy to transport, deploy, and remove when the threat passes. Simply add water to start activation, then line or stack them where protection is needed, from rain run-off and household leaks to faulty sprinklers and general flooding. Available in multiple lengths so you can tailor coverage to entryways, sliding doors, and single or double garage openings. Prepare for flood emergencies and protect your home from water damage with dependable, reusable-style convenience you can store between storms.
