The Sandbag That Needs No Sand.
1 lb dry. 33 lbs in 3 minutes. Just add water. StormBag is the fastest, easiest way to protect your home from floods, storms, and water damage.
Absorbs 4 gallons of water
Measures 23" x 13" x 6"
Traditional Sandbags Are a Nightmare
When a storm hits, every minute counts.
Backbreaking Labor
Traditional sandbags weigh 40–50 lbs each and require shoveling, filling, and tying. Deploying 50+ bags can take hours of exhausting physical work.
Too Slow for Emergencies
Floods don't wait. By the time you source sand, bags, and shovels, the water is already at your door. You need protection in minutes, not hours.
Storage & Disposal Hassle
Sand is heavy to store, messy to handle, and used bags become contaminated waste. You're left with a mountain of soggy, unsanitary bags after every event.
Three Steps. Three Minutes. Done.
No sand. No shovels. No heavy lifting.
Place the StormBag
Lay the lightweight 1 lb bag where you need flood protection — doorways, garages, or around your property perimeter.
Add Water
Submerge in freshwater or run a hose over the bags. The super-absorbent polymer inside does all the work.
Fully Protected
In 3–5 minutes, each bag absorbs 4 gallons and swells to 33 lbs — creating a solid flood barrier. Stack and build walls just like traditional sandbags.

How to Install a StormBag Door Kit
Common Questions
-
StormBags stay hydrated for about two weeks in hot, dry conditions. In cool, humid environments they last much longer. If left exposed to water, they stay at full size indefinitely.
-
It depends on the size of the area you're protecting. A standard single door takes about 5 bags. A double door needs 10. For a full property perimeter, a case of 25 gives you solid coverage. Our Door Kits come pre-configured with the right count for each opening size.
-
No. StormBags are designed for freshwater use only. The super-absorbent polymer does not activate properly in salt water.
-
Yes. That's the whole point. Each bag weighs only 1 lb dry — anyone can carry and position dozens in a short time. No crew required.
-
Yes — StormBags can be dried out and reused multiple times. Simply allow them to fully dry in sunlight, and they'll shrink back down to near their original size for compact storage.
-
Unused StormBags have a shelf life of 5+ years when stored in a cool, dry place away from direct sunlight. Keep them in their original packaging until you're ready to deploy.
