It starts with a weather warning.
The rain becomes heavier. Water begins pooling around your driveway, shed, garage, or business entrance. Traditional sandbags require sourcing sand, filling bags, lifting heavy loads, and spending precious hours preparing before floodwaters arrive.
But what if flood protection could be ready in minutes?
That’s exactly why StormBag™ was created.
StormBag™ is the innovative sandless sandbag designed to provide rapid flood protection without the labour, mess, and logistical challenges of conventional sandbags. Lightweight and compact when stored, each bag weighs only 1 lb (approximately 450 g) until needed.
Simply immerse the bag in water and watch it transform.
In less than three minutes, StormBag™ expands to approximately 33 lbs (15 kg), absorbing up to 4 gallons of water and forming a substantial 6-inch-thick flood barrier capable of helping divert and contain incoming water.
No sand.
No shovels.
No heavy lifting before the storm.
Just fast, reliable protection when you need it most.
Floodwaters don’t wait, and neither should your preparation.
StormBag™ provides a smarter, faster, and cleaner alternative to traditional sandbags, helping you protect your property with minimal effort and maximum convenience.
Keep StormBag™ on hand today and be ready when severe weather strikes tomorrow.
Fast deployment. Proven protection. No sand required. 🌧️🛡️🏠
StormBag™ has been trusted by:
The technology has been field-tested and approved for emergency flood protection applications, providing confidence when severe weather threatens.
StormBag™ takes up minimal storage space and remains lightweight until required.
Place the bag in water or allow it to absorb water directly from flood conditions.
Within minutes, the bag expands into a durable flood barrier ready to help protect vulnerable areas.
Stack multiple StormBags™ to build protective barriers around:
Store dozens of StormBags™ where traditional sandbags would be impractical.
Expands in under 3 minutes for emergency deployment.
Absorbs up to 4 gallons (approximately 15 litres) of water per bag.
Hydrates to approximately 6 inches thick, creating a substantial water-diverting barrier.
No sand, no dust, and no messy cleanup before deployment.
Keep StormBags™ stored and ready for emergency use.

StormBags will dry out after about two weeks in hot, dry conditions. If they are left exposed to water, they will stay at their full size indefinitely. They’re ready to provide flood protection as long as they remain wet.

StormBag uses a super-absorbent polymer that activates on contact with water. Place the 1 lb bag where needed, add water, and it expands to 33 lbs in 3 minutes — forming a solid flood barrier with no sand or shovels required.
The specs tell the story. StormBag creates a 6-inch barrier per layer; Quick Dam is rated at 3.5 inches stated (2–3 inches in practice). StormBag activates in 3 minutes; Quick Dam takes 5–10 minutes. StormBag holds FEMA and DHS approval for emergency flood mitigation; Quick Dam does not. For coastal flooding: StormBag must be activated with fresh water, but once fully hydrated, it effectively blocks salt water flooding including storm surge — an advantage for coastal homeowners where Quick Dam’s polymer does not activate properly. (Freshwater means any non-saltwater source — tap water, garden hose, rain, pool water, or standing floodwater. It does not need to be filtered or drinkable.)
StormBag is the tallest sandless sandbag available at 6 inches per layer when fully hydrated. Quick Dam reaches 3.5 inches stated height (typically 2–3 inches in practice). Traditional sandbags are typically 4–6 inches depending on fill level. For stacked flood barriers, StormBag’s 6-inch height per layer provides a meaningful structural advantage with fewer layers required to reach the same barrier height.
StormBag is the only sandless sandbag with both FEMA (Federal Emergency Management Agency) and DHS (Department of Homeland Security) approval for emergency flood mitigation. It has also been field-tested by National Guard units across the country. Quick Dam and FloodSax do not hold equivalent federal government approvals.
StormBag must be activated with fresh water — the super-absorbent polymer does not activate properly in salt water. However, once fully hydrated with a garden hose or other freshwater source, StormBag effectively repels and blocks salt water flooding, making it suitable for coastal storm surge and hurricane flood scenarios. Many competitors, including Quick Dam, use polymers that do not activate properly in salt water and do not claim effectiveness against salt water once activated — leaving coastal homeowners without adequate protection. Freshwater means any non-saltwater source — tap water, garden hose, rain, pool water, or standing floodwater. It does not need to be filtered or drinkable.
For a standard single doorway (3–4 feet wide), 4–6 StormBags create an effective barrier. For wider openings, see the Door Kit products or use the Storm Protection Planner to get a personalized recommendation for your specific opening size and flood risk.
